Navigating the menu system of the Icom IC-706MKIIG is essential for customizing the transceiver’s settings and accessing advanced features. To enter the menu, press the MENU key on the front panel. The display will show the first menu item. Use the main dial or the up/down buttons to scroll through the available menu options. The IC-706MKIIG organizes menus into groups such as M, S, and G, selectable by quick presses of the DISPLAY key.
Once you have selected a menu item, press the ENT (Enter) button to access its settings. Use the main dial or the up/down buttons to adjust the value of the selected setting. Press the ENT button again to save the new setting. To exit the menu, press the MENU button again or wait for the display to time out.
The menu system allows you to adjust various parameters such as display brightness, frequency step size, squelch level, noise reduction, and transmit power. Some menu items may have sub-menus, which can be accessed by pressing the ENT button again. Refer to the IC-706MKIIG manual for a complete list of menu items and their functions. Proper menu navigation ensures optimal transceiver configuration.
Split Frequency Operation
Split frequency operation on the Icom IC-706MKIIG allows you to transmit and receive on different frequencies, a crucial feature for working through repeaters or engaging in DXpeditions. To activate split frequency mode, often denoted as SPL, begin by setting VFO A to your desired transmitting frequency and VFO B to your receiving frequency. You can use the VFO A/B button to switch between the two.
Next, press and hold the SPL key (Split) to engage the split frequency function. The display will indicate that split operation is active. The transceiver will now transmit on the frequency set in VFO A and simultaneously listen on the frequency set in VFO B. Adjust the frequencies as needed using the main tuning dial or direct frequency entry.
Remember that the IC-706MKIIG can be configured to automatically switch between VFOs when the PTT (Push-To-Talk) button is pressed. Ensure your settings are appropriate for your desired mode of operation. To disable split frequency operation, simply press the SPL key again. Utilizing split frequency operation effectively enhances your communication capabilities in various scenarios, ensuring flexibility and control during operation.
Memory Write Function
The memory write function on the Icom IC-706MKIIG allows you to store frequently used frequencies and settings for quick recall. This feature enhances operational efficiency by eliminating the need to manually enter data each time. To store a frequency into memory, first set the desired frequency, mode, and other relevant settings such as tone or offset using the VFO.
Next, press the “MW” (Memory Write) button. The display will prompt you to select a memory channel number. Use the main tuning dial or the keypad to choose an available memory channel. Once the desired channel is selected, press the “MW” button again to confirm and save the settings. The radio will now store the current VFO settings into the selected memory channel.
To recall a memory channel, press the “MR” (Memory Recall) button, and then use the tuning dial or keypad to select the desired channel. Press “MR” again to activate the selected memory channel, loading the stored frequency and settings. This process greatly simplifies operation, especially in situations where quick frequency changes are necessary. Regularly updating your memory channels ensures you have immediate access to your most used frequencies.
Connecting Multiple Units
The Icom IC-706MKIIG can be connected to other compatible devices, enhancing its capabilities and expanding its functionality. One common application is connecting multiple IC-706MKIIG units using the optional CT-17 CI-V level converter. This setup allows for centralized control and monitoring of several transceivers from a single computer or control point.
When connecting multiple IC-706MKIIG units with the CT-17, it’s essential to assign a unique address to each transceiver. This address is configured via the V LEVEL CONVERTER main dial on the CT-17. Each IC-706MKIIG should have a different address within the range of 01H to 7FH to avoid conflicts and ensure proper communication. Connecting the units involves using appropriate CI-V cables to link each IC-706MKIIG to the CT-17.
Once connected and addressed, a computer with compatible software can control various parameters of each transceiver, such as frequency, mode, and output power. This setup is particularly useful in repeater stations or multi-operator environments, providing a streamlined and efficient way to manage multiple radios simultaneously. Proper configuration and addressing are crucial for seamless operation and control.
Troubleshooting Common Issues
The Icom IC-706MKIIG, like any electronic device, may encounter issues over time. Addressing these problems promptly can help maintain optimal performance. One common issue is the transceiver failing to power on. This could be due to a blown fuse, a faulty power cable, or an issue with the power supply itself. Always check the fuse first and ensure the power cable is securely connected.
Another frequent problem is weak or absent transmit output. This can result from incorrect antenna connections, low power settings, or a malfunctioning final amplifier. Verify that the antenna is properly connected and that the power output is set to the desired level. If the issue persists, the final amplifier may require professional attention.
Receiver problems, such as low sensitivity or distorted audio, can also occur; Check the antenna connections and ensure the squelch is properly adjusted. Excessive noise or interference can also degrade receiver performance. Additionally, problems with the display, such as flickering or unreadable text, may indicate a hardware issue requiring service. Consulting the service manual can provide detailed troubleshooting steps for these and other common issues.
Fuse Replacement
The Icom IC-706MKIIG utilizes fuses to protect its internal circuitry from damage due to overcurrent or voltage surges. When the transceiver malfunctions, checking the fuses should be one of the first troubleshooting steps. Before replacing any fuse, always disconnect the DC power cable from the transceiver to avoid electrical shock or further damage.
The IC-706MKIIG typically has two types of fuses installed. The main fuse, usually located near the DC power input, protects the entire transceiver. Additionally, there may be individual fuses for specific circuits or components. Refer to the service manual or schematic diagrams to identify the exact location and rating of each fuse.
When replacing a fuse, always use a fuse of the same type, size, and current rating. Using a fuse with a higher rating can bypass the protection mechanism and potentially damage the transceiver. If a fuse blows repeatedly, it indicates an underlying problem that needs to be addressed by a qualified technician. Replacing the fuse without fixing the root cause will only result in the fuse blowing again. After replacing the fuse, ensure it is securely seated in its holder and then reconnect the DC power cable.
