7 ENHANCED COMMUNICATIONS

FM REPEATER OPERATION

Most Amateur radio voice repeaters use a separate

reception and transmission frequency. The

transmission frequency may be higher or lower than

the reception frequency. In addition, some repeaters

may require the transceiver to transmit a subtone

before the repeater can be used.

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.

HF/ 6 m band repeaters operate usually in the

29 MHz FM sub-band and 51-54 MHz band. This

special service combines the advantages of FM

operation, good fidelity with noise and interference

immunity, with the excitement of HF DX (long

distance) communications. Even on a quiet day,

10 m FM provides reliable around-town

communications with the potential for sudden DX

from across the country or around the world.

Note:

◆

When programming 2 separate frequencies using 2 VFOs, be

sure to select FM mode on both VFOs.

◆

When operating through a repeater, over deviation caused by

speaking too loudly into the microphone can cause your signal to

“talk-off” (break up) through the repeater.

1 Press [A/B / M/V] to select VFO A or VFO B.

•“tA” or “tB” appears to show which VFO is

selected.

2 Turn the Tuning control or MULTI control to select

the reception frequency.

3 Press [MODE] to select FM mode {page 19}.

4 Press [A=B/ SPLIT] to duplicate the frequencies

and other data to the other VFO.

5 Turn the Tuning control or MULTI control to select

the transmission frequency.

• The frequency selected on this VFO will be

used for transmission.

6 Press [NB/T/ 7] to turn the Tone function ON if the

repeater requires a subtone.

• “T” appears.

• Refer to “Selecting a Tone Frequency” for

more details on the subtone {page 32}.

•To quit the Subtone function, press [NB/T/ 7]

twice.

7 Press [A=B/ SPLIT] (1 s).

•“ ” appears.

8 Press [A/B / M/V] to go back to the original

reception frequency.

9 Press Mic [PTT] to transmit.

• The VFO changes to the other VFO to transmit.

• Each time you press [A/B / M/V], the reception

and the transmission frequency are swapped.

10 Press [A=B/ SPLIT] (1 s) to quit split-frequency

operation.

•“ ” disappears.

The data that you select in steps 1 to 8 can be stored

in memory. Refer to “Split-Frequency Channels”

{page 51}.

Note:

◆

When operating through a repeater, over deviation caused by

speaking too loudly into the microphone can cause your signal

to “talk-off” (break up) through the repeater.

◆

To check the tone frequency stored in a memory channel,

recall the desired memory channel, and press
