[ARC5] 6-9.1 MHz receiver IFTs

[Kenneth G. Gordon]

After spending quite a bit of time trying to determine which IFTs go with 
what receiver, and ending up with a list which at this time I can assure 
you all is not complete, I find the following concerning the subject 
IFTs:

Those IFT's labled with the numbers 7277, 7278, and 7279, for the 1st, 
2nd, and 3rd IF respectively, are generally for the BC-455, and are the 
"single coil" types. I.e., one coil, the top one, is a pie-wound type 
while the "other" coil is simply a single-layer solenoid type.

Those IFTs labled with the numbers 9693, 9697, and 9699, for the 1st, 2nd 
and 3rd IF transformers respectively, are the "standards". I.e.the two-
pie-wound coil type, and appear to be used in the R-27/ARC-5 receivers. 

The coils can be moved like the 3-4 MHz IFT coils can be for greater 
selectivity.
