OPERATING THROUGH REPEATERS Repeaters are often installed and maintained by radio clubs, sometimes with the cooperation of local businesses involved in the communications industry. Compared to simplex communication, you can usually transmit over much greater distances by using a repeater. Repeaters are typically 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 considerable distances.

OPERATING THROUGH REPEATERS
Repeaters are often installed and maintained by radio clubs, sometimes with the
cooperation of local businesses involved in the communications industry.
Compared to simplex communication, you can usually transmit over much greater
distances by using a repeater.
Repeaters are typically 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 considerable distances.
REPEATER ACCESS
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 in order to gain access to the repeater.
For details, consult
your local repeater reference.
■
Selecting an Offset Direction
The offset direction allows your transmit frequency to be higher (+) or lower (–)
than the receive frequency.
1
Select your desired band (A or B).
2
Press
[F], [REV]
to select an offset direction.
•
Each time you press
[F], [REV]
, the offset direction changes as follows:
