I can see the "distortion" with the sig gen at -30dbm. Below that my scope
can't see it very well. The radio station signal shows at about -12dbm on my
spectrum analyzer at the antenna.
BTW, during the day the 1650KHZ station signal comes through at +60db on my
carrier level meter when tuned to 3300KHz. I just checked my R-392 as well.
It is hearing it now as well. At night the R-392 does not hear it and the
R-390a signal drops to 40db on the meter.
I may just have to build a high pass filter like DW suggested. It probably
wouldn't bother me if it registered a few db on the meter, but 60db just
doesn't seem right. Especially after reading for years about the great
strong signal performance of these receivers.

ps: Hope this doesn't show up twice. I got a "bounce" notice from the
reflector.
