[ARC5] Vintage LF/MF Fun with my BC-453B

[Dennis Monticelli]

Mark,

That is a fun thing to do.  10 yrs ago I did the same thing with a rebuilt
BC-453B.  One tip I will pass along is to use batteries if you can,
especially the B+.  I ran eight 9V batteries for B+.   Divorcing the
receiver from the AC line reduces noise pickup from all the crud that
modern electronics dump into the line.  It was a significant difference in
my situation.  Also if you haven't already, adjust the IF transformers for
looser coupling by pulling up on the tabs.  This will reduce the noise BW.
