reqack I've updated the CEC firmware to version 4732, but I can't control it. My main problem is that I don't know how to search for channels.
Gintoki reqack With the UVK5 module, which does not require modification, it supports receiving shortwave signals with a frequency of at least 15 MHz. Using the Shikawa antenna, you can receive shortwave signals.
CqHam The K6 is essentially a handheld device, and it's fine for casual use. However, if you want to listen to shortwave radio, buying a dedicated receiver would be a better option.
