  Bob, I guess I missed this in the FAQ:

"Analog or switching power supplies themselves are highly susceptible
> to RF. A few millivolts of RF in the power supply can create an
> instability which could lead to a catastrophic failure. We never
> recommend regulated or switching power supplies because no one can
> predict when RF is upsetting the power supply and all installations
> differ in characteristics."

I can definitely imagine my 20 foot combination coax/power supply line 
acting like an antenna.

So now all I need is a recommendation for a small UNregulated 12VDC 
power supply that isn't a "wall wart".
