Bob, I guess I missed this in the FAQ:
"Analog or switching power supplies themselves are highly susceptible

> instability which could lead to a catastrophic failure. We never

> 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".
