I suppose the logic is more in line with reality. Truth is increased
loading means less C, so it stands to reason that higher numbers stand for
increased loading. Makes sense to me. However since increased loading is
less
C and less loading is more C is confusing. Seems that is the way the
MFG'ers set up the dials and as they call for it in the loading instructions.
If the instructions called for decrease the C value to add loading that
could be confusing even more if one didn't know that increased loading is
less C. As we move closer to SS amps this issue would be like discussing dial
telephones. Talk to a young teenager ask them about dial telephones. Ha

Actually Ten Tec has the better idea for those operators not used to the
other way. With 0 being minimum C and 10 the max you dont have inverted

during a contest.
I never could understand why increased loading went with a higher number
when less C on the Tune cap is the opposite. And without a standard there
is
always the chance for error and damage.
Yes, I understand that the higher number is supposed to convey higher
loading and trying to tell a new user that higher means less might result
in
glassy eyes and brain fades.
