I bought a Zastone D9000 Mobile radio for mt truck and my HAM problem. lol. But it has a same band and cross band repeat function i was wondering if anyone had used this or something like it to make a GMRS repeater? i would mostly want to use it while on camping trips and ATV outings. Im pretty sure i need a Duplexer but im just looking for someone else who had done it before i drop the money.
