Selecting the Digital Voice rate
The Digital Voice rate or DV rate is the bitrate of vocoder used for the digital voice transmission.
Higher vocoder rates will result in a more natural-sounding voice signal at the receiving station,
but it requires better channel conditions than the lower rates. A lower vocoder rate will result in
greater processing artefacts at the receiving station but can operate in very poor channel
conditions. The range of vocoder rates are available to enable the operator to choose the best
rate for best voice quality versus channel condition
The digital voice rate is shown in status area 1 of the channel screen. The Digital Voice Rate can
be changed during voice calls.
To change the DV Rate, from the channel screen:
• Press the key. The DV current rate will display in status area 1. Repeat this
process until you have cycled through to the bitrate you desire.
