Hello, I'm fairly new to GMRS and primarily purchased it for superior communications to CB radio, mainly when exploring or off-roading in my Jeeps. I've got a million questions, but I'll get to them slowly, starting with this. I was scanning on my Midland MXT275 tonight and heard a conversation that was very clear between a couple towns that were not too far off. One person was in Camby, Indiana and another was in Indianapolis. I was in Danville. The furthest distance was to the person in Indianapolis, which would have been 18 to 20 miles from me. They came through crystal clear. I had my repeater setting off. (I know nothing about repeaters yet, so I haven't turned on that setting.) So I'm not sure they were using repeaters. But they sounded as good as if they were 1 mile away. Then another guy jumped in and said he was in Gary Indiana. That's easily 130 miles away! I've read that repeaters can get you 30-50 miles, depending on variables. So how was this guy getting so far? And he also sounded like he was 1 mile away. Perfectly clear. Thanks, and I look forward to learning a great deal here!
