[Elecraft] Re: Lost Sidetone and Spotting Tone

[Bilbirt@aol.com]

David,
 I've just finished putting the KPA100 and KAT100 into an EC-2, and went through
the same problem as you describe when I was first checking out the KPA100 in the K2.
I had just replaced the IOC and MCU chips and did not have either tone; changing the
source in the menu didn't have any effect either.  I swapped the original chips back in and
the tones were back.  I thought maybe I had a bad chipset, but put the new ones back
in a second time.  Around this time I noticed in the menu that the sidetone level had been reset
to zero; I didn't think to check that before swapping the chips out initially.  I touched up the
solder connections around those sockets as a precaution, although they all looked good.
73,

Subject: [Elecraft] Lost Sidetone and Spotting Tone

I just completed and installed the KPA100 in my K2.  I did not yet do the 
Control board modifications for computer control.  Everything checks out OK 
except I have no sidetone or spotting tone, either with the KPA100 or with 
the basic K2.
