[ARC5] Command Set Commonality

[Robert Eleazer]

I dug out Gordon's "Command Sets for All Frequencies" article in the Jan 67 issue of CQ to check on commonality for the sets.  Just as I thought, here is what it shows for the C4, the tuning cap.

190-550 and 520-1,500 use the same tuning cap, max 346 pf.

1.5-3.0 and 3-6 use the same tuning cap, max of 147 pf

6-9.1, 9-13.5, and 13.5-20 use the same tuning cap, max of 62 pf.

20-27 uses a max 41 pf tuning cap.

So, with the pluggable IF's, pluggable RF's and easily removable BFO coils they could cover all the production models as well as most of the special ones with just 3 tuning caps.   Darned clever!
