Anyone have a pin out for the PDC "Lunar cricket?" I got it in a lot of stuff but the previous owner cut off the wires and I can't find a pin out or info on it .
Handy way to test is using one of those Mic Tester Boxes. Has built-in speaker and connections for DC power and Audio. I used to use those to test noise toys all the time. You'll just be using the connections on the sides and not any of the mic plugs on top. Shown is a Superstar T747
That's how we test echo boards, pings and roger beeps before installing into a radio. Catching a dud before it's installed saves labor and frustration. That tester has appeared with more than one brand name on it over the years.
