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.
