Joe: Probably one of the cheapoest ways to do this would be to get an el cheapo rptr controller and connect it to a VHF rcvr. The company can then buy DTMF mikes for their radios. If it were me, I'd set up a separate VHF freq or the same freq with a different PL for the gate actuator. I prefer the seprate freq so they won't broadcast the gate actuator code all over the world.

The company has a fleet of VHF radio equipped vehicles. They want to pull up to a site, enter a touch-tone sequence on the mike, and open a security gate at the site. I could kludge together something, but would rather find something commercially available. Anytime I have kludged something together, I have ended up having to repair it for longer that I expected. Something with a VHF receiver, TT decode and relay contact output would be great. Any ides if this is even made commercially? I know that some fire/ambulance departments use a similar idea to open and close the firehouse door. Some also have the ability to control traffic control lights on their way to a situation. 73, Joe, k1ike
