For Christmas I was looking to buy me some winter storage security
for "Mellow Yellow" , my '82 dsl  Westy.
Checking out the local electronics stores I found that a good "Alarm"
system can set you back $400 - installed.  Hmmmm!  Is the old gal
even worth it? I thought.
        Then I recall that years ago I adapted a CB rig to transmit a
'buzz' type noise when any of the sensors were 'activated'. As far as
distance was concerned, it worked better than any device on the
market at the time.
        Not wishing to get into CB gear again, but having an FRS
system on hand; I thought... why not go with the latest technology.
Now, if I could get a relay to work an external mike input then I
would be all set.
        Looking at my 'older' FRS radio, I do not see an external
mike input but perhaps someone on the forum has done this or
something better.
        I don't need to know if the engine bonnet is lifted, the
window lowered, the engine started or any one of a dozen different
'options' available. These devices would seem to require a team of
CIA electronics experts to fully install all the wires and sensors.
In an effort to keep my Westy wiring simple, all I need is a motion
sensor inside and that is simply a plug-in device.
        Has anyone come up with a simple alarm system that will
transmit more than 100 yards and not costing an arm and a leg? If
not, I will commence my own project along these lines.
Thanks!

P.S.: I did a search of the Archives with no luck.
