I worked at Boeing for 20 years.
I've known a couple folks who worked there, not a great place in their book but a steady paycheck.
I dont know what frequencies the brits use for cell phones.
Easy to check if you would be so motivated. I understand 2.4 is the predominant standard all over the world. There are plenty of other examples of cell phones disturbing helis on the RR site, over 10 years of incidents, many in the US.
I think your tech is all wet.
Lol. Now I know you don't know what you're talking about. He does all my client's avionics installs, has been at it 30+ years like me. He was hand-picked by the company prez where he works just for his knowledge and skills, always in the know on new products and practices. He's the best I've ever seen, and I trust my life to his work.
I will not respond to any more of your posts
Well then, my work here is done. (Joking) Not trying to offend, but there are other folks out there with experiences different than your own. You should keep an open mind.
There have been plenty of crashes with folks using 2.4, many of which had nothing to do with 2,4 itself, probably a bad installation, dumb-thumbs, etc. The troubling ones are the sponsored pilots with seemingly bulletproof installs, jet and heli guys with great installs, but seemingly impossible failures. Some have gone back to 72. Those failures are the troubling ones. There are also incidents reported of flying sites near power lines where 2.4 had the highest crash rates.
