Operation

Selecting a Channel

Turn the Rotary Channel Selector to select the desired channel.

For your reference a list of the available channels, corresponding frequencies and guidelines for their use is printed on page 10. For Australia, Channels 05 and 35 are reserved for Emergency Calls.

Transmitting

The uh012sx uses the 40 UHF-CB Channels (Channels 22 and 23 are for telemetry and telecommand applications. Transmit is inhibited on these channels).

Select the desired channel. Press the microphone's PTT button and speak normally into the microphone. Hold it approx. 7cm from your mouth. Release the PTT button to end the transmission and listen for a reply.

Using Repeater Channels

UHF CB repeaters are used to retransmit or relay 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.

Repeater Station.

Station (Duplex).

The signal coming from your radio is received by the Repeater Station and the re-transmitted 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 etc...

If you transmit on CH01 Duplex mode, you are actually transmitting on CH31 the repeater station down-coverts your signal and retransmits on CH01.
