4 RECEIVE AND TRANSMIT

Split frequency operation

Split frequency operation allows you to transmit and receive on two different frequencies. Split frequency operation uses 2 frequencies, one in VFO A and the other in VFO B.

Following is an example of setting 7.057 MHz, CW mode in VFO A (for receive) and 7.025 MHz, CW mode in VFO B (for transmit).

CW

SPL

VFO B

The transmit frequency can be monitored while pushing [(F-3)XFC].

Split operation is now set for receive on 7.057 MHz/CW and transmit on 7.025 MHz/CW.

Select VFO A and set the frequency to 7.057 MHz/CW.

[(F-2)A/B] is available when M1 appears.

[(F-3)V/M] is available when M2 appears.

CW

VFO A

Push or push and hold [(F-1)SPL] in the M1 dis- play.

Push [SPL]: activates split only.

Push and hold [SPL]: activates the quick split below.

To change the receive frequency, rotate the main dial; to change the transmit frequency, rotate the main dial while pushing [(F-3)XFC].

To exchange the transmit and receive frequencies, push [(F-2)A/B] in M1.

CONVENIENT

The G3 display conveniently shows the transmit fre- quency during split frequency operation and [(F-3)Ñ] allows you to change the transmit frequency.

Split lock function

The split lock function is convenient for changing only the transmit frequency. Otherwise, accidentally releasing the [(F-3)XFC] switch while rotating the main dial changes the receive frequency. The split lock’s effectiveness can be selected in initial set mode (item 12) for both receive and transmit fre- quencies; or only the receive frequency. (p. 52)

DQuick split function

In M1, when you push [(F-1)SPL] for 2 sec., split fre- quency operation is turned ON and VFO B is auto- matically changed according to the plus/minus pre- programmed shift frequency set in initial set mode (or equalized when 0 kHz is programmed as the split shift frequency). This shortens the time needed to start split frequency operation—great for DX’ing.

The quick split function is ON by default. If desired, it can be turned OFF in initial set mode (p. 51). In this case, pushing [(F-1)SPL] for 2 sec. has the same effect as pushing [(F-1)SPL] momentarily as in nor- mal split operation.

PROGRAMMING SPLIT SHIFT FREQUENCY

Push [POWER] to turn power OFF.

While pushing [LOCK], push [POWER] to turn power ON and enter initial set mode.

Select “SPL OFFSET” using [MENU], [M-CH] or the [Y]/[Z] keys, then rotate the main dial to select the desired split offset.

The split offset can be selected from –4000 kHz to +4000 kHz.

16 SPL OFFSET

Note: This setting is not valid for FM operation. This is because FM operation uses the duplex setting for repeater operation (next page).

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.
