Hi Markus


saw both your nighttime and morning emissions, ufb signal up to
10dBµV/m with QSB, drifting very slightly from 137769.93 to 769.96Hz.
Last night, I joined in for a while:
 23:16...23:52 on 137698.5 QRSS30 and
00:01...01:57 on 137699.95 / 700.05 DFCW(60+20).
Thank you for your report. Your  measurement put my frequency higher than I
thought it was.
I use Argo for frequency measurement. I make a calibration on 60kHz Rugby by
setting the receiver frequency dial to 59kHz USB. Rugby comes up at 1000Hz.
I then put the cursor over the signal and switch to narrow band mode 60s
dots. In my case the signal registers .2Hz high.
I have repeated the test with DFC39 and that is .5Hz high and the BBC on
198kHz is .6Hz high
Does anyone have an accurate measurement of the 'French' signal near 137750?


With the green absorbers well frozen, aerial efficiency has gone up by 2dB
to 0.135%, ie almost 0.5W E(D)RP from 200W TX power,
including a few sparkling corona lights.
Your signal is much stronger than it used to be although I have not actually
measured it. A good antenna to put out such a good signal with only 200w.

Regards,
Peter, G3LDO
