Hello Mike and Alan,
EIRP of DCF39 is about 40kW (+/-46dBW), so ERP about 44dBW
Few hams reach the 1 W ERP limit , most are even 6..10dB weaker.
So the "gap" is at least 44dB maybe even up to 50dB.

Alan,
yes, it appears very likely that DCF39 is reaching us. As far as I can
ascertain the first traces appeared when the gray line was about Moscow;
maybe 2000km from Magdeburg?
That 36dB advantage of DCF39 looks like a big hurdle to overcome. However
the signal was very strong at the 60 second dot setting and also the keying
sidebands were quite clear and there can't be much energy in those relative
to the carrier. I will try the 20 second dot setting tonight. Bob ZL2CA will
also be watching.
