The load R has risen so looks valid. The BPSK message is stored in PIC so won't change in the immediate future, I was soak testing the PA and thought you'd prefer a message to a carrier. Keeps within the spirit of the licence ID rules as well. May not persue the 2.5kW full bridge PA design. I had a couple of rather frightening explosions yesterday that were a bit off-putting. NEVER, EVER EVER use a make before break switch for hot switching transformer taps , I hadn't spotted it was Mb4B. That's the trouble with having a very extensive junk box - don't tend to look at components carefully enough. But the present half bridge design will upgrade to 800W reliably with IRF462 devices -cheaper than IRF450. Still need a very fast acting OP short circuit protection circuit.
