You can, at a pinch even go up to 12v but I wouldnt transmit with 12v. The advise is anywhere from 6v to 9v. The specs are upto 12v. The back panel?that doubles up as a heatsink can't take more heat.
Apart from the PA, the rest of the circuitry is regulated down to 9v anyway (if it exceeds 9v, that is).?
We thought of adding a heatsink to the backpanel, but it was just too bulky. One day, maybe Hans wil design a class E amplifier for the zBitx and we will be able to run 50 watts output on a future zBitx.
