A compact CB transceiver would be fun.
- topspin 5mo agoFun, but short range. A quarter wave CB antenna is about 2.7 meters long. Without that, you're making more heat than radio.
- iberator 5mo agowspr is known to work at 7mhz band with just cloth hanger as antenna. i think its totally possible to use headphones as shitty longwave antenna too
- jimnotgym 5mo agoWspr is very optimised for weak signals, though. You wouldn't actually hear anything but noise.
- iberator 5mo agojt8 would work. designed for ultra low db reception. We are talking here -20 dbm and chattable
- topspin 5mo agoSomeone already pointed out how the WSPR anecdotes fail for CB. The longwave reception argument is fallacy as well. There, you receive powerful signals with a poor, receive-only antenna; the typical asymmetric model of commercial broadcast radio (and cellular, for that matter.) With CB, both sides are low power. Legally, that is. And neither antenna is on a huge tower. Several handheld CB radios exist, with little loaded whip antennas. You can go buy one. You'll see. They work for talking between two tractors in a field or whatnot. Past that, not so much. Today, you're better off with license free UHF handhelds for that use case.
