My set came from Anker Electronics in San Diego circa 1985. My GRA-6 needs only 2 D-cells and a 45 volt battery ( I use 5 9-volt batteries in series). But I digress…, On Squelch: The PRC-25 is considered to be a member of the “VRC-12 Family”, AKA “New Family” radio systems. It is made from about 8 feet of 30 gauge magnet wire wound on a high value resistor as a form.
