Kenwood TH-D72 - Appalachian Trail Golden Packet Configuration


While it is possible to use programming software such as Kenwood MCP-4A or RT Systems KRS-D72 to apply the configuration settings listed below, we encourage you to program the settings via the front-panel keypad. While the process is tedious, it is important to ensure you are able to configure your radio in the field without a computer at your disposal.

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

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

VFO B: 445.925 MHz - Voice communications with adjacent stations

  • DO NOT USE THE STANDARD APRS frequency 144.390 MHz for AT Golden Packet!

Firmware Update

Update your radio's firmware with the most current version available on the Kenwood support site:

Kenwood - Amateur Radio Products Software Downloads - (

The most current version for the Kenwood TH-D72A as of the time this document was posted is: 1.10 (released August 2020)

Configuration Backup and Factory Reset

Prior to configuring your radio, make a backup of the configuration and perform a factory reset. This will ensure that you start with the factory default configuration as your baseline.

The easiest method of backing up the configuration is with Kenwood MCP-4A or RT Systems KRS-D72.

Once you have a good backup, proceed to performing a factory reset.

There are two methods to perform a factory reset:

Option 1

  1. Turn the tranceiver power off
  2. Press [F] + Power On
  3. Use the Up/Down arrows or rotate the Tuning control until "Full Reset" is selected
  4. Press > OK to set the reset type
  5. Press > OK again to perform the reset

Option 2

  1. Navigate to Menu 199
  2. Choose FULL RESET from the menu

Auto PM Store - WARNING

Bob used to be emphatic about disabiling Auto PM Store however, if used properly, it can an will work to your advantage!

Spend some time learning how it works.

Takes a snapshot of the state of the currently selected PM when radio is powered OFF.

Start with Clean Slate at Power On ONCE you have the specific PM fully configured.

Field Operations

Once out in the field, the recommended method involves:

  1. Tune the radio on VFO A to 144.340 MHz - Set the power level on VFO A to High (if your battery has sufficient power) - otherwise, use Medium power
  2. Tune the radio on VFO B to 444.925 MHz - Use minimum power for voice operations
  3. Press the TNC button until D and APRS12 are displayed on the top line of the display
  4. Press the BCON button until BCON is also displayed on the top line of the display.


It's absoltuely critical that you test your configuration multiple times BEFORE going out the day of the event. We do not want you worrying about troubleshooting issues when you arrive the day of the event. Now is the time to ensure everything works as expected.


If you have ANY questions, do not hesitate to reach out to the ATGP group on for futher assistance! It's imperative to ensure your radio is configured correctly and is consistent with how others have their radios configured.
