I am curious whether the Anytone AT-D878UV (which is a DMR radio) can be programmed to receive dPMR channels.

I understand that the big difference between DMR and dPMR is the technique used to divide the 12.5kHz channels into 2 6.25kHz sub-channels: DMR uses TDMA (time division) while dPMR uses FDMA (frequency division).

Is there a way to switch the radio to FDMA? Would it be enough to support dPMR channels?

I'm tempted to believe that using dual time slots (DCDM) mode might work with dPMR, since you are no longer bothering with TDMA. However, I couldn't find anything in my research. Try switching the AT-D878UV to use both time slots at the same time and test it with a dPMR radio on simplex. While it probably won't work, it's your best bet since DCDM does not rely on time synchronization, so it may just be a rebranded dPMR mode for simplex.
