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.

Don't forget to shunt the captor coil of the toroid, with a low value (100 ohms) resistor. To avoid to choke the RF. Some cores take temperature, with only 5 W.
