Goodspeed's CAT Tool

This is the source code for an Android app for programming the Kenwood TH-D74, TH-D72, and TM-D710. Based on CodePlugTool, a pure-Java library and command line tool for controlling these same radios.

If you'd rather just install the app, it's available for free as Goodspeed's CAT Tool in the Play Store.

Status

The app is now functional for editing radio memories, including uploading to and downloading from a radio over Bluetooth and TCP, as well as importing and exporting a CSV format compatible with CHIRP.

Usage

Open the app, then poke around. I'll update these instructions when things are more stable.

To share a mobile radio's serial port over your home network, first set the baud with stty and then open the socket with socat. This is the script that I use in my shack.

stty -F /dev/ttyS1 57600
socat tcp-l:54321,reuseaddr,fork file:/dev/ttyS1,nonblock,raw,echo=0

For Bluetooth, first pair your phone with the radio in Android's Settings, then select the radio in the app's own Settings. The TH-D74 is known to work without additional hardware, but other radios should work with the right adapter.

Building

This code depends upon CodePlugTool.jar, which must be built using JDK8 or the Android SDK's javac, then placed in app/libs/. For your convenience, a rarely updated build of that library is included in app/libs/.

To build the main application, use Android Studio 4 and a matching build of Gradle.

Development

At home, I develop the app in the AVD emulator with the app configured to use my Kenwood TM-D710 over TCP. At the coffee house and the bar, I debug the app on my phone and connect it to my Kenwood TH-D74 over Bluetooth to avoid cables.

Any radio protocol changes are written separately in the CodePlugTool repo and tested in Unix before ever seeing the phone. If a feature doesn't exist in the command-line JAR file, that's a bug and should be fixed there rather than debugged here.

License

If you use this app, you owe Travis Goodspeed (KK4VCZ) one India Pale Ale. It would be nice if it were delivered cold at a RACK meeting.
