Full House with Data ...I've made a try to burn the choke with my PA and 250W
noninductive dummy load (with some pauses).KEY Down on CW and 175 volts p/p on
Tektronix osci.
That is 612 watts on the peaks....The core and windings were cold as before
the test ...I know the real test is up on the feedpoint of the antenna....
You did not get power correctly :) P=Vrms^2/R, so if you have Vpp=175V (peak to peak), Vmax=Vpp/2=87.5V and Vrms=Vmax/sqrt2=87.5/1.41=62V and P=77W on 50ohm load
