Operation Via Repeater; Setting Of Repeater - Quanzhou 9900 Operation Instructions Manual

Operation via Repeater

The repeaters are generally installed and maintained by radio club or sometimes, in cooperation
with local communication system enterprises.
Compared with simplex communication, you can generally transmit over a farther distance via the
repeater. Repeaters are generally installed at mountain top or other higher position and can operate
at ERP (effective transmission power) higher than that by general radio stations. High-placed
installation in combination with high ERP can achieve communication over a farther distance.

Setting of Repeater

Most of the repeaters use receiving/transmission frequency pairs with standard or
non-standard frequency offset (different frequencies for transmission and receiving).
Moreover, some repeaters can be utilized only when receiving voice frequency from a
talkie walkie. For details, please consult the owner of the local repeater system.

lower (-) than the receiving frequency.
