oh man dont stress about it, everyone steps on someone at least once when theyre starting out, it literally happens to experienced ops too especially on busy nets. the timing thing just comes with ear training honestly. for most directed nets the way it works is net control will say something like "any additional check-ins" or pause after calling for check-ins, and thats your window. the trick is not jumping in the absolute first millisecond the frequency opens up — give it just a beat, maybe half a second, so you're not doubling with someone who started at the same time. if you do double with someone net control will usually just ask both to repeat and it's no big deal at all. and checking in with no traffic is completely normal and totally welcome. a lot of nets actually want to know how many active stations are out there even if nobody has anything to pass. you can just say your call and say "no traffic" or "listening" and youre done. some nets actually track participation numbers so your check-in matters even if you dont say a word after that.

yeah this trips up a lot of new generals, dont feel bad. the short answer is the arrl band plan is basically a gentlemens agreement, it has no legal standing. what actually matters legally is part 97 which defines your privileges by license class. for general on 40m phone you can operate from 7.175 to 7.300 MHz in the US, not 7.025 — that lower chunk is CW/data territory for generals. the 7.125 area you heard about is more of a DX window thing, its kind of informally reserved so US stations dont step on DX stations working into other regions where their allocations are different. again not legally binding but if you start calling CQ down there youll probably get some grumpy responses. as for band edges, the thing is your transmitted signal has a certain bandwidth. SSB is roughly 3 kHz wide, so if you set your dial to 7.175 youre actually putting energy below that. FCC looks at the whole signal not just your carrier frequency so you want to stay a bit inside the edge to make sure your whole signal is within your authorized segment. most people just stay a few kHz inside and dont sweat it too much but its worth understanding why.

the fan writeups on eham and some of the older groups.io archives should still have part numbers. i bookmarked one a while back but cant find it now, typical. what i do rememeber is someone used a Noctua NF-A4 which is obviously overkill but dead silent and supposedly fits with some bracket modifications. seemed like a lot of work to me but if you care about noise floor during receive it might matter.

so ive been a ham for about 8 months now, got my general last spring and ive been mostly doing stuff on 40m and some local repeater stuff. someone at my club mentioned ARES and said i should look into it but honestly the info on the websites is kind of all over the place depending on what county you look at. my main question is what actually happens at a real activation, like not a drill but an actual emergency. do they expect you to just show up and know what youre doing or is there training beforehand that walks you through it. i took the ICS-100 and 200 online courses because someone said you need those but i dont really know what comes next or if theres more i should be doing before i even show up to a meeting. also not sure if my setup is good enough — i have a baofeng and a mobile rig in the car, nothing fancy. would that even be useful or do they need people with bigger stations

yeah the hum being quieter on battery but not gone is a classic sign its not just the supply, something else is radiating into your circuit. i had almost the exact same problem with a regen i built last year, turned out my audio wiring was running parallel to the coil leads for like two inches and that was enough. moved the wires and it dropped like 15dB. worth just poking around physically and seeing if moving wires changes anything

internet linking and SDR remote are kinda two different rabbitholes honestly, i wouldnt mix them on the same planning if that makes sense. for the repeater linking you probably want to look at allstar or maybe IRLP depending on what the club already has going, SDR streaming is more of a personal shack thing. i run my remote with just the rig audio and skip the panadapter entirely when im mobile because the latency on the visual stuff annoys me more than helps 15mb upload should be fine for one rig connection, thats way more than needed for compressed audio. id suspect something else is going on, maybe QoS on your router isnt prioritizing the audio packets and the SDR stream just eats everything. throw the rig traffic on a higher priority queue and see if that cleans it up before you mess with anything else

80, 40, 20, and 15 meters have segments exclusively for Amateur Extra operators. 80, 20, and 15 meters have both phone and data segments reserved for Amateur Extra; 40 meters has only an additional data segment reserved for Amateur Extra. The frequency privileges haven't changed with the new question pool.
