[TenTec] Orion - No Receive - No Audio - No Transmit

[Rod Parks]

I have an Orion that has no receive or audio from either receiver.
While in CW mode, can not hear the spot tone when spot button is pushed.
All buttons and knobs function. I have cleaned all board connectors by
removing each board from the A11. Cleaned all TEMP RF connectors. Have
replaced the Dragonball CPU (not an easy task) with the same problems after
replacement. One odd note is the DSP number that shows on the display when
booting or when MENUS button is pushed for 2 seconds or more is DSP
-0.01B-1.
I have tried firmware versions 1.XXX, 2.XXX and 3.XXX and still have the
same issues.


Any ideas would be appreciated.
