Desperate strokes

Still fighting the QRN here, though the nature and strength of it keeps changing, making it hard to assess the effectiveness of different sense antennas for the MFJ 1026 noise canceler. I'm currently using a SuperAntennas MP-1 for the noise antenna. It's fiddly to adjust, as always, but when tuned correctly it pulls in a big noise signal on 20m which enables me to cancel the noise very effectively.

It is no help at all on 80m though. I think I'll just have to abandon that band. My short dipole has a pretty narrow bandwidth and is not all that much use on 80m anyway,
