When you fire up your DX6, it searches for, selects and locks onto clear channels. (There are 80 channels in the 2.4GHz band.) And because international regulation of the band is very strict, your radio will neither sustain interference from - nor cause interference to - any other 2.4GHz device worldwide. And that applies, of course, to its simultaneous operation near other 2.4GHz RC radios as well.
