Not necessarily. It might be caused by local RF interference on the channel that XPS chose. That interference might not be present everywhere. I'd imagine that if those people were to check the band with a frequency analyzer or a WiFiSpy2, they'd see something out of the ordinary on the 2.4 band. |

That is a very interesting point you are making. I have always suspected right from the beginning that XtremeLink has a problem with interference and is unable to rectify the problem in certain cases.
I
always had glitches around my house or in my garage with XtremeLink. I also have a video showing the same weird stuff in the local schoolyard using the prescribed range test procedure which in the early manual was with antenna off. Out at our flying field I got a good range test with XPS but was too skittish to fly it.
On the other hand I have
never had a glitch with Spektrum anywhere, even in the exact same places I got them with XtremeLink. I have even done a range test with the airplane in my garage with just enough of the tail showing to see the elevator and rudder move then going outside with the transmitter with no clear line between antennas and still got a good range test.
Bottom line is Spektrum works when XtremeLink doesn't. Your theory may be correct: I may have some weird 2.4Ghz energy around my house. If that is the case
I have proven beyond doubt that in difficult environments Spektrum works when XtremeLink doesn't!
Here is the infamous schoolyard video. The range test procedure in the early manual called for 100', antenna off,
prog button pushed. In the video I elevated everything on an empty cardboard box with nothing around. But I
did not push the prog button! So
even at full power it failed the range test in perfect conditions!
