Hyt Tc-320 | Programming Software

HYT TC-320 radios are legendary in the retail and hospitality worlds for being "tank-like" but tiny. However, their custom programming software (HT320E) is often the source of both frustration and ultimate triumph for radio enthusiasts.

Here is the "solid story" of how a typical setup goes, from the cable struggle to the final "chirp." The Mission

You have a fleet of TC-320s. Out of the box, they might not talk to your existing radios, or they have that annoying "battery low" alert every 30 seconds. You need to change the frequencies, set the PL tones (CTCSS), and maybe unlock the high-power setting. The Equipment The Radio: A sleek, palm-sized HYT TC-320.

The Cable: Not a standard USB. It looks like a mini-USB, but it has a proprietary pinout. Using a standard phone cable won't work and can sometimes trip the radio's circuit.

The Software: HYT HT320E (Programming Software). It looks like it was designed for Windows 98, but it gets the job done. The Process

Driver Russian Roulette: You plug in the USB-to-Serial cable. Windows 11 screams. You spend 20 minutes hunting for a legacy Prolific or FTDI driver because the modern ones block "clone" chips.

The Handshake: You open the software, select "COM 3" (or whatever port your PC guessed), and hit Read from Radio. hyt tc-320 programming software

The "Ah-ha" Moment: The screen populates. You see the 16 channels. You realize the previous owner had them set to some obscure business band or, worse, high-interference FRS channels. The Tweaks: You punch in your clean frequencies. You set the Squelch Level to 3 (the sweet spot).

You disable the VOX because nobody wants to hear your heavy breathing over the air.

The Write: You click Write to Radio. The status bar crawls. The LED on the radio flashes red and green like a tiny Christmas tree. The Result

The radio emits a sharp, confident beep. You test it against a second unit. The audio is crisp. You’ve just turned a

dollar piece of plastic into a professional-grade communication tool.

💡 Key Takeaway: The software is finicky, but once you get the correct USB driver, the TC-320 is one of the easiest radios to customize.

Technical Analysis and Operational Guide for the HYT TC-320 Programming Software

Abstract: The HYT TC-320 is a compact, budget-friendly UHF two-way radio widely used in hospitality, construction, and security. However, its proprietary programming software (often labeled TC-320_Software.zip or HYT TC320 CPS) is notoriously difficult to source, install, and configure on modern operating systems (Windows 10/11). This paper provides a definitive guide to identifying, installing, and operating the programming software, troubleshooting driver conflicts, and preserving radio configuration data.

Step 5: Write to the Radio

  1. Double-check all entries. Mistakes can cause interference or illegal transmissions.
  2. Click Program > Write (or F3).
  3. Wait for the "Write Successful" prompt.
  4. Disconnect the cable, turn radio off and on, and test channels.

Step-by-Step Guide to Program the TC-320

  1. Install the Cable Driver

    • Install the driver for the programming cable (usually Prolific PL-2303 or similar).
    • After connecting the cable, verify the COM port number in Windows Device Manager under “Ports (COM & LPT).”

  2. Install and Run the HYT CPS

    • Install the software (right-click installer → Run as Administrator if needed).
    • Open the software. If you see a blank screen or menu issues, try setting Windows to Run as Administrator and enable Windows XP SP3 compatibility mode.

  3. Connect the Radio

    • Turn the TC-320 ON (volume at middle level).
    • Plug the 2-pin end into the radio’s side jack (usually the larger speaker/mic port).
    • Connect the USB end to your PC.

  4. Select the Correct COM Port

    • In the software, go to Program → Communication Port (or similar). Choose the COM port seen in Device Manager.

  5. Read Data from Radio

    • Click Program → Read Data (or press F4).
    • If successful, the current radio settings will load. If it fails, check COM port, cable connection, and driver.

  6. Edit Settings

    • Use the channel table to enter frequencies (must be within UHF range: usually 400–470 MHz).
    • Add CTCSS/DCS values if needed.
    • Set channel names (limited characters, often 6–8).

  7. Write to Radio

    • Click Program → Write Data (or F5).
    • Wait for the “Write successful” message. Do not disconnect the cable during this process.

Alternatives to the Official HYT Software
