[Premium-Rx] Looking for recommendations on high performance VLF receiver.

[Tom]

Hi Folks!


  I've been having a blast pulling in VLF aircraft beacons in the 200-525 K/c range.

  I am looking for recommendations for a premium receiver that will cover VLF. If it can cover say VLF to HF (maybe 10k/c - 30 Mc, that would be even better!)

  Due to the nature and spacing of the signals, selectivity is an absolute must!  Signals can typically be 2 K/c apart from each other, creating all sorts of heterodyne issues.

  My best receiver is the CEI-357 (R-1401): Sensitivity is good, selectivity is also quite good, but the noise blanker doesn't seem to work, and this a real performance killer (especially since we're getting into the noisy time of year!).

  The CEI-357 has 6 K/c, 3 K/c, 1 K/c, and 100 Hz filters. For VLF work, the 3 and 1 K/c filters are what I primarily use. The 1 K/c filter gets used the most. Being able to use a .5 K/c filter would be a huge asset for pulling in the Canadian beacons that have the 400 Hz modulation.

  Having the ability to go from AM to USB and LSB is also a huge plus: I bagged a beacon in the Caribbean (a 3900 mile path!) because I was able to switch to SSB and use a narrow filter.

  Thanks in advance for your suggestions.
