Let your radio know where it is with this GPS receiver and adaptor kit. Connect the 2.5mm data jack to the data port on your compatible radio (see list below), supply 13.8v from your PSU and place the GPS unit somewhere with a clear view of the sky. This unit is very unlikely to work sitting in your shack where the sky is obstructed.

The waterproof GPS puck is supplied with a 2 meter cable and is fitted with a 3.5mm TRRS jack to make installation outdoors simple. Either drill a 12mm hole through a wall and push the jack through or very carefully lay the thin cable in a window opening, taking care not to damage the cable when the window is closed. Also included is a 5m long extension cable (connectors not waterproof) so you can route the GPS cable back to your shack desk.

The adaptor box contains a simple PCB with output connectors, power LED, 5v regulator to provide clean, stable power to the GPS unit also has two 3 pin jumpers to allow the RS-232 output RX and TX lines to be reconfigured for different radios. More compatible radios will be added as they are tested and confirmed to be working.

Available in kit form and assembled versions. All GPS units are configured and tested before shipping. If ordering a kit, the GPS puck will be tested on my workbench with a prebuilt unit.
