[Milsurplus] RU coil G substitute or ?

[George Babits]

According to my limited notes, the "G" range was not supplied as single 
coil.  It was included on two of the dual range coils:  CW-47102, Q & G 
ranges; and CW-47203, F & G ranges

The RU coil G for 3000 - 4525 kHz seems to be not so easily found, at least 
in my stock. I think all the receivers i sold singly over the last few 
years,
i must have supplied with one G coil.

I wonder about the H coil. 4000 - 6000 kHz. You could "maybe" pad this down 
to 3700 or so, without too much trouble. But - i  think maybe the
oscillator stage, which operates at ½ f, might not track correctly? Making 
CW operation problematical ?
What think?

I still think the best approach, if you want to use this set on AM, is to 
use it at LF, and with a single MOSFET converter from 80M down to LF.
You then have 3 tuned circuits at LF, selectivity on the scale of a beginner 
radio like the S-38, but a lot more usable on HF.
