[Elecraft] K2 mic audio thru speaker

[Don Wilhelm]

Ian,

The mic audio in the speaker is definitely not normal.  That says you 
have something connected incorrectly.

First question is - did you remove the KSB2 board during the K60XV 
installation?  If so, check to be certain it is plugged in correctly.

Next, is the problem seen only on SSB transmit for 40 and 60 meters?  
Check some other bands.  If only 40 and 60 meter bands, check that the 
K60XV board is plugged in correctly.  It is not the easiest thing to get 
those pins aligned right, you have to peer under the board to get both 
the 3 pin header and the 8 pin header aligned at the same time.

If neither of the above are the problem, check your installation steps, 
particularly the points where the coax on the bottom of the RF board end 
points are placed.  It sounds like you may have soldered the J13 end of 
that coax to the wrong pin and that could feed a bit of transmit RF back 
into the receiver.  If your K2 SN is less than 3000, make certain the 
trace cut is complete.

73,

Is there some deep menu opition I have some how channged, or have I done something else...? I can't think of a real use for a mic-through-speaker option - it just gives AF feed back.
