Dear Andy,
 
if you want to change power it might m= ake=20 sense to go up and down on a shorter timescale, as otherwise=20 it may be difficult to tell the effects from a generally increasing noi= se=20 background. I'm seeing your signal weakly on spectrogram with a little doiwn= ward=20 drift, but no decodes yet, so not much hope for QRPP this way.
 
I have now set up WSPR for LF/MF=20= half=20 duplex, transmitting 25% on 137.568, and listening around 503.900=20 inbetween.
 
Kind regards,
Markus, DF6NM

Suggestions pse for power levels.
