If you imply that my being correct somehow implied that I'm rude... then so be it. I am FAR more helpful than most "people" here! When someone is wrong and corrected with facts yet still want to argue I'm not obliged to help any further. In this case, all important info was submitted. A little effort from people to educate them selves is all it takes. And most often that is appreciated by those that freely off the education! But when ya drag the horse to water, and he still wont drink.. its time for the glue factory!
There are FAR too many superstitious habits and beliefs that are passed around here like candy! And equally, far too many that fall for them! Crossing frequencies is one of them. Ive flown with 4 other P3s and an Inspire all in the air while we sat in metal chairs with out phones in our pockets. All with no issues. Ive flow with dozens of other planes in the air at the local field... ALL on 2.4gig radios. And Ive races with dozens of cars.. all on the same bands. NEVER is there an issue. And Ive been doing all that over the past 40 years!! Just like thousands walk down the street talking on a cell phone and NEVER do you get cross-talk. THAT is the reality. I again, I have no obligation to spoon feed it to anyone.
