I'm brand new at listening to scanners and I could use a little help. I have a uniden bc75xlt, it's not much but it works. I'm a freelance photographer for several newspapers and I like to get all the info i can whether it be a fire, car accident or whatever. i'd like a few tips if someone out there is nice enough to help out. First off can someone please explain to me what the "red" channel is and what is the frequency? Also, is there away to listen to the digitized channels that are now in use? And the last thing can someone please give me all the good frequencies for central wisconsin?
