[Elecraft] K2 Settings Retrieval Software

[Don Wilhelm]

Actually, the K2 settings are quite stable.  I would recommend using 
this software to record the settings right after an alignment, then 
remove the cable.

If the BFO settings are to be re-installed, know that the 4 MHz 
Reference Oscillator may have drifted since the last alignment.  If it 
is set correctly again, then the same BFO frequencies can be entered.  
Note that the BFO frequencies should be regarded as +/- 0.02 kHz because 
of the BFO DAC resolution.

If you need information for accurately setting the 4 MHz Reference 
(C22), look at my website www.w3fpr.com article on K2 Dial Calibration.
