Wide
band receiver with dualwatch capability
The IC-91AD
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.
Large
dot-matrix LCD

Using a large full dot-matrix LCD (37.8×20mm; 11/2×25/32
in), the IC-91AD 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.
Simple
bandscope
Spectrum activity is displayed on the screen and audio is
heard while sweeping the range. It is useful for finding new
or interfering signals.
5
Watts (typical) output
Icom’s 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
Keypad
navigation
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.
External
DC power jack
An external DC power jack allows for operation with an external
DC power supply (10–16V DC). When used with the CP-19R
or OPC-254L, simultaneous operation during charging is possible.

Built-in
CTCSS/DTCS encoder and decoder
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.

The IC-91AD is D-STAR ready.
Other
features
Squelch release function to monitor a weak signal.
Water-resistant construction, equivalent to IPX4
Auto power save, power off and power on
26 memory banks with selected bank and bank link scanning
10 channel DTMF memory (16-digit)
10dB (approx) built-in attenuator
Total of 1304 memory channels
Automatic repeater function*
Weather channel with weather alert*
* USA version only
D-STAR DV mode available (Digital Voice + data)
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.
One
touch reply button
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.

Built-in
voice recorder and auto reply function
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
Optional
PC remote control capability
When connected to a PC via an RS-232C cable, most functions
of the IC-91AD* 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

Position
information exchange
When connected to an external GPS receiver (NMEA 0183 format),
your own and other station’s 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.
DX
communication over the D-STAR system
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
