[Elecraft] K2 receive sensitivity

[d.cutter at ntlworld.com]

The G2DAF receiver did it for me when he demonstrated gain and s/noise ratios.  A friend built that rx and it was completely different to others I had listened to.  If I remember rightly he had no gain in the front end, only matching to the antenna and input filters; all the gain was in the IF.
