8 ENHANCED COMMUNICATIONS
FM REPEATER OPERATION
When using FM mode, you may access a repeater to
enjoy long distance communications. Repeaters,
which are often installed and maintained by radio
clubs, are usually located on mountain tops or other
elevated locations. Generally they operate at higher
ERP (Effective Radiated Power) than a typical
station. This combination of elevation and high ERP
allows communications in FM over much greater
distances than FM communications without using
repeaters.
Most repeaters use a receive and transmit frequency
pair with an offset. In addition, some repeaters must
receive a tone from the transceiver before it allows
access. Repeaters are available on the 29, 50, 144,
430/ 440 MHz, and 1.2 GHz bands (TS-2000/
TS-B2000 Optional). For further information,
including repeater frequencies, consult your local
repeater reference.
This transceiver provides the following three methods
for programming two separate frequencies:
• Using the Split-Frequency function {page 31}
• Programming an offset (29, 50, 144, 430/ 440 MHz
and 1.2 GHz bands)
• Storing in a Split-Frequency channel {page 59}
Note:
◆
When programming two separate frequencies using two 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.
PROGRAMMING AN OFFSET
When using the 29, 50, 144, 430/ 440 MHz or 1.2 GHz
band (TS-2000/ TS-B2000 Optional), selecting a single
frequency and an offset is another method for
programming two separate frequencies. Unlike the
Split-Frequency function, this method requires only a
single VFO.
Note: If you store offset settings in a memory channel, you need not
reprogram each time. Refer to “MEMORY FEATURES” {page 58}.
■ Selecting an Offset Direction
1 Select a receive frequency.
2 Press [0/ SHIFT/OFFSET] to switch the offset
direction.
• Select whether the transmit frequency will
be higher (+) or lower (–) than the receive
frequency.
• “+” or “–” appears to indicate which offset
direction is selected.
• To program the –7.6 MHz (430 MHz) or
–6.0 MHz (1.2 GHz) offset on all E-types,
repeatedly press [0/ SHIFT/OFFSET] until
“=” appears.
If the offset transmit frequency falls outside the
allowable range, transmitting is inhibited. Use one
of the following methods to bring the transmit
frequency within the band limits:
• Move the receive frequency further inside the
band.
• Change the offset direction.
Note:
◆
You can only change the offset direction while in FM mode.
◆
While using an odd-split memory channel for transmitting,
you cannot change the offset direction.
■ Selecting an Offset Frequency
To access a repeater which requires an odd-split
frequency pair, change the offset frequency from
the default which is used by most repeaters. The
default offset frequencies are as follows.
dnaB epyt-K sepyt-EllA
zHM441 ± zHk006
zHM044/034 ± zHM0.5
± zHM6.1
zHM6.7–
zHG2.1 ± zHM0.21
± zHM0.53
zHM0.6–
As for the 29 and 50 MHz bands, the default offset
is set to 0 MHz (Simplex). Program the desired
offset frequency for these bands.
1 Press [FUNC], [0/ SHIFT/OFFSET].
2 Turn the MULTI/ CH control to select the
appropriate offset frequency.
• The selectable range is from 0.00 MHz to
59.95 MHz in steps of 50 kHz.
3 Press [FUNC], [0/ SHIFT/OFFSET] again to
complete the setting.
All E-types only: If you have selected “ =” for the offset
direction, you cannot change the default (–7.6 MHz or –6.0 MHz).
