[ARC5] Receiver Filter Adaptor

[kgordon2006 at frontier.com]

Well, David, et al. Your musings are well taken here.

Now, considering a simple method of increasing selectivity in our BAs, we 
might take a look at Mike Murphy's WU2D youtube video "ARC-5 
Command Receivers Part-4" on selectivity.

Near the end of this video, Mike shows how he improved the selectivity of a 
BC-455 by modifying the first IF transformer into a crystal filter.

His solution was very simple, and all of it fit inside the ARC-5 IF can.

He (like me) apparently also believes in and uses the KISS principle. ;-)
