Dear Group,

this screenshot from 03:00 shows DJ8WX in blue on 135922.22 and an unid green signal on 923.50. Judging by frequency, direction and strength this looks very much like CT1DRP - but what was the modulation used? The symmetrical blur with 0.125 Hz spaced lines resembles QRSS-8, but I failed to find the gaps in the faster spectrogram. So my guess is PSK at 8 seconds per bit, with a 15 or 16 bit message repeated every 3 minutes.

Any clues?
