When a new narrowband radio receives a transmission
from an older wideband radio the speech may sound loud
and distorted – simply adjust your radio volume for best
performance.
When an older wideband radio receives a signal from a
new narrowband radio, the speech may sound quiet -
simply adjust your radio volume for best performance.
Depending on how close your receiving radio is to another
transmitting radio, there can be interference from the
transmitting radio if it is using a channel adjacent to the
channel you are listening to. simply try going up or down a
few channels from the currently selected channel.
the above situations are not a fault of the radio but a
symptom of operating wideband and narrowband radios
in the same bandwidth. this possible interference will
decrease over time as the population of wideband radios
ages and decreases.
Further information and updates are available from the
Australian communications and media Authority (AcmA)
at www.acma.gov.au and the ministry of Economic
Development (MED), Radio Spectrum Management at
www.rsm.govt.nz
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 cH 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.
