[Elecraft] Mic Problem?

[Jim Wiley]

Ken -

Something similar happened to me when I was building my K2.  In my case, 
it was a bad PROM chip on the DSP unit.  You didn't say whether or not 
you have the DSP installed, but I suspect the same sort of problem could 
occur with other modules.  In my case, as I cycled through the filter 
and mode settings, the K2 would act almost normal for one turn through 
the options, and really weird the next time around.   The tinny audio 
and intermittently garbled audio were some of the symptoms my unit 
exhibited before changing the chip.  In my case, since the bad part was 
on the DSP module, removing the module and jumpering the connections 
restored the rig to normal operation.  That may be something you can 
check, removing an option module and temporarily bypassing it's 
function, that is, to see what happens. Possible things to check:  Did 
you make sure every pin is soldered properly on the PROM chips, wherever 
they appear?  Maybe that's a clue, maybe not.  I am sure others will 
have additional information.  Good luck!
