They say the only stupid question is the unasked question, so I am going to ask one. I believe I know the answer, but here goes anyway. Will a PCM receiver work with an FM transmitter both on the same frequency with negative shift? Thanks in advance, folks.

Some computer radios can be set for PCM or PPM (what you're calling FM but pcm is a form of FM too)

A regular radio thats not PCM or programmable, then no.

One other detail to consider with a PCM receiver, it must be the same brand as the transmitter, all PCM systems are brand proprietary.
Good luck,

I had a Futaba Conquest PCM non-computer radio. It only worked with Futaba PCM receivers. I also had Futaba PPM only radios that would not work with Futaba PCM receivers.

When I bought my first Futaba T6XA, computer radio, it was PPM/PCM switchable, but Futaba had not come out with newer PCM receivers, so I was stuck with PPM. Futaba then came out with 8ch PCM receivers and even sold the T6XA with either a PPM or PCM receiver. Since then, all Futaba computer radios are PPM/PCM switchable, but a Tx set to PCM does not work with a PPM receiver, and vice versa. I have used a mix of PCM and PPM receivers and each model memory on the Tx allows you to set the default for PPM or PCM.

If you do not have a PCM capable TX, the receiver will not work, and it has to be the same brand to work for PCM.
