[HBR] Westinghouse receiver thoughts

Well, I thank the folks who looked this up for me
looks like a lot of info can be found on the internet : )
Was surprised this was found as fast as it was...

Also looks like the IF cans are not very useful for the
HBR design, but it was still well worth the ten bucks.

For those not familiar with the Westinghouse receiver
it is an AM/FM receiver, with 455 and 10.7 side by side
within the same IF cans.

I did have a question tho, and that is if you used these
cans in a receiver and you were using the 455kc part,
would the 10.7 part have any effect on the 455?  What
about keeping that circuit open, or shorting it???

Another question to show my ignorance in the subject
has to do with bandwidth.  IF you were to use this 10.7
in a receiver for Ham band activities, how would you
change (or do you need to change) the IF's bandwidth???
I remember picking up 2 meters on an AM rig with 'slope'
detection, but the received audio was very week. Would
not the narrow band FM also be VERY week using a
wide band FM IF setup?

I know I saved some old scanners to use for possible IFs
and audio outputs, just build the converter/receiver in front
of the rest of that circuitry, but have any of you done the
same with an FM broadcast receiver such as this
Westinghouse???  Just day dreaming I guess : )

OK, I guess enough of the off topic subject fer now.
