The DSP-223 keys up the UHF Base
Station
T
ransmitter in
Analog Mode.
The UHF
T
ransmitter will transmit
dif
ferent CTCSS tones to the
UHF Receiver at the High Site.
The UHF Receiver (RXB) Receives
one of multiple dif
ferent CTCSS tones
and changes the channel of the
VHF
T
ransmitter (TXA) to a corresponding
channel with the same CTCSS tone.
This VHF transmitter goes out to dif
ferent
repeaters all on the same receive
frequency
, but with dif
ferent CTCSS tones.
The UHF Receiver (RXB) also keys up the
UHF
T
ransmitter (TXB) to repeat the signal.

The UHF
T
ransmitter (TXB)
T
ransmits
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
T
ransmitter (TXA) channels
based on CTCSS.
