This rig is many years old. It is simple, but it worked lots of DX.  As I recall, it produced about 500mW of CW. See  https://sites.google.c...

This was created before the last sunspot peak. Although many have migrated to FT8, nothing beats working DX on a simple transceiver that you...

Hopefully, this will spark some ideas. I build this rig on the up-slope of solar cycle 24, but with cycle 25 now in good shape, it should be...
