Hi, my brother in law has had a Connex 4400 turbo laying around for several years because he couldn’t figure out how to convert it over. I’ve checked CB tricks and everywhere else I can think of and can’t figure it out either. The radio came with a module but no instructions. I think I figured out which set of one to plug it into but still can’t get it to transmit in the correct frequencies. This radio has the Ranger EPT360015C board in it. Thanks
