Alright so first off I'm pretty new to the whole two-way radio scene, so any answers may have to be dumbed down haha, alright so I bought 3 Motorola spectras off ebay, all the same model; D43KMA75ABK. Now when I hook them up and turn them on all is good, they recieve very clearly, but they're receiving a billingual weather channel, basically an automated transmission, I was wondering how I change the channel it is set to so I can keep in contact with my two friends to whom I'm giving the other radios, we're a mobile crew essentially and being that talking on cell phones while driving is illegal and they've cracked down on it big time in my city, these radios would be a great asset. All input is appreciated.
