Wouldn't that mean a PL-259 antenna connection on the chartplotter? To (most likely) an external splitter?? Coupled with the RF issues somehow I don't think any chartplotter manufacturer will be going down that path soon.
Perhaps we can agree to disagree, but to my mind, the only sensible place for an AIS receiver to be integrated is within the radio - VHF+DSC/GPS/AIS together with a single data stream to a non-GPS chartplotter or VHF+DSC/AIS with a data stream to/from a GPS-enabled chartplotter.
Having DSC on the radio is obvious, but having AIS on the VHF, even without GPS, allows push-button "target calling" - not something you can do from a chartplotter.
