[ARC5] 80 KHZ IF

[Robert Eleazer]

I recently augmented my collection of National receivers with an NC-300.  I previously have done quite a lot with the Cosmic Blue series of receivers, specifically the NC-155, NC-270, and NC-190, and was quite surprised to see that while the NC-300 had the same first IF as those other sets, 2215 KHZ, it has an 80 KHZ 2nd IF.

Of course I at once thought of the BC-453 and similar command sets, with its 85 KHZ IF.  I had no idea that any HF receiver used that low an IF.  How common is this?  Was the BC-453 use as Q5er the inspiration for this?
