For reliable operation, please try the following recommendations:


  1. Keep the microphone close to your mouth.  The closer the better.
  2. Start with the VOX sensitivity high.  If stray sounds activate the transmitter, turn down the VOX sensitivity.
  3. The sensitivity level you obtain in step 2 will determine how loud you must talk to initiate the VOX.  The lower the sensitivity, the louder you must speak.



Please note:


  • The VOX circuit takes approximately 1/2 second to turn on the transmitter.  Because of this slight delay, it is normal to lose the first word of a transmission.   If you blow into the microphone, etc., to activate the transmitter, then you will not loose the first word.
  • If you pause to long when speaking, the VOX will turn off.
