Had a report that my LF WSPR2 signal was dirty with massive side bands
on Sunday. I had a look at my setup today found Windows had decided to
up the audio level from WSPR to maximum into the TS-590 and scoping
the output of the pre amp and frequency doubler before my G3YXM amp
showed it looking very ropey indeed.

I reset it and did a couple of normal WSPR2 transmissions interspersed
with using the WSPR TUNE function, whilst watching on the G3XXM and
G4WGT LF grabbers. I am no expert whatsoever, but it doesn't look bad
now to me. Is this an adequate test to make and to assume things are
now OK? Thanks.
