A useli method of giving the operator of a port- able or mobile radio feedback on the radio's state would be to make the PTT switch, or the whole body ofthe radio or microphone, vibrate. This could be done by using the same type of vibrating motor that are used in vibrapage pagers. They are small and typically draw only 1-5 mA.
