Power amplifier is working, 100 watts out on 20m, with 2 watts drive from exciter

2 watts PEP drive from the exciter into one IRF510 pre-driver which then feeds 4 IRF510's in a push/pull configuration. With this i am able to achieve approximately 100 watts out with about 20 VDC. Will try it with a 24 VDC supply shortly.

Amazing what you can do with a bunch of IRF510 MOSFETS.....
