Giving another run through the list a bit later tonight (04.38 UTC):
OK - good, strong, clean signal
Something - possibly WW, though maybe MO or TMP - around 4.078 - not enough to see clearly, even on the spectrogram; not consistently audible above background without the screen to look at
Ditter at 4.089 - again, almost-but-not-quite. Just enough audible to think there might be something there, with a column of ants just visible in the right place on the spectrogram
Pike 78 - some fading, but strong when it's up
TS - pounding in strong, with easy copy and clean signal
