Can you give me a link to Northwest Emergency Service Inc unit you belong to? A google search turns up nothing. What exactly is this "ERU" you drive around? How many emergencies do you respond to in an average year and is this an Indiana state authorized emergency vehicle? I was the Overhead Team Leader from my county sheriff's department in California for 27 years. No knock on you but we always had "SAR" groups that formed to try and help the community. Most of the time they were whackers and police wannabes that got in our way and never helped anyone. It's very hard for me to imagine the area around Indianapolis being a hotbed of SAR callouts, or at least as I understand SAR.
Channel 9, at least in California, is not only useless, it's dangerous. We had a lost couple in a 4WD in a snowstorm is the mountains who actually managed to contact someone of channel 9. There as no cell phone coverage where they were stranded. We were able to make contact with them on channel 9 and, while trying to determine where this lost couple and infant were located, we had a couple of idiots who would come on with their footwarmers and cover all our traffic with a string of obscenities. We read them the standard FCC warning about interfering with an emergency operation and it did no good. We had the couple switch to different channels and the nitwits followed us. We finally got enough information between all the interference and cursing that our helicopter was able to locate them. We had a few people out DF'ing them and managed to locate one house just by the massive size of the tower and beam. Of course, we filed a complaint with the FCC but our DA wouldn't indict on a state charge since it was a federal case. Never did hear anything from the FCC about enforcement but did hear that his tower collapsed several weeks later, apparently due to faulty guy wires. Sometimes things like that just happen, I guess.
