The Protector is a small circuit board that is installed between any 12-volt radio and a 12-volt power source. The power source can be anything from an AC line operated supply to a 12-volt battery at field day. It will protect the radio against over voltage and from reverse polarity. It will also provide a delayed start up, just in case you forgot to turn the radio off before connecting it to power. Even though the Protector will protect any load connect to it against reverse polarity and over voltage conditions it will do so without blowing fuses. In either case, once the problem is fixed, the Protector will once again allow power to be sent to the load. The Protector is easy to build and requires no adjustments or set up. By design, operation is totally automatic and requires no user inputs. It is completely transparent to the user. If you know what end of the soldering iron gets hot, you should be able to assemble the Protector in less than an hour. All the parts mount on a single double-sided PC board about the size of a playing card.
