Re:Show HN: A new protocol for packet radio including ECDSA ... by prolikewh0a on Monday September 24, 2018 @12:06PM (#18058833)
I've actually seen my young amateur radio communities die off during this new solar minimum, and a lot of my friends sold their expensive equipment. You really need money and space right now unless you want to sit at your desk and do some of the new low SNR "can talk to the mars rover with a wet sock as an antenna" modes that a lot of people don't like because it's too easy and poses no challenge. There's also VHF/UHF, but that's mostly older clique's.

It's definitely a slowly dying hobby.

You should be able to talk to anyone in the USA with 100W and a wire antenna.

I think the bigger issue is noise in urban areas. The FCC does a shit job of regulating noisy equipment. I had to go through my house and dispose of certain Ethernet switches, an audio device, notebook power supply, etc.
