Smooth sailing ahead with this all mode marine transceiver

150 W output power
Icom introduces the IC-M700, a full-featured 150 W HF transceiver that will keep you in touch at all times with the shore and other vessels.

Easy operation
Channel selection can be quickly and easily performed with the CHANNEL GROUP and CHANNEL SWITCHES.

Full coverage
The IC-M700 features full transmit and receive coverage of all marine bands through 2.000~22.9999 MHz. The IC-M700 covers all ship-to-shore frequencies using simplex or semi-duplex mode.

General coverage receiver
The IC-M700 provides general coverage receiving through 1.6000~23.9999 MHz. You can receive news broadcasts such as UPI and AP, weather reports, WWV time signals, FAX weather charts, foreign broadcasts, etc.

PLL circuit
A quartz-locked synthesized tuning system provides superb stability without you ever having to purchase expensive crystals or PROMs.

48 memory channels
48 memory channels are easily programmed with the keyboard on the front panel. Independent transmit and receive frequency programming provides complete flexibility.

All mode capability
High seas transmission is possible in J3E, R3E and H3E modes.

Automatic antenna tuner
The optional AT-120 HF AUTOMATIC ANTENNA TUNER matches a wide range of antenna impedances. For example, the tuner will match a 7-meter (23 feet) long-wire antenna through 2~23 MHz.

2182 kHz safety signal
When an optional UT-20 ALARM UNIT is installed, 2182 kHz international safety signals can be transmitted if your ship is in distress.

The optional IC-HS2 HANDSET KIT is perfect for communicating during difficult offshore conditions. The IC-HS2 is also great for listening privacy on board.
