Hmm. MarineTraffic is showing lots of boats on Back Creek and in Selby Bay. Chesapeake Harbour should show up.
I went back a week on aprs.fi but didn't see you there either.
AIS is on VHF channels 87B and 88B. Have you tried listening for your own transmission?
If those simple things don't work you'll have to start looking at your installation. I live in Eastport off Harness Creek. Let me know if I can help.
Thanks. My system was professionally installed; I hope it's not an installation problem. There is a boat called Bernadette that has her AIS on 24/7 in Chesapeake Harbour. I don't see her on either website. Perhaps it is just a dead spot. I plan to go for a sail on Sunday. I guess I'll just have to try calling a few AIS targets and ask if they can see me.
How would I go about listening to my transmission? How would I be able to tell it's my data?
