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.
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,
alphanumericchannel name, bandscope, etc. You can hoose large or small font
size in the setting mode. In addition, automatic LCD and keypadbacklighting
provides bright illumination for night time operation.
Spectrum activity is displayed on the screen and audio is heard while sweeping the range. It is useful for finding new or interfering signals.
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
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 jackAn 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.
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.
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.
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 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
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
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.
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
