[Elecraft] Now what did I do??

[nr5a]

I pulled the KAT-2 out of my K2 because it looks like I've managed to blow 
the diodes out for the 2nd time. How hard is it to remove it? What could I 
possibly screw up? Take the top cover off, pull the 2 cables, take the nuts 
of the 2 bnc connectors and remove the ground lug. I mean what could I 
possibly have done?

Next hooked my T-1 auto tuner in line, went to menu and changed InP to Hand. 
Check it and that works just like its suppose to.

But................... my sidetone is gone?? What did I mess up this time 
and how?

Some years aren't my year, maybe 2007 will be better??
