Yes, Simon, you will likely find that the sloping signals drifting
across the waterfall are caused by local switched mode PSUs. Perhaps
your own?
I have found the P3 causes some interference on 2 metres. This was cured
quite simple by placing a ferrite clamp-on at each end of the power

There will be some latency - so you have double latency - once through
the KX3 and again through the panadapter software. That may or may not
be troublesome. If so, the only cure is another soundcard and the cable
