K3 3422 gone deaf

[David Christ]

I got a new 6k filter for my K3.  I installed it as FL1, moved the
2.7k from FL1 to FL2 and the .5k from FL2 to FL3.  Changed the
configuration to match the new hardware.  Then without verifying the
installation I installed MCU 3.68 with Utility 1.2.8.  Noticing that
I was supposed to use Utility 1.2.10 I downloaded the new utility and
reloaded 3.6.8.  Rig is now effectively deaf.  Sounds the same as if
there is no antenna connected.  No change in background noise when
antenna is connected.  Switching from ANT1 to ANT2 and back causes
relays to click but no change in sound.  I verified that the antenna
is OK with another receiver.  Extremely strong signals can be barely
heard so it is not totally dead, just has ear plugs in.  From what
little signal I get, the attenuator and preamp seem to work.  Tonight
no strong signals so nothing but gentle hiss.

Installation was done on an anti-static mat with a wristband.

Any suggestions on where to start would be appreciated.

David,

Open the top cover and check the plugging of all the TMP cables as a
good starting point.  Check all the areas that you disturbed to see if
anything is out of place.
I doubt the firmware is the problem, but you could certainly try another
firmware load just to be certain.  Make sure the firmware finishes
loading - if it is abnormally terminated, the K3 will not work.
You could try an EEINIT and then set up all the menus from scratch.
