Because the TC-780 is an older model, HYT (now Hytera) has archived the support pages for this device. Finding a working link can be difficult. If you are searching for a "new" download link, you must be cautious.
⚠️ Important Warning:
Many websites claiming to offer free radio software downloads are laden with malware or spammy "survey" locks. Before downloading any file, check the file extension. The legitimate software usually comes in a compressed .rar or .zip file, and the installer should be an .exe file.
Yes. Read from the master radio, save the codeplug as master.hyt. Then disconnect the master, connect the target radio, and click Write to Radio using the saved file. This is much faster than manual entry.
Since HYT is now Hytera, the official source is the Hytera Partner Portal. You will need to register as a dealer or end-user (free registration is often available).
Due to copyright and safety concerns, we do not host direct download links. However, here are the three legitimate methods to obtain the newest software version.
Yes, the Customer Programming Software (CPS) is provided free of charge by Hytera/HYT for legitimate owners. You should never pay for the software itself, only for the programming cable.
Even with the newest CPS, you may encounter errors. Here are the top fixes.
| Error Message | Cause | Solution |
| :--- | :--- | :--- |
| "Communication Timeout" | Wrong COM port or radio not in programming mode. | Ensure radio is ON when cable is connected. Re-check COM port in Device Manager. |
| "Model Mismatch" | You are using software for a different HYT model. | Download the correct TC780 CPS. Do not use TC700 or TC800 software. |
| "Checksum Error" | Corrupted codeplug or faulty cable. | Re-read the radio. If persists, try a different USB cable or port. |
| "Out of Range" | You programmed a frequency outside the radio’s band split. | The TC780 comes in VHF (136-174 MHz) and UHF (400-470 MHz or 450-520 MHz). Verify your radio’s band label. |
| Software Crashes on Launch | Incomplete installation or missing Visual C++ runtimes. | Install latest vcredist_x86.exe from Microsoft. Reinstall CPS as Admin. |
Assuming you have obtained legal CPS and a working cable, the general steps are:
Communities like RadioReference.com or Communications Support UK sometimes have verified file repositories. If you use these, always scan the downloaded .exe or .zip file with Windows Defender or Malwarebytes. Look for threads with high user ratings and "New Version" in the title.
What to avoid: "Free download" sites that require you to complete surveys, download "download managers," or pay for a membership. The HYT TC780 software is free to distribute from legitimate sources.
