Hi Steve, I try to use full range variable caps whenever possible. Padding
both C tune and C load variables does work, however I have noticed that
given the same capacitance either way changes things. What I mean is, take a
150UUF variable C tune cap and say 250UUF is needed. You pad it with 100UUF
of
lump capacitance. On the other hand you take a full range 250UUF variable
cap. When each is put in a circuit they will behave in a slightly different
manner since each will have a different Xc value though the C value is the
same.
I have noticed this in my building and so when I do a tank circuit I notice
things change if I use a full range C versus a padded C variable. Lou
