    Personal ham radio experiences, station updates, operating stories, field notes, and amateur radio projects.

    The final straw was when I started noticing my signal reports on 20m were consistently a little soft. Not terrible, but guys on the other end would say things like "you're Q5 but a bit down compared to others." And I knew my antenna was decent. I'd modeled it, I'd trimmed it, the SWR at the radio was reasonable. But something felt off and I kept coming back to that sad, weathered collection of coax running from my shack window out to the fence post and up to the antenna.

    So I finally ordered a 100-foot roll of LMR-400 from a supplier I trust, a couple of PL-259 connectors rated for LMR-400, and a proper weatherproofing kit with self-amalgamating tape. Total came out to around $95 which, yeah, stings a little, but honestly I should have done this from the start instead of piecing things together.

    The Old Coax Was Worse Than I Thought

    Before I even started installing the new stuff, I cut open the end of that old RG-8X section near the barrel connector. The braid was greenish. Not like a little tarnish — actually corroded green in spots. And the center conductor had some discoloration too. I have no idea how long that coax had been sitting outside before I got it at the hamfest, but clearly it had seen better days. Water had definitely gotten in somewhere along the run. Lesson thoroughly learned: don't buy unmarked coax at hamfests unless you're absolutely sure what you're getting and plan to test it properly.

    I checked the barrel connector too and found one of the center pin connections was barely making contact. Honestly the whole thing was one good rain away from completely failing. It's a little embarrassing to admit because I know better, but sometimes you just want to get on the air and you tell yourself you'll fix it "later."

    Installing the LMR-400

    LMR-400 is noticeably stiffer than RG-8X, which took some getting used to. Running it around corners and through the window feedthrough required a little more patience. I used a standard oval feedthrough plate that I'd installed when I built the dipole — gave myself about 2 inches of clearance so the coax could make a gentle bend rather than a sharp one. You don't want to kink LMR-400, it doesn't forgive you the way smaller coax does.

    Putting on the PL-259 connectors for LMR-400 is a little different than for smaller cable. I used the solder type connectors, not crimp. There's a specific adapter/reducer that goes with LMR-400 and you have to prep the cable really carefully — strip the jacket back the right amount, fold the braid back cleanly, make sure the center conductor is long enough but not too long. I watched probably four different YouTube videos on this before I felt confident, and I still did a practice run on a scrap piece of coax first. My first attempt was okay but the solder on the center pin wasn't quite right so I redid it. The second one came out clean.

    I ran the whole 100 feet as a single unbroken piece, which was the whole point. No barrel connectors, no splices, nothing. Zip-tied it along the fence with UV-resistant ties at about 18-inch intervals and gave it a drip loop before it enters the feedthrough. Then wrapped both ends — the connector at the antenna feedpoint and the connector at the feedthrough — with self-amalgamating tape. That stuff is genuinely great. It fuses to itself and makes a completely waterproof seal. I've had regular electrical tape fail on outdoor connectors before, so I don't mess around anymore.

    The Results Were Actually Kind of Exciting

    First thing I did after hooking everything up was run through the bands with an antenna analyzer. SWR curves looked essentially the same as before, which was expected — the antenna didn't change. But then I got on 20m and started listening around. I noticed the noise floor seemed slightly better, which could be placebo, could be real. Hard to quantify on receive.

    On transmit though, I got a few signal reports within an hour of getting back on the air and three out of four of those contacts mentioned my signal was solid. One guy in Colorado said I was "full quieting" which was really satisfying to hear because he's someone I've worked before and I know he gives honest reports. I can't say with scientific certainty exactly how many dB I recovered by fixing the feed line, but the line loss difference between beat-up RG-8X with a bad connector versus clean LMR-400 over 100 feet is probably somewhere around 1.5 to 2 dB at 14 MHz. Not earth-shattering, but real.

    What I'd Do Differently

    If I'm being honest, I'd have bought good coax from day one. I know LMR-400 is pricier but over a 100-foot run to an HF antenna it's worth it. The price per foot sounds scary but you're not doing this every year if you do it right the first time. I'd also invest in a proper coax seal product earlier rather than hoping electrical tape would hold up.

    One other thing — I'm going to start keeping a short log of my coax runs, what type, when installed, connector type at each end, and any weatherproofing applied. Nothing fancy, just a notepad file. That way if I'm troubleshooting in two years I don't have to try to remember whether that outdoor connector was properly sealed or not.

    Anyway, if you've got a gnarly feed line situation you've been ignoring, take this as your sign to deal with it. It's not glamorous work and there's no big dramatic moment like hoisting up a new antenna, but a clean feed line is kind of the foundation everything else depends on. My 40m dipole and the 20m vertical both deserve better than what I was feeding them through, and now they've got it.

    Next project is probably going to be proper grounding and bonding at the station entry point. I've got a ground rod but the bonding between it and the shack panel is not great. That'll be its own adventure.

    The park I chose is a small state recreation area, nothing dramatic, but it qualified for the Parks on the Air program and more importantly it's close enough that if everything went wrong I wasn't stranded somewhere two hours from home. I pulled into the parking lot around nine in the morning thinking I'd have plenty of time to get set up before the bands got too noisy.

    What I Brought (And What I Forgot)

    My radio for this was a Xiegu G90 running at 20 watts. I know a lot of POTA folks go full QRP at 5 watts but I wanted a little more margin on my first outing. My antenna was a 40 meter end-fed half-wave that I bought as a kit and soldered up myself a few weeks ago. I'd tested it in the backyard and it seemed to work, SWR was reasonable on 40 and okay-ish on 20. I brought a 12 amp-hour lithium battery pack, a little antenna analyzer, coax, a notepad for paper logging because I didn't want to deal with a laptop outdoors yet, and way too many granola bars.

    What I forgot: my coax adapter. I had the antenna's BNC connector and the radio's SO-239 and nothing to connect them. Stood there in the parking lot staring at my gear bag for a solid two minutes feeling like a complete idiot. Fortunately I had a short patch cable with PL-259 on both ends that I'd thrown in as an afterthought, and I had a barrel connector in a little bag of miscellaneous hardware I keep in my car. It was awkward but it worked. Lesson one: make a checklist and actually use it.

    Getting the Antenna Up

    I'd planned to do a sloper, running the end-fed up at an angle from a tripod to a tree branch. The trees at this particular picnic area were not cooperating. First branch I could reach was maybe twelve feet up and the tree was weirdly positioned relative to where I wanted to set up. I ended up doing more of an inverted-V shape, sort of, with one end up on the tripod at about ten feet and the other end tied to a low branch. It was not elegant. The counterpoise wire was just laying on the ground which I've since read is actually fine for this type of antenna, so at least that part I didn't overthink.

    Getting the analyzer readings wasn't terrible. SWR was around 1.8 on 40 meters at the resonant point, which the G90's internal tuner handled without complaint. On 20 meters it was uglier but still matchable. I called it good enough and started operating.

    The Operating Part

    I'd decided to call CQ on 40 meters first since it was still morning and 20 might be better later. I picked a frequency around 7.245 MHz, listened for a couple minutes to make sure it was clear, and started calling. Nothing for about three minutes. I moved up a bit and tried again. Still nothing for a couple minutes, and then someone came back to me and honestly I got so flustered I fumbled my exchange. They were patient and we got through it. First contact logged. I may have done a small fist pump right there at the picnic table.

    After that things got a bit easier. I ended up with eleven contacts on 40 meters over about an hour and a half. A few hunters were clearly just running through activations quickly which I appreciated because they were efficient and easy to work. A couple of people wanted to chat a little which was also nice, and one person asked how my antenna was working which led to a genuinely useful two-minute conversation about end-fed antennas.

    I switched to 20 meters around eleven and got four more contacts, including one station that was quite far away geographically, which was exciting. Total for the day was fifteen contacts which is one more than the ten you need to count as a successful activation. I realize fifteen is not impressive by the standards of experienced activators who routinely log forty or fifty contacts in an outing, but for me it felt like a genuine accomplishment.

    Things I Would Do Differently

    The checklist thing I already mentioned. Beyond that, I'd bring a taller support for the antenna. Ten feet is pretty low and I think I lost some efficiency there. I've been looking at the lightweight mast options, the fiberglass push-up poles, and I think even a 20 or 25 foot mast would make a real difference. I'd also spot myself on the POTA website next time. I didn't do it this time because I was nervous and didn't want people to show up expecting a competent operator, but honestly the spotting system exists for a reason and it would have helped me get contacts faster.

    I also should have brought something better to sit on. The picnic table bench was fine but after ninety minutes my back was not happy. Some of those activators I see in photos have these little camp chairs that look much more reasonable.

    Would I Do It Again

    Yes, immediately, already planning the next one. There's something really satisfying about making contacts from a field setup that feels different from working from the shack. Maybe it's that you solved a bunch of small problems to make it happen. Maybe it's being outside. Probably both.

    I'm also thinking about trying to learn CW eventually so I can work the CW segments where there seems to be a lot of POTA activity, but that feels like a longer-term project. For now I'm going to keep doing SSB activations and try to get a little better at the process each time.

    If you're on the fence about doing your first activation, I'd genuinely say just go do it. You will forget something. Something won't work quite right. You'll work through it and you'll learn more in that one morning than you would from a month of reading about it. Or at least that's how it was for me.

    Thanks to everyone who came back to my calls last Saturday. You have no idea how much it meant to a very nervous first-timer.

    I made my first real DX contact. Like, not just a domestic contact that happens to be far away. An actual across-the-ocean, different-continent, holy-cow-did-that-just-happen contact. I'm still kind of buzzing about it.

    The Setup (Such As It Is)

    I should explain what I'm working with so this makes sense. My station is pretty modest. I've got a used mid-range HF transceiver that I picked up locally, running about 80 watts, and my antenna is a 40-meter dipole that I hung between two trees in my backyard. It's not fancy. One end is a little lower than I'd like because the tree on that side isn't as tall, so it's kind of a slanted dipole situation, which I've read is fine but I'm never totally sure how much it affects things. I also have a simple random wire that I've been experimenting with on 20 meters but the feedline situation is messy and I keep meaning to fix it.

    My noise floor is not great either. I live in a suburban neighborhood and there's some kind of switching power supply or LED driver nearby that puts a hash on certain parts of the bands. I've learned to live with it mostly.

    What Actually Happened

    So I'd been casually checking 20 meters in the evenings after work. I know that 20 meters is supposed to be the workhorse DX band, and I'd been reading about how propagation was improving as we move deeper into Solar Cycle 25. The solar flux numbers have been higher lately and I'd been watching the DX cluster on my laptop while listening, just trying to learn what good propagation actually sounds like.

    Last Tuesday around 7pm local time I tuned across 14.200 and something was different. The band sounded alive in a way I hadn't really experienced before. Signals were just cleaner, stronger, with that kind of presence where you can tell something is working right. I noticed a pile-up happening a bit further up and spun over to listen. Somebody was working a station in Europe — I caught the exchange enough to understand what was going on — and the European station's signal was honestly just remarkable. S7, S8 at times, coming in clear and full sounding.

    I sat there for probably twenty minutes just listening. The pile-up thinned out eventually and I thought, okay, this is the moment. I'm going to try.

    I waited for a gap, called once, and nothing. Called again. And then — I heard my suffix come back through the noise. He was asking for the full callsign. I gave it. He came back with a full exchange. Signal report and everything. I almost knocked my microphone off the desk.

    The whole QSO was maybe ninety seconds. But it was real.

    What I Learned (And Got Wrong)

    Here's the thing though. I almost missed the opening entirely because I didn't understand what I was looking at propagation-wise. I'd been checking the bands earlier that afternoon around 3pm and 20 meters seemed pretty flat to me — I was hearing some domestic stuff but nothing exciting. I almost didn't bother going back.

    What I didn't fully appreciate until I started reading more afterward is how different the band can sound at different times of day depending on where you're trying to reach. Transatlantic paths on 20 meters in my part of the country tend to open up in the late afternoon and into the evening, when the gray line and the ionosphere geometry are working in your favor. Checking at 3pm and giving up was almost a mistake that cost me the opening.

    I also didn't understand the solar flux index as well as I thought. I'd seen people talking about SFI numbers online but I was treating it kind of abstractly. Now I actually check it every day on one of the propagation sites. That week the SFI was up in the 180s which is pretty high, and there was low geomagnetic activity — the K-index was sitting at 1 or 2. I've since learned that combination is basically the recipe for good DX, especially on the higher HF bands. High flux, quiet magnetics. Simple enough, but nobody really spelled it out for me before. I had to kind of piece it together from forum posts and YouTube videos.

    The other thing I got humbled by: I tried again the next evening thinking lightning would strike twice. The SFI had dropped a little and the K-index had crept up to 3. Twenty meters was there but it wasn't the same. I heard Europe but weakly, and I didn't manage to get through any pile-ups. It was a good reminder that propagation is a moving target and you can't just bank on yesterday's conditions.

    Things I Want to Try Next

    I really want to try 17 meters now. From what I've been reading, 17 is kind of like 20's quieter cousin — less crowded, often good propagation during the same conditions, and because it's a WARC band there are no contests allowed so the pace is more relaxed. That feels more my speed while I'm still getting comfortable with DX operating.

    I've also been thinking about 15 meters. When the flux is high like it has been lately, 15 can apparently open up really well, and paths to Asia and the Pacific are possible in ways that 20 meters doesn't always offer from my location. I need to do more reading on that.

    And honestly I need to fix my antenna situation. A better dipole, maybe a fan dipole so I can cover multiple bands without retuning constantly, would make this all a lot less friction-y. Right now switching bands feels like a project. I want it to feel easy.

    Wrapping Up

    I know this is kind of a rambling first post. I mostly wanted to write it down while it was still fresh. If you're reading this and you're also newer to HF and feeling like DX is this intimidating mysterious thing — it kind of is, but it's also more accessible than I thought. Watch the propagation numbers, learn what the bands sound like when they're open versus when they're dead, and just actually transmit. That last part was the hardest for me.

    More to come when I have something worth sharing. Thanks for reading.

    It all started about three weeks ago when I was having trouble sleeping. I wandered into the shack around 5:30 AM with my cup of coffee, flipped on the radio just to see what was happening on 40 meters, and boom - there was this incredibly strong signal from New Zealand. I mean, this guy sounded like he was next door, but he was literally on the other side of the planet.

    That got me curious about what was actually happening propagation-wise. I'd heard about gray line enhancement before, but I'd never really paid attention to it. Most of my operating has been during normal evening hours or weekend afternoons. But this morning thing? This was different.

    Learning the Gray Line Magic

    So I started doing some reading and discovered that the gray line - that terminator line between day and night on Earth - creates this amazing propagation corridor. The D layer absorption is reduced along this line, which means signals can travel much farther with less attenuation. It's like having a temporary superhighway for radio waves.

    The really cool part is that this gray line is always moving around the Earth, so there's always some path that's enhanced. At my sunrise, I can work stations that are at their sunset on the same gray line path. And the signals are often just phenomenal.

    I started setting my alarm for about 45 minutes before local sunrise and spending that time on 40 and 80 meters. The difference compared to normal propagation is just incredible. Stations I can barely hear at other times are coming through with solid S7 or S8 signals.

    My Gray Line Routine

    Now I've got this whole morning routine worked out. I check the gray line maps online the night before to see what regions are going to be in the enhancement zone around my sunrise time. Then I set the alarm accordingly - though honestly, after three weeks of this, I'm starting to wake up naturally around 5:15 AM.

    The rig stays on 40 meters most of the time because that seems to be the sweet spot for gray line work from here. I've got my beam pointed toward whatever region looks promising based on the prediction maps. Europe has been fantastic - those guys are at their evening gray line when I'm at my morning one.

    Last Tuesday was absolutely incredible. I worked twelve European stations in about 45 minutes, all with fantastic signal reports both ways. Some of these were countries I'd never worked before. It felt like the bands were wide open, but it was really just that gray line magic working its thing.

    The conversations have been great too. There's something about that early morning time that brings out the more serious operators. Less of the quick contest-style exchanges and more actual conversations about stations, antennas, and propagation. I've learned more about antenna modeling in the past three weeks than I had in the previous year.

    Technical Stuff I've Learned

    One thing that's been really interesting is how much the gray line timing varies by frequency. 80 meters seems to need deeper darkness, so the enhancement window is narrower. 40 meters has this longer window of opportunity. I haven't had much luck with 20 meters during my morning sessions - it seems like it needs more daylight to really get going.

    The antenna pointing has been educational too. I assumed I'd just point toward Europe and call it good, but it turns out the gray line path isn't always the straight-line great circle route. Sometimes the enhanced propagation is following a curved path along the terminator line, so I've been experimenting with different headings.

    I also discovered that my antenna analyzer is pretty handy for this. The resonant frequency of my 40-meter dipole shifts slightly with temperature and humidity from the overnight conditions. A quick check and adjustment in the morning has improved my signal reports noticeably.

    The Downside

    The only problem with this new habit is that it's messing with my sleep schedule. I'm naturally a night owl, so getting up at 5:15 AM is not exactly natural for me. But the propagation is just so good that I can't resist. My wife thinks I've lost my mind, especially when she hears me talking to stations in Poland while she's trying to get ready for work.

    And there's the weather factor too. Gray line propagation seems to be even more sensitive to atmospheric conditions than regular propagation. Stormy weather really kills it, and we've had some nasty spring weather lately that's wiped out several promising mornings.

    I've also noticed that solar activity makes a huge difference. On days when the solar flux is higher, the gray line enhancement seems even more pronounced. But geomagnetic storms can kill it completely - learned that the hard way last week during some unsettled space weather.

    Looking Forward

    I'm planning to try this same technique for the evening gray line. The timing would be much better for my natural sleep schedule, and I should be able to work different parts of the world. Asia and the Pacific might be more accessible during my evening gray line period.

    I'm also thinking about trying some digital modes during these enhanced periods. FT8 and JS8 might be interesting with these stronger signals. Though honestly, I've been enjoying the voice contacts so much that I hate to give up the human interaction.

    This whole gray line discovery has really rekindled my excitement about HF operating. It's like finding a secret that's been hiding in plain sight. Sure, the early mornings are tough, but when you're working DX with signals that strong, the coffee tastes even better.

    Anyone else been experimenting with gray line propagation? I'd love to hear about your experiences and any tips for making the most of these enhanced conditions.

    I started with one of those popular computer programs that everyone recommends. You know the type - starts you off with individual letters at 5 WPM, builds up from there. Seemed logical enough. The first week went pretty well. I was feeling confident recognizing A, B, C, and the handful of other letters I'd learned. Dah-dit, dit-dah-dit, dah-dit-dit. Easy enough, right?

    Reality Check Number One

    Then I tried listening to actual CW on 40 meters during prime time. Holy cow. What I heard sounded absolutely nothing like the clean, perfectly-timed computer code I'd been practicing with. Real operators have different timing, different spacing, and some of them are flying along at what sounded like warp speed. I couldn't pick out a single letter, let alone a whole callsign.

    That's when an old timer at the local club set me straight. He told me I was making the classic mistake of learning letters instead of learning the rhythm and sound of each character. He said I needed to forget about counting dits and dahs and just let my brain absorb the patterns. Easier said than done when you're a methodical person like me who likes to understand exactly how everything works.

    Back to Square One

    So I started over with a different approach. Instead of that computer program, I found some Koch method training software that throws whole letters at you from the beginning at higher speeds. The theory is that you learn the sound of each character at full speed, rather than slowly building up from turtle pace. It felt like drinking from a fire hose at first.

    The breakthrough came during week three. I was getting frustrated and almost ready to quit when something just clicked while listening to the letter 'K'. Instead of thinking "dah-dit-dah," my brain just heard 'K' - like hearing your name called across a crowded room. That was the moment I understood what the old timer meant about rhythm and sound patterns.

    First Real QSO Attempt

    After four weeks of practice, I finally worked up the courage to answer a CQ on 20 meters. The other station was calling CQ at what sounded like a reasonable pace, maybe 12-13 WPM. I knew my sending was probably pretty rough since I'd been focusing mostly on receiving, but I had to start somewhere.

    My hands were literally shaking as I keyed up my response. I sent my call slowly and clearly, or at least I hoped it was clear. The other operator came back to me right away - success! He was very patient as I struggled through giving my name, QTH, and signal report. Looking back, that QSO probably took three times longer than it should have, but he hung in there with me.

    What really struck me was how different it felt from phone contacts. There's something almost meditative about the rhythm of Morse code. No background noise, no accents to decipher, no competing voices. Just clean, simple communication distilled down to its essence. I can see why some operators prefer it.

    Learning from Mistakes

    Of course, I made plenty of errors along the way. During my second CW contact, I completely blanked on how to send '9' and had to look it up mid-QSO. Embarrassing, but the other operator just waited patiently while I figured it out. The ham radio community really is forgiving of newcomers.

    Another time, I thought I was being smart by pre-programming some common phrases into my radio's memory keyer. But when I accidentally triggered the wrong memory and sent "QRT SK" instead of "QRL?", the frequency cleared out pretty quickly. Lesson learned: know what your keyer memories contain before using them on the air.

    I also discovered that my straight key technique needed serious work. My timing was inconsistent, and after about ten minutes my hand would cramp up. A local elmering session taught me about proper arm position and using wrist motion instead of finger movement. It made a huge difference in both comfort and character clarity.

    Current Status and Goals

    As of this writing, I'm comfortable copying around 10-12 WPM under good conditions, and I can send reasonably clean code at about the same speed. I've completed maybe a dozen QSOs on CW, ranging from quick signal exchanges to longer conversations about antennas and weather.

    My immediate goal is to get solid at 13 WPM, which seems to be the sweet spot where you can participate in most casual CW activity without holding anyone up. The next milestone after that will be 20 WPM, which opens up more contest and DX opportunities.

    I've also started experimenting with different keying devices. The straight key is good for learning proper timing, but I recently picked up a magnetic paddle to try with my radio's built-in keyer. It's taking some adjustment, but once I get the hang of it, I should be able to send much faster and with less fatigue.

    Advice for Other Newcomers

    If you're thinking about learning CW, my advice is to just start. Don't overthink it or wait for the perfect time or equipment. A simple computer program and your existing transceiver are all you need to begin. The hardest part is making that first contact, but once you do, you'll understand why so many hams are passionate about this mode.

    Also, don't be discouraged by the learning curve. Progress feels slow at first, but it does accelerate. Those breakthrough moments when your brain suddenly "gets" a new character or when you copy your first complete callsign without having to think about it - those make all the frustration worthwhile.

    Most importantly, get on the air as soon as you know enough letters to have a basic QSO. You'll learn faster from real contacts than from any computer program. The CW community is incredibly supportive of newcomers, and you'll find that most operators will slow down and work with you.

    Next month, I'm planning to try my hand at a CW contest - probably one of the smaller, less intimidating events to start with. Should be interesting to see how my skills hold up under that kind of pressure!

    I've been licensed for about eight months now, and up until last weekend I was using one of those multi-band verticals with a tuner. It worked okay for getting started, but 40 meters was always frustrating. I could hear the big guns coming through, but getting anyone to hear me back was hit or miss. The antenna was mounted on my deck railing about 12 feet up, which I know isn't ideal, but it was what I could manage in my HOA neighborhood.

    Planning the Inverted V

    After reading through the antenna handbook and watching way too many YouTube videos, I settled on an inverted V as my first wire antenna project. The theory seemed straightforward enough - basically a dipole bent down at an angle to fit in a smaller space. My backyard isn't huge, maybe 120 feet deep, so the inverted V seemed like a good compromise between performance and space requirements.

    For the center frequency, I aimed for 7.200 MHz since that's where I spend most of my time on 40 meters. Using the standard formula, that put my half-wave length at about 66 feet total, or 33 feet per leg. I decided to cut it a bit long and trim as needed - always easier to cut wire than to add it back.

    The biggest challenge was the support structure. I don't have any really tall trees in the right spots, so I ended up buying a 33-foot telescoping fiberglass mast from one of the ham vendors online. Not cheap, but I figured it was an investment in better performance. I set it up in the corner of my backyard where it's partially hidden by some bushes.

    Construction Details

    For the wire itself, I used 14 AWG stranded THHN wire from the hardware store. Some folks swear by antenna wire, but from what I read, regular house wire works fine and costs a lot less. I stripped about an inch off each end and soldered them to a center insulator I made from a piece of phenolic board I had lying around from an old electronics project.

    The feedpoint was the part I was most nervous about. I used a 1:1 current balun - just a simple ugly balun made with about six turns of RG-8X coiled up and secured with zip ties. I know there are fancier commercial baluns out there, but I wanted to keep the cost down and see how this simple approach worked.

    Getting the antenna up was definitely a two-person job. My neighbor helped me raise the mast while I guided the coax and guy wires. I secured the mast with three guy wires at the 20-foot level, using some landscaping stakes I drove into the ground. The antenna legs slope down at about a 45-degree angle to insulators tied off to fence posts on either side of the yard.

    Initial Testing and Tuning

    Once everything was up, I fired up my antenna analyzer to see what I had. The initial SWR curve showed resonance at about 6.9 MHz - a bit low, as expected. I trimmed about 18 inches off each leg and checked again. Still a little low. After three more trimming sessions, I got it centered right around 7.2 MHz with an SWR of 1.3:1 at resonance.

    The bandwidth was pretty good - SWR stayed under 2:1 from about 7.0 to 7.3 MHz, which covers most of where I operate. I can tune the rest of the band with my internal tuner without any problems.

    What really surprised me was how much quieter the receive was compared to my vertical. That antenna picked up every bit of noise from the house electronics, LED lights, and who knows what else. The inverted V is so much cleaner on receive. I can actually hear weak signals that were completely buried in the noise before.

    On-Air Results

    The proof was in the pudding when I got on the air that first evening. I called CQ and immediately had three stations come back to me - all giving me 59 reports. With the vertical, I was lucky to get 57 reports and often had to repeat my call multiple times. The difference was dramatic.

    Over the past few weeks, I've worked all across the US and into Canada on 40 meters with just 100 watts. Last weekend I even managed a contact with a station in Italy during a contest - something that never would have happened with my old setup. The antenna seems to have a nice low angle of radiation that's great for DX.

    One thing I noticed is that the pattern seems to favor the northeast-southwest direction, which makes sense given the orientation of the wire. I can work the east and west coasts really well, but stations to the north and south sometimes seem a bit weaker. That's the trade-off with a directional antenna, but overall I'm thrilled with the performance improvement.

    Lessons Learned

    If I were doing this project over again, I'd probably invest in a better antenna analyzer from the start. I was borrowing one from a club member, which meant I had to do all my trimming and testing in one afternoon. Having my own would let me fine-tune things over time.

    I also wish I'd planned the guy wire anchors better. I ended up with the stakes closer to the house than I'd like, and one of them is right in the middle of where my wife wants to plant flowers this spring. I may need to relocate that one before I get in trouble.

    The biggest lesson though is that antennas really do make all the difference. I spent months struggling with mediocre contacts, thinking it was just the way 40 meters was. Turns out I just needed to get some wire up in the air properly. This project has me motivated to try an 80-meter dipole next - if I can figure out where to put 130 feet of wire!

    For anyone thinking about their first wire antenna, I'd definitely recommend starting with an inverted V. The performance improvement over a compromise vertical was huge, and the project wasn't as intimidating as I thought it would be. Just take your time with the planning and don't be afraid to ask for help when you need it.

    The FT-891 arrived yesterday and I spent most of the evening getting it set up. I have to say, coming from the simple world of VHF/UHF repeaters, this thing is pretty intimidating! So many buttons, menus, and settings. The manual is thick enough to use as a doorstop.

    Why I Chose the FT-891

    I went back and forth between several radios for weeks. The IC-7300 kept coming up in reviews as the gold standard for new HF operators, but honestly it was just out of my budget range. The FT-891 seemed like a good compromise - it has most of the modern features I wanted like a waterfall display and decent built-in antenna tuner, but at a price point I could actually afford.

    I also liked that it's compact. My shack is really just a corner of my bedroom right now, so space is at a premium. The 891 fits nicely on my small desk without taking over the whole area.

    Setting It Up

    The unboxing was exciting, but then reality hit when I realized I needed to figure out how to actually connect everything. The radio came with a basic DC power cable, but I needed to get a proper power supply. After reading some forums, I ended up getting an Astron RS-35M. It's probably overkill for this radio, but I figured it would give me room to grow.

    Getting the power supply wired up was straightforward enough - red to positive, black to negative, nothing too scary there. The manual recommends heavy gauge wire for the DC connection, so I used 12 AWG which seems to work fine.

    The antenna situation is still a work in progress. Right now I have a simple wire dipole cut for 20 meters stretched between my house and a tree in the backyard. It's not pretty and it's definitely not optimal, but it's what I can do in my current living situation. The built-in tuner in the 891 seems to handle it okay, though I know I'm probably not getting the best performance.

    First Impressions

    The display is really nice compared to older radios I've seen at the club. The waterfall display actually helps me understand what's happening on the band in a way that just listening never did. I can see the signals visually and it makes tuning around much more intuitive.

    The audio quality through the built-in speaker is decent, though I've been using headphones most of the time since I'm operating in the bedroom and don't want to disturb anyone. The headphone jack is conveniently located on the front panel.

    One thing that's taking some getting used to is all the menu options. There are so many settings to tweak! I'm trying not to go overboard and change everything at once, but it's tempting. The noise reduction features are pretty impressive - much better than I expected from a radio in this price range.

    Making My First HF Contacts

    Last night I finally worked up the courage to make my first HF contact. I'd been listening for a few days getting comfortable with the bands, but actually transmitting felt like a big step. I found a station in Texas calling CQ on 20 meters and managed to work him without too much trouble. He was running high power and had a great signal, so it wasn't exactly a challenging contact, but it felt amazing to actually talk to someone hundreds of miles away with my own equipment.

    This morning I got up early and caught some interesting DX on 40 meters. I didn't try to work anyone since I'm still not confident with my operating procedures, but just listening to stations from different countries was fascinating. The propagation seems much different from what I'm used to on VHF.

    Things I'm Still Learning

    The antenna tuner is something I need to understand better. It seems to tune up fine on most frequencies, but I'm not really sure when I should and shouldn't use it. I've been reading about SWR and impedance matching, but there's definitely a lot more to learn there.

    Band planning is another area where I feel like a beginner again. On VHF it's pretty straightforward - repeaters are here, simplex is there. But HF has all these different sub-bands for different license classes and different activities. I bought the ARRL band plan chart to tape up next to the radio, which helps.

    I also want to get into digital modes eventually. The 891 has a USB port that's supposed to make computer interfacing easier, but I haven't tackled that yet. One thing at a time!

    Next Steps

    My immediate priority is improving my antenna situation. The wire dipole works, but I'd like something more permanent and efficient. I'm thinking about trying a fan dipole that would cover multiple bands, or maybe looking into a vertical antenna that would fit better in my small yard.

    I also want to join in on some of the nets I've been hearing. There's a local emergency net that meets twice a week, and it seems like good practice for improving my operating skills in a friendly environment.

    Overall, I'm really happy with the FT-891 so far. It feels like a big step up from my previous equipment, and I'm excited to explore what HF has to offer. The learning curve is steep, but that's part of what makes this hobby interesting. Every contact teaches me something new.

    If anyone has tips for a new HF operator or suggestions for getting the most out of this radio, I'd love to hear them!

    I picked a local state park about 45 minutes from home that I knew would be mostly empty on a cold February weekday. The temperature was hovering around 28 degrees, but I figured that would just make it more authentic, right? Famous last words.

    The Setup

    My portable kit is pretty basic - a 20-watt QRP transceiver, a 29-foot end-fed half wave antenna, and a small 7Ah sealed lead acid battery. I also brought along a folding table, a camp chair, and what I thought was adequate cold weather gear. The antenna support was going to be a 20-foot telescoping fiberglass pole that I'd been wanting to test out.

    Getting to the park was easy enough, and I found a nice spot near the picnic area with some trees for antenna support. That's when reality started setting in. First lesson learned: those little plastic clips that come with telescoping poles? They don't work so well when your fingers are numb from the cold. I spent about 15 minutes fumbling around trying to get the sections locked in place while wearing gloves.

    The antenna went up easier than expected once I got the pole situation sorted out. I tied off one end to a picnic table and used the pole to get the other end up about 18 feet. Not perfect, but it looked reasonable. The counterpoise wires just laid on the frozen ground.

    First Contact Jitters

    Once everything was connected and I'd done a quick SWR check (thankfully it was under 2:1 across 20 meters), it was time to try making some contacts. I tuned around 20 meters looking for a good frequency and found a quiet spot around 14.255. Then came the moment of truth - calling CQ for the first time in the field.

    "CQ Parks on the Air, CQ POTA" felt strange coming out of my mouth, but within about 30 seconds I had my first response. A station from Tennessee came back to me with a solid 5-7 signal report. I was so excited I nearly fumbled the exchange, but managed to get his info logged properly. One down, nine to go for a valid activation.

    The next hour was a blur of contacts. I worked stations from all over the east coast and even got a few from the midwest. The little QRP rig was performing better than I expected, and most stations were giving me solid copy reports. I was starting to feel pretty confident about this whole POTA thing.

    When Things Go Sideways

    About 90 minutes in, just as I was working my 12th contact, disaster struck. A gust of wind caught the antenna pole and sent it crashing down. The antenna wire got tangled in some nearby bushes, and I could see one of the connector crimps had pulled loose.

    This is where being prepared really matters, and honestly, I wasn't as ready as I thought. I had brought a small toolkit, but trying to re-crimp a PL-259 connector in near-freezing weather with numb fingers turned out to be way harder than doing it comfortably at my home workbench.

    It took me about 20 minutes to get everything sorted out and the antenna back up. During that time, I learned another valuable lesson: bring backup connectors and maybe even a backup antenna. Several stations had been calling me when the antenna went down, and I felt bad about just disappearing from the frequency.

    Wrapping Up

    Despite the antenna mishap, I managed to log 18 contacts total before packing up. My hands were getting too cold to write legibly in my logbook, and the battery was starting to show signs of the cold affecting its capacity. The voltage had dropped from 12.8 to about 11.9 volts, and I could tell the transmitter wasn't quite as punchy as it had been earlier.

    The drive home gave me plenty of time to think about what went well and what I'd do differently next time. The QRP transceiver performed great, and the end-fed antenna worked better than I expected for being so close to the ground. But I definitely need to invest in better cold weather gear and maybe bring some hand warmers.

    Lessons for Next Time

    First, dress warmer than you think you need to. What feels comfortable for a quick walk to the mailbox gets pretty miserable after sitting still for two hours. I'm thinking about getting one of those propane heaters that ice fishermen use.

    Second, have backup plans for everything. Extra connectors, maybe a simple wire dipole as a backup antenna, and definitely more than one way to support the antenna. I'm considering getting some of those heavy-duty tent stakes to guy the pole down better.

    Third, practice the setup at home first. I thought I knew my equipment pretty well, but there's something about being in the field that makes everything take longer than expected. Next time I'll time myself setting up in the backyard a few times before heading out.

    Finally, invest in a better logging system. Writing in a paper logbook with cold fingers was not ideal. I'm thinking about trying one of the phone apps that can handle POTA logging, or at least getting a clipboard and some pre-printed log sheets.

    All in all, it was a great experience despite the challenges. There's something really satisfying about making contacts from a park bench in the middle of nowhere with just a small radio and some wire. I'm already planning my next activation for a warmer day!

    Anyone else have stories from their first POTA activation? I'd love to hear about other people's learning experiences in the comments.

    When I first got my license back in February, I was so excited to get on the air that I immediately bought a Baofeng UV-5R and started hitting the local repeaters. That was fun for a while, but I kept hearing about HF and all the amazing contacts people were making around the world. The problem was, I had absolutely no idea where to begin with putting together an HF station.

    The Research Phase (aka Going Down the Rabbit Hole)

    I spent weeks watching YouTube videos, reading forums, and asking questions on Reddit. Everyone seemed to have different opinions about what radio to get as a first HF rig. Some people swore by the Yaesu FT-450D as a great starter radio, others recommended the Icom IC-7300 even though it was more expensive. A few suggested looking at older rigs like the Kenwood TS-440 or TS-940.

    The antenna situation was even more confusing. Dipoles, verticals, loops, beams - my head was spinning. And don't even get me started on all the discussions about feedline, SWR, and antenna tuners. I was starting to feel overwhelmed and wondering if I'd bitten off more than I could chew.

    Making Some Decisions

    Finally, I decided to stop overthinking it and just pick something reasonable to get started. My budget was around $800 for everything, which I knew wasn't huge but should be enough for a basic setup. After reading countless reviews, I settled on a used Yaesu FT-450D that I found on a local ham swap page for $350. The seller was super nice and even threw in a desk microphone.

    For an antenna, I decided to start simple with an end-fed half wave. I know there's some controversy about these antennas, but they seemed like a good compromise between performance and ease of installation for someone renting an apartment. I ordered a 49:1 UnUn kit from a small company and planned to build my own wire antenna.

    Setting Up the Shack

    The spare bedroom in my apartment isn't huge - maybe 8x10 feet - but it was enough to set up a basic station. I found an old wooden desk at a thrift store for $25 and spent a weekend sanding and refinishing it. It's nothing fancy, but it gives me plenty of room for the radio and has drawers for storing accessories.

    One thing I didn't anticipate was how many cables and accessories I'd need. Besides the obvious power cable and microphone, I ended up needing coax, an SWR meter, and various adapters. The local ham radio store was incredibly helpful - the owner spent almost an hour with me making sure I had everything I needed and explaining what each item was for.

    Power was another consideration I almost missed. The FT-450D needs 13.8V DC, and while it came with a cigarette lighter adapter, I knew I needed a proper power supply for base station operation. I found a good deal on a used Astron RS-20A linear supply. It's probably overkill for the FT-450D, but I figured it would handle any future radio upgrades.

    The Antenna Adventure

    Installing the antenna was definitely the most challenging part of the whole project. My apartment is on the second floor, and I don't have access to the roof or a yard where I can put up poles. I ended up running the end-fed wire from my shack window, around the building to a tree in the courtyard, and then back to another tree. It's not ideal, but my SWR readings are reasonable on most bands.

    The 49:1 transformer is mounted in a small weatherproof box just outside my window. I had to get creative with the mounting since I couldn't drill into the building, but some heavy-duty double-sided tape and a couple of zip ties seem to be holding everything securely.

    Getting the feedpoint impedance right took some experimenting. The antenna calculator said I needed about 65 feet of wire for 40 meters, but I ended up having to trim it a few times to get the SWR down to acceptable levels. Thank goodness for the SWR meter - I would have been completely lost without real-time feedback.

    First Contacts and Lessons Learned

    After all the setup work, making my first HF contact was incredibly exciting. I started on 20 meters in the afternoon and was amazed at how many signals I could hear. My first QSO was with a station about 500 miles away - not exactly DX, but it felt like magic compared to the 5-mile range I was used to with my HT.

    I quickly learned that my antenna works much better on some bands than others. It's pretty good on 40 and 20 meters, okay on 15 meters, but pretty awful on 80 meters. I think the apartment environment and low height are hurting performance on the lower bands. That's something I'll have to work on in the future.

    One surprise was how much difference the time of day makes. I'd heard about propagation in my license study, but experiencing it firsthand was eye-opening. 20 meters that was dead in the morning would come alive in the afternoon with stations from all over the country.

    What's Next

    Now that I have a functioning HF station, I'm already thinking about improvements. I'd love to try a different antenna design - maybe a magnetic loop for better performance in this limited space. I'm also interested in digital modes like FT8, which means I'll need to figure out the computer interface situation.

    The whole experience has been incredibly educational. While the technical aspects were sometimes frustrating, there's something really satisfying about building a station piece by piece and learning how everything works together. If you're a new ham thinking about getting into HF, my advice would be to start simple and don't let perfect be the enemy of good. You can always upgrade and improve things later, but getting on the air and making contacts is what this hobby is all about.

    73 and hope to work you on the bands!

    The whole thing started around 6 PM when the National Weather Service issued the first severe thunderstorm warning for our county. I was monitoring the local repeater like we're supposed to do during weather events, and within an hour things escalated to a tornado watch. Our ARES net control station came on the air and started coordinating reports from storm spotters across the county.

    When the Power Went Out

    About 7:30 PM, we lost power. Just like that - one minute I'm listening to weather reports on my base station, and the next minute I'm sitting in complete darkness. This is where my first big lesson learned kicked in: my backup power situation was not nearly as good as I thought it was.

    I had a small 12V sealed lead acid battery that I thought would be plenty. Wrong. The FT-891 draws about 20 amps on transmit, and that little 18 amp-hour battery lasted maybe 45 minutes of actual emergency net operation. I was transmitting position reports and storm observations, but I had to keep it really brief to conserve power.

    Luckily, I remembered I had a 12V power supply in my car, so I ran an extension cord out to the driveway and powered my radio from the cigarette lighter. Not exactly elegant, but it worked. Made a mental note to invest in a proper deep cycle battery and maybe look into solar charging options.

    Learning the Weather Net Protocol

    Being new to emergency communications, I wasn't entirely sure about the proper protocol for weather nets. Our net control did a good job explaining things, but it was definitely different from the casual ragchewing I was used to on HF.

    The key things I picked up were keeping transmissions short and to the point, using your location clearly, and only reporting what you actually observe - not what you think might be happening. When I saw what looked like a funnel cloud forming about two miles south of my QTH, I reported it as "possible funnel cloud development" rather than calling it a tornado. Good thing too, because it turned out to be just a low-hanging cloud formation.

    One thing that really impressed me was how organized everything was. Net control kept a log of all spotters checking in, assigned specific areas for people to monitor, and maintained regular contact with the National Weather Service office. It felt like being part of something important, which I guess it really was.

    Equipment Challenges

    My antenna setup held up okay during the storm, but I definitely need to do some work there too. I've got a simple dipole for 40 and 80 meters up about 25 feet, and it performed fine. But for VHF/UHF emergency work, my little 2-meter vertical on the roof seemed pretty marginal. When the winds picked up, I started getting reports that my signal was weak and fluttery.

    I think the coax connections need some serious weatherproofing attention. I used electrical tape when I installed everything last year, and apparently that's not cutting it. Going to invest in some proper coax seal and maybe upgrade to better quality connectors.

    The handheld radio I keep in my go-bag worked great though. Having that as a backup when I was dealing with power issues for the base station was clutch. Battery life on receive was excellent - lasted the entire four-hour weather event with plenty of juice left over.

    Communication with Family

    One unexpected challenge was keeping my family informed about what was happening while also participating in the weather net. My wife kept asking questions about the storm, and I was trying to monitor both the repeater and NOAA weather radio at the same time. In hindsight, I should have set up a separate scanner for weather radio monitoring and used my handheld to stay in touch with the emergency net.

    We talked afterward about developing a better family communication plan for severe weather. She needs to understand that when I'm operating in an emergency capacity, I might not be immediately available to answer questions. But I also need to make sure she has access to weather information independently.

    What I'm Doing Differently

    Based on this experience, I've got a whole list of improvements to make. First priority is definitely backup power - looking at a 100 amp-hour AGM battery and a proper charging system. I've been reading about LiFePO4 batteries too, but they're pretty pricey for a good setup.

    Second is antenna improvements. Planning to put up a proper dual-band base antenna for VHF/UHF, probably a Diamond X-50 or similar. The height advantage should help with coverage during emergency operations.

    I'm also going to start participating in more training exercises. Our ARES group does monthly drills, but I've only made it to one so far. After experiencing a real event, I can see how much more comfortable I'd be with regular practice.

    Final Thoughts

    Despite all the things that didn't go perfectly, I'm really glad I was able to contribute something useful during the storm. The weather net handled reports from about fifteen spotters across the county, and several of the observations helped the National Weather Service issue more targeted warnings for specific areas.

    The storm ended up producing some minor wind damage and heavy rain, but no confirmed tornadoes in our immediate area. The funnel cloud I thought I saw never developed into anything serious. But knowing that our amateur radio network was there providing real-time ground truth to the professionals felt pretty rewarding.

    Looking forward to the next weather event now - hopefully with better backup power and more experience under my belt.
