Ron, I think you misunderstood what I said regarding adding the 1K across the LED. I did not suggest removing the 390 ohm shunt resistor which was placed across the series combination of the LED and the 1.1K. What I meant was to add the 1K in addition, directly across the LED, not across the series combination. This will reduce the sensitivity of the LED so it should go out when not receiving stereo. Before you button it up, you might give it a try.
In any case, congratulations on getting the MPX board and the rest of the receiver working!
