Ham radio always seemed a bit boring compared to the Internet, computers, and software development.

What are the most interesting things people are doing with Ham these days? I’ve had a technical class license for a couple decades but never used it, which I keep renewing. Willing to get a more advanced license.

Check out https://github.com/drowe67/radae. David Rowe has been working on a really neat new digital mode for audio transmission over HF channels, using a pretrained autoencoder. It's currently getting integrated into the freeDV gui in this branch https://github.com/drowe67/freedv-gui/tree/ms-rade-integ

That reminds me. I'd like ppl to get excited abt the "codec2" open source replacement for c4fm, p25, and dmr... unless sth newer is out there

My son and I listen to DMR and P25 all the time, and we listened to a bunch of the samples of Codec2 vs AMBE. And while it might be a slight improvement, it doesn't move the needle enough to really excite. Perhaps a longer QSO would be more exciting to hear the difference on. Wouldn't hardware be a constratint just like it is with M17?

For me it's not the sound quality (as long as it's comparable), but the ability to use digital modes on any radio without vendor lock-in!
