Not possible, unfortunately.
IIRC The PRUs run at 200MHz. I'm not an expert at signal magic, but unless somebody has a really smart trick up their sleeve, it means you can synthesize at most a 100MHz signal (assuming changing the state of an output takes only one cycle, which I believe it does).
- squarefoot 10y agoAh sorry, I didn't mean producing the radio frequency signal but the modulating one which would be paired with a carrier generated by a separate module. Admittedly I know next to nothing about digital modes so I have no idea if the PRU could stand the necessary bandwidth to do such a thing.
