[Drakelist] Overload

[Neil M Califano]

I located a crystal to cover 1 to 1.5 Mhz, below preselector range for my Drake 
4A. Some MW stations are tunable down to 1.3 mhz, but there a few very strong 
broadcasters just under 1.5 Mhz and I hear a lot of static crashing. Is the 
front end overloading? I realize an AM table radio is only a few dollars, but 
it is convenient to tune them in on the R4A.

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,
