Joe,
when you were sending CW a couple of days ago, the
coherent carrier was detectable in my 438 uHz spectrogram in
broad daylight, until 12 UT! So I'm wondering how a low power straight
carrier would fare during night and day?
Best 73,
Markus

Hi Hartmut,
Yes, DCF39 must be a real pest as it is so
close geographically and
in frequency. You seem to be dealing with it very
effectively.
Thank-you for running the grabber.
It's a pest over here
too, but sometimes useful to check the RX system.
The TX will be on again
tonight. In keeping with the spirit of energy
conservation being requested by
our power company, the TX will run
at <5 watts tonight to the 100m
wire. I hope to watch for the signals
on your
grabber.
Cheers
Joe VO1NA
