This is the coil I built for my brother.
TCBOR/RQ Static Gap Construction
The 3/4" copper electrodes have been tapped and the fan mount completed.
Drilling the holes for the electrodes and milling slots for air to escape.
The unit is complete and ready to go!
Secondary Measurements and Calculations
Scope, signal generator, frequency counter, and antenna set up to measure the unloaded resonant frequency of the secondary coil. Secondary is being base driven from signal generator and the signal is being picked up via a 1-foot antenna hanging from a 10x probe.
The unloaded Frequency measured 1.018mhz.
The loaded frequency (with a 10.5" x 4" Toroid) measures 582khz.
