Okay, I have to ask because it's driving me crazy and I ended up locking them out. Who in the world is "Echo" in Denver? I keep hearing "Echo Field Team, Echo SOC, Echo this and Echo that" on 07-157. It's obviously some sort of training and I'm thinking it's OEM, but I have no idea. They sound like a bunch of CBers and it's getting ridiculous! THey are training with PD at different substations and the FD. I don't remember any training postings. Anyone have any idea?
