But, if I did this, it would not be an "off the shelf" product and I would end up being the support repair for the units. There may be several of them.

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.

Subject: [Repeater-Builder] OT: Need to find a product to develop goodwill
at a tower site(s)
Hello to All,
I am starting to develop a future ham repeater relation with a tower site(s)
owner and recently got a request for something unusual. 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
