Pete -
Thanks for the procedure.
All -
Interesting I was applying this procedure outlined to the Low band
still cannot get enough capacitance out of the circuit using the
corrector at the low end calibration points.
The Low end coil had several cracks in the bees wax covering. Printed
spec for the Coil is 7.06 mH measure 7.27 mH out of circuit. The
temporary removal of the temperature compensating coil did not change
the value by much .
Suspected reasons for the increased L :
Moisture may have seeped in to the windings through the cracks in the
Bees Wax coating causing increased L.
Bees Wax covering has changed consistency causing increased L.
Suggested corrective action?
Remove the Bees Wax coating ?
Any suggestions
Thanks
Hutch
