When the optional UT-123 Digital/GPS unit is installed
the IC-2820H advanced mobile is capable of both D-STAR
Digital Voice and GPS operation. The IC-2820H GPS features
include; position information exchange, plotting your
position onto mapping software on a PC. Advanced features;
D-STAR Digital Voice facilities and GPS functionality take
the IC-2820H into a new realm of Amateur radio
communications.
VHF/VHF, UHF/UHF simultaneous receive capability
The IC-2820H is a true dual band transceiver. VHF/VHF,
UHF/UHF as well as VHF/UHF simultaneous receive is
possible. A simple push of a button allows you to change
between the main (transmit) band and sub-band.
Diversity receive capability
Diversity receive* mode is useful for mobile operation
where the received signal strength changes continuously.
It compares the signal strength and chooses the antenna
with the better signal to maintain good sound and receive
quality.
* Two antennas are required. 127, 136, 146, 375,
440, 500MHz band in FM/FM-N/DV mode only. Diversity
reception is not available while using the dualwatch.
Large full dot-matrix display
The IC-2820H has a large full dot-matrix display (93x28
mm). The dot-matrix display provides graphical
user-friendly operation. For example, when you push the
“Function” button, you can call up the function menu of
the assigned functions above each button. The background
colour of the display is selectable from green, orange to
amber colour in 21 steps.
Independent tuning knob for each band
The IC-2820H provides easy to use, user-friendly
operation. The independent tuning knob provides simple and
quick tuning. Volume, squelch and other function switches
are symmetrically laid out for each band. In addition,
there are two speaker jacks for each band on the main
unit.
50W output power in both VHF and UHF bands
A newly designed MOS-FET power amplifier provides a
powerful 50W both in the 144MHz and the 430 MHz bands,
making this compact rig capable of long distance
communication! Output power is selectable in 3 steps.
Optional UT-123 (includes GPS antenna)
The optional UT-123 provides Digital Voice mode operation
plus GPS receiver capability. When installed, the IC-2820H
is compatible with the JARL D-STAR format and your
position data can be sent simultaneously with digital
voice transmission.
Other features of the UT-123 include:
Position information exchange
When connecting the GPS antenna (supplied with the UT-123)
to the GPS jack, your own position information can be sent
to other stations. The IC-2820H sends the position data
either by holding the PTT switch, or at a preset interval
(5 seconds–30 minutes), depending on the setting.
Plotting position information on a mapping software
When connected to a PC* via the optional OPC-1529R
(RS-232C cable), position information can be plotted on
mapping software* on a PC.
* Serial port and position mapping software (NMEA
0183 format) are required.
GPS alarm
The GPS alarm sounds when your own position is close to
the specified point or area.
One touch reply function
The IC-2820H has a one-touch reply function. It uses the
received callsign (including repeater callsign) and allows
you to call back to the calling station without hassle. In
addition, up to 20 received callsigns are stored as the
received call record.
Callsign function
Stores My (own), Your (other stations) and repeater 1/2
callsigns in the memory. “Your” and “repeater 1/2”
callsign memory stores 60 callsigns with 8-character
channel comment for each. Own callsign and up to a
20-character message can be sent at the beginning of each
call. The received callsign and message are decoded on the
display.
Built-in digital voice memory recorder and auto reply
The UT-123 has a built-in voice memory recorder*. It
records an incoming call for up to 30 seconds (approx.),
or can be partitioned into 3 tracks (10 seconds each). The
10-second transmit memory allows you to record your
callsign, CQ message, etc, and automatically answers when
you receive a message.
* Available in DV mode only.
950bps data communication in DV mode
When connected to a PC* via the optional OPC-1529R RS-232C
cable, 950bps data communication is available.
* Serial port and serial communication software are
required.
522 memory channels
The IC-2820H has a total of 522 memory channels, 500
regular channels, 2 call channels and 20 scan edges. Each
memory channel stores tone frequency, skip information
etc. Icom's Dynamic Memory Scan (DMS) system divides these
memories into 26 groups, A to Z which provides easy
channel selection. Bank scanning is also possible.
Built-in wide band receiver
In addition to the VHF/VHF, UHF/UHF dual band
capabilities, the IC-2820H has a wideband receiver which
covers 118–549.995 and 810–999.990MHz*. This means you can
listen to various communications in your vehicle or shack.
The IC-2820H has high speed scan capability of
45-channel/sec. (in program scanning mode). This allows
you to scan quickly when searching a wide frequency range.
*
Excluding Cellular range. AM, FM, N-FM mode only.
Separate controller from main unit
For easy installation, the controller is separate from the
main unit. The controller has magnets on the rear panel,
so you can attach it to the main unit or other metal
objects.
HM-133, remote control microphone
The IC-2820H come as standard with a HM-133 remote control
microphone. The 10-key pad allows you to enter the
frequency directly. The F1/F2 buttons memorise the
transceiver’s full settings. All operating frequencies,
tone settings as well as the display colour, fan speed,
and set mode settings are memorised.
104x2 DCS/50 CTCSS tone squelch operation is standard
CTCSS and DCS tone signalling systems provide quiet
stand-by and useful functions such as pocket beep and tone
scan. The pocket beep alerts the operators with a beep
sound, when the transceiver receives a signal containing a
pre-set tone. Tone scan detects the tone frequency used
for opening a repeater or for tone squelch operation.
