[ARC5] Can yoiu say...

[Robert Eleazer]

Building a BFO for that GE multiband receiver was one of my very first ham radio projects.  I found a circuit for a BFO using a single PNP transistor and 455 KHZ IF coil in an old issue of 73 Magazine and tried building it using Radio Shack parts.  Did not work, so I called my Mom and asked her to mail me a big old NOS Millen IF transformer I picked up when the university threw some stuff out.  It worked!  What an accomplishment!

Then I found out about selectivity.  That GE covers 160 KHZ to 18 MHZ plus the FM band - and a ham band was about 1/2 inch wide or less. I managed to tune in SSB with it just once.   I still have that radio and was tickled when last year one showed up on that TV show "The AmeriCans" being used by spies to receive Soviet messages.

I next bought an assortment of tube type IF coils from Meshna and made a few more oscillators.  I need to find where I put those because I need them to install in a GRC-9 receiver that is missing some.
