Have someone monitor your signal on another radio. Transmit and speak into the mi -
crophone at normal level. If the received signal is quiet then the mike gain control will need
to be adjusted. If the signal is loud and distorted then it will need to be turned down.
These adjustments should be done using a comm. test set.
Have another radio transmit a test call and monitor the audio quality. With the volume
control turned to the 3/4 position the audio should be loud and not distorted. Distortion
could be caused by the choice of speaker. A 4 watt speaker is recommended as a minimum
power rating. Set the squelch and have the station transmit, the squelch should break
crisply and without delay.
Note
Do not transmit on 121.500MHz, as this is the international distress frequency.
