Yeah, it should be working fine. The radio is not on right now though. I'm definitely seeing other stations on the Garmin's screen, and my radio is in "BCON" mode, which should mean I'm sending out position reports every five minutes. *did* set the proximity limit to 20 miles, but that shouldn't affect who sees me, just who I see plotted on my Garmin, right?
Give me a call, Chris, and we can coordinate some testing tonight if you want.
