Kenwood TH-D74A - Appalachian Trail Golden Packet Configuration

Note

The Kenwood TH-D74A APRS functionality does not include support for digipeating. As such, it is ONLY well-suited for the Appalachian Trail Golden Packet event if it is used at an end station. The only two locations where use of the TH-D74A would be permissible would be KATHDN or SPRNGR.

Moreover, when taking into account that its power output is limited to 5-watts maximum it can only be used at KATHDN.

If you are interested in using the TH-D74A, please discuss it with the coordinators of the event.

PLACEHOLDER

Once your radio is configured, the end result will allow you to operate as follows:

VFO A: 144.340 MHz - APRS enabled (Appalachian Trail Golden Packet APRS frequency*)

VFO B: 445.925 MHz (Tone 100 Hz) - Voice communications with adjacent stations

* NOTE: DO NOT USE THE STANDARD APRS frequency 144.390 MHz for Appalachian Trail Golden Packet!
