So this is the 60$ speaker on Amazon. The tx that it comes with is a toy low powered junk. Lucky for me I was able to figure out it works on frs1 or frs2. I was able to fly over to another SAR members house and he was able to hear me perfectly from a couple hundred feet up. Actually, his house is 600 feet away and I could hear myself fairly well. Range shouldn't be a problem. Yes I know, I shouldn't be transmitting on frs with a 5w radio and maybe I can figure out some way to use ham or public service frequencies but for now I'm still in the testing phase.
