so we've got a county ARES exercise coming up in about three weeks and i've been tasked with setting up the primary HF station at the EOC staging area which is basically a parking lot with nothing but a 120v outlet that may or may not actually work. last exercise that outlet was dead for the first two hours so im trying to figure out a backup plan that doesnt involve me running back to my truck every 20 minutes right now im thinking either bring my honda eu2200i and just run everything off that, or go with a lifepo4 battery bank situation. the radio is an ic-7300 so figure 20-25 amps peak on transmit, mostly doing winlink and some voice on 40/80. probably 6-8 hours of operation with maybe 30% duty cycle on tx. i also need to power a laptop and a little fan cause this is july and it will be miserable the generator option is obvious in terms of capacity but its loud and i hate dealing with the fuel and the 2200i isnt that quiet once it gets under load. the battery route is cleaner but im not sure a single 100ah lifepo4 gets me through the whole day comfortably with the laptop drawing too. was thinking maybe two batteries and a solar panel but finding a good mounting solution for the panel in a random parking lot is always kind of a pain also separately - what are people doing for portable HF antennas in a situation where you cant put anything in the ground and have maybe 30 feet of horizontal space. was gonna bring my buddipole but honestly ive had mixed results with it on 40 and below

I just passed mine about three months ago so I was basically in your exact situation not that long ago. I used the Ham Radio Prep app which costs a few bucks but I thought it was worth it, the explanations are pretty clear and it gamifies it a bit which kept me from getting bored. took me maybe 3 weeks of casual studying, probably an hour a night but not every night. the electronics questions look scarier than they are, once you see them a few times you just kind of memorize the answers even if you dont fully get the concept behind them. thats fine, you pick that up later when you actually start using the radio. good luck with it

so the tech exam really isnt that bad, i was stressing about it way more than i needed to. HamStudy.org is what i used, just ran through the question pool every day for like two weeks and i was getting 90%+ before i even went in. the actual question pool is public knowledge so youre literally studying the exact questions that could show up on the test, they just get shuffled around and some wrong answers swapped. for finding a test session you want to look up your local ARRL affiliated club, most of them run VE sessions pretty regularly. some places do walk-ins but most want you to register ahead of time so just email or check their website. bring a valid ID and like 15 bucks cash usually. the hardest part for most people is the electrical theory questions but honestly even those arent too deep at the tech level.

yeah im kind of in the same boat as you, been lurking on the EME reflectors for a while now. from what ive gathered the minimum people usually talk about for a realistic shot at digital EME on 2m is something like a single long yagi, 7 or 9 elements at minimum, and at least 100 watts at the feedpoint — meaning after your line loss. so if youre losing 2-3db in that coax run you need to account for that in your amp sizing the azimuth/elevation rotor situation is something nobody warned me about until i started asking around. you need to be able to track the moon obviously and if your current setup is just a az rotor for HF antennas that might not cut it. theres some guys doing it with creative fixed elevation setups and just waiting for the moon to pass through their window but thats pretty limiting i havent made my first contact yet so take all this with a grain of salt lol but thats what ive been reading on the moon-net mailing list

that consistent offset thing is usually a datum issue or sometimes a display glitch in how aprs.fi renders the coords. the D710G internal GPS should be outputting WGS84 which is what everything expects, but worth double checking your GPS settings in the radio menu — there's a geodetic datum setting buried in there somewhere and if it somehow got set to something other than WGS84 that would explain a fixed directional error like you're describing. also just to rule out the obvious — are you sure the lat/lon in your beacon is formatted correctly? the APRS position format is picky about degree/minute encoding and ive seen radios that had slightly wrong configs spit out coords that look right on the display but are subtly wrong when decoded. you can check the raw packets on aprs.fi by clicking the raw data tab and manually decode a position to verify. if the raw coords match where you actually are then its a display issue, if they're off then its coming from the radio config.

so our ARES group has a county-wide exercise coming up and i've been tasked with setting up the primary HF station at the EOC staging area. we're going out to a park about 2 miles from the actual EOC and running a field comms node, basically just a liaison station on 40 and 80m for traffic handling plus some VHF for local nets. my question is mostly about power. ive been going back and forth on whether to bring the honda eu2200i or just run off a big battery bank. the rig is an IC-7300 which at full 100w is drawing maybe 20 amps, and we could be running 6-8 hours with maybe 30-40% actual transmit time so not continuous key-down or anything. i've done the math and a 100ah lifepo4 should cover it but my elmer keeps insisting we should have the generator as backup at minimum. for the antenna i'm leaning toward the chaparral... wait no, the end-fed halfwave on a 31 foot jackite pole, thrown up as a sloper toward roughly northeast since thats where most of our check-ins will be coming from. last time i tried to put up a dipole at a park it took forever and the trees werent cooperating. anyone done something similar and have opinions on the generator question? also wondering if the sloper orientation even matters that much at typical NVIS distances, probably talking 50-200 miles here

so ive been licensed about 3 months now (technician) and I keep hearing about these nets on my local repeater but every time I think about checking in I freeze up and just listen. I know its probably simple but I genuinely dont know what the protocol is. like do I just say my callsign when the net control asks? do i have to say my name and location every time? and is there some kind of list I should be on beforehand or do you just jump in? also someone at my club mentioned there was a special event station operating near me this weekend for some kind of historical thing but I have no idea how to find out about those in advance. is there a website or something that lists them? sorry if these are dumb questions, just trying to not sound like an idiot on the air

The RMS gateway showing active on the map just means it sent a beacon recently, doesnt necessarily mean its in a good state or that the sysop hasnt had issues. First thing id check is your audio levels in Vara FM — the transmit drive is really fussy and if you're overdiving it the gateway will just ignore the connect request. In Vara there's a little ALC meter and you really want to stay out of the red, like aim for maybe 50-60% on the drive slider and see if that changes anything. Also double check that your PTT is actually keying the radio. With the Signalink it should be handling that via VOX but ive seen setups where the delay is off and the radio doesnt key fast enough before Vara starts sending data. There's a TX delay setting somewhere in Vara FM settings, bumping that up a tiny bit sometimes fixes it. What baud rate are you trying? Some gateways in my area only do 1200 even though the default in Vara wants to negotiate higher.

yeah the spots aging thing is totally normal and honestly its one of the more frustrating parts of starting out with clusters. most of those spots are only good for maybe a few minutes depending on how pileup-happy the DX station is. DXwatch and DX Summit are both pulling from the same underlying cluster network more or less — the Reverse Beacon Network feeds into a lot of it too if the station is CW or digital. so you're not really missing anything by not having both open at once, i usually just pick one and stick with it. the QRZ spot feed is fine but i find it a little cluttered personally. what helped me a lot was filtering by band so i wasnt staring at spots on 10m when my antenna is basically useless up there right now. hamspots app is decent from what i remember, though i havent used it in a year or so — does the job if you want something quick on your phone without opening a browser.

So ive been seeing WWFF pop up more and more on the clusters and finally looked into it properly last week. Looks really cool, operating from nature reserves and parks and logging contacts in protected areas. I activated a POTA site last year so im sort of familiar with the general idea of portable operating but WWFF seems a bit different and I cant quite figure out the workflow. Like do I need to register the activation beforehand or can I just show up, operate, and then upload the log after? I know with POTA you can do a self-spot and it shows up on the hunters app pretty much instantly but does WWFF have something similar? Also how many contacts do I need for it to count as a valid activation, I thought I saw 44 somewhere but wasnt sure if that was for all references or just certain ones. Im planning to go out to a WFF reference thats maybe 20 mins from my house, its a state wildlife management area and I already confirmed its in the database. Probably gonna run my KX2 with a random wire up in a tree, should be fine for 40m at least. Just want to make sure I dont mess up the logging side of it because that seems like the part that trips people up.

had almost the exact same symptoms on mine a couple years back. turned out to be Q1024 on the PA board, one of the driver transistors. the finals were actually fine. the tricky part is the reduced drive makes it look like a final problem but if all bands are affected equally and the ALC is behaving normally, the driver stage is the first place i'd go. you can check bias voltage on the driver stage before you even pull the finals, saves a lot of headaches. there's a service manual floating around on the Yaesu yahoo group archive or miklor's site has some of the board layouts. the bias trimmer for the driver is worth checking too, they can drift over time especially if the rig ran hot for a while. what's your heatsink situation like, does the fan kick on normally?

so i just passed my general a few weeks ago and got assigned one of those sequential calls, which is fine but its kind of long and clunky to say on the air. i started looking into the vanity callsign process and honestly the FCC ULS stuff is a bit overwhelming to read through. from what i can tell you basically just apply for whatever call you want thats available and then there's like a filing window and then... they pick randomly if multiple people apply for the same one? or is it first come first served? ive seen conflicting stuff online and cant figure out which is actually true. also does it cost money now? i heard they started charging a fee not too long ago but dont know if that applies to vanity apps too or just new licenses. any help appreciated, been going back and forth on whether its worth bothering with

so ive been doing a lot of hilltop activations lately, mostly 2m and 70cm, and im trying to decide if lugging a yagi up there is actually worth it over just using my diamond X50 on a painters pole. the X50 is dead simple and works fine for local repeaters but when im trying to work simplex or hit distant stations during contests or just good tropo conditions it obviously falls short the thing is i built a cheap 5 element yagi for 2m a while back from a design i found online and it works but its kind of a pain to aim and i feel like half the time im just guessing which direction to point it especially if i dont have a buddy on the other end telling me signal strength. also transporting it without bending anything is annoying has anyone gone the route of like a small moxon or a 3 element yagi that folds down or something that hits a decent compromise? or do you all just bring the collinear and call it good unless youre specifically doing EME prep or whatever. genuinely curious what people are actually using out in the field vs what they say they use

yeah what he said. i remember my first one i showed up way overpacked and stood around for like two hours before anything happened lol. the waiting is real. your EC should have a briefing at the start that explains assignments so just pay attention to that and ask questions if something isnt clear, nobody expects you to already know everything thats kind of the whole point of the exercise. the main thing is just showing up, a lot of people sign up for ARES and then disappear when an actual activation comes around so the fact that youre going counts for a lot.

so ive been using an RTL-SDR v3 with an upconverter for HF stuff for about a year now and honestly its been pretty decent for what it is. but ive been eyeing the SDRplay RSP1B and wondering if the jump in performance is actually noticeable in day to day use or if im just GASing out and should put that money toward a better antenna instead. main thing i care about is being able to actually dig stuff out on 40m and 80m at night when the bands are busy and the noise floor gets ugly. the RTL-SDR with direct sampling mode is fine but i can tell it gets a bit wobbly when theres strong signals nearby, had a local AM broadcast station wiping out a chunk of the band the other night which was annoying. heard the RSP1B has better filtering and a proper 14 bit ADC which should help with that but i honestly dont fully understand how much of a real world difference 8 bit vs 14 bit actually makes in a crowded band situation. running SDR++ on a slightly older laptop, nothing special. would the RSP1B even be usable or would it choke the CPU? anyone actually switched from RTL-SDR to SDRplay and have opinions either way?
