[ARC5] BC-454-A, etc. Selectivity option found?

[Kenneth G. Gordon]

Here's another one:

BC-454 ---> BC-946 connected to output of last IF transformer of BC-454 tuned to 1415 
Khz,---> followed by BC-453 connected to output of last IF transformer of BC-946, and tuned 
to 239 KHz.---> 85 KHz to detector.

Triple-conversion.
