QRP Master

okay so ive been licensed for about 8 months now and ive been making contacts pretty regularly, mostly HF on 40 and 20 meters, some FT8 and the occasional SSB QSO when im feeling brave enough to actually talk. but the whole QSL confirmation thing is honestly still confusing to me and i want to make sure im not missing something important. so from what i understand, Logbook of the World (LoTW) is the ARRL thing where you upload your log and if the other station also uploaded theirs the contact gets confirmed digitally, right? and eQSL is like a different system that does something similar but its not as accepted for awards? and then physical QSL cards are the old school paper ones you mail through the bureau or direct? my question is basically do i need to be doing all three or is LoTW enough for most purposes. a few guys at my local club said i should just do LoTW and not worry about the rest but then someone else said eQSL is fine for just collecting confirmations if you dont care about official awards. i did register for LoTW a few weeks ago and got my certificate sorted out but i havent uploaded anything yet because i wasnt sure if i had to do anything special with my log first. also does anyone actually still send physical cards? i got one in the mail last week from a station in Japan and it was honestly pretty cool, wasnt expecting it at all

the stereo audio thing — yeah it takes probably 5 or 6 serious contests before it stops feeling like you're going insane. stick with it though because once it clicks you really can monitor both at the same time without consciously thinking about it. your brain learns to kind of background-process the radio 2 audio while you're focused on radio 1. took me two full contest seasons to actually trust it. on the timing question, what helped me was thinking of it less as switching and more as filling dead air. when youre running and you send the callsign and the exchange and now youre waiting for the reply — that's your window. that turnaround time is real time you can be doing something. even if you just tune across a few khz on radio 2 and log a quick S&P qso before your radio 1 station comes back, thats a qso you wouldnt have had. the guys doing this really well can sometimes close a full exchange on radio 2 in the time it takes a station to decode their exchange and send a reply on radio 1. its tight but it works. what i'd actually suggest is run a practice session outside of a real contest, just turn on both radios during normal band activity and try the rhythm without any pressure. your rate will be garbage at first because youre training muscle memory not trying to win anything.

so i've been licensed about 8 months now and ive been doing some of the smaller state QSO parties just to get a feel for things but honestly CQ WW is kind of intimidating me. the sheer number of stations calling is wild, i tried tuning around during last years event just to listen and it was wall to wall signals on 20m. i barely knew what was happening. my setup is pretty modest, running a 100w into a dipole up about 30 feet. i know im not going to win anything but i kind of just want to participate and maybe work some DX i wouldnt normally get. is it even worth jumping in with this kind of station or will i just get buried? also curious how people handle logging during a contest like that, im still using paper for most of my operating which probably isnt ideal also totally unrelated but does anyone know if ARRL Field Day counts as a contest or not, i keep getting different answers on that

that weird noise could have been DTMF or maybe it was linked to an Echolink or IRLP node and you were catching the tail end of someone's audio from another city. happened to me when I first started and I had no idea what I was hearing lol. some of the linked systems sound really strange if you dont know what youre listening for.

yeah i was in the same boat not too long ago. honestly just get the LoTW cert sorted first thats the main thing. i put it off for like six months and then kicked myself because i had all those unconfirmed contacts sitting there. the eQSL stuff is fun too though, some of the cards people design are really cool and its kind of nice to have something visual to look at even if its just on a screen. paper cards i've only sent a handful of times for special contacts, like my first DX or whatever. the bureau is supposedly cheaper but slow, direct mail is faster but you're paying postage and some IRCs if it's overseas which adds up

so ive been running a mag mount dual band on my F-150 for about two years now and its been fine mostly but i keep reading that a proper NMO mount through the roof is the way to go for signal. the mag mount sits on the roof toward the back and i get decent ground plane but i notice on longer drives the thing shifts a little and i have to readjust it when i get home. anyway im thinking about doing a proper install with an NMO and running the coax through the weatherstripping down to the radio under the seat. the truck is a 2021 so im a little hesitant to drill through the roof obviously. has anyone done this recently on a newer truck and was it worth it versus just living with the mag mount? i mostly do local repeater work and some simplex when im out hiking access roads. not contesting or anything serious just want reliable comms. also not sure if it matters but im running a Diamond NR770HNMO or whatever the comet equivalent is, cant remember right now.

that first QRP contact on homebrew gear is something else isnt it. i remember mine clearly and it was years ago. for POTA i honestly just use a 20m end fed half wave most of the time, throw it up in a tree with a fishing line and a small 9:1 unun i wound myself. works great for 20 and you can kinda fudge it on 40 if you mess with the tuner. keep it simple when youre portable, every ounce matters when youre hiking in. the ubitx has its quirks for sure but people have done some really nice things with the firmware over on groups.io, worth poking around over there if you havent already. there was a guy who did a whole writeup on improving the low band receiver performance. not sure if its totally necessary but interesting stuff

yeah i had almost the exact same issue with an NE602 build a while back, turned out my bypass caps were too far from the supply pins. also worth checking if your audio stage is picking up RF from the oscillator, if the LM386 input lead is too long it acts like an antenna basically. i ended up having to shield the VFO section with a little tin can just to clean things up. not pretty but it worked lol

so i just passed my technician exam last week and im trying to figure out what handheld to buy first. ive been looking around and there's just so much stuff out there it's kind of hard to know where to start. everyone in my local club seems to have different opinions and now im more confused than before lol some people are saying just grab a baofeng uv-5r to learn on, others are saying thats a waste of time and i should save up for something like a yaesu ft-65 or maybe the vx-6r which looks really nice but also costs way more. i dont really know what features actually matter vs what's just nice to have. like do i actually need dual band right away? and what about the programming software, i heard some radios are way easier to program than others which seems important mostly i'll be using it to check into the local repeater and maybe bring it hiking. any thoughts appreciated, i dont have a huge budget, probably around 50-75 bucks to start

Field Day is genuinely the best starting point in my opinion, way more forgiving than CQ WW and most clubs are happy to have extra operators even if you're just learning the rhythm of contest exchanges. the exchange is simple too, just your class and ARRL section, nothing crazy to memorize that said if you want to jump into CQ WW, your 40m dipole will absolutely work. october conditions are usually decent and you'll be surprised how many contacts you can make even running 100 watts to a wire. the exchange is just signal report and CQ zone, like 59 14 or whatever zone you're in. just go in expecting a learning experience and not a score and you'll have a blast. i did my first CQ WW with a g5rv and a kenwood ts-570 and still managed like 200 contacts over the weekend SOTA is kind of its own universe — activators go up hills and summits and try to make 4 contacts to qualify the summit, and chasers log them. it does count for your regular logs but it's not really tied into the big HF contests the same way. totally worth doing though if you like hiking

yeah 44 QSOs is the minimum for a valid activation, you nailed it. and honestly 47 on a first activation with a wire in a tree is pretty solid. i remember my first one was kind of a mess, took me almost 4 hours to get to 44 because i didnt really know how to work a pileup and kept letting the frequency go quiet for too long. for logging in the field i switched to just using a clipboard with pre-printed log sheets and a decent pen, sounds old school but its faster for me than fumbling with a phone app when signals are coming in fast. some people swear by HAMRS or Fast Log Entry but you have to have the park reference loaded ahead of time like you said. what i do now is download the wwff reference kml file every few weeks so i have the current list, and before any activation i just make sure the reference is already in whatever app im using. saves the scramble later. the EU contacts on 17m from a wire in a tree is the real story here though, 17m can be magic sometimes especially in the afternoon when the greyline is doing interesting things. good stuff, keep activating

okay so ive been licensed about 8 months now and i keep hearing people on the club net talking about solar flux and the bands being 'open' or 'closed' and i nod along like i know what theyre talking about but honestly i only kind of get it. like i understand the sun affects the ionosphere and that affects HF propagation, that much i picked up. but when someone says the SFI is 180 and thats good, why is that good exactly? and how does that translate to like, should i be sitting on 17 meters right now or not. also i saw someone post about a DX opening on 10 meters last tuesday and i had no idea it was happening until after the fact. is there somewhere people announce these things in real time or do you just have to be watching constantly? i feel like im always late to the party on this stuff. been trying to work some DX but my best so far is canada and thats barely counts haha

not required by the FCC or anything, its just a convention that most operators use because those specific words were chosen to be distinct from each other even with bad audio or interference. like november and november both start the same but the point is they dont sound like other letters when you're copying through static. that said you'll hear plenty of old timers who use their own phonetics out of habit and nobody really cares on a local repeater. on HF especially contest ops sometimes use non-standard ones that just punch through better, heard guys say lima as london or something like that. just learn the standard ones first so you dont confuse people, then do whatever once you get a feel for whats working

so i finally did my first activation last weekend, took about 2 hours to hike up W4T/SU-017 with a 10lb pack and i thought i was prepared but wow there were things i just did not account for at all. wind was insane up there, kept knocking my linked dipole around and i spent probably 20 minutes just trying to get the thing to stay put before i made a single contact. i had my kx2 and a 5ah lipo and in theory should have been more than enough power and battery but the wind was eating up so much of my time that i only ended up with 6 contacts before i had to pack up and head down before dark. technically i got the 4 contacts needed to activate so it counts, and i did log it on SOTAwatch already, but i just feel like there was so much i did a poor job with. especially the antenna situation. i was trying to set up an inverted vee off a 20ft mast and it just kept tilting over in the wind. do people use guy wires or something? also i spotted myself via the app before the hike and still had chasers waiting when i got up there which was cool but i also panicked a bit because i felt pressure to go fast and made some logging mistakes i had to fix later. anyway if anyone has done a bunch of activations and has advice on antennas in wind or just general tips for being more efficient up there i would really appreciate hearing it. im hooked on SOTA despite the rough start, planning to try again next month on a different summit in the same range

so ive been licensed for about 8 months now and i keep hearing people talk about CQ WW and Field Day and honestly it sounds like a lot of fun but also really overwhelming. like i dont even know what the difference is between them or which one would be better for a newer person to try first. i know Field Day is coming up in june and from what i understand its more of a club thing? my local club does it every year out at the fairgrounds but i wasnt sure if i should just show up or if theres something i need to do beforehand. i also saw some stuff about SOTA on here and that seems like a totally different animal, like hiking to a summit and operating portable which sounds amazing but also like a lot of gear to figure out. anyway im not really asking anything specific i guess, just wondering if anyone has thoughts on which of these events is good for a first timer and whether i should be worrying about logging software or if i can just do paper logs to start. my setup is pretty basic, just a 100w HF rig and a wire antenna in the backyard.

yeah the wall wart is probably your problem tbh. i gave up on them for any audio work, just run everything off a 12v gel cell now and the difference is pretty dramatic. you could also try one of those 78xx regulators after the wall wart if you dont want to deal with a battery, at least you'd know if thats the source of the hum before going further.

you're not overthinking it but also at 30 feet on 40m you're not going to have a dramatically great antenna no matter what you pick, so honestly just pick one and live with it for a while. that said if noise is actually your concern the dipole is probably going to serve you better, the directional null really does help in practice, not just theory. i had a nasty noise source almost due west of me and rotating my doublet to null it out made a genuine difference. obivously you cant rotate a fixed dipole but you can orient it so the ends point toward your worst noise sources and get some rejection that way. the vertical with radials will likely give you a lower takeoff angle which is better for DX but you said youre not really chasing DX hard so that probably doesnt matter much. also laying a decent radial field is more work than people expect. 16 radials minimum if you want it to actually perform, 32 is better. if the ground in your yard is anything like mine (clay with rocks) it's a whole afternoon of work.

As a new Tech, you have full privileges on VHF/UHF bands but limited HF access. For example, on 60 meters you must transmit exactly on the channel center frequency, which means setting your carrier 1.5 kHz lower. The key is understanding that FCC Part 97 sets the legal boundaries, while band plans organize activities within those boundaries for minimum interference.

the drift is almost certainly noise on the analog pin, i had the exact same issue with a pot-based position sensor on mine. try averaging like 10-20 reads in software and throwing out the outliers before you do anything with the value. made a huge difference for me. also depending on how long your wire runs are from the sensor to the arduino you might be picking up interference from the motor itself, shielded cable helped me there. on the pi to arduino comm thing i'd just go serial over USB honestly, i2c is fine but its fussier to get right and you dont really need the speed for rotator control. pyserial on the pi side is dead simple and you can have them talking in like an hour. i ran something similar for a while before i just moved everything to the pi with a motor hat and cut the arduino out entirely, but either way works.

so ive been meaning to do this for like two years and after the storms last month kind of kicked me into gear (no pun intended). got myself a Pelican 1510 case and started throwing stuff in. right now i have my FT-817ND, a LiFePO4 battery around 20ah, some coax, my j-pole rolled up, a few adapters and a notebook with my frequencies written down. also tossed in a headlamp which feels dumb but i figure why not. im pretty happy with where its at but theres gotta be stuff i havent thought of. like i keep reading about people having all these elaborate setups and mine feels kinda bare bones. is there a list somewhere or should i just think through scenarios? the main thing i'd be using it for is ARES activations or honestly just if the grid goes down and i want to stay on the air. any advice welcome, this community has always been super helpful when i have dumb questions

so ive got this arrow 146/437 yagi that ive been using for satellites and the 2m side is fine but the uhf is showing like 3:1 swr. checked all the connections twice and theyre solid. anyone else run into this with these antennas? starting to think maybe i damaged something during assembly but it looked pretty straightforward using a diamond swr meter if that matters. both sides were working fine when i first put it together last month

I've been running RTTY AFSK successfully with my IC-7300 using Ham Radio Deluxe/DM780, but I can't get FSK working properly. When I switch to RTTY FSK mode, I get solid carrier but no FSK modulation - just a continuous tone. I'm using both USB and CI-V cables as recommended online, with USB on COM3 and FTDI on COM4. The rig switches to TX but there's no warble or shift. Has anyone successfully configured FSK with the 7300? I'm wondering if there's a menu setting I'm missing or if this is a common DM780 timing issue. PSK31 AFSK works perfectly on the same setup.

im probably not the most qualified to compare them since i only really started logging seriously last year but i tried Log4OM first because someone on reddit recommended it and i found the setup kind of overwhelming at first. lots of options and i wasnt sure which database settings mattered. eventually got it working with WSJT-X and it does work well for that. havent tried N1MM yet because i havent done a real contest but i keep hearing i should try one at some point

8 contacts definitely qualifies you, you only need 4 so you had plenty of cushion there. the wind thing is real, ive lost paper logs off cliffs before so now i just use a small clipboard with a binder clip. also for the stakes thing i keep a couple of those orange plastic tent stakes rubber banded to my mast bag, saved me so many times the kx2 is a great choice for sota btw, mines been up probably 40 summits now and never had a problem with it. next time try 20m too if conditions are decent, sometimes you can snag some chasers in europe in the mornings which is a nice surprise

so ive been messing with APRS for a few weeks now and i cant figure out why my packets arent getting digipeated. im running a TM-D710G with the internal TNC, path set to WIDE1-1,WIDE2-1 which should be pretty standard. i can hear other stations getting picked up on 144.390 no problem, and i see my own packets on the radio display so i know its transmitting something. but when i check aprs.fi nothing shows up, or sometimes it shows up once every like 45 minutes which makes no sense. i did notice the squelch might be opening on noise occasionally but i dont think thats the issue. my antenna is a decent mag mount on the roof of the car, nothing fancy but it worked fine for regular 2m stuff. is there a known issue with the D710 TNC timing or something? ive read conflicting things about the audio levels needing adjustment but i cant find where that setting even is on this radio. also worth mentioning i moved to a new area last month and there arent as many digipeaters here as my old QTH, could that just be it? feels like there should be at least one close enough to hit though.
