Hi Walt,

Thanks for telling us about the tuning curve being upset using series
caps to reduce the tuning cap that much. I wondered if something like
that would happen but I didn't have time to run more calculations to
look for that. I have been thinking about using the series cap means of
getting the tuning range I need in a project that calls for dual 90s.
The closest I can find readily available is a dual 120 but that's a lot
closer to the desired value. I hope the series cap trick is more viable
in a case like that.

73,

Bill  KU8H
