This display shows the current stations active on the 144.39 MHz National APRS frequency in the Washington/Baltimore area. Although the range of VHF communications is typically only a few miles up to 15 or so, the presence of the APRS digipeaters (shown here as green Stars) provide over 250 miles of coverage. This data is refreshed every 2 minutes. See one of our special event GPS trackers, typically duct-taped to the roof of a tracked vehicle.
