Not much left to the imagination now!

VOR does shutdown sometime in the day so that may be what's happening.  The info I have says '2000-1600UTC daily'...  Perhaps it will start soon and wake everyone up in Komsomolsk?

Hi Scott, LF,
 
I've temporarily tuned the grabber to 153 kHz, inserted a 20 dB pad, and slowed down the TA window to 10.5 mHz resolution, 30s scroll:
I intend to leave it running for a couple of hours, and bring it back to 137 before going to bed.
 
The cyan line on 0.0 Hz is DLF Donebach at ~ 277°, with weak sidelines at  0.2 Hz multiples from the data frames. I have placed a null on it, but the E-H cancellation is incomplete due to skywave QSB effects. 
 
The strong orange line at + 0.525 Hz is clearly Brasov (Romania) at ~140°. This is most likely the "new unid" in your spectrogram.
 
I can't make out Bechar Algeria yet (should be green and strong), but if it's on frequency I couldn't separate it from DLF here. Same perhaps for Ingoy (Norway, dark blue).
 
No signs of "VOR" Komsomolsk at + 1.5 Hz either, but that may simply be too far.

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
