[Elecraft] Checking K2 sensitivity...

[Dave G4AON]

There was a problem with "transmit power" and RX sensitivity on early 
K2s,  my K2 serial #1892 had this problem. Basically the tuning cap(s) 
in the band pass filter needed a fixed capacitor of around 10 pF across 
the variable as it was right at the end of it's tuning range, you might 
want to check back through the list for details.

My K2 gives 0.12 uV sensitivity for 10 dB signal to noise without the 
pre-amp, and 0.1 uV with the pre-amp on.
