I am trying to listen to Champion EMS ( http://www.championems.com/ ), and am having NO LUCK. I have found some of the frequencies in the database, but I program them in and have no luck... It doesn't show them as being trunked, but I would imagine they are. They are based in Longview Texas, but they have trucks and opperate in 10 counties all in East Texas. Anyone have any advice, or is anyone able to pick them up?
