Hello, list
I finally decided to measure the Q of my coil. I have a measured DC resistance
of 26.7 ohms. According to E-T5, my coil's operating frequency is about
125kHz. The inductance is calculated to be 33mH by WinTesla. Putting this
into
the equations gives me a Q of 970!
This number seems about 5 times too high, and my primary tuning isn't terribly
finicky. Is this high of a Q possible?
Thanks,
Mark B.
