This is a mode of message transmission I had not heard about before. It is claimed messages can be sent using extremely low power using chirped signals. I am no expert at all on digital communications!
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.
