I'm curious though - these spurs come through even
when the aux antenna isn't even selected. I'm
listening with the main (not aux) antenna selected and
the spurs appear with the Beverage plugged in to the
aux jack, and disappear with the Beverage unplugged.=20
And I'm talking a full S7 spur on 3510Khz. =20

If it's simply sigs coming in through the Beverage,
shouldn't the main/aux switch cut them off?

Sounds like you may have blown the protection diodes in the aux ant =
ckt. You may find some info about this in the Reflector archives. Poor =
isolation can also cause RF to feed back into the xmtr (depending on =
power level) thru the Beverage port causing flakey sounding xmited sig =
etc. Good luck es 73 John WA4TT
