The DSP-223 keys up the UHF Base
Station Transmitter in Analog Mode.
The UHF Transmitter will transmit
different CTCSS tones to the
UHF Receiver at the High Site.
The UHF Receiver (RXB) Receives
one of multiple different CTCSS tones
and changes the channel of the
VHF Transmitter (TXA) to a corresponding
channel with the same CTCSS tone.
This VHF transmitter goes out to different
repeaters all on the same receive
frequency, but with different CTCSS tones.
The UHF Receiver (RXB) also keys up the
UHF Transmitter (TXB) to repeat the signal.
ANALOG LINK
ANALOG LINK
The UHF Transmitter (TXB) Transmits
the received VHF and UHF signals back
to the UHF Base Station Receiver
and other UHF stations.
The Multiple Link Controller is
programmed to change
VHF Transmitter (TXA) channels
based on CTCSS.
