Fig 1. Carrier controlled repeater
This is the most basic repeater application. It will start the retransmision of the
received signal as soon as the receiver detects a carrier on the receiving
frequency. The transmitter will continue to transmit as long as the carrier is
present. After the carrier has gone, the transmitter will continue to transmit a
predifined "hang time", usally 10 seconds. This parameter could be set in the
F800 personality programming. The F800 needs no line panel for this
application. Warning! Carrier controlled repeaters are not legal in all
countries. Check with the regulations in your country.
