[Elecraft] Help!!...I'm in trouble...

[Phil Wheeler]

Ron,

When I built my KPA100 and installed it I had two problems which could 
be related to your situation.

1.  When re-installing the SSB board I missed on one of the connectors. 
The result was very weak receive. Pulling it out and redoing the install 
fixed that.

2.  I could not find my anti-static wrist strap and zapped the MCU 
(which Elecraft later replaced).  This I verified by putting the old one 
it and finding that the rig worked as usual -- but not with the KPA100.

Before doing a reset I would R&R the KSB2 and measure all voltages on 
the control board (note that most are done with the F'Panel removed). 
 And check all the control board mods again.

73, Phil
