converse on the newer channels 41
–
80.
The newer narrowband radios will be able to
converse with all older 40 channel wideband
radios on all channels 1 to 40 as well as the
newer channels allocated from 41 to 80.
The mixing of narrowband and wideband
radios in the same spectrum can cause
some possible operating issues of
interference and varying levels of received
volume.
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.
ACMA regulations have allocated channels
22, 23, 61, 62 & 63 for telemetry only
applications and have prohibited the
transmission of speech on these channels.
Consequently the UV-81C will skip these
channels
22, 23, 61, 62 & 63

storing or using your radio where
temperatures are below

The same amount of spectrum is available;
however, radio transceivers can now operate
in a narrower bandwidth and hence use less
spectrum. These radios are generally
referred to as narrowband or 12.5 kHz
radios. By using 12.5 kHz channel spacing
instead of 25 kHz, the 40 channels originally
allocated has now expanded to 80 channels
thereby doubling the channel capacity and
relieving congestion in the UHF CB band.
Original 40 channel wideband radios will
continue to operate on the original 40
channels, however they will not be able to
