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.

TX: 144.725 MHz TX tone: 88.5 Hz RX: 145.325 MHz

Offset Programming Flow

■ 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 VHF band is 600 kHz no matter which market version; the default on the UHF band is 5 MHz (TH-D7A) or 1.6 MHz (TH-D7E).

The reverse function exchanges a separate receive and transmit frequency. So, while using a repeater, you can

manually check the strength of a signal that you receive

directly from the other station. If the station’s signal is

strong, both stations should move to a simplex frequency and free up the repeater.
