It appears that you know what you or the company wants so a suggestion on making it work. Pager receivers work well in this type of application, and they can be had now for nearly free. Attach it to a DTMF board of your choosing, and you have what you ask for. It's obvious that the company has already looked for what they are asking from you, but can't find it. It may also be a test of your technical ability to solve simple problems. I have seen this before when the group doesn't know ones abilities.

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 >
