You may recall that the HB100 is a very low cost Doppler radar module that can form the heart of a wideband FM 10GHz transceiver.
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.
We live about 15km from airbases used by the USAF. In the last couple of days these appears to be an increase in air traffic.
