OPERATING THROUGH REPEATERS

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 over much greater distances than communications without using repeaters.

Most repeaters use a receive and transmit frequency pair with a standard or non-standard offset (odd-split). In addition, some repeaters must receive a tone from the transceiver to allow it to access. For details, consult your local repeater reference.

PROGRAMMING OFFSET

First select an amateur radio repeater downlink frequency on the A-band or B-band as described in “SELECTING A FREQUENCY” {page 7}.

■Selecting Offset Direction

Select whether the transmit frequency will be higher (+) or lower (–) than the receive frequency.

Press [F], [REV] to select the offset direction.

•“+” or “–” appears, indicating which offset direction is selected.

•To program –7.6 MHz offset on the TH-F7E (430 MHz only), repeatedly press [F], [REV] until “” appears.

TX: 144.725 MHz

TX tone: 88.5 Hz

RX: 145.325 MHz

TX: 144.725 MHz

TX tone: 88.5 Hz

RX: 145.325 MHz

If the offset transmit frequency falls outside the allowable range, transmitting is inhibited. In this case, adjust the receive frequency so that the transmit frequency is within the band limits.

Note: While using an odd-split memory channel or transmitting, you cannot change the offset direction.

OFFSET PROGRAMMING FLOW

qSelect a band.

wSelect a receive frequency.

eSelect an offset direction.

rSelect an offset frequency.

(only when programming odd-split repeater frequencies)

tActivate the Tone function. (If necessary)

ySelect a tone frequency. (If necessary)

If you store the above data in a memory channel, you need not reprogram every time. See “MEMORY CHANNELS” {page 15}.

■Selecting 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 frequency on the 2 m band is

600 kHz (all models); the default on the 70 cm band is 5.0 MHz (TH-F6A) or 1.6 MHz (TH-F7E); the default on the 1.25 m band is 1.6 MHz (TH-F6A).

1Press [BAND] to select an amateur radio band you want to change the offset frequency.

2Press [MNU].

3Turn the Tuning control or press []/ [] to select Menu No. 6 (OFFSET).

4Press [] or [MNU].

5Turn the Tuning control or press []/ [] to select the appropriate offset frequency.

• The selectable range is from 0.00 MHz to 59.95 MHz in steps of 50 kHz.

6Press [] or [MNU] to store the setting. Otherwise, press [PTT] to cancel.

TH-F7E only: If you have selected “ ” for the offset direction, you cannot change the default (–7.6 MHz) offset frequency.

Note: After changing the offset frequency, the new offset frequency will also be used by Automatic Repeater Offset.
