ARLA/CLUSTER: Vídeos de contatos em 144 MHz via Aurora Boreal

[João Gonçalves Costa]

144 MHz Aurora videos

David Bowen 2W0ZJA, in grid square IO81gx, has made available two videos showing 144 MHz during the Aurora on July 15.

Auroral propagation makes SSB signals sound raspy, whisper-like, watery, and sometimes very difficult to understand.
