ran a disaster sim last weekend, some things went really wrong (in a good way?)
so our ARES group finally did a full scale exercise last saturday, simulated a major flooding event cutting off three counties from normal comms infrastructure. we had about 14 operators spread across different served agencies and honestly i went in thinking it would go pretty smoothly because we do tabletops all the time. nope. first thing that fell apart was check-in procedures. net control was getting slammed with traffic from multiple stations at once because nobody had really internalized the proper order of operations when multiple priority messages come in simultaneously. it got chaotic fast and we basically had to pause and regroup after maybe 20 minutes. second thing - and this is the one that really humbled me - two of our newer operators froze up when asked to handle formal traffic. they know winlink fine, they know how to operate their radios, but when a served agency rep handed them an actual message form and said get this out, there was just this deer in headlights moment. we dont practice that part enough, the handoff from agency to operator, thats where things got wobbly. the stuff that went well was actually the simplex fallback plan. when we pretended the main repeater was down, guys shifted to simplex without much fuss which was great to see. anyway curious if anyone else has run exercises like this and what your biggest lessons were, especially around training newer ops before the real thing

struggling with my first paddle, hand keeps tensing up
I went through almost the exact same thing last year. What helped me more than anything was just shortening my practice sessions -- like 10 minutes, take a break, come back. Your hand literally learns better that way apparently, something about muscle memory consolidation. Also I switched to a single lever for a while because I was confusing myself with iambic mode on the dual lever. Might not be for everyone but it simplified things for me while I was getting the basics down.

Icom released something new? plus some band news from this week
yeah 10m has been treating me really well too, worked into europe a couple times this week which honestly surprised me because my antenna situation isnt great right now, just a dipole up about 25 feet. Solar flux has been staying up there and the K index cooperated for once. Makes me want to actually get my yagi sorted out before the cycle really peaks. On the Icom thing -- i think youre probably talking about some FCC filing or a trade show leak, they do that sometimes where stuff shows up on the website before theres any official announcement. Wouldnt get too excited until theres actual specs posted somewhere reliable. That said i am genuinely curious what they come up with. The 7300 is hard to beat at its price point and it feels like theyve been sitting on updating it for a while now.

SSB audio always sounds like garbage on my end apparently
the ALC thing is your main issue probably. on the 7300 you actually want the ALC moving a bit more than just barely — like you want it nudging into the first third of the bar during normal speech peaks. if its barely moving your mic gain is too low and the radio is basically transmitting at low power with no punch. what happens is guys on the other end are hearing you but you sound thin and they're cranking their RF gain to hear you which adds noise. on the TX EQ — dont leave it flat, that's leaving performance on the table. the stock hand mic that comes with icom gear has kind of a mediocre frequency response honestly. a lot of guys boost a little around 2-3kHz which is where speech intelligibility lives and cut below 200Hz to kill the boominess. you dont need to go crazy just a gentle curve. and yes holding the mic about an inch or two from your mouth matters, talking straight into the capsule versus at an angle makes an audible difference, not huge but its real.

starting to study for tech license, any tips on where to even begin
so i've been wanting to get into ham radio for a while now and finally decided to just go for it and take the technician exam. i downloaded the question pool pdf from the arrl website but honestly its like 400 pages and i dont even know what im looking at half the time. like some of the electrical theory questions are fine but then theres stuff about propagation and band plans and i have no idea how any of that connects to actually using a radio my cousin told me to just memorize the answers without really understanding them and i could probably pass that way but that feels kinda wrong? like i want to actually know what im doing when i get on the air. does anyone have a method that actually worked for them or a study guide thats not just a wall of text. ive been looking at ham study dot org and it seems okay but not sure if thats enough on its own

field comms setup for this weekend - generator vs battery question
the math on this really depends on your duty cycle more than anything. if youre doing heavy digital like JS8Call or Winlink relay you can burn through that 100ah faster than you think, especially if you're running anywhere near full power. my 7300 at 100w pulls something like 20 amps on transmit and maybe 2.5 at receive, so do the duty cycle math for however much you actually expect to be keying up. personally for an 8 hour event id just bring a second battery and forget the generator. two 100ah lifepo4s is still way lighter than that honda plus a gas can and you dont have to deal with the noise or the fumes or making sure someone remembers to check the oil. we did a 12 hour comms exercise last spring with two of those batteries and an FT-991A and came home with 40% left. granted we werent hammering it constantly but still. the truck alternator thing is fine in a pinch but yeah idling for hours is not great. if you go that route at least get a decent dc-dc charger like a Victron Orion so you're not just float charging through the aux port.

SO2R during contests — is it actually worth the headache?
the filtering is non-negotiable if your antennas are anywhere near each other. i ran without proper bandpass filters once and it was exactly what you described, just garbage. the 4O3A filters are the gold standard but the Dunestar 600 series works fine if you're on a budget, ive had mine for probably 8 years. you really want the two radio paths to be as isolated as possible at the antenna level too — separate feedlines, separate antenna systems if you can manage it, not just filters inline. as for the mental side of it, it honestly just takes reps. the first few contests youre going to fumble the timing constantly, miss exchanges because your ear is half on the wrong radio, all of that. what helped me was starting SO2R only during slow rate periods, like when running on 20 dries up at 0200 local, thats when you go hunting on 40 with radio 2 while radio 1 just holds the frequency. you're not trying to do both at full speed at first. build up from there. took me maybe 3 serious contest weekends before the rhythm started feeling natural.

finally did the TX mod on my 857D and some thoughts
the fan mod is honestly the best thing you can do for those radios if you run digital at all. i did something similar on my 897D except i used a PWM controller tied to a thermistor i stuck to the heatsink with some thermal epoxy. gives you a nice smooth ramp instead of just off/on. the stock fan on these yaesu rigs from that era is barely adequate even for SSB if you're doing any kind of contest operating, forget about sustained digital. on the recap question -- i wouldnt bother with the audio section unless youre actually hearing something wrong. those elna caps in there are generally fine. where recapping actually makes a difference on older 857s is the PA board if you've got one thats been sitting unused for years, some of those electrolytics get a bit leaky over time and you can see it in the power output starting to sag or get inconsistent. worth scoping the supply rails on the PA while you have it open if you havent already.

what do all these Q codes mean? people keep using them on air and i have no idea
so ive been licensed for about 3 months now and i mostly just listen on HF since im still nervous about transmitting. but i keep hearing people say things like QSL and QRZ and QTH and honestly there are so many of them i cant keep track. i tried looking them up but i found like 50 different ones and now im even more confused about which ones people actually use vs which ones are just technically in the book but nobody says anymore. also is there a difference between how people use them in voice vs CW because i feel like on SSB people sometimes use them kind of loosely? like someone said QRM to me and i wasnt 100% sure if they meant actual interference or just that they couldnt hear me well. anyway just wondering if someone can break down the ones that actually come up day to day

first POTA activation went better than expected, some notes from a total newbie
so i finally did my first parks on the air activation last weekend at a state park about 45 minutes from my house, K-2830 if anyone knows it, and honestly it went way better than i thought it would. i was super nervous about the whole thing because ive been licensed for about 8 months and mostly just do local repeater stuff and the occasional HF contact from home. i brought my IC-705 and a wire antenna i threw together from some stuff i had laying around, just a basic end fed half wave thing i hung between two trees with a piece of paracord and a slingshot. got it up maybe 25 feet at the high end which i know isnt ideal but whatever. set up on 40m SSB because thats what most of the youtube videos i watched said to start with and within maybe 10 minutes i had my first pile up which was honestly kind of overwhelming? i didnt realize hunters would spot me that fast once i got on pskreporter and threw my callsign into the POTA website. ended up with 32 contacts in about an hour and a half which i think is decent for a first time. one thing i wasnt prepared for was people calling on top of each other, im used to pretty polite repeater QSOs so the whole pile up management thing was new. any tips for next time? also does anyone know if you have to stay within the actual park boundary the whole time or can you set up just outside the entrance

finally did the TX mod on my 857D — worth it or did i waste a weekend
yeah i did basically the same fan swap on mine two years ago and it's been solid. also added a small heatsink to the PA transistors while i was in there, some guy on eham had a writeup on it. not sure it does that much but it made me feel better lol. one thing i'd suggest if you havent already — the audio mods. theres a pretty well documented mod to improve the rx audio filtering on the 857, involves swapping a couple caps in the audio chain. reception on weak SSB signals genuinely improved for me. not a huge deal if you're mostly doing digital but for voice it was noticeable enough that my wife who also has a ticket commented on it which i took as a good sign.

finally got my 857D mounted in the truck, few questions about the setup
so ive been putting this off for like 6 months but i finally got the FT-857D mounted in my F-150 last weekend. runs on VHF and UHF just fine so far, been hitting the local 2m repeater with no problem. i ran the power leads directly to the battery with an inline fuse which i was told is the right way to do it. my main question is about the antenna. right now im using a mag mount i had sitting around, its a dual band whip and its just sitting on the roof. works okay but i get some noise when the engine is running, not terrible but noticeable. i was wondering if a proper NMO mount would make a difference or if its more likely something else causing the interference. also the mag mount keeps sliding a tiny bit when i make turns which is kind of annoying. second question is kind of dumb but how are you guys routing your coax inside the cab? i ran mine through the door jamb which seems fine but i feel like im pinching the coax a little. is that a real concern or am i overthinking it

when do you actually call CQ vs just joining a net — confused about the difference
calling CQ and checking into nets are really pretty different things yeah. when you call CQ you're basically just putting yourself out there and hoping someone wants to ragchew or do a contact, totally freestyle. a net is more structured — there's a net control station running it, people check in, sometimes there's traffic (like formal messages being passed), sometimes its just a social check-in deal. you dont have to do either one, plenty of people just listen for years honestly. for 40m in the evenings you're right that it gets crowded fast. what i usually do is spend a few minutes on a frequency listening to make sure its actually clear before i transmit anything. the old saying is listen listen listen before you transmit and its genuinely good advice not just something they tell newbies. if you hear nothing for like 2-3 minutes and its a reasonable spot away from known net frequencies then a quick "is this frequency in use" is totally fine and then go for it. dont stress too much about messing up, everyone was new once and most folks on HF are pretty patient as long as you're making an effort.

SSB audio always sounds muddy on the other end, what am i doing wrong
yeah what he said about ALC is spot on. i spent like three months wondering why my audio sounded terrible and it was literally just the gain set too high. also one thing i do now is record myself with audacity through the USB audio on the 7300 — you can actually hear what youre transmitting that way without needing a second radio and it was kind of a revelation honestly. sounded way worse than i thought it did in my head lol. once i could actually hear the problem it was a lot easier to fix
-
ran my first ARES exercise last weekend — some things went better than others
this is the kind of stuff i wish i'd read before my first exercise honestly. i showed up to one about six months after getting my ticket thinking i basically just needed to know how to key up and say my callsign and uh... it was a lot more than that. nobody told me what ICS was or why the net control kept asking for message numbers. felt pretty lost for the first hour. does your group do any kind of orientation for new people before throwing them into a full exercise? or is it more just learn by doing

inverted V vs flat top dipole — does it actually matter that much?
so ive been running an inverted V for 40m for a couple years now, apex at about 35 feet off a push up mast, ends drooping down to maybe 8 feet off the ground on each side. works fine, i get out, no complaints really. but i keep reading that a flat top dipole is supposed to be better and i'm starting to wonder if i'm leaving performance on the table. the thing is my yard isnt huge and getting a flat top up at any decent height would mean either a really tall support in the middle or two supports at maybe 25-30 feet which i dont have. the inverted V at least lets me use one center mast. so is the radiation pattern difference actually noticeable in practice or is this more of a theoretical thing that doesnt matter much in real world conditions. i feel like on 40m especially the angle stuff gets complicated and im not sure the inverted V is as bad as some people make it sound. anyone actually compared the two back to back with the same feedline same location? or is this one of those things where the answer is always just get more height

confused about CTCSS tones on the local repeater — am i doing this wrong?
ok so ive been licensed for about 3 months now (technician) and i finally got my HT programmed for the local 2 meter repeater. my elmer helped me get the frequency and offset set up but the CTCSS tone thing is kind of confusing me still. so from what i understand, you program a tone so the repeater opens up and actually retransmits your signal, right? but someone at the club meeting said some repeaters also have a tone they send back out and you can set your radio to squelch on that too so you only hear traffic from that specific repeater. is that true? because i didnt realize there were two separate tone settings, i thought it was just one thing you had to enter. also kind of a separate question but related — whats the deal with etiquette on these things. like do i just key up and start talking or is there some protocol i should know about? i listened for a while and it seems like people just say their callsign and wait but i wasnt totally sure. dont want to be that guy who does it wrong on his first real transmission lol
- first POTA activation didn't go quite as planned but still a blast

FT-7900 keeps cutting out on the highway — antenna maybe?
So ive had this Yaesu FT-7900 mounted in my truck for about 8 months now and lately its been doing this weird thing where it just drops mid-transmission. Like im talking to a guy on the local 2m repeater and the audio just cuts for half a second and comes back. Sometimes it does it a few times in a row. Doesnt seem to happen when im parked but on the highway it gets bad, especially when i go over bumps or rough pavement. My setup is a NMO mount on the roof with a Diamond NR770H dual band whip. The coax run goes through the door jamb and under the center console to the radio. I torqued the NMO mount down good when i installed it but maybe the coax connection at the base is getting loose from vibration? I havent pulled the antenna off to check yet because its a pain to get to on my truck. Has anyone dealt with something like this before? My first thought is the PL-259 at the radio end or maybe the NMO connector itself is the culprit. Just wanted to ask before i tear everything apart this weekend.

just got my technician license last week, had my first real QSO yesterday
so i finally passed my tech exam on the 14th after studying for about 6 weeks and honestly i was terrified to key up on the local repeater. like i knew the theory but actually talking felt different. anyway yesterday i just did it, caught a guy calling CQ on 146.520 and we had maybe a 10 minute ragchew about nothing really, he asked about my radio (baofeng uv-5r, i know i know) and where i was located and that was kinda it but man it felt like a huge deal. my hands were literally shaking when i picked up the mic. anyone else remember their first contact being weirdly nerve wracking even though its just talking on the radio?

confused about CTCSS on the local repeater — am i doing something wrong?
yeah you just need the transmit tone set, not the receive side. the receive CTCSS (sometimes called tone squelch) just filters out what you hear on your end — it wont affect whether the repeater opens up for you. so go into the baofeng menu, find the T-CTCS option (not R-CTCS) and set that to 100.0 and you should be good. a lot of new folks set both and it still works fine but technically only the transmit matters for getting into the repeater. and yes the pause thing is real, not superstition at all. after the repeater drops its carrier there's usually a courtesy tone and then a short tail, and if you jump on too fast sometimes the repeater or the linking system doesnt have time to reset and your first word or two gets clipped. just wait for the beep and then a beat or two and youll be fine. it also gives anyone else a chance to break in if they need to, which is just good operating practice.
-
N1MM vs Log4OM for everyday logging + contest use, anyone run both?
honestly i just use N1MM for everything including daily logging and never really bothered with Log4OM. probably not the answer you want but it does work, the everyday logging mode isnt as bad as people make it out to be once you get used to it. though i will say the notes field situation is not great.
- anyone else just sitting on 40m tonight not really doing much

how do people actually learn morse code, like from nothing
so ive been licensed for about 8 months now (general) and i keep seeing people talk about cw and it sounds cool but i genuinely have no idea where to start. like i downloaded some app a while back and it just showed me a chart of all the letters and i tried to memorize them but that didnt really go anywhere. is that even the right way to do it or am i missing something obvious i dont have any pressure to learn it, no test or anything, just kind of curious if its actually worth putting time into and how long it realistically takes before you can do anything useful with it. most stuff i read online is either really vague or assumes you already know the basics
