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

[Brooke Clarke]

Hi Trish:

It's my understanding that Cubic has done a lot of work on eliminating noise coming in on the power line specifically 
for VLF reception.

I can't over emphasize how important bandwidth is when looking for weak signals.  Noise = kTBR, so lowering Temperature, 
Bandwidth and/or Resistance lowers noise.  The next improvement comes from using a matched filter.

But that usually requires that the transmitted signal be in a special format.

Have Fun,
