Interference from noise (a very strong one) on the 2.4G frequency probably will never be encountered, unless somebody purposely wanted to do it.
There is loa t of noise/interference on 2.4Ghz. You (RC) are sharing the same band with cordless phones, bluetooth and wireless computing and more. Does anyone use a bluetooth PDA, wireless router or cordless phone near your field? (and how would you know without searching houses and every car that drives by) They can all interfere with your 2.4Ghz gear. Guess what, they have priority over your plane as afar as the FCC is concerned. They can file complaints against you but not vice versa. I won't even mention my original Amana RadarRange that we use over three times a day (I could be crashing your planes a few miles away with that noise generating cyclotron).
All this nonsense about 2.4Ghz having no interference is just that...nonsense. Yes, FM does have problems with EMI/RFI, so does 2.4Ghz. As for as Spektrum, Futaba Et Al; scare tactics sell new products even if those new products are just as prone to problems.
I can't wait until the next generation of RC radio tech, everyone will be saying how bad 2.4Ghz and for a few hundred or thousand dollars everything will be perfect if you just buy the newest expensive offering from...
