come to think of it I have a fisher 400 that I have never been to keen on the separation. the tape output/dual scope/stereo xmitter/tone generator is a pretty good way to set that 38khz coil. When I get some of these TV's out of the way I may have to go back and work on that one.

I really think removing that resistor is a mistake. I checked both my combos again last night and they have great stereo separation with both channels going. With only one, yes there is some bleed over but it seems to go competently away with both signals.
The fm multiplex we use is the Zenith system and invented by Zenith. They knew how to do Stereo and I really doubt they would intentionally cripple their unit with a single resistor.

forgot to mention, I did put it back, and it did IMPROVE the stereo separation with the MPX. Not sure what the deal was but yes you are correct, leave it as designed. that last scope pic was with the resistor back in.
