Understanding the Alinco DR-735

The Alinco DR-735 is a popular dual-band transceiver known for its versatility and user-friendly design. It's a great choice for both beginners and experienced hams, offering a wide range of features in a compact package. Some of its key features include:

• Dual-band operation (144/430 MHz)
• 50W output power
• 1,000 memory channels
• Built-in CTCSS/DCS encoder/decoder
• Wide and narrow FM modes
• Various scanning functions
• PC programming capability

One of the most significant advantages of the DR-735 is its ability to be programmed via a computer. This makes it much easier to manage the large number of memory channels and customize the radio to your specific needs. Instead of manually entering frequencies and settings, you can use software to quickly and efficiently configure your radio.

Why Use Programming Software?

Programming your Alinco DR-735 manually through the radio's menu can be a tedious and time-consuming process. Programming software offers several advantages:

• Speed and Efficiency: Programming software allows you to enter and edit frequencies, tones, and other settings much faster than using the radio's keypad.
• Organization: It's easier to organize and manage your memory channels using a visual interface. You can create groups, sort channels, and easily find what you're looking for.
• Backup and Restore: You can save your radio's configuration to a file and restore it later if needed. This is especially useful if you accidentally reset your radio or want to transfer your settings to another DR-735.
• Cloning: Some software allows you to clone the settings from one radio to another, making it easy to configure multiple radios with the same settings.
• Reduced Errors: By using software, you minimize the risk of making errors when entering data manually.

Connecting Your Radio to the Computer

To program your Alinco DR-735 with software, you'll need to connect it to your computer using a programming cable. The cable typically connects to the radio's data port (usually located on the back or side of the radio) and to a USB port on your computer.

Types of Programming Cables:

• USB Programming Cable: This is the most common type of cable. It connects to the radio's data port and to a USB port on your computer. Make sure you get the correct cable for the Alinco DR-735.
• Serial Programming Cable: Some older radios may use a serial programming cable, which connects to the radio's data port and to a serial port on your computer. However, serial ports are becoming less common on modern computers, so you may need a USB-to-serial adapter.

Installing the Cable Driver:

Before you can use the programming cable, you may need to install the driver software. The driver allows your computer to communicate with the radio. The driver usually comes with the programming cable or can be downloaded from the cable manufacturer's website.

1. Insert the programming cable into a USB port on your computer.
2. If prompted, allow Windows to search automatically for drivers. If this doesn't work, you'll need to install the driver manually.
3. Locate the driver software (either on a CD that came with the cable or downloaded from the manufacturer's website).
4. Run the driver installer and follow the on-screen instructions.

Finding the Correct COM Port:

After installing the driver, you need to determine which COM port your computer has assigned to the programming cable. This information is needed by the programming software to communicate with the radio.

In Windows:

1. Open the Device Manager (search for "Device Manager" in the Start menu).
2. Expand the "Ports (COM & LPT)" section.
3. Look for the USB serial port associated with your programming cable (it may be labeled with the cable manufacturer's name).
4. Note the COM port number (e.g., COM3, COM4, etc.).

Programming Your Alinco DR-735: A Step-by-Step Guide

Here's a general step-by-step guide on how to program your Alinco DR-735 using programming software. The exact steps may vary depending on the software you're using, but the basic principles are the same.

1. Install the Programming Software: Download and install your chosen programming software (Alinco's software, CHIRP, RT Systems, etc.).
2. Install the Cable Driver: Install the driver for your programming cable.
3. Connect the Radio: Connect the programming cable to your radio and your computer.
4. Determine the COM Port: Find the COM port number assigned to your programming cable in the Device Manager.
5. Launch the Programming Software: Open the programming software.
6. Configure the Software: In the software settings, select the correct COM port for your programming cable.
7. Read from Radio: Use the software to read the current configuration from your radio. This will download the existing memory channels and settings into the software.
8. Edit the Configuration: Modify the memory channels, frequencies, tones, and other settings as needed. You can add new channels, delete existing ones, and change the parameters of each channel.
9. Write to Radio: Once you've made your changes, use the software to write the new configuration back to your radio. This will update the radio's memory with your new settings.
10. Verify the Configuration: After writing to the radio, it's a good idea to verify that the changes were successfully applied. You can do this by reading the configuration from the radio again and comparing it to the configuration in the software. You can also manually check some of the channels on your radio to ensure they are programmed correctly.

Tips and Tricks for Successful Programming

• Double-Check the COM Port: Make sure you've selected the correct COM port in the programming software. If the COM port is incorrect, the software won't be able to communicate with the radio.
• Use a Stable USB Port: Avoid using USB hubs or extension cables, as they can sometimes cause communication problems. Plug the programming cable directly into a USB port on your computer.
• Turn Off the Radio: Some radios require you to turn them off before connecting the programming cable. Check the radio's manual for specific instructions.
• Backup Your Configuration: Before making any changes, always back up your radio's current configuration to a file. This way, you can easily restore your settings if something goes wrong.
• Read Before Writing: Always read the configuration from the radio before making any changes. This will ensure that you're starting with the correct settings and avoid overwriting anything important.
• Test Your Channels: After programming your radio, test each channel to make sure it's working correctly. Verify that the frequency, tone, and other settings are correct.
• Consult the Manual: If you're having trouble, consult the radio's manual or the programming software's documentation. These resources often contain helpful troubleshooting tips.

Troubleshooting Common Issues

• Cannot Connect to Radio:
  • Check the COM port settings.
  • Ensure the programming cable is securely connected.
  • Verify the cable driver is installed correctly.
  • Try a different USB port.
• Software Not Recognizing Radio:
  • Make sure you've selected the correct radio model in the software.
  • Try restarting the software and the radio.
  • Check for software updates.
• Data Transfer Errors:
  • Use a stable USB port.
  • Avoid using USB hubs or extension cables.
  • Close other programs that may be using the COM port.
