  1. so ive been running a diamond x50a on the roof for about two years now and lately ive been noticing that my signal reports from the local repeater guys are down maybe 2-3 S units from what they used to be. nothing changed as far as i know, same radio (ft-7900), same coax run which is about 35 feet of LMR-400 going from the shack up through the wall and out to the mast. i re-terminated the PL-259 on the radio end last fall because the old one looked a bit corroded but i just used the same basic silver solder and a random connector from the parts bin. my gut says its probably the coax connection at the antenna itself since i never touched that one and it's been up there through a couple winters. the antenna looks fine visually but i know that doesnt mean much. is it worth pulling the whole thing down to check or should i rule out other stuff first? also wondering if maybe the x50a just has a lifespan and mine is getting tired. these things dont last forever right
  2. im literally in the same boat as you right now lol. started using that LCWO site about six weeks ago and its actually going better than i expected. im on like character 15 of the Koch sequence now which still surprises me. one thing that helped me was just not skipping days even if its only 10 minutes, consistency seems way more important than how long each session is. also dont get discouraged when you plateau because i hit a wall around week 3 and almost quit but pushed through and it clicked after a few more days. good luck with it
  3. RemoteHams has been rock solid for me for basic rig control but i never bothered with the SDR panadapter over the same connection, always seemed like overkill for casual operating. if youre mostly doing HF work the 7300s built in waterfall over the CAT interface is probably good enough anyway. the latency thing on DSL is usually more about jitter than raw bandwidth in my experience, ran into the same headache on a vacation rental setup once and switching the audio codec from PCM to something like Opus made a noticable difference. worth poking around in the RCForb settings if you havent already.
  4. totally get the confusion, i was in the same spot when i first got licensed. here's the short version of how i think about it: LoTW is basically the gold standard if youre chasing awards like DXCC because the ARRL only accepts LoTW or physical cards for that. eQSL is kind of its own thing and a lot of people use it but its not accepted for DXCC. paper cards are the old school way and honestly still fun to get in the mail, some people really love the physical ones. for FT8 specifically, a lot of logging software like WSJT-X can upload directly to LoTW automatically which is really handy. you do have to go through a bit of a setup process to get your LoTW account working — you need to request a certificate and it takes a few days to get sorted. eQSL is way easier to set up immediately if you just want something working fast. as for QSL managers, yeah that's basically someone who handles QSL requests on behalf of a DX station, usually because the DX op is in some remote location or just doesnt want to deal with all the mail themselves. you'd send your card or request to the manager's address instead. most of the time managers only deal with paper cards but some also handle LoTW uploads for the expedition.
  5. so we finally got our ARES group together for a full day tabletop plus actual radio exercise last saturday and honestly i learned more in those 8 hours than i had in months of just reading about emergency comms. figured id share some stuff that surprised me or caught us off guard in case anyone else is planning something similar. the biggest thing that hit me was how fast message traffic gets backed up when you only have two operators handling net control and the simulated 'served agency' keeps changing their mind about what they need. we were running Winlink for formal traffic and voice on the local 2m repeater as backup and at one point the repeater went down (on purpose, they didnt tell us ahead of time) and like half the group just... froze. nobody had confirmed their simplex fallback frequencies before the drill started. that was embarrassing but also really good to find out now and not during an actual event. also found out one of our members had a go-bag that hadnt been touched in two years and his HT battery was completely dead. again, better now than during a real deployment. the whole thing was kind of humbling but in a good way. curious if anyone else has done these kinds of exercises and what caught you off guard
  6. had almost the exact same problem last year, turned out my firewall was blocking VARA from reaching out on the ports it needs for the telnet fallback. winlink tries a few different connection paths and if something is blocked it just silently fails and looks like a radio timeout. worth checking if you have any security software that might be interfering, even windows defender sometimes does weird stuff with new software.
  7. went through basically this exact decision about two years ago. ended up with the RSP1A and honestly for pure receive quality it was a pretty noticeable jump from the v3 dongle, especially on HF. the noise floor is better and the dynamic range makes a real difference when you're trying to pull weak signals out near a strong broadcast station or whatever. SDRuno is a bit clunky to learn but once you figure it out it works fine, or you can just use it with SDR# if you dont want to bother. the HackRF is a different kind of device though. its got 20MHz bandwidth which is great for certain things but its a pretty mediocre receiver compared to the RSP1A at the same price. the transmit thing sounds cool but if you already have a licensed radio setup you probably wont use it as much as you think. if your main goal is better receive performance id go RSP1A without much hesitation.
  8. repeaterbook is what everyone uses, seconding that. also some repeater clubs have their own website with all the info, worth googling the call sign of the repeater trustee if you can find it from the FCC database. one thing i'd add — if you're not sure if you're actually hitting the repeater, try this: key up, say your callsign, then just listen for the courtesy beep or tail. if you hear the repeater's squelch tail or a beep after you unkey, you got in. if you get nothing you either dont have the tone right or youre just not making it in from where you are. happened to me for like two days when i first started, turned out i had the offset backwards lol.
  9. so ive been a general for about two years now and i keep going back and forth on whether to bother with the extra. like i know you get the extra spectrum privileges and all that but honestly i dont use half of what i have access to now. the main thing holding me back is the theory sections — the stuff about phase angles and filter design and whatever the smith chart questions are about. i passed my general without really understanding all of it and im worried extra is gonna be a whole other level of that. does anyone actually use the advanced theory stuff in day to day operating or is it mostly just to say you passed the hardest test. genuinely asking because i dont want to spend three months studying for something that doesnt change how i operate at all. though i guess the cw sub-bands thing is appealing if i ever get serious about morse.
  10. oh man yes, happens to me every winter. i get super into it around october when the bands start acting up again and then by february im barely touching the radio. i think its pretty normal honestly. the hobby will wait for you, thats kind of the nice thing about it
  11. so ive been a Tech for about 2 years now and mostly been doing VHF/UHF stuff, some APRS, got my first HT and then a mobile rig, the usual path i guess. but lately ive been really curious about HF and everyone keeps telling me to just get my General and i keep putting it off because honestly the exam just looks intimidating compared to the Tech one. like i looked at the question pool and there's a lot of stuff about propagation and electrical theory that i dont really understand. i passed my Tech by mostly memorizing answers with HamStudy which worked fine but im not sure if that approach works as well for General or if the questions are harder in a way that trips you up more. also someone at my local club said something about needing to know math for the General which kind of scared me off for a bit. anyway i guess my main question is, is it actually worth the time investment and how long did it take you guys to feel ready for the test. and also once you have General what are the HF privileges like, can you actually get on 40m and work DX or is it still pretty limited until you get your Extra
  12. the honest answer is yes and no. the question pool memorization approach will absolutely get you through it, thats just a fact, but some of the calculation questions are tricky because they reword the same concept a few different ways and if you dont have at least a gut feel for what youre doing with like LC circuits or the smith chart stuff you might mix yourself up. i spent about 6 weeks going through the ARRL extra class book and i actually found myself genuinely interested in some of it, the stuff on propagation modes and the emission type breakdowns was stuff i never really thought about before. as for whether it changes your operating — honestly for casual HF work the extra khz thing is a little overhyped but during contests and when bands are crowded it does matter. the 160m and 60m allocations specifically were things i started using more after i upgraded. and theres something psychological about it too, i dont know, you just feel like you understand whats happening a little better when you actually worked through the theory even partially.
  13. dont sleep on just trying a ham-it-up upconverter with your existing rtl-sdr before you spend the money tbh. got me through like another 6 months before i finally caved and got a proper SDR. depends how patient you are i guess. that said once i did move to an RSP1A i was kind of annoyed i waited so long lol, the difference on 40m at night especially was pretty obvious
  14. So ive been messing around with Winlink for about three weeks now and i think i finally understand the basic concept but im still fuzzy on a few things. Running a KX3 into a SignaLink USB and using Winlink Express on a windows 10 laptop. Got my first message through last week via a nearby VHF RMS gateway on 2m which was pretty exciting honestly. My question is more about the gateway side of things. Right now im just connecting to whatever shows up in the frequency list that has decent signal. But i've heard people say you should try HF gateways for anything serious, like actual emcomm use or if the local repeater infrastructure goes down. Tried a couple of the HF ones on 40m with PACTOR but my interface only does VARA HF which apparently is fine? Someone at the club said VARA is basically PACTOR-lite and not all gateways support it. Is that still true or has VARA gotten more widespread. Also — and this is the part that really confuses me — what exactly is a Winlink hybrid network node vs a regular RMS gateway. the documentation is kind of dense and i keep losing track of what connects to what. Do I need to worry about this as an end user or is that more of a gateway operator concern. Thinking long term i might want to run my own RMS relay someday but not sure if thats even worth it given how many are already up.
  15. yeah 40 has been my go-to lately too, usually got it on while im cooking dinner or whatever. heard a couple guys from Tennessee last night going on about antenna stuff for like an hour, didnt mind though it was good background noise lol. the band was surprisingly quiet for a weeknight
  16. Welcome to the addiction, seriously once you do your first one you wont want to stop. Ok so to answer your questions - you dont need to pre-register anything, just show up, make your contacts, then log them on the SOTA database afterward. The summit reference for W6/NC-461 should already be in the system. Self-spotting via SOTAwatch3 once you're up there is the way to go, chasers watch that thing like hawks and youll get a pile up pretty fast especially on a weekend morning. If for some reason you lose cell service you can always try calling CQ on 14.285 or 7.285 and someone will usually spot you. Also worth posting an alert on SOTAwatch before you leave home if you can, even a rough time estimate helps chasers plan their day. The 4 contact minimum is hard - no partial credit unfortunately. But honestly on 40m SSB on a Saturday morning you should have 4 contacts within the first 5 minutes of calling, no problem. Have fun and post how it goes.
  17. oh man i had the exact same problem when i first started, sat there for like two weeks wondering why nobody ever heard me on the local machine. turned out i had the tone set but on the wrong memory channel because i had programmed it twice by accident. double check that the tone is actually saved to the right channel in your radio, the Baofeng menus can be a little funky about that.
  18. I went through the same debate last year, was looking at the 7300 vs holding out for a used 7610 at a reasonable price. Ended up with the 7300 and honestly for what I do — mostly ragchewing on 75m and some CW on 40 — it's way more radio than I need in the best possible way. The dual watch function took me a while to get my head around but once it clicked it's super useful. Your point about the menu depth is real. I was like six months in before I found the adjustments for the AGC decay timing and that made a pretty big difference for CW. Not criticizing the radio at all just saying dont assume youve found everything even after you think you have.
  19. ok so ive been checking into my local 2m net every tuesday for like a year now and i still feel like im guessing half the time when it comes to the right moment to say something or ask a question during the net. like the net control will say "any further traffic or comments" and sometimes i want to say something but i freeze up because i dont know if thats actually the right window or if im supposed to have already said something earlier when he asked for check-ins. also whats the deal with breaking in between stations when theres an ongoing conversation on a simplex frequency? i know you say your callsign but how long do you wait before trying again if nobody responds? i feel like ive been way too timid about this stuff and its probably holding me back. my elmer passed away last spring and i dont really have anyone local to ask anymore so figured id just post here.
  20. so ive been chasing 3Y0 for a while now and just generally been frustrated with pileups because i feel like i do everything right and still get nowhere. last week there was a fairly rare pacific entity active and i finally broke through after like 45 minutes of trying and i want to share what ended up working because it wasnt what i expected. first thing i changed was stop transmitting when everyone else was. i noticed the DX station had a rhythm — he'd come back to someone, there'd be this half second gap while the pileup all fired at once, then he'd go again. so i started timing my calls to land just slightly after the initial wall of signals. not by much, maybe half a second. seemed counterintuitive but i think it let my signal sit in a slightly less cluttered moment. also switched from calling my full callsign to just the suffix for a while. i know some people say that's bad practice but honestly on SSB when you're in a wall of noise i think just punching the suffix in clean is more effective than trying to get your whole call through. the DX was clearly already in split and working the pileup fast so he just needed to grab something unique. i run about 500w into a 3-ele yagi at 45ft, nothing crazy. i dont think power was the issue. what do you guys actually do differently when you're trying to break a really nasty pileup, especially on SSB? CW is a different animal i know but curious about both.
  21. that intermittent-on-one-band behavior is suspicious for a band switching relay issue. the 7300 routes different bands through different relays for the BPF stages and if one of those relays has a dirty or worn contact it'll do exactly what you're describing — works fine when the contact happens to seat right, then degrades when it shifts a little or heats up. the thermal aspect you mentioned, coming back after 20-30 min, could be the relay contact expanding slightly which either makes or breaks whatever marginal connection is there depending on which direction its failing. not a trivial fix to do yourself since you'd have to get into the RF board but if you're comfortable with SMD work it's worth pulling the top cover and looking for the BPF relay bank. some guys have had luck just reflowing the solder joints on those relays. there's a service manual floating around if you search for it, has the relay locations marked. if you're not comfortable going in there honestly icom's service isn't that expensive and they'll find it fast since they see this stuff all the time.
  22. the preamp question is actually more important than most people realize when theyre starting out. you can have a huge antenna and completely blow your system noise figure with a mediocre preamp or even decent coax running 20 feet before your first stage of amplification. get the preamp at the feed, full stop. a good low noise amp like the ones SSB Electronics used to make or the current offerings from Kuhne are worth every penny. you want your NF down around 0.3-0.5 dB range ideally and that only happens if its physically right at the antenna. on the antenna side yeah single yagi EME is a thing now with JT65B and Q65 but youre going to be limited to working the big guns — stations running kilowatts into large dishes. which is fine honestly, you still make the contact. but if you want to work smaller stations too you need more antenna. i started with 4x17 element yagis on 2m and that felt like a reasonable entry point. could work maybe 60-70% of active EME stations on a good night. added two more yagis later and it made a noticeable difference. also check out the WSJT-X documentation and specifically look at Q65 which has kind of taken over from JT65 for EME in the last few years. the sensitivity improvement is real.
  23. Great points about pronunciation! "Lima" should be "LEE-ma" not "Lee-mah" - mispronunciation creates confusion in noisy environments. I always demonstrate common mistakes during training sessions so new hams know what to avoid.
  24. nice work. i built my first dipole about a month ago for 20m and it was kind of a revelation honestly. i way overthought it before i started. mine's just hung between two trees with some paracord and it works better than anything i was using before. the commercial HF antennas in my price range were all compromised in some way anyway so the homebrew route made sense.
  25. I remember that feeling! What helped me was practicing my introduction out loud before keying up. Just say your call sign clearly, mention you're new, and ask for any station. The ham community is really friendly - someone will definitely come back to you. Welcome to the hobby!
