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,

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.
