[Elecraft] K2 Chirp

[Glenn McNeil]

Hi Group,

I've just recently finished a K2, S/N 4630. It has DSP, SSB, 160M 
Option,KI02 and the  K60XV.

All appeared well until today, when I noticed that tapping the DISPLAY 
Button from the frequency display to the DSP Menu, I get a cyclic 
beep...or burp. It changes frequency from DSP on to off. It only does 
this when in the DSP Menu. It is internally generated, as removing the 
antenna lead from driving two XV Transverters still has it burping away 
at a one second rate. Removing the KI02 leads to the Transverters still 
has the thing happily chirping away.

I've stepped through all bands , 160M thru 144 Mhz. It is evident on all 
bands except 50Mhz. It varies in strength from Band to Band. Unplugging 
both Transverters has it still burping away ( Power leads and the KI02 
Interface leads ).

I don't know if this has just become active after fitting the K60XV, as 
I cannot remember noticing it before I installed the K60XV. I did have 
to move the VFO tuning on L30 to accomodate the 60M Option, as it would 
not lock. All band VCO Voltages moved upwards, with my max voltage about 
7.4, and my min just a shade over 1.1v as per the destructions if any 
one band was out of spec.

It only does this when you can see dSP  bYP or dSP ON, or when you are 
looking at the DSP settings.

Any help/advice on what this annoying burp is would be much appreciated.
