Solved A lot of interference probs

[short_nathan]

I am a member of an RC plane club that has had constant reports of radio interference in the last few months in its flying field. It is right by a river and at the other side of it, there is a new neighborhood being built. There is also a very big pile of dirt that was made because of the construction. Does anyone have any idea of what could be causing all that interference?

Been my experiences that significant interference is caused by the people flying the other planes, and huge amounts of interference reported when stuff glitches because someone turned on the transmitter just for a second to test something. Ever have a chance to be alone out there and see if the problem replicates? Unless the site has a telephone repeater building, or you are in the path of microwave beams, there shouldn't be the unusual problems.... 8 ft tall chainlink fences are sometimes an issue however, as are metal structures. In my 60 years flying, it's usually someone else doing stoopid things they shouldn't or not admitting you were showboating

I don't think the river & dirt pile are causing any issue.

Is it the same one or two guys having the trouble? If so it may be their equipment. Whenever I "get hit" the first thing I do is check my Rx. I usually remove the case and look closely at the antenna lead especialy as s goes through the case. If there is a small nick in the antenna lead, that is the cause of the trouble. You can often save the Rx just by replacing the antenna.

If it is more than just a handful of people, it may be something else. Maybe there is a lot of Wi-Fi in the area.

That could be it, I remember having interference when flying. I do remember that there was a pilot flying a plane with one of those transmitters with huge antennas that are known for causing lots of interference.

It could be the WiFi, because most of the club is expiriencing issues.

Wifi and other telephone related interferences is location sensitive: happens in the same place and is repeatable. Say you fly over a rock pile and it immediately noses straight down but you always recover just in time. Anybody flying over that rock pile has the same problem with sudden whacky direction changes. That would be a symptom of land based interference. Everyone crashing only while George is flying? His radio system is spewing out off frequency side channels. Some times you get interference when more than 5 people fly, that is bandwith issues. Finding the ACTUAL cause is hard without a visual picture of the band displayed on some scope reciever

Otoh, I have found most people complaining about interference have lousy radio Installations or super cheapo equipment

Right next to the edge of the field I fly in are two cell phone masts. They are active and of course also operate on 2.4 but I have no trouble flying really close or even over them. It hard to imagine a static water body or a pile of dirt could generate more potential interference than active radio masts.
