FTH-2008 Web Programmer

A web-based programming interface for the Yaesu FTH-2008/2009/7008/7009 series of handheld transceivers, using the Web Serial API.

Overview

This tool allows you to connect to your FTH-200X/FTH-700X series radio via a serial port adapter and read/write its configuration using a modern web browser. The application is completely client-side, without dependencies.

Requirements

• A modern web browser that supports the Web Serial API (Chrome, Edge, or Opera)

• A RS232 USB-to-serial adapter with a programming cable suitable for your radio model

  • If are unable to find the right cable, you can build it yourself:

    

• The FTH-2008, FTH-2009, FTH-7008, or FTH-7009 handheld transceiver

Usage

1. Connect your radio to your computer using a serial adapter
2. Open the application in a supported browser
3. Click "Connect to Serial" and select your serial port
4. Put your radio in clone mode according to the radio's manual
5. Use the "Read from Radio" button to retrieve the current configuration
   • When prompted, press PTT button ONCE to start data transfer
6. Edit the configuration as needed
7. Use the "Write to Radio" button to send the updated configuration
   • When prompted, press and HOLD the RES/MON button until display shows "LOAd"
8. Alternatively, you can use the "Read from File" and "Write to File" buttons to load/save configurations from/to your local filesystem

Important Notes:

• DO NOT WRITE FILES THAT ARE NOT BASED ON YOUR PREVIOUSLY READ CONFIGURATION FILES. Some unit-specific parameters are factory-written and may not be compatible with other units. Before saving a new configuration, make sure it was edited from a configuration coming from the same unit.
• You must successfully connect to the serial interface before you can write to the radio
• Both Read and Write buttons are disabled when there's no active serial connection
• The radio only works with a baud rate of 9600, mind this when selecting your serial interface

• Microsoft Edge (version 89+)
• Opera (version 76+)

It is not supported in Firefox or Safari.
