KXV3B installation problem

[Al Van Buren]

Hello,
  I upgraded my K3 ser# 6360 with a new KXV3B module and now is
doesn't TX or RX. I thought the new module might be defective so I
put the original KX3B back in with the same results. I did a
synthesizer calibration but that didn't help. I get no error
displays. With the new KX3VB module I get an increase in RX white
noise when turning on Preamp 1 but a decrease when turning on Preamp
2. Also, the transverter outputs do not work.  The Sub RX does work
however.  Any suggestions on what to check?  Thanks, Al K7CA

Hi Al;
Most likely is the little Sub-In board is off a row of pins.
Or possibly the KXV3 has a missed pin.
Or one of the little black cube chokes (L1,2,&3) on the Sub-In board got
knocked off.
(I assume you have the KXV3B in "nor" and you have tapped 9 while in
that menu to toggle the "B" on.
Then cycled power to make it set.
