Repeaters are often installed and maintained by radio

clubs, sometimes with the cooperation of local

businesses involved in the communications industry.

Compared to simplex communication, you can usually

transmit over much greater distances by using a

repeater. Repeaters are typically located on a mountain

top or other elevated location. Often they operate at

higher ERP (Effective Radiated Power) than a typical

station. This combination of elevation and high ERP

allows communications over considerable distances.

Activate the Tone function, if necessary.

Select a tone frequency, if necessary.

Press the PTT switch.

REPEATER ACCESS

Most amateur radio voice repeaters use a separate

receive and transmit frequency. You can set a separate

transmit frequency by selecting the offset frequency and

offset direction with respect to the receive frequency. In

addition, some repeaters may require the transceiver to

transmit a tone before the repeater can be used. To

transmit this required tone, activate the Tone function

and select a tone frequency.

The required offset direction, offset frequency, and tone

frequency depend on the repeater you are accessing.

Consult your local repeater reference.

MEMORY CHANNELS

In memory channels, you can store frequencies and

related data that you often use. Then you need not

reprogram those data every time. You can quickly recall

wanted channels by simple operation. A total of 200

memory channels are available for VHF and UHF.

You can also store a name for each memory channel.

For more information, see “NAMING MEMORY

CHANNELS” {page 20}.

SIMPLEX&REPEATER OR ODD-SPLIT MEMORY

CHANNEL?

You can use each memory channel as a simplex&

repeater channel or odd-split channel. Store only one

frequency to use as a simplex&repeater channel or two

separate frequencies to use as an odd-split channel.

Select either application depending on the operations

you have in mind.

Simplex&repeater channel allows:

•Simplex frequency operation

•Repeater operation with a standard offset

(If an offset direction and offset frequency are stored)

Odd-split channel allows:

•Repeater operation with a non-standard offset

Note:

Not only can you store data in memory channels, but you can also

overwrite existing data with new data.

SCAN

Scan is a useful feature for hands-off monitoring of your

favorite frequencies. After becoming comfortable with

how to use all types of Scan, the monitoring flexibility

gained will increase your operating efficiency.

Note:

◆

Remember to adjust the squelch threshold level before using Scan.

◆

You cannot start Scan while Tone Alert is ON.

◆

While using CTCSS, Scan stops for any signal received; however,

the squelch opens only for signals that contain the same CTCSS

tone that is selected on your transceiver.

This transceiver provides the following conventional

scans in addition to “Priority Scan” {page 30} that may

be new to you:

VFO Scan All frequencies tunable on the band

MHz Scan All frequencies within 1 MHz range

SCAN RESUME METHODS

Before using Scans other than Priority Scan, it’s

necessary to decide under what condition you want your

transceiver to continue scanning after detecting and

stopping for a signal. You can choose one of the

following modes. The default is Time-Operated mode.

•Time-Operated mode

Your transceiver stops scanning when detecting a signal,

remains there for approximately 5 seconds, and then

continues to scan even if the signal is still present.

•Carrier-Operated mode

Your transceiver stops scanning when detecting a signal

and remains on the same frequency until the signal drops

out. There is a 2 second delay between signal drop-out and

scan resumption to allow time for any responding stations to

begin transmitting.

•Seek mode

Your transceiver stops scanning when detecting a signal

and remains on the same frequency; the transceiver stays

on this frequency even after the signal drops out and does

not automatically resume scanning.

Note:

Pressing and holding

[MONI]

causes the transceiver to stop

scanning; releasing

[MONI]

causes it to resume scanning.

■Selecting Scan Resume Method

transceiver for more than 2 months. It takes several

charge/ discharge cycles before achieving the full battery

pack capacity.

CAUTION:

◆

EXCEEDING THE SPECIFIED CHARGE PERIOD SHORTENS THE

USEFUL LIFE OF THE NiCd BATTERY PACK.

◆

THE PROVIDED CHARGER IS DESIGNED TO CHARGE ONLY

THE PROVIDED PB-38 OR PB-39 NiCd BATTERY PACK.

CHARGING OTHER MODELS OF BATTERY PACKS WILL

DAMAGE THE CHARGER AND BATTERY PACKS.

Note:

◆

Charging should be done within an ambient temperature between

5

°

C and 40

°

C (41

°

F and 104

°

F). Charging outside this range may

not fully charge the battery.

◆

Always switch OFF the transceiver equipped with the NiCd battery

pack before charging the transceiver. Using the transceiver while

charging its battery pack will interfere with correct charging.

◆

Repeatedly recharging a fully charged battery pack, or almost fully

charged pack, shortens its operating time. To resolve this problem,

use the pack until it is completely discharged. Then recharge the

pack to full capacity.

◆

If the operating time of a battery pack decreases although the battery

pack is fully and correctly charged, the battery pack life is over.

Replace the battery pack.

1Install the NiCd battery pack onto the transceiver

{page 2}.

•Confirm that the transceiver power is OFF.

2Insert the DC plug from the charger into the DC IN

jack on the transceiver.

3Insert the charger AC plug into an AC wall outlet.

•Charging starts and will take approximately 16 hours for

PB-38 or 15 hours for PB-39.

4After 16 hours (PB-38) or 15 hours (PB-39), remove

the charger DC plug from the transceiver DC IN jack.

5Remove the charger AC plug from the AC wall outlet.

TROUBLESHOOTING

The problems described in this table are commonly encountered operational malfunctions. These types of difficulties

are usually caused by improper hook-up, accidental incorrect control settings, or operator error due to incomplete

programming. These problems are usually not caused by circuit failure. Please review this table, and the appropriate

section(s) of this instruction manual, before assuming your transceiver is defective.

Note:

Unmodulated carriers may be received due to internal frequency relationships.

you must use the same transmit and

receive frequency for packet.

3The modulation level from the TNC is

incorrect.

4There is multi-path distortion.

5The squelch is open.

1 Recheck all connections using this

manual, your TNC manual and your

reference.

2If using VFO mode, switch OFF the

transmit offset. If using Memory

Recall, select a simplex memory

channel.

3Adjust the TNC modulation level

according to the TNC manual.

4Reorient the antenna. The

strongest

signal does not always provide the

best operation on packet.
