Default BC-453 IF tuning

Yes, maximum selectivity is when the plungers are fully withdrawn. Bandwidth
is on the order of 100Hz.

I would assume that maximum selectivity occurs when the 85 kHz IF
trasformers actuators are fully pulled up (maximum distance between primary

Can any one please confirm or deny?
