Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of
the United States may be punishable by a fine of up to $10,000, imprisonment for up to
two (2) years, or both.
1.10 OPERATING TIPS
The following conditions tend to reduce the effective range of two-way radios and should be
avoided whenever possible:
•
Operating the radio in areas of low terrain, or while under power lines or bridges.
Obstructions such as mountains and buildings.
•
In areas where transmission or reception is poor, communication improvement may
sometimes be obtained by moving a few yards in another direction or moving to a higher
elevation.
NOTE
1.11 CITIZENS BAND OPERATION IN AUSTRALIA/NEW ZEALAND
Use of the citizen band radio service is licensed in Australia by ACMA Radiocommunications
•
(Citizens Band Radio Stations) Class License and in New Zealand by the Ministry of Economic
Development (MED) General User Radio License (GURL) for Citizens Band Radio, and
operation is subject to conditions contained in those licenses.
In Australia, except in an emergency, a CB transmitter shall not be operated on UHF
•
emergency channels 5 and 35 and no voice transmissions are permitted on data
(telemetry/telecommand)
telemetry/telecommand channels are approved by the ACMA, these channels shall be added
to those currently listed where voice transmission is inhibited.
Always listen in on a channel (or observe a channel-busy indicator) to ensure it is not already
•
being used before transmitting.
UHF CB repeater operation must avoid operation on locally used repeater input channels
•
(which will be in the range of channels 31 to 38, and channels 71 to 78 when they are
authorized) or locally used repeater receiving channels (which will be in the range channels 1
to 8, and channels 41 to 48 when they are authorized), unless long-distance communication
via the repeater facility is specifically required. NOTE: In Australia, channel 11 is the
customary calling channel for establishing communication and channel 40 is the customary
road vehicle channel.
•
Possible operational issues during the changeover from 25 kHz to 12.5 kHz channel spacing
that may cause system performance degradation is if a WB channel gets placed 12.5 kHz
away from a NB or WB channel. In this case, adjacent channel interference would increase
and performance would degrade. There would also be some level of performance
degradation if a NB transmission is received on a WB channel and vice-versa. L3Harris
equipment meets the emission mask which minimizes any impact.
