Air to Ground Panel Mount Transceiver
Icom’s A220 panel mount transceiver is a popular fit with experimental and light sport pilots. This ground-to-air transceiver can work on both 8.33 kHz and 25 kHz channel spacing frequencies. It features the brightest OLED (Organic Light Emitting Diode) display on the market, offering many advantages in brightness, vividness, high contrast, wide viewing angle, and response time compared to a conventional display. The A220 also features a built-in two-station intercom, 12 or 24-volt-compatible, automatic squelch, and GPS memory function.

High Visibility OLED Screen

Operating information is clearly shown on the OLED display.

The OLED (Organic Light Emitting Diode) emits light from itself, so a display backlight is not required. It provides higher contrast, wider viewing angle of almost 180 degrees and faster response time than a conventional LCD. The IC-A220's display has a wide active area, allowing operating frequencies to be maximized in the display, while operating status can be shown on both top and bottom of the display.

Base Station & Mobile Configurations

When greater versatility is required, the A220 panel mount has both a base station as well as a mobile option available.

These configurations are perfect for ground crew support, and control tower communications.

Large Switch Buttons

The IC-A220 has large switch buttons on the front panel. The most frequently used FLIP-FLOP (Frequency exchange) switch button is designed large enough to be pushed with ease. All switch buttons and knobs are illuminated with pure-white backlighting, which are the same color as the OLED display.

Auto Squelch Function

The squelch sensitivity is automatically adjusted in accordance with the noise level to eliminate annoying background noise and unwanted signals.

Quick Squelch Adjustment

The auto and manual squelch including squelch level can be quickly adjusted with the Volume knob. The squelch test function temporarily opens the squelch and allows you to monitor signals

GPS Memory Function

When connected to an external GPS receiver* equipped with an airport frequency database, the frequency data such as nearby airports can be transferred and made available in the IC-A220.

* Ask your dealer for available GPS receiver details.

Auto Dimmer

The auto dimmer function sets display and key backlighting brightness. The ICA220’s high sensitivity light sensor covers a wide illumination range.

External Dimmer Control

By connecting to an external dimmer control system on the aircraft, the ICA220’s dimmer function can be linked with the aircraft dimmer level.

Intercom Function

The IC-A220 has a built-in voice activated intercom function allowing the pilot to talk with the copilot via the headset. The IC-A220 has adjustable audio level and squelch control functions.

Remote Control Capability

You can remotely control the FLIP-FLOP (frequency exchange), intercom and recall switches via the rear panel connector

8.33 kHz Channel Spacing

The IC-A220 allows switching between 8.33 kHz and 25 kHz frequency steps in the menu mode.

* Use of 8.33 kHz channel spacing may be prohibited depending on country.

Memory Channels

The IC-A220 has 20 memory channels and 20 history memory channels respectively. Often used memory channels can be instantly recalled. Group memory channels are organized into 10 memory channels by five groups (total 50 channels). Weather channel scanning function searches for weather channel signals.
