[Repeater-Builder] Astron reset circiut
I'm building the Astron overvoltage reset circuit that is listed on the Repeater Builder. How can I confirm that the circuit is working properly ? What is the test procedure ? Thanks ! Jeff Corkren/W5PPB Raymond, Mississippi Your use of Yahoo! Groups is subject to the Yahoo! Terms of Service.

Jeff, With any O/V circuit all you need to do is lift off the lead that goes to the + output and insert a 12 volt lamp between that point and the + output. Now get yourself a variable power supply and connect it to the sense lead to the O/V module. You must not connect the sense lead to the existing P/S at this point Increase the voltage to the module until the lamp lights and you're done ! measure the "trip" voltage and make what ever adjustments that you think are necessary.

Spin the potentiometer under the board that mounts onto the output caps, this should get your voltage to accidentally go too high - turn it down before you do the reset or it will not go back on for more than just a blink. > Jeff Corkren wrote: > > I'm building the Astron overvoltage reset circuit that is listed on > the Repeater Builder.
