Using Repeater Channels
UHF CB Repeaters are used to retransmit or replay your signal. Repeaters will extend the range of your radio
and overcome the shielding effect caused by solid obstructions. In normal Simplex operation, your radio transmits
on one particular frequency and receives on that same frequency. If there is a barrier that partially blocks your
transmitted signal, the probability of another radio receiving the signal is very slim. Hills, tall buildings, metallic
structures,ꢀetc. tend to act as a screen between radios.
The Signal coming from your radio is received by the Repeater Station and then retransmitted at the same time
on another channel. This operation is called ‘Duplexing’.
For example,
CH01 on Duplex Mode will receive on CH01 but Transmit on CH31
CH02 on Duplex Mode will receive on CH02 but transmit on CH32 etcꢀ
If you transmit on CH01 Duplex mode, you are actually transmitting on CH31, the repeater station down-converts
your signal and retransmits on CH01.

Maintenance
Preventive Maintenance: The following system checks should be made every six to twelve months:
Check the Standing Wave Ratio(SWR)
Inspect the tightness of all electrical connections.
Inspect the antenna coaxial cable for wear or breaks on the shielding
Inspect the tightness of all screws and other mounting hardware.
Troubleshooting: Should the unit malfunction or perform poorly, follow these procedures;
If the transceiver is completely inoperativeꢀ
Check the power cord and fuse.
If there is trouble with receivingꢀ
Check the VOLUME control setting. Be sure the SQUELCH is adjusted properly. Possibly the radio is over
squelched.
If there is trouble with transmittingꢀ
Check that the transmission line (coaxial cable) is securely connected to the ANTENNA connector.
Check that the antenna is fully extended for proper operation.
Check that all transmission line (coaxial cable) connections are secure and free of corrosion.
Memory Backup: A built-in capacitor protects the channels stored in the UH012 memory after the
DC power cable is disconnected.
