Here in Mpls 1500 AM is occupied by KSTP, and very powerful station, and on my 41-295, it resonates on 590 and to a lesser extent on 1045, approximately.
Is there something I can do, short of adding a wave trap, to prevent the I.F. from resonating like that? I've done a complete re-cap, and replaced most of the resistors as well, but except for the pushbuttons, I've pretty much left the mica caps alone. Should I look more closely at the mica caps near the oscillator?
A friend with a 40-201 reports the same problem, only worse. I re-capped that one, too, so I'm willing to admit fault if I did something wrong.
Anyone else have this problem?
