TX677 Instruction Manual

EMERGENCY CHANNELS
The ACMA has allocated channels 5/35 for emergency use only. Channel 5 is the
primary Simplex Emergency Channel. Where a channel 5 repeater is available, you
should select Duplex on channel 5.
Note: Channel 35 is the input channel for the channel 5 repeater. Therefore
channel 35 should also not be used for anything other than emergency
transmissions.
TELEMETRY CHANNELS
ACMA regulations have allocated channels 22 and 23 for telemetry-only
applications and have prohibited the transmission of speech on these channels.
Consequently the radio has a transmit-inhibit applied to channels 22 and 23.
In the event that additional telemetry/telecommand channels are approved by
the ACMA, these channels shall be added to those currently listed where voice
transmission is inhibited. Currently, transmissions on channels 61, 62 and 63 are
also inhibited and these channels are reserved for future allocation.
