Not sure what's going on here... This would be a spectrum image (30m) from essentially dc to just beyond 5kHz.
We see RTTY, PSK31 and WSPR (at about 2.7kHz). And, we see two strange noisy snakes, about 500Hz apart. Any idea what that could be?
Half of the image was taken with the aerial (rockloop) pointing North-South, during second half of that spectrum scan, the aerial was pointing East-West.
