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

Hello Joe,

thank you for your kind words!

Still struggling here with my local Pest DCF39. Between 03:15 and 04:40 UTC DCF39 was sending a higher pulse frequence. That is the reason of the higher noise level at that time and poorer reception of your beacon.
Thank you for your signal!

Hello Hartmut and Group,

Even with only 65 watts from the TX, strong QRSS100 signals were seen on
Hartmut's grabber at 137.777 so the power was cut to <10 watts by
reducing the drain voltage of the class E amp to 12 V. The grabber
traces faded substantially, but rebounded to clearly readable around
0630 utc.

Congrats on your impressive RX setup, Martmut!
