The squelch is used to eliminate any annoying background noise when there
are no signals present.
Make sure to first select a channel not in use before setting the squelch in your uh073sx UHF-CB radio. Think of squelch as a gate. Turn [SQ] fully
clockwise. This raises the "Squelch Gate" so high that only the very strong signals can get through.
Turn [SQ] fully counter clockwise until you hear a
hiss. This opens the "Squelch Gate" so that
everything gets through noise, weak signal, and strong signals.
To set the "Squelch Gate" to the desired level, turn [SQ] counter-clockwise until you hear noise. Then
turn the [SQ] clockwise just until the noise
stopped. Now only the desired signal can get If an incoming signal is very weak there is a possibility that you will have a choppy or broken reception, due to the sensitivity of the squelch. In this case, simply rotate the [SQ] clockwise
until the weak signal is heard clearly. TO TRANSMIT AND RECEIVE
The uh073sx uses the 40 UHF-CB Channels. For your reference a list of the
available channels and corresponding frequencies is printed at the end of this 1. The maximum RF transmit power of uh073sx is 3 Watts.
To switch to low power, press . LOW appears on the LCD.

The display shows BUSY when a transmission
is being received by your radio.
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 (i.e. a Tall Building) that partially blocks your transmitted signal, the possibility of the other radio receiving the signal is very slim. Valleys, metallic structures, etc., tend to act as a screen between radios.
Standard Operation without the aid of a Repeater Station Normal Simplex Operation Transmitting on CH 01 Operation with the aid of a Repeater With Duplex operation, the signal coming from your radio is received by the Repeater station and then re-transmitted at the same time on another channel.
Your uh073sx is designed with duplex capability on Channels 1 to 8. When any of these channels are set to operate in duplex mode during transmission, the uh073sx automatically sends the signal at a frequency 30 channels above the original in order to access the repeater station. After transmitting, the radio reverts back to its original operating frequency.
1. CH01 is on Duplex Mode - will receive on CH01 but Transmit on CH31 2. CH02 is on Duplex Mode - will Receive on CH02 but Transmit on CH32, etc….
Refer to UHF Channel & Frequencies table on page 20.
Eg. CH01 is being used in your area for repeater use.
Press momentarily . The DUP icon appears.
Press again to deactivate the duplex operation.
uh073sx will return to simplex operation.
Check with your local retailer for available repeaters. SCANNING
The uh073sx has two types of scanning; Open Scanning (OS) and Group
Scanning (GS).
Scanning allows you to search for active channels programmed in the OS or GS memory.
To initiate scanning; 1. Assuming the unit is on CH17 when switched on.
2. Press scan and scanning starts. Scan icon flashes during scanning.
Open Scan (OS) Mode (the absence of GS icon indicates that the unit is on
Allows continuous scanning of channels stored in the Open Scan (OS) memory.
If an active channel is found, scanning will stop on that channel.
The factory has preprogrammed all the 40 UHF channels into the Open Scan channel memory. However, you can change or customize the channels by following the steps on programming Scan Channels on page 15. Example: CH40 becomes active
If the received signal cease, the unit will wait for at least 3 seconds for the signal to return, otherwise scanning resumes.
To skip the active channel, press mem momentarily. Scanning resumes.
To deactivate SCAN, press scan or
If SCAN is deactivated while in an active channel, the uh073sx will stay on that active channel. If no other channels are active, the uh073sx will reinstate the starting channel. Group Scan (GS) Mode
Allows you to monitor a Priority Channel while scanning.
To use GS Mode Scanning, press the icon appears on the GS Scanning checks the Priority channel activity regularly.
If GS Scanning is initiated when there are no channels programmed in GS memory, an error tone will be heard and scanning will not start. If the Priority channel becomes active the radio will stay on that channel for as long as the signal is present. If the received signal ceases, Priority scanning continues after 3 seconds.
If scanning stops on a channel which is not a Priority Channel the uh073sx will continue monitoring the Priority Channel for activity while listening to the active one. To deactivate SCAN, press the scan or
If SCAN is deactivated while it is turned to an active channel, the uh073sx will stay on that active channel. If none of the channels are active, the uh073sx will reinstate the Priority channel. Programming Scan Channels
1. Select which Scanning Mode you wish to use OS or GS Mode.
OS is indicated by the absence of the GS icon. 2. Select the channel you want to store by pressing 3. Press and hold mem for 1.5 secs. to store. MEM icon appears and two
