OPERATING THROUGH REPEATERS Repeaters, which are often installed and maintained by radio clubs, are usually located on mountain tops or other elevated locations. They generally 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 communicating 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 be accessed. For details, consult your 6 local repeater reference. OFFSET PROGRAMMING FLOW 1 Select a receive frequency. 2 Select an offset direction. 3 Select an offset frequency (only when programming odd-split repeater frequencies). 4 Activate the Tone function (if necessary). 5 Select a tone frequency (if necessary). TX: 144.725 MHz TX tone: 88.5 Hz RX: 145.325 MHz 22 TX: 144.725 MHz TX tone: 88.5 Hz RX: 145.325 MHz If you store all the above data in a Memory Channel, you will not need to reprogram the parameters every time. Refer to "MEMORY CHANNELS" {page 28}.
