Does the ST32DVM board support FM mode?

I put together another repeater with the ST32DVM board and two mobile radios.
As of now, the repeater is configured DMR only.

I noticed there is support for FM analog mode in pistar expert settings.

Does the ST32DVM board support this mode directly?

If so, what do I need to do to enable the mode?

Tnx

The limitation in the STM32 will be the firmware it can run. It would require a firmware that can support FM mode.

A hotspot can not do FM the AD7021 RF chip(s) used in a hotspot isnt capable of FM.

MMDVM Repeater boards that run external rf decks can do FM. (firmware dependant)

TNX for the reply.
The ST32DVM board is connected to two Motorola CM200's running full duplex mode. So FM mode should work. Repeater identifies every 10 minutes.

I'm also using a cable assembly made by the same company that makes the ST32DVM board. I will email them and see if they have any suggestions

Was able to get the FM option to work only after upgrading the firmware of the ST32DVM board.

Now to figure out what all the settings mean and what they do lol!
tnx
