This was a design for a tiny QRP CW transceiver for 40m CW. This short video shows the radio with a digital display, which was non-standard.
See https://www.norcalqrp.org/files/49erOrigMnl.pdf
Kits are still available.
Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.
Buy me (a virtual) cup of coffee
This is NOT at all compulsory, but this would help offset some project costs.
Any donations most gratefully received.
