VOX switch
How about programming a PIC. Can't get a lower parts count than that!

I am hoping that someone could help in finding voice activation switch IC.
I did find one or two very old references to a Motorola MC2830P, but have
a
feeling that it is discontinued as I was unable to find any information on
the Motorola site.
I have found a few circuits on the web, but was hoping someone here might
have used something that they would recommend. Something with a low
parts count, and might work with an inexpensive computer microphone or
a headset microphone meant for hands free telephone conversations.
It only needs to be momentary on. Some sort of gain adjustment or
background filtering would be valuable.
any leads?
thanks
