IC-91A / IC-91ADVHF / UHF Dual Band Transceiver

The D-STAR repeaters for 144, 440MHz are now available. It allows cross band (144/440/1200MHz) operation and long distance communication over the D-STAR system

When connected to an external GPS receiver (NMEA 0183 format), your own and other stations position information can be sent and received*. The IC-91AD sends the position data either by holding the PTT switch, or at a preset interval (5 sec.30 min.), depending on the setting.
* GPS data receive only when no external GPS receiver is attached.

When connected to a PC via an RS-232C cable, most functions of the IC-91AD/A* can be controlled from the PC with the optional RS-91 software. In DV mode operation, you can send and receive short messages of 20 characters (Max.) on the PC.
* Also available in analog mode

The built-in voice recorder* records an incoming call for up to 30-seconds (approx.), (or 15 sec. ? 2 tracks, 10 sec. ? 3 tracks). The 10 sec. transmit memory allows you to record your callsign, CQ and automatically answers when you receive a message.
* Available in DV mode only

The newly adopted one-touch reply [CALL RX->CS] button memorizes the received callsign(s) at the touch of the button. This function allows you to respond to the calling station without hassle. In addition, up to 20 received callsigns are stored in a received call history.

The IC-91AD* provides DV mode operation with an AMBE codec. 950 bps data can be sent simultaneously with the digital voice transmission. When you receive an FM mode (or other mode) signal while operating in DV mode, the automatic DV detection function changes the operating mode to the one detected.
* Optional UT-121 is required for use with IC-91A.

CTCSS and DTCS tones are used for accessing a repeater or for tone squelch operation. The pocket beep alerts you with a beep sound when the transceiver receives a preset tone.

An external DC power jack allows for operation with an external DC power supply (1016V DC). When used with the CP-19R or OPC-254L, simultaneous operation during charging is possible.

The 4 cursor direction buttons on the keypad gives you quick and intuitive access to many settings. The twin volume/channel knob provides convenient channel/volume setting.

Icoms original wideband PA circuit and supplied lithium-ion battery pack provides 5W (typ.) output. The supplied BP-217 provides up to 5/4.5 hours* of operating time and greatly reduces both the size and weight needed to obtain full output power.
* VHF/UHF single mode, Tx high: Rx: Stand-by duty ratio= 1: 1: 8

Spectrum activity is displayed on the screen and audio is heard while sweeping the range. It is useful for finding new or interfering signals.

Using a large full dot-matrix LCD (37.8?20mm; 1¹/₂?2⁵/₃₂ in), the IC-91AD/A clearly shows two-line frequency settings, alphanumeric channel name, bandscope, etc. You can choose large or small font size in the setting mode. In addition, automatic LCD and keypad backlighting provides bright illumination for night time operation.

The IC-91AD/A has dualwatch receiver capability, allowing you to receive* two bands simultaneously (including same band). By pushing and holding the [Main/Dual] button, you can easily turn dualwatch on and off, while a press of the button allows you to toggle the active VFO channels.
*See specifications for receive range coverage.
