Hi Scott,
 
sounds like a nice challenge for my colour-DF system...
 
Donebach is GPS and Cesium controlled so the carrier should be accurately on frequency. At 160 km, they are overwhelmingly strong here, and there are close-in sidebands from low datarate DGPS signalling ("AMDS") and dynamic carrier control. Even with about 30 dB directional nulling (left part of screenshot), there is nothing else to see in daytime.
 
I will try to take a more detailed look tonight, when the DLF level should be significantly reduced due to power reduction and transmit antenna pattern switchover.  
 
Best 73,
Markus (DF6NM)

  Would someone with suitable equipment in Europe mind taking a look on 153KHz and sending me a grab of the carriers there?

I would like to sort out who's who.  If you could null some of the carriers to determine rough bearings from your QTH that would be great!

I understand the following stations are on 153KHz world wide:

   a.. Antena Satelor / Radio Romania - Brasov, Romania - 1200 kW
   b.. Chaine 1 - Béchar, Algeria - 2000 kW
   c.. Deutschlandfunk - Donebach, Germany - 500 kW (250 kW night)
   d.. NRK Finnmark - Ingoy, Norway - 100 kW
   e.. Radio Rossii - Komsomolsk, Russia - 1200 kW  (presently known to be at ~153001.5Hz)
from
http://wiki.mayson.us/wiki/List_of_longwave_broadcast_transmitters#153_kHz

I regularly see a carrier bang on 153000 and one at 153000.5ish during time of propagation to EU.

Thanks,
Scott
