[Premium-Rx] SAQ Broadcast

[Clemens Paul]

Hi Tom,

here in southern Germany (near Munich)  it was easy to get a Q5 copy of the 09:00UTC 
transmission and
I' ve done some records.
I've used a Telefunken E1800 and my SW-dipole with 2x46m and 42m open wire feeder,ends connected
together,without any matching device.
I will watch out for the 13:00UTC transmission,too.

  Greetings!

  Did anyone else here try for the SAQ (Grimeton, Sweden) Alexanderson
  Alternator broadcast at 0900 UTC? It gave my Premiums a workout on
  VLF, but with mixed results.

  Broadcast frequency was 17.2 KHz. I've tried for it before, but THIS
  time I thought I might actually copy it. Propagation conditions are
  VERY good right now on VLF, but it appears that the propagation was
  going NORTHWEST and WEST rather than northeast over the pole to
  Sweden.

  The weather here is PERFECT; clear, and very cold (about 3 degrees F)
  and at 3 AM local time the overall noise level is VERY LOW.

  I managed to get THUNDEROUS signals out of NWC (Harold E. Holt,
  Australia) at 19.8 KHz, and NPM (Lualualei, Hawaii) on 21.4 KHz.. I was
  even copying a weak but steadily readable signal on 18.6 KHz (a US
  Navy TACAMO aircraft frequency).

  When 0900 UTC came up, I could barely preceive a WEAK signal on 17.2
  KHz, but too weak to copy the CW. Another close by carrier made things
  difficult too (no doubt some industrial interference). The RA-6778C
  was producing the best results; I was cranked down to the 150 Hz filter
  in the IF, and BFO offset to +400 Hz. My DSP box didn't seem to help
  any on this one.

  BTW... re. antenna: I used the quietest antenna (S/N ratio rather than
  sheer physical size), in this case a short random wire.

  This is the closest I've come yet to copying a Grimeton test broadcast,
  and we're almost there I think. At least we heard the carrier, even tho
  we couldn't make out the CW.


  73's,

  Tom, W9LBB
