10 SUB-RECEIVER

ATTENUATOR

The attenuator reduces the level of received signals.

It is useful when there is strong interference from an

adjacent frequency. Since the main transceiver and

sub-receiver share the same antenna for the 144

MHz and 430/ 440 MHz bands, activating the

attenuator function for the sub-receiver also causes

the function to switch ON for the same band of the

main transceiver.

PRE-AMPLIFIER

The pre-amplifier amplifies the level of received

signals. It is useful when the receiving signal is weak.

If there is no strong interference from adjacent

frequencies, switch the pre-amplifier ON to raise the

receiving signal level. Since the main transceiver and

sub-receiver share the same antenna for the 144 MHz

and 430/ 440 MHz bands, activating the pre-amplifier

function for the sub-receiver also causes the function

to switch ON for the same band of the main

transceiver.

DUAL WATCH

If different frequency bands are set on the main

transceiver and sub-receiver, you can still monitor the

other band activities while transmitting on the TX

band. It is useful that you can still monitor the local

repeater frequency (VHF or UHF band) while you are

working on a DX station on the HF band of the main

transceiver.

If you have the same frequency band (VHF or UHF

band) for the main transceiver and sub-receiver, you

can monitor both frequencies independently at the

same time. However, both receivers will temporarily

mute when you transmit because the transceiver

shares the same 144 MHz and 430/ 440 MHz band

antenna between the main transceiver and sub-

receiver.

SCAN

All types of scanning are also available for the sub-

receiver. However, the operating frequency range is

limited to the sub-receiver’s frequency coverage.

Refer to “SCAN” {page 66} for details on how to

operate the scan function.

NOISE REDUCTION

Since the sub-receiver can receive only in FM or AM

mode, DSP noise reduction 1 (Line Enhanced) is

available to reduce the noise from the receiving

signals. Refer to “NOISE REDUCTION” {page 56} for

details on how to control and adjust the function.

TRANSMITTING

First, confirm that the “ ” icon is on the SUB band

display. Press [SEND] or press and hold Mic [PTT],

then speak into the microphone in your normal tone

of voice. When you finish speaking, press [SEND]

again or release Mic [PTT].

SELECTING A TRANSMIT POWER

You can also adjust the output power for FM mode on

the 144 MHz and 430/ 440 MHz bands when you are

operating the sub-receiver.

1 Press [PWR].

• The current transmit power appears.

2 Turn the MULTI/ CH control counterclockwise to

reduce the power or clockwise to increase the

power.

Note:

◆

The selectable range varies depending on the band and mode

{page 79}.

◆

Output power configuration is also reflected in the main

transceiver.

MICROPHONE GAIN

Access Menu No. 41 and select “LOW”, “MID”, or

“HIGH” for the microphone gain.

Note: When using the optional MC-90 microphone in FM mode,

select “HIGH” microphone gain. Microphone sensitivity is low in FM

mode; this may cause insufficient modulation. For other

microphones, select “MID” or “LOW”.

FM REPEATER OPERATION

You can also configure an independent repeater

offset frequency for the sub-receiver, if necessary.

Refer to “FM REPEATER OPERATION” {page 32} for

details.

REVERSE FUNCTION

Press [TF-SET] to switch the sub-receiver Reverse

function ON (or OFF). “R” appears while the Reverse

function is active on the sub-receiver. Refer to

“REVERSE FUNCTION” {page 34} for details.
