Icom IC-706MKIIG Radio Specification

The Icom IC-706MKIIG is a versatile, compact transceiver designed for amateur radio enthusiasts. It offers multi-band operation, covering HF, VHF, and UHF frequencies, which include 160 meters through 2 meters and 70 centimeters, making it suitable for a wide range of communications. The radio supports all major modes, including SSB, CW, RTTY, AM, and FM, providing flexibility for various operating preferences.

The IC-706MKIIG features a general coverage receiver ranging from 30 kHz to 200 MHz and 400 to 470 MHz, allowing users to listen to a broad spectrum of signals. It delivers a powerful transmit output with 100 watts on HF/6m, 50 watts on 2m, and 20 watts on 70cm, ensuring robust performance across all bands. The inclusion of a built-in DSP unit enhances audio quality by reducing noise and improving signal clarity, essential for effective communication in noisy environments.

The radio is designed with a removable front panel, enabling easy installation in mobile environments. It incorporates a large, backlit LCD for clear visibility of frequency and operational status, even in low-light conditions. Users benefit from a range of features including selectable IF filters, a built-in electronic keyer, and VOX capability. The IC-706MKIIG supports CI-V data communications for seamless computer control and logging.

Advanced features such as automatic repeater shift and CTCSS tone squelch cater to repeater operation, while the automatic antenna tuner interface facilitates quick band changes. The transceiver is powered by 13.8 V DC and is compact in design, making it ideal for both home and mobile installations. Its rugged construction ensures durability, making the IC-706MKIIG a reliable choice for amateur radio operators seeking comprehensive performance in a compact package.

Icom IC-706MKIIG Radio F.A.Q.

How do I perform a factory reset on the Icom IC-706MKIIG?

To perform a factory reset on the Icom IC-706MKIIG, turn off the radio. Then, while holding the [LOCK] and [VFO/MHz] buttons, turn the radio back on. This will reset the radio to its factory default settings.

What is the correct procedure for tuning an antenna with the IC-706MKIIG?

First, connect your antenna tuner to the radio. Set the radio to a low power setting and select the desired operating frequency. Key the transmitter and adjust the tuner for the lowest SWR reading. Repeat the process if necessary for different bands.

How can I improve the audio quality on my IC-706MKIIG for SSB transmissions?

To improve audio quality, ensure that the microphone gain is set correctly, usually around mid-level. Use the speech compressor for clear transmissions and adjust the equalizer settings to enhance audio clarity by reducing low frequencies and boosting midrange frequencies.

Why is my IC-706MKIIG not transmitting on HF bands?

Verify that the radio is not in receive-only mode and that the antenna is properly connected and tuned. Check the SWR to ensure it is within acceptable limits. Also, confirm that the power output settings are correct for HF transmission.

How do I adjust the squelch on the IC-706MKIIG?

To adjust the squelch, turn the [SQL] knob clockwise until the background noise just disappears. This sets the threshold to filter out weak signals and noise, ensuring you only hear transmissions that meet the squelch level.

What is the process for saving frequencies to memory on the IC-706MKIIG?

Select the desired frequency and mode, then press and hold the [MW] (Memory Write) button. Use the tuning dial to select a memory channel and press [MW] again to save the frequency to the chosen memory slot.

How can I reduce RF feedback issues with my IC-706MKIIG?

Ensure that all cables are properly shielded and grounded. Use ferrite chokes on power and microphone cables. Position the antenna away from the operating position and check the SWR to ensure it's within acceptable limits to reduce RF feedback.

What maintenance should be performed regularly on the IC-706MKIIG?

Regularly inspect and clean all connectors and cables. Check for firmware updates from Icom, and ensure the antenna system is in good condition. Periodically check SWR readings and recalibrate your antenna tuner if necessary.

How do I use the noise blanker feature on the IC-706MKIIG?

To use the noise blanker, press the [NB] button to activate it. Adjust the noise blanker level in the menu settings to reduce pulse-type interference. Fine-tune the level for optimal performance without distorting the desired signal.

What are the steps to program repeater frequencies into the IC-706MKIIG?

Enter the repeater's output frequency in VFO mode. Set the offset direction (+/-) and offset value. Activate the CTCSS tone if required by the repeater. Press and hold the [MW] button to store the settings into a memory channel.
