Switching the VOX Signal Source for SDV Communication
By means of softkey 'VOX' the operator can switch the Voice-operated Transmission (VOX)
signal source.
This procedure is described insect. 3.7.2.16 Switching the VOX Signal Source.
4.7.4.4
Tuning the Antenna
By means of softkey 'ATU Tune' the operator can tune the antenna. After some seconds, the
current antenna impedance is matched to the radio frequency. The operator needs to repeat
this operation in case of changing the antenna, the antenna position or the frequency. The
tune result for this frequency is stored in the radio; it is not needed to retune when returning
to this frequency or after switching the radio on again.
This procedure is explained in sect. 3.7.2.22 Starting ATU Tuning.
The tune output power does not depend on the output power setting. For tuning the
antenna a fixed output power is used to measure the current antenna impedance and
after tuning, the output power is switched back to the value configured by the user.
