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
local repeater reference.

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