I am mystified by a problem I'm having....
I have an ICOM
with built-in AIS
receiver and NMEA 2000
connection to my chart plotter (raymarine es)
This was working fine recently, but I wanted an AIS
transponder, so I started installing a Vesper Marine
AIS transponder and Vesper VHF
That 'worked' inasmuch as the indicator lights were green and tx light was flashing, but I wasn't getting AIS data to the chartplotter
through the Vesper Marine
So I disconnected the AIS transponder and VHF splitter, and went back to my original setup - but now am not receiving AIS data on the VHF, neither through NMEA
to the chart plotter nor through the integrated AIS display on the VHF unit itself.
I feared I may have damaged my antenna
somehow, but the VHF still transmits and receives voice no problem.
Any thoughts on what could be going wrong or what to try next?
