Hi All, >A correction... > >>I measured the Q of my coil using the Q=Fo/BW formula and based that on the >>measured RMS input current. The Q was 59.25 (146.34 / (147.61-145.14)). >> >>With an input voltage of 0.6606 RMS, I would expect the top voltage to be: >>0.6606 x 1.414 x 59.25 = 55.35 volts. >> >>The sum I measured is 69.72 volts. > >I don't trust the method I used above and I remembered my coil really has a >Q around 70. I remeasured the Q with an antenna and scope. And got a Q of >67.47. That is incredibly close to the 69.72 volts the profile test gave! > >Cheers, > > Terry Actually, if I plug the new Q into the equation above I get a voltage of 63.023. So I have a little healthy error :-)) Also, my oscilloscope is a Tektronix TDS210 not a B210. Picky tonight :-)) Cheers, Terry
