Thanks for the feedback! I built the CW system to test out power magnification. I was also going to use the CW as a carrier signal and possibly integrate logic into the signal going on/off to make a binary communication system between Tx and Rx.

The above experiments are very interesting, I will likely test this schematic with my CW setup and see if there are differences in power in primary, secondary and return circuits with adjustments to size of torroid and height of torroid in return circuit.

Thanks again!
