The Ic-7300 to Operate on 60m transceiver from ICOM that is widely used by amateur radio enthusiasts worldwide. While it is a fantastic piece of equipment, one of its limitations is that it does not support the 60m band. This article will provide step-by-step instructions on how to modify your IC-7300 to operate on the 60m band.

Understanding the 60m Band

Before we dive into the modification process, it is essential to understand the 60m band’s characteristics. The 60m band, also known as the 5MHz band, is a relatively new addition to the amateur radio spectrum. It is a narrow band between 5.250MHz and 5.450MHz, with a maximum power limit of 15W EIRP. Due to its limited bandwidth, it is primarily used for digital modes such as FT8 and WSPR.

Checking the Firmware Version

Before we proceed with the modification, it is crucial to ensure that your IC-7300’s firmware is up to date. To do this, follow these steps:

  1. Press the “Menu” button on the front panel
  2. Navigate to “Set” and press “Enter”
  3. Select “Others” and press “Enter”
  4. Select “Version” and press “Enter”

If your firmware version is not the latest, visit the ICOM website to download and install the latest firmware version.

Obtaining the Modification Kit

To modify your IC-7300 to operate on the 60m band, you will need a modification kit. You can obtain this kit from authorized ICOM dealers or third-party suppliers. The kit includes a new chip and detailed instructions on how to install it.

Disassembling the Transceiver

To install the modification kit, you will need to disassemble the transceiver. This process requires a delicate touch, so be sure to take your time and follow the instructions carefully.

  1. Remove the four screws on the bottom of the transceiver
  2. Carefully lift the bottom cover off the transceiver
  3. Remove the six screws on the top of the transceiver
  4. Carefully lift the top cover off the transceiver

Installing the Modification Kit

Now that the transceiver is disassembled, it is time to install the modification kit. Follow these steps:

  1. Locate the CPU board on the top side of the transceiver
  2. Identify the original chip that controls the band selection
  3. Carefully remove the original chip from the board
  4. Insert the new chip from the modification kit into the same slot
  5. Reassemble the transceiver by reversing the disassembly steps

Testing the Modification

Once you have reassembled the transceiver, it is time to test the modification. Follow these steps:

  1. Press the “Menu” button on the front panel
  2. Navigate to “Set” and press “Enter”
  3. Select “Function” and press “Enter”
  4. Select “USB SEND” and press “Enter”
  5. Set the frequency to 5.405MHz
  6. Ensure that the power output is below 15W EIRP
  7. Transmit a test signal and check that it is received by another station on the 60m band


With this modification, your IC-7300 can now operate on the 60m band. Remember to always adhere to the band’s regulations and power limitations. Happy operating!
