LF: Re2: More QRM from Donebach?

["Markus Vester" <markusvester@aol.com>]

Unfortunately the QRM returned tonight 19:00 UT:-( 

 

Thanks to Hartmut for the feedback. Yes, the problem may well be related to the new DRM / Simulcast transmitter in Donebach.

The sidebands were up to 35 dB over nighttime background noise here. They went off suddenly at 07:10 UT, hopefully for good...

Hi LF,

 

since 19:00 today, intense splatter appeared above about 137.2 kHz:

Direction of arrival and correlation to the Deutschlandfunk modulation both indicate sidebands from Donebach (153 kHz) as the source. Anyone else noticed this problem?

 

CFH is also strong on 137.0 now.

 

Best wishes to all
