Potential AIS OpenCPN conflicts

[jimcreed]

I use a PC(OpenCPN ) at the nav station as a full back up system, but Raymarine as a full system at the helm.
I am considering adding an AIS transceiver to the Raymarine (SeaTalk) system.

Since I already have an my old AIS receiver in the back up VHF/GPS
system. OpenCPN can report AIS boats now.

Can anyone tell me what will happen when the Raymarine transceiver sends out the AIS signal on its antenna and then that AIS signal would be received on the VHF/OpenCPN circuit.

Is OpenCPN going to report that I am in constantly in a collision status with
another boat? When that boat is effectively my boat.

Do any of the systems have a "block Messages From" from certain MMSI numbers?

I know I can eliminate the AIS receiver but that defeats the redundancy aspect of the system.

On another note:

Could a list of say 20 MMSI numbers be excluded from reporting. Or a list of 290 MMSI be only reported. Like when traveling with a fleet of boats from a club all going in the same direction
