frequency and operating mode for operation.

VFO is an abbreviation of Variable Frequency Oscillator, and traditionally refers to an oscillator. The IC-706MKIIG’s VFO can store a frequency and an operating mode.

You can call up a desired frequency to a VFO with the memo pad-read switch (p. 42) or with the memory transfer switch (p. 42). You can also change the fre-

quency with the main dial and select an operating mode with the [MODE] switch or call up previously accessed frequency and modes with the band stack- ing register (p. 19).

The IC-706MKIIG has two VFOs, specially suited for split frequency operation. The VFOs are called VFO A and VFO B. You can use the desired VFO to call up a

•The differences between VFO and memory mode

VFO MODE

Each VFO shows a frequency and operating mode. If the frequency or operating mode is changed, the VFO automatically memorizes the new frequency or operating mode.

When the VFO is selected from another VFO or memory mode, the last-used frequency and operat- ing mode for that VFO appear.

MEMORY MODE (pgs. 39–42)

Each memory channel shows a frequency and oper- ating mode like a VFO. Even if the frequency or mode is changed, the memory channel does not memorize the new frequency or memory mode.

When a memory channel is selected from another memory channel or VFO mode, the memorized fre- quency and operating mode appear.

I706MKTMG, IC-706MKIIG specifications

The Icom IC-706MKIIG and the Icom IC-706MKTMG are two prominent transceiver models known for their compact design and versatile capabilities. These radios cater to amateur radio enthusiasts, providing a wide range of features suitable for both HF and VHF/UHF operations.

The IC-706MKIIG is a well-regarded dual-band transceiver that operates on HF frequencies from 160 meters to 10 meters and VHF/UHF from 6 meters to 70 centimeters. One of its main features is its compact footprint, making it an excellent choice for mobile operations as well as fixed installation. The transceiver provides up to 100 watts of output power on HF and 50 watts for VHF/UHF, ensuring robust performance for various amateur applications.

On the other hand, the IC-706MKTMG brings the same foundational performance but includes enhanced features aimed at improving user experience. It boasts a high-resolution LCD display with clear visibility under varying light conditions. This model offers advanced digital signal processing (DSP) technology, enhancing audio clarity and reducing noise interference. The built-in auto notch filter and noise blanker efficiently eliminate unwanted signals, allowing users to focus on their desired contacts without distraction.

Both models support multiple modes of operation, including SSB, CW, AM, and FM, which provides versatility in how users can communicate. They feature an easy-to-navigate menu system, allowing users to access settings quickly. With built-in memories and a large number of program settings, operators can customize their experience and quickly switch between configurations.

One standout feature of the IC-706 series is its built-in antenna tuner, which helps match the transceiver to various antenna types, optimizing performance and simplifying setup. The radios also include support for external control via CAT commands, accommodating advanced integration into larger station setups.

In terms of user connectivity, both transceivers come equipped with USB ports and support sound card capabilities, enabling digital modes such as PSK31 and RTTY easily. This integration enhances versatility, catering to modern digital communications alongside traditional voice modes.

Robust, reliable, and feature-rich, the Icom IC-706MKIIG and IC-706MKTMG models stand out as exemplary choices for amateur operators looking for a compact yet comprehensive transceiver solution. Their combination of technologies and characteristics continues to make them popular in the ham radio community.
