[TG] [TG11] AIS 500 fault message while transmitting on VHF

[Berwick]

Thanks for the response. Answers to some of your questions:

-The AIS does share an antenna via the splitter.
-It is the same antenna it has always been connected to- a 19' Shakespeare.
-When I bought the boat the AIS 500 was connected to an old Raymarine VHF which had the same problem.
-When I upgraded to the Axioms and ICOM, we changed out everything, but the AIS 500 unit.
-Still having the fault warnings, but only when transmitting.
-I checked the VSWR on all transmitting channels (01-88), and it is 1:1. I do not know how to check the AIS channel.
-The faults occur occasionally, and not on every transmission.
-The faults do occur when transmitting on low power as well as high power.

I will have to buy connectors to be able to hook the AIS 500 to the PC USB port on the boat. I assume that when I hook it up with the AIS software there is a diagnostics tab? Thanks for any guidance.
