We are unable to test this properly but believe that it broadcasts over little used AM signal somewhere on the dial or low band FM. Interior battery compartment and wiring look really clean and we expect this will work but consider it not working for purchase purposes.
11″ microphone without the extendable 15″ antenna that extends from the bottom. Great MJ decal above the push to talk button with MJ name sticker over it at an angle. Silver paint on top has worn to Black in many areas. Mic is overall very good–.
