Hello. I have a question, is it possible to implement broadcasting on several frequencies at the same time?

markondej commented 2 years ago

In theory, assuming cruccial source code modifications, its possible to use PCM as DREQ source for DMA engine, so it may be possible to broadcast on two frequencies simultaneously as there are two general purpose clock sources on RPi. But this is theory, requiring rewriting transmitter core.
