Good point Bill. 

As Ten Tec ALWAYS told folks on the phone, if you are having trouble with just about anything regarding flakey problems like this, recap the A9 board.

I have cured several Orion’s with this repair.

The last thing I did was to DeOxit ALL connectors in the radio (quite a job). It has never had a problem since.

>> Hallo everyone,
>> I'm a happy owner of a Orion since 2005. Today, while it was transmitting my home energy was suddenly interrupted. After switching the RTX  on, it started behaving in a strange way: both VFO seems ok but no band reception; only the buttons around the display are active, the others don't  work; no transmission. I performed a Master Reset and then a Ram Clear (followed by a master reset). Now it switch on, the volume goes up an down, some noise comes out from the speaker, but the 20m are silent, only electronic noise.
