[Elecraft] K2 with HRD freq wanders

[Don Wilhelm]

Eric,

It really is hard to say what the cause is - there are several 
possibilities.

It sounds like noise on the cable between the K2 and the computer - 
which is causing the data *to* the computer to be corrupted.  Since the 
K2 changes frequency correctly, the path *from* the computer to the K2 
is likely ok.
Try a different serial port if possible or a different computer or if 
you are using one, a different USB to serial converter.

If that does not help, check the negative voltage supply on the KIO2 
option.  If the negative voltage to the MAX1406 chip is missing, the 
signal may not swing low enough to satisfy the receiver in the computer 
(or USB to serial adapter).

73,
Don W3FPR

All works fine in HRD but after clicking on a K4M spot, the K2 goes to the right frequency but then random numbers appear slowly, one by one, in the hrd freq display.  If I click on another dx frequency, the k2 goes right there but then the random number cycle starts again.  K2 does not change frequency.  Any ideas?  It didn't do this before.
