By the way, as an employee of a company developping, installing and mainta=

Yes, and it's strong enough on the DK7FC grabber to see a samplerate alias=
, stepping down all the way to 18 kHz.


Yesterday Klaus DJ6LB near Nuernberg improvised a DF loop, and got approxi=
mately 70=B0 / 250=B0 azimuth. So Russian origin would be a possibility.=
 Any other measurements available?

Kind regards,
Markus (DF6NM)
