Where in MD are you?
Marine Traffic did pick me up once while going under the Chesapeake Bay Bridge, so I think I'm transmitting. My slip is in Chesapeake Harbour near Annapolis. Perhaps the base station listed on the proAIS2 target list was not a Marine Traffic base station, but aren't there any others near Annapolis? At what sort of range should I be visible with my Raymarine AIS650? I would think I would be showing up much more often.
