About repeaters
A repeater is a fixed radio station which receives signals on one frequency
and transmits the same signals on another frequency. It works in duplex
mode. The basic use for a repeater is to enhance the covering range for
mobile radio stations working in two-frequency simplex mode. The traffic
mode for such system is referred to as "Semi duplex".
The F800 can be used as a stand alone repeater or a repeater connected to a
control system. Repeaters connected to control systems such as MRS3000 or
MRS5000 are used to work as combined bas and repeater stations. A stand
alone repeater is a repeater that has no wire or link connection to a radio
exchange or a control unit. However, it could exist as a component in such a
network.
Technical specifications
The F800 repeater has 20 W output on all frequency bands. It contains a
duplex filter to be able to receive and transmit simultaneously. See the
technical data sheet for details! The repeater will retransmit everything it
receives with flat frequency response between 300 and 3000 Hz. A deviation
of 3 kHz in the receiving signal should result in a 3 kHz deviation in the
transmitted signal. The maximum deviation is limited to 5 kHz.
