This is going to be great fun! But failed at the first hurdle, I've some node-red which takes a feed from port 10110, filters for just AIS & filters out some less interesting messages, calcs the distance from the boat then sends to influxdb. Works well so far with a daisy ais which never gets turned off. But now just wired up the icom gx2100 so 2 sources of AIS nmea, from just the 10110 port data can node-red tell which device it was received by? So then you could plot receivers against each other.

Guessing no but always worth an ask. Maybe the data needs to go in as sigK then get split into sources & take lat/long from there? Great fun though, will be able to test little home made antennas low level & see how they behave against a masthead Metz. So far for receive both class A & B max distances change all the time, everyone likes to parrot height is the most important variable, well it ain't the only one & maybe less of a big deal than changing local conditions.
Thought that would be easy..... so there are 2 connections to nmea0183 AIS messages coming in. i want to save as 4 measurements - ais1.classA etc. In the raw messages there seems like nothing to tell the 2 sources apart, sigK snips the 0183 comin in so the class & position are in different deltas. So how could you get just class & position? Can node-red see sigk events for data coming in over 10110? or maybe save nsmi into flow variable & compare or something??
