I wasn't saying 900 meters was a prime example of performance. Its just that I don't think I've ever found myself more than 1km from who ever I'm talking to in an airsoft game before and even if that distance is completely covered with hills and trees the cheaper radios work just great. Its just that a local Ottawa newb was talking to me about radios and because of something he read here on ASC he thought he HAD to get a $150 UHF radio, just throwing in a voice for the better cheaper radios. A lot of people think that unless its some hugely expensive UHF radio, its useless.

My dad is a HAM operator and he actually told me he did this once by accident because of extreme humidity variations between the temperature layers, nifty. Though I haven't talked to my dad about radio stuff for years though I did hear that you no longer need to know morris code to get your license?
