Using VOX

Solution Using Transceivers, Setting the VOX, & Radio use

It is quite common for first time users to have some difficulties, although it seems quite simple, and it is, there are some tricks in getting it right. So let's go through a few pointers.

Before riding, set the system up on the bikes and practice some radio disciplines. It can help if you practice on one bike while listening on the other transceiver with the volume turned up and the leads unplugged from the side so that the transceiver speaker works. Someone else can talk back to you on the other transceiver by pressing the PTT button on the side of the transceiver. If they listen carefully they will hear the short delay after you finish speaking and before your VOX switches off and you stop transmitting. It is important that you understand this VOX delay, as it is pointless trying to transmit back to someone else if they are still transmitting. One has to have a short VOX delay so that the system reliably stays on during normal speech, which may have short pauses and you don't want a transceiver bouncing between transmit and receive, with the small losses of speech that you get in between.

When you first speak you need to draw out the first word or use a key word to get things going. I always use "OK when you get to the lights take a left, OVER" I always use OK at the start of a conversation because although the VOX is instant, transceivers have to go from standby to transmit and also standby to receive, the other end. So there is a 1/2 second or so delay. DON'T TURN LEFT may come over as TURN LEFT, so its good practice to use a key work like OK then say what you want such as OK, DON'T TURN LEFT. Its also good practice to say OVER when you have finished speaking, as if after saying OK TURN LEFT the other person replied with OK, OK, they may well have transmitted over you trying to say something like AND THEN TAKE THE NEXT RIGHT. Of course if you wait to hear OVER before giving a reply you can help avoid this, but even a well seasoned user will occasionally jam, which is when two people transmit at the same time.

Practise makes perfect and it's much easier to practice while close together and not riding and worrying about other things going on.

If your radios have an adjustment on the VOX sensitivity then you should try the settings to find the best for you.
