Can you imagine what the BC-375 would have looked like if the same guys that
designed the Command Sets had designed it?  It would have fit in your
pocket!




Subject: [ARC5] Command Set Commonality

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!
