Neil,
These old Drake rigs are communications rig, not general coverage SW rigs.
Drake did make models that are, but not your R4A. There are circuits to
deliberately block these "strong AM stations" so that they do not interfere
on 160m (1.8 to 2.0) or their images on 80m even. Without defeating the
input filtering, you are just stuck with what the Drake designers had to
fight, AM interference from strong broadcasters on the lower ham bands.
Neil, I mean this in a positive way, so don't take it any other way, but you
ask an awful lot of questions and it would be helpful if we know if you are
a ham or not, and some about yourself so we have an idea of your level of
radio knowledge. That way we don't give dumb answers and can tailor
questions better to that level. I am an old, retired educator and always
did a better job knowing what my students knew.
73,
Don,
