this has been bugging me for a few weeks now. theres a spot i fly at pretty regularly, nice open lake with no real obstacles around, and my Air 3 keeps getting these signal warnings and dropping to like 1-2 bars on the RC2 controller even when im not that far out. maybe 400 meters or so. everywhere else i fly its totally fine, ive had it out to well over a km with no issues

first thought was interference but i dont know what would be causing it at a lake specifically. theres a parking lot nearby but thats about it. i always do a compass cal before flying somewhere new but i havent done one there in a while. could that be it? or is there something about water that messes with the signal i dont know about

not crashing or anything, RTH kicks in fine, its just annoying and i dont fully trust it out there anymore

water can definitely do weird things with 2.4 and 5.8 ghz signals, especially if theres a lot of surface reflection going on. but honestly my first guess for that kind of localized issue would be to check if theres a cell tower or some kind of antenna infrastructure near that parking lot. those can create interference hotspots that feel totally random. try switching the RC2 to a different frequency band manually and see if that changes anything, sometimes auto mode just keeps picking the worst option

had something similar at a reservoir near me and it turned out there was a wifi repeater or something on a nearby dock that was absolutely hammering the 2.4ghz band. switched to 5.8 and it was night and day. also worth checking if you have any FCC vs CE mode settings you can tweak depending on where you are, makes a difference in transmit power

the compass cal thing is probably not your issue if youre not getting actual compass errors, that usually shows up as something else entirely
