The software allows you to customize several operational parameters: TC-320 Business Two-way Radio - HYT - Hytera
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 This is a technical guide and research paper
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.
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. If you are trying to do this right now, let me know: Do you already have the programming cable? Which Windows version are you running?
Are you getting a specific error message (like "Check Connection")?
The HYT TC-320 is one of the most popular compact business radios on the market, prized for its pocket-sized design and surprisingly rugged build. However, to truly get the most out of these units—especially if you need to match them to an existing fleet—you’ll need to move beyond the factory presets.
This guide covers everything you need to know about the HYT TC-320 programming software, the hardware required, and the step-by-step process to get your radios configured. Why Use Programming Software for the TC-320?
While the TC-320 is "plug-and-play" out of the box with 16 pre-set channels, using the dedicated Customer Programming Software (CPS) allows you to:
Assign Specific Frequencies: Match the radio to your FCC-licensed frequencies or existing walkie-talkies.
Set Privacy Codes (CTCSS/DCS): Eliminate "chatter" from other nearby businesses on the same frequency.
Customize Buttons: Program the side keys for functions like "Monitor" or "Scan."
Adjust VOX Sensitivity: Enable hands-free communication without needing to press the PTT button.
Battery Saver Settings: Tweak power consumption to extend your shift life. Prerequisites: What You’ll Need
Before you start, ensure you have these three essential components:
The Software: You need the HYT HT320 CPS. It is a Windows-based application. Note that newer versions are generally backward compatible with older radio firmware.
The Programming Cable: The TC-320 is unique because it uses a Mini-USB port for both charging and programming. However, not every Mini-USB cable works. You typically need a cable with a built-in USB-to-Serial converter (UART) specifically designed for HYT radios to ensure the PC recognizes the device.
USB Drivers: If your computer doesn't automatically recognize the cable, you’ll need to install the Prolific or FTDI drivers (depending on your cable’s chipset). Step-by-Step Programming Guide 1. Setup and Connection Install the HYT TC-320 software on your Windows PC.
Connect the programming cable to a USB port on your computer. Plug the Mini-USB end into the side of the TC-320. Turn the radio on and set the volume to about 50%. 2. Identify the COM Port
Right-click "This PC" or "My Computer" and select Device Manager. Interface Overview: The TC-320 software displays a table
Look under Ports (COM & LPT) to see which port is assigned to your cable (e.g., COM3).
In the HYT software, go to Setup > Communication Port and select the matching COM number. 3. Read the Current Data
Always "Read" the radio before making changes. Click the "Read from Radio" icon.
This pulls the current frequency map and settings into the software. Save this file as a backup before you edit anything. 4. Editing Frequencies and Features
Channel Information: Here you can enter the RX (Receive) and TX (Transmit) frequencies.
Decode/Encode: Enter your CTCSS or DCS tones here to keep your conversations private.
Scan List: Choose which channels the radio should cycle through when the scan function is activated.
Common Settings: Adjust the Squelch level (usually set to 3 or 5) and the Time-Out Timer (TOT) to prevent accidental long transmissions. 5. Writing to the Radio
Once you are happy with the changes, click the "Write to Radio" icon.
A progress bar will appear. Do not unplug the cable or turn off the radio during this process, as it could "brick" the device. Once finished, the radio will usually restart or beep. Common Troubleshooting
"Check Connection" Error: This is usually a driver issue or the wrong COM port selection. Re-check the Device Manager.
Read/Write Fail: Ensure the radio is turned ON. Also, check that the cable is pushed firmly into the Mini-USB port; some protective cases or dust covers can prevent a flush connection.
Windows 10/11 Issues: If the software won't open, try right-clicking the program and selecting "Run as Administrator" or using Compatibility Mode for Windows 7. Conclusion
