we traveled further north from Houston. The highest GMRS traffic areas encountered were through Phoenix, Albuquerque, Oklahoma City, Tulsa, Kansas City, St. Louis. Ohio ,Penn and New York really bad. Also noticed a lot of trucker traffic along the long interstates. They like to hang out on 18 and 6.. I talked with a few truckers, they all seem to have both CB and GMRS radios and they chit chat on both. Many of them saying they prefer GMRS. Not a single Trucker i talked with had a GMRS lic and most said they wouldnt even bother with getting one.. I would say 70% of the traffic i listened to, didn't use a GMRS lic call signs. But i did notice the Traffic in parts of Ohio, all of Penn and New York did use call signs and many using phonetic alphabet. Just like the CB, you get all the foul mouth chatter in most areas. I could not use the scanner function during most of the trip, else it would drive you nuts.. I did program my radio to scan my 4 favorite ch's and those kept pretty busy.. Also used many repeaters through the trip and most of them worked pretty good.. Repeater traffic seemed most prevalent in parts of New Mexico, Oklahoma, Ohio, Penn and New York. GMRS traffic was definaly pretty busy for most of the trip and having the GMRS mobile radio kept Highway boredom from kicking in..
