Just dropped 3dB now - as there are more stns on and monitoring. &= nbsp; next drop will be in 20 - 30 minutes

Dear Andy,
 
if you want to change power it mig= ht make sense to go up and down on a shorter timescale, as otherwi= se it may be difficult to tell the effects from a generally increasing=20= noise background. I'm seeing your signal weakly on spectrogram with a li= ttle doiwnward drift, but no decodes yet, so not much hope for QRPP this way= .
 
I have now set up WSPR for LF= /MF half duplex, transmitting 25% on 137.568, and listening around 503.= 900 inbetween.
 
Kind regards,
Markus, DF6NM

I'm WSPRing again.  Tere was a request earlier this week=20= for some more QRP operation, so I've put a switched attenuator into circ= uit ready.  Currrently running at the original 80 Watts figure, but thr= oughout the evening, I will progressively reduce power in steps - unles= s there are any requests for specific reductions.   Fully linear s= ystem and I have 1dB resolution available.
 
Suggestions pse for power levels.
 
Also do have the margin to increase power by about 2 - 3dB as well,
