Well, Mike is most certainly the expert on these sorts of matters. I was 
guessing on the basis of a list I made of up IF transformers for the BC/ARC-5 
receivers. The only one that ends in 98 is the first 85 KHz IF for the BC-453 
and the R-23/ARC-5. But that is 4698.

I said second in my earlier e-mail, but I meant first IF.

Good. Well, you have the accurate data then.
