Every DockTalk receiver in the United States, numbered in the order it came online. Each one is a small radio box at a home, marina, or club, listening to marine VHF around the clock.
Pins show the area, never the exact spot. Where stations sit close together, a thin line points each pin to its area.
A DockTalk station is a small box and an antenna. Host one and your harbor goes live in the app.
