Ok, so I did the IRF520 conversion (with companion parts) and the results are poor. Im getting 1.5w DK ~4.5W peak swing (pep) I tried diagnosing the problem, using another 520, and checking values at various points. I did find that the gate voltage is sitting at .2 volts, with modulation (whistle) it hits .33 volts. From what I understand this should be around 3.5volts correct? All pots are tuned for max output (L14,L17,L18) I also switched the driver to a 2314 and output decreased. So, can/where can I grab a TX only voltage to feed the gate with proper voltage? Any help would be greatly appreciated... I know this thing should be outputting more. I started this project to learn the workings of RF amps, and have learned a lot, but Im at a halt.
