Decoding on SDR is annoying because your soundcard seems to drift sometimes, I can't do WEFAX over SDR for that reason. (in a browser, yeah?)

yeup

got my hf rig receiving (not trying transmission with this setup yet) after being lazy with my license for almost a full year; just recording wwv this week (can't hear rwm well enough unfortunately) for this:

I posted these on the Discord but may as well share them here too. I did ISS SSTV for the first time today after previously doing some terrestrial QSOs with it. It came out so well for a first attempt and I can't believe I got images from space.

Antenna was the Slim Jim up the 4 metre pole, which I had assumed would be poo poo for this kind of work, especially with a 39 deg elevation pass. I had expected to need a beam of some kind. But no, extremely loud signal even given the extra distance and it was an incredibly easy copy. The sight of me jumping and punching the air in the park would have been amusing to onlookers, certainly.

I also brought my neighbour along for the fun who was not expecting it to be quite so good and was quite excited by the whole thing. Ace afternoon in the sunshine, best radio fun in ages.

super cool!

that's the radio trick that made me want to get a license in the first place years ago, so i should get on doing that myself after all this time, thanks for the reminder!

best I could do this time:



mad at myself as i should have adjusted the carrier down to account for the redshift that was clearly visible in the sdr waterfall and i could have gotten more of the frame; oh well, it was certainly fun trying

I have a friend who, along with some coworkers who definitely should have known better (because they weren't summer research interns), thought it was a good idea to play Keep Talking and Nobody Explodes over FRS walkie talkies at a controlled federal facility which is considered a vital security asset and has lethal force authorization and they found out pretty quickly that someone will indeed track you down and tell you that you have to stop.
:eng99:

Your game sounds fantastic, though, and I love that idea. If anyone wants to run something similar without having enough licensees around to do it via ham radio, Zello could probably recreate a similar experience since it's PTT by default but is done over the internet.

PSA: .radio domains are 25 euros a year if you're registering your callsign. There are a few other ways to get the ~90% discount, but this is the one I care about

You need to go through register.radio to get the discount - all the other registrars i checked like Gandi only sell for the full-price 200-something euros/year.

register.radio makes you fill in your contact info for the various WHOIS contacts, but don't expose that information after registering - I emailed to ask because I didn't see a whois privacy thing during checkout.

oh hell yeah, thanks for this, had never even noticed before there was a radio tld

if you can get that to the point where somebody can buy a box and get a 7 or 10 inch touchscreen hooked up you would make a mllion dollars

even just an HDMI out would be so amazing

concur, literally the only thing i dislike about the 7300 is the tiny screen; there’s wfview, but it’s not the same

I was thinking of going for the first time this year because there’s HamSCI booth and I’ve been trying to contribute to that project off and on over the last year, but getting to Ohio on short notice wasn’t going to work out - I’ll probably go next year though.
