■Your first contact
Now that you have your IC-2820H installed in your car or
shack, you are probably excited to get on the air. We would
like to take you through a few basic operation steps to make
your first “On The Air” an enjoyable experience.
1. Turning ON the transceiver
Before powering up your IC-2820H, you may want to make
sure the audio volume and squelch level controls are set in
9–10 o’clock positions.
Although you have purchased a brand new transceiver, some
settings may be changed from the factory defaults because
of the QC process. Resetting the CPU is necessary to start
from factory default.
➥While pushing both band’s [M/CALL•MW], push and hold
[PWR] for 1 sec. to reset the CPU.
2. Selecting the main band
The IC-2820H displays 2 frequencies on left and right bands
simultaneously. However, transmission, some keys and mi-
crophone’s operation are accepted for the main band only.
➥Push the desired band’s (left or right) [MAIN•BAND] to se-
lect the main band.
•“Q” appears for the main band.

IMPORTANT! (for 50 W transmission):
The IC-2820H is equipped with protection circuit to protect
the power amplifier circuit from high SWR (Standing Wave
Ratio) and temperature. When a high SWR antenna or no
antenna is connected, or when the transceiver temperature
becomes extremely high, the transceiver reduces transmit
output power to 15 W (approx.) automatically.
CAUTION: Transmitting without an antenna will damage
the transceiver.

The transceiver has 3 output power levels to suit your oper-
ating requirements. Low output powers during short-distance
communications may reduce the possibility of interference to
other stations and will reduce current consumption.
➥Push [LOW•PRIO] several times to select the output
power.

during receive only.
■Operating mode selection
Operating modes are determined by the modulation of the
radio signals. The transceiver has total 5 operating modes
(FM, FM-N, AM, AM-N and DV modes). The mode selection is
stored independently for each band and memory channel.
Typically, AM mode is used for the air band (118–136.995 MHz).

■Squelch attenuator
The transceiver has an RF attenuator related to the squelch
level setting. Approx. 10 dB attenuation is obtained at maxi-
mum setting.
The squelch attenuator allows you to set a minimum signal
level needed to open the squelch. The attenuator function can
be deactivated in set mode.
➥Rotate [SQL] clockwise past the 12 o’clock position to ac-
tivate the squelch attenuator.
•Attenuation level can be adjusted up to 10 dB (approx.) between
12 o’clock and fully clockwise position.
NOTE: The squelch attenuator functions even when the
monitor function is in use. Thus set the [SQL] control
within 10 to 12 o’clock position is recommended when
using the monitor function.

DDDiversity operation
The diversity receiving compares the receiving signal strength
from two different antennas, ANT1 and ANT2, and automati-
cally selects the strongest signal. This feature is useful when
you are listening in a moving vehicle or the transmitting sta-
tion itself is moving. Diversity receiving is available in
127 MHz, 136 MHz, 146 MHz, 375 MHz, 440 MHz and
500 MHz bands only.

REPEATER OPERATION
4
29
■General
Repeaters allow you to extend the operational range of your
radio because a repeater has much higher output power than
the typical transceiver.
Normally, a repeater has indipendent frequencies for each re-
ceiver and transmitter.
A subaudible tone may also be required to access a repeater
Reference amateur radio hand books and local ham maga-
zines for details of local repeaters such as repeater input/out-
put frequencies and locations.
•Repeater operation flow chart
•The IC-2820H USA version has the auto repeater function. Thus the
steps 3 and 4 may not be necessary, depending on the setting.
•Repeater settings can be stored into a memory channel.
Step 3:
Set the duplex (shifting) direction (– duplex or +duplex).
- Set the offset frequency (shifting value), if required.
Step 4:
Set the subaudible tone (repeater tone) encoder function ON.
- Set the subaudible tone frequency, if required.
Step 1:
Set the desired band to operate the repeater.
Step 2:
Set the desired receive frequency (repeater output frequency).
Repeater example;
Receives the 444.540 MHz signal
and the detected audio signals are
transmitted on 449.540 MHz simul-
taneously.
Station A:
Tx: 444.540 MHz

DSubaudible (repeater) tone
Some repeaters require subaudible tones to be accessed.
Subaudible tones are superimposed over your normal signal
and must be set in advance. (P ??)
DTone, DTCS, Digital code and Digital call
sign squelches
The tone squelch (CTCSS), DTCS squelch, digital code
squelch or digital call sign squelch opens only when receiving
a signal containing a matching subaudible tone, DTCS code,
Digital code or Digital call sign squelch respectively. You can
silently wait for calls from group members using the same
tone or code. Separate tone frequencies can be set for re-
peater and tone squelch/pocket beep operation.
DPocket beep
These functions use subaudible tones or DTCS codes for
calling and can be used as a “common pager” to inform you
that someone has called while you were away from the trans-
ceiver.

■Pager function
This function uses DTMF codes for paging and can be used
as a “message pager” to confirm you of a caller’s identification
even when you leave the transceiver temporarily unattended.
■
Code programming
DDBefore programming
The pager and code squelch functions require ID codes and a
group code. These codes are 3-digit DTMF codes and must
be written into the code channels before operation.
qDecide the ID code of each transceiver and a group code
for your group.
wDecide whether you want to return to normal operation or
code squelch operation after a connection is made.
eProgram the ID code, group code and transmit codes
(other station’s codes) as below.

For your information
The IC-91A/91AD has call sign edit record function.
When editing a call sign stored in a call sign memory, regular
memory or call channel, the default setting is to store the
edited call sign into a blank channel automatically. (“FULL” is
displayed when all call sign memory is programmed.)
The edited call sign can be over-written when the setting of
the EDIT RECORD is set to OFF or SELECT. (p. 95)
However, you must manually over-write a programmed call
sign in regular memory and call channels. (Temporary opera-
tion without over-writing is possible.)

13 DV MODE OPERATION (Optional UT-123 is required)
■About D-STAR system
In the D-STAR system, repeater linking via a 10 GHz band
backbone and internet network (gateway connection) capa-
bilities are available. This system provides you to with much
wider coverage range during digital voice mode operation.
• D-STAR system outline
For current repeater operation, stations that are communicat-
ing must both be in the same repeater’s operating area.
However, in the D-STAR system as in the illustration at left,
the repeaters can be linked via the system repeaters (with a
10 GHz signal). Thus stations A and B can communicate even
though they are in different repeater operating areas.
Also, the D-STAR system repeaters are connectable through
the internet— gateway connection capability.
For example, when station B uses the gateway connection
station B can communicate with the station C!
By using the gateway connection, long distance communica-
tion like DX operation may be possible with 144 or 440 MHz
digital voice!
In the D-STAR system, an independent repeater’s operating
area is called an Area and a group that of linked repeaters via
a 10 GHz backbone is called a Zone.

13 DV MODE OPERATION (Optional UT-123 is required)
■Received call sign
When a call is received in DV mode, the calling station and
the repeater call signs being used can be stored into the re-
ceived call record. The stored call signs are viewable in the
following manner.
Up to 20 calls can be recorded.
DDDesired call record indication
qEnter RX call sign set mode.
•RX CALL SIGN screen is displayed.
wRotate [DIAL]†to select the desired record channel.
eTo confirm the received call, push [ï](5) several times to
select the desired call sign from CALLER, CALLED,
RXRPT1 and RXRPT2.
CALLER : The station call sign that made a call.
CALLED : The station call sign called by the caller.
RXRPT1 : The repeater call sign used by the caller station.
RXRPT2 : The repeater call sign linked from RXRPT1.
rPush [MENU/LOCK] to return to frequency indication.
NOTE: When a call is received in DV mode when the
power save function is activated, the call sign may not be
received correctly.
This is normal, not a malfunction, because of header of the
call sign cannot be detected during power save.
Turn the power save function OFF (p. 115) if you want to
receive a call sign correctly even in stand-by condition.
✔
For your information
When receiving a call, the received station call sign is auto-
matically displayed and scrolled in sequence at the bottom
line of the function display.
This can be turned OFF in display set mode. (p.100)

•Error beeps sound when a call sign is received incorrectly, and
no call sign is set in this case.
wPush [PTT] to transmit; release to receive.
✔
For your information
When a call specifying your call sign is received, the call signs
of the calling station and the repeater it is using can be used
for operation automatically.
•When “RX call sign auto write” (p. 93) is set to “AUTO,” the
station call sign in “CALLER” is set to “UR” automatically.
•When “Repeater call sign auto write” (p. 93) is set to “AUTO,”
the stored station call sign in “RXRPT1” is stored as “R2”
and “RXRPT2” is stored as “R1” automatically.
Important!
Setting call signs with the “One-touch reply using the call
record” operation as at left are for temporary operation only.
Therefore, the set call signs will be overwritten when an-
other call record is used to set call signs.
•Never saved into a call sign memory.
If you want to save the set call signs, see “Copying the call
record contents into call sign memory” (p. 50) for details.

DCloning error
☞NOTE: DO NOT push any key on the sub-transceiver dur-
ing cloning. This will cause a cloning error.
When the display as below appears, a cloning error has oc-
curred.
In such a case, both transceivers automatically return to the
clone standby condition and cloning must be repeated.
■Packet operation
DData speed
For packet operation, the transceiver can be set to one of two
data speeds: 1200 bps (default) or 9600 bps.
qWhile pushing [FF•]turn power ON to enter initial set
mode.
wPush
[FF•]
or [LOW•PRIO] to select the ‘bPS’item.
eRotate the left band [DIAL] to select the desired data
speed.
rPush [PWR] to exit initial set mode.
For 1200 bps operation—
•Disconnect the microphone plug from the microphone
connector during data transmission, otherwise the data
signal and voice signal are simultaneously transmitted.
For 9600 bps operation—
•When the transceiver is set for 9600 bps data transmis-
sion in set mode, the microphone signal is automatically
cut. Therefore, it is not necessary to disconnect the mi-
crophone plug from the connector in this case.
•
When pushing [PTT] during data transmission, data trans-
mission is interrupted and voice signals have priority.

rAdjust the TNC frequency deviation if necessary.
•When using a deviation meter:
Adjust the output of the TNC so that frequency deviation
is in the range ± 3 to ±4 kHz.
•When NOT using a deviation meter:
A receiver or transceiver is needed to monitor the trans-
mission—compare the received audio output level when
receiving a TNC modulated signal with high level voice
signals using the microphone. Then adjust the TNC mod-
ulated signal to a lower level than the voice modulated
signal.

•When using the PTT P terminal for packet operation, no
voice signals are transmitted from the microphone.
•When pushing [PTT] during data transmission, data
transmission is interrupted and the voice signal takes pri-
ority.
•Read the instructions supplied with your TNC carefully
before attempting packet operation with the transceiver.
•Pin rDATA OUT is for 9600 bps operation only. This pin
cannot be used for 1200 bps operation.
DAdjusting the transmit signal output from
the TNC
When setting data transmission speed to 9600 bps, the data
signal coming from the TNC is applied exclusively to the in-
ternal limiter circuitry to automatically maintain band width.
NEVER apply data levels from the TNC of over 0.6 V p-p, oth-
erwise the transceiver will not be able to maintain the band
width and may possibly interfere with other stations.
1. When using a level meter or synchroscope, adjust the
TX audio output level (DATA IN level) from the TNC as
follows.
0.4 V p-p (0.2 V rms) : recommended level
0.2 V p-p–0.5 V p-p (0.1–0.25 V rms) : acceptable level
2. When NOT using a measuring device.
qConnect the transceiver to a TNC.
wEnter a test mode (“CAL”, etc.) on the TNC, then trans-
mit some test data.
eWhen the transceiver fails to transmit the test data or
transmits sporadically (TX indicator doesn’t appear or
flashes):
- Decrease the TNC output level until the transmit indi-
cator lights continuously.
When transmission is not successful even though the
TX indicator lights continuously:
- Increase the TNC output level.
