[ARC5] BC-453 (or R-23) in AM reception.

[Geoff]

I have used a BC-453 for AM in the 50's and again during the past decade; 
both times with a HQ-129X as the front end.

At minimum selectivity AM audio is about 2kc and only one sideband when 
tuned but sounds no worse than a SS rig with a narrow SSB filter. It has 
mostly been used on the ham bands.
Ive used a succession of  TS-930, TS-940, and TS-950SD with narrow filters 
for BCB DXing since the 80's.
