SGTC and IDR-Tuning

Previous post was incorrect in regards to tuning.
You tap all primary turns into tank which sets system
to lowest frequency, with the IDR elevated a fair
distance (4"-5") axially away from primary.  Adjust
the IDR downward toward the primary.  As the
IDR plate approaches the primary, Lp will decrease
due to magnetic flux loading, which will increase the
tank frequency.  Adjust until primary and resonator
are tuned appropriately. Sorry for confusion... :^?
