Boeing727,

You got some things wrong from what I posted. First, it was B.L.E. that implied protection with his comments on collision avoidance used by devices operating in the 2.4 gHz band. I challenged that assumption, as I'm assuming you are too.

Cordless home phones operating in the 2.4 gHz band could feasibly interfer, as they do with other wireless devices. I didn't mention that per se. However, it would be a real stretch to worry about having your cordless phone out at the flying field. I would like to know how the Spektrum system protects from strong signals nearby on the same frequency? I don't think it does, but I could be wrong. An overpowering signal is just that, and wouldn't a fail safe system be the only recourse?

Yep, I've talked to hams who think they are protected in the 6 meter band. I've talked to others who say it is a mess and not worth fooling with. You are right about the attitude of the ARRL regarding the 6 meter band, and others.
