TIDRADIO TD-H9.
Bluetooth programmer.
H9 Toolbox connects to your TIDRADIO TD-H9 over Bluetooth so you can edit channels and radio settings in Chrome or Edge. Import and export channel CSV files, transfer readable JSON configurations, and save a full .img backup. No account is required. Radio data stays in your browser; visits and site interactions on h9toolbox.com are measured with Google Analytics.
TD-H9 owners have successfully used H9 Toolbox on several radios.
Connect to your TD-H9
Turn on the radio’s Bluetooth programming mode, then choose it from the browser’s device list.
Bluetooth options
The browser can only inspect services listed before you choose a device. If your radio uses another service, enter its UUID and reconnect.
Read & back up
Read the radio before editing. Saving an untouched backup is recommended so you can recover your original configuration.
No radio image loaded.
Channels
Create, edit, and remove memory channels. Changes stay in the image until you write them to the radio.
CSV includes every editable channel option. Import merges by channel number; Replace all also clears occupied slots missing from the file after confirmation. Older channel JSON exports can still be opened.

| Read from the radio or open a backup to see channels. | ||||||||
Edit channel
Changing RX updates TX for simplex or a recognized repeater output. Select + or − when needed; enter TX yourself for a custom split or leave it blank for receive-only.
Radio settings
Inspect and edit documented radio, Bluetooth, GNSS, and APRS options from the full backup. Open a group to see its controls. Unknown values remain unchanged unless you select a new value.
Fixed GNSS coordinates, stored DTMF codes, FM broadcast presets, and undocumented firmware bytes remain in the backup and are not edited here. Changing APRS beacon or relay options can cause transmissions; review those values before writing.
Write changes
Only changed 32-byte blocks are sent. Before each write, the app checks that the radio still matches the original image, then reads the block back.
About programming the TIDRADIO TD-H9
Which browsers support Bluetooth programming?
Use Chrome or Edge on a computer with Bluetooth and open this site over HTTPS. Enable Bluetooth programming mode on the TD-H9 before connecting. Web Bluetooth is not supported in iPhone Safari.
Can I edit channels without connecting a radio?
Yes. Open a previously saved TD-H9 .img backup or a lossless JSON archive to work offline. You can edit channels and mapped settings, import or export channel CSV files, and download the working .img. Writing changes to a radio requires a Bluetooth connection.
Which channel settings can I change?
Edit receive and transmit frequencies, channel names, FM or AM modulation, bandwidth, CTCSS and DCS tones, transmit power, scan inclusion, and other mapped channel options for channels 1–199. The radio settings editor also covers mapped display, button, Bluetooth, GNSS, and APRS options. Undocumented bytes are preserved.
Do I need an account, and where is my radio data stored?
No account or ODmaster login is needed. Radio images, channels, and settings stay in browser memory unless you download them. Google Analytics measures visits and site interactions on h9toolbox.com, but does not receive radio images, channels, or settings.
Should I save a backup before writing changes?
Yes. Keep an untouched .img backup so you can return to your original configuration. Review your channels and settings before writing. H9 Toolbox checks the radio against the original image, writes only changed blocks, and reads each changed block back to verify it.
