I am looking at Flight data on AirData from a flight.
I had a couple of warnings about Remote Controller weak (Code 80004) and (80002) and (30002). They started at approx 2.7Km. Over sand at a beach. The signal dropped from 83% to 49% within 2m and then to 30%, Downlink data connection lost for 1.6 seconds with no further distance.
Is this likely to be interference or something more sinister?
Any thoughts?
Sorry, moved this from Droning on as posted in wrong place.
At 2.7km out you’ve probably reached the limits of CE power levels 
How high were you Keith?
Did you adjust the antennas?
By which they mean, hold the controller vertically above your head 
Parallel to a street full of hotels ozzing WiFi signals out of every nook and cranny?
Or were you flying out towards the horizon?
What else is in area on Google sat view?
Exactly my thoughts, loads of caravans.
Possibly Wi Fi boosters or similar.
I was running parallel to the beach approx 200m off the beach.
The point I lost contact was close to a certain well know holiday resort.
Whilst standing on one leg?
And herein lies your answer 
(coupled with CE power limitations)
As Busby used to say…It’s good to talk.
Clears thing up in my little brain. Once an engineer …
Hi, how do you see the drone at 2.7 k I have trouble seeing my Phantom at 500m.
Wife in the car with a radio following it in constant contact.
Interesting idea Fred, Is it difficult to get a special permission for beyond line of sight operations. Does the wife drive the car and look in sky at the drone?

She was watching the drone at all time I believe! 
Bvlos operation is specialist flight.
Fred, let’s cut to the chase mate.
What you are doing is both illegal and dangerous.
It just makes all the bad press about drone flyers more credible.
If your wife is driving, using a handheld radio and constantly watching a drone then she is also acting both irresponsibly and dangerously. I hope that I don’t meet her on the road.
May I politely request that you stop this type of flying as it is wrong.
I am amazed that people on this forum have not made comments similar to mine.
I speak as a holder of a PFCO and my A2 C of C.
I spent nearly 40 years in the emergency services and people that thought they could ignore the rules of safety kept me in a job.
Have a good Xmas.

Sent you a PM before you wrote this explaining exactly that!
@angliafire we are not the Drone Police
Chris, appreciate your comment but I have admitted I was wrong performing the flight. It was my first ‘real flight’ with a ‘real drone’, I was curious.
I am currently in the middle of my A2 CoFC and now understand a lot more. I do not intend to fly illegally and even the choice of altitude and site for the flight shows I was not acting completely without thought. Without knowledge, maybe. However, ignorance is not innocence
Personally I would have sent a PM and asked whether the person concerned was aware of their wrong doing and then educated them rather than doing it on an open forum but that is just my humble opinion.
More aimed at the accuser.
If we didn’t have the NDPZ in place every single post would go the way this one has. Facebook and/or other forums are available for the Keith Laird comments
