Custom-built GPS-disciplined Clock or a GPS Data Display, for ham radio.

• LCD Screen: The large rectangular window is a display for showing data like GPS coordinates, UTC time, grid squares or satellite signal strength.

• SMA Connector (Labeled "GPS"): This is a standard radio frequency (RF) connector where you would screw in an external GPS antenna.

• 13.8V Power Input

• Rotary Encoder/Potentiometer

• Internal Hardware: Based on the size, it almost certainly houses an Arduino, Raspberry Pi Pico, or ESP32 microcontroller paired with a small GPS module (like a NEO-6M or NEO-M8N). Cannot confirm which since this is part of an estate liquidation.
