[Elecraft] Using a Softrock Lite 6.2 as a K2 Panadapter

[Jack Smith]

I've completed a detailed analysis with measured data using a Softrock 
Lite 6.2, K2 IF version as a panadapter.

The details are at a new web page: 
http://www.cliftonlaboratories.com/using_softrock_as_a_panadapter_for_the_k2.htm

The measured data shows that the Z10000 buffer amplifier is quite 
efficient at handling the Softrock's LO leakage and also that setting 
the Z10000 buffer amplifier to provide around net 0 dB gain (1 uV into 
the antenna port at, say 7 MHz, corresponds to 1 uV out of the Z10000 IF 
sample port at 4915 KHz) is about right with the Softrock. Some may 
prefer a slight bit more gain, which may be achieved by a different gain 
setting resistor in the Z10000. The need  for additional gain may be 
more important for VHF/UHF work, or quiet band conditions. In my tests 
with  both lab  gear and listening on 40 meters, I did not find 
additional gain necessary.
