* The primary use for these channels is repeater operation using 750 kHz offset. Channels 1-8 inclusive
are used for mobile reception and channels
31-38 for mobile transmission. Note that additional channels 41-48 and
71-78 are also available for repeater operation to supplement channels 1-8 and-31-38 respectively
as approved by the ACMA CBRS Class Licence in Australia and the MED GURL in New Zealand. In
addition, any designated repeater channel may be used for simplex operation in areas where it is not
used for repeater operation.
† Speech telephony shall be inhibited on these channels.
‡ At the time of production Channels 61, 62 and 63 are guard channels and are not available for use.
Channel 5 and 35 (paired for Duplex repeaters) are reserved as emergency channels and should be used
only in an emergency.
CTCSS and DCS will not operate on these channels.
A list of currently authorised channels can be obtained from the ACMA website in Australia and the MED
website in New Zealand. Channel 11 is a calling channel generally used to call others and channel 40 is the
customary road vehicle channel.
Once contact is established on the calling channel, both stations should move to another unused "SIMPLEX"
channel to allow others to use the calling channel.
Channels 22 and 23 are for Telemetry and Telecommand use, voice communications are not allowed on
these channels by law.
Channel 9 and above are the best choices for general use in Simplex mode.
