K2 problem

Ian Maude
Hi all,
Well I thought I would have another go at calibratign my K2 after a
couple of years and I have broken something.  I have no RF audio.  
Sidetone is fine and I get a click on switch on.  I suspect the KDSP
board.  I do not see the LED at all on switch on and the K2 does not
think it is installed.  Is there an easy way to take it out of circuit
physically to narrow the search please?

Ian,

Is it possible that you plugged the KDSP2 in with the pins offset from
the headers?  That would kill the audio in your K2.
If you find no simple answer, unplug the KDSP2 and bend a couple of
component leads to fit between the 2 control board headers - J1 pin 1 to
J2 pin 1, and J1 pin 2 to J2 pin 2.  No need to solder them in, just
push the wire ends into the headers and 'presto', you have created an
'unmodule' - it works for me that way.
