Ahh that might be easier....

if they are both ambe could you set it like this ysf guide?

or do you need the 2 mmdvm bridges?

No,
Both DMR and NXDN are AMBE. No transcoder needed.

follow up question/direction would a NXDN to DMR bridge pretty much the same setup as that?

It's going to require a transcoder.

P25Reflector and NXDNReflector are external to the bridge. Consider them endpoints.
MMDVM_Bridge_a and MMDVM_Bridge_b are a single instance of MMDVM_Bridge.
Analog_Bridge_P25 and Analog_Bridge_NXDN are each a single instance.

Has anyone done a P25<>NXDN bridge? If so I'm looking for some guidance/instructions on how.
