Curious Signal on 10
Image icon Curious_Signal.png108.51 KB

There's been a peculiar signal on 10 mtrs this afternoon. Intermittently recurring fast bursts of tones with an approximately 20Hz bandwidth. Sometimes a smoothly sliding tone either up or down but more often a very fast chirp-like or raspy sequence of tones. No apparent pilot tone to anchor the spread of tones. I wonder what it is... some kind of iono-sounder? Some sort of new digital mode?
