alt Hacker NewsI can't keep up with the rapid, non stop cool stuff being discovered! Someone figured out how to get the ESP32 to transmit, at lower bandwidth (I think I read 200-250khz) I don't know which project it was but there are a bunch on this site:

Holy cow... I've got to limit my projects, so I don't repeat history where I kept finding radio shack bags full of parts for ideas. But you can get 3 of those, with external antennas for less than $60 through amazon. I put it in my wish list instead of buying them now. I've got a data diode to finish first.
Sideband on 13 CM sounds like an amazing thing to pull off.
