Likely cautions are GPS issues, TAWS, Heading miscompare etc. These usually last only a minute or two.
I don’t believe in coincidences but I’d like to try narrow down when and where these are occurring as there seem to be a couple of areas near Sheffield, Nottingham and DTY that I’m aware of. TIA
This may have nothing to do with 5G actually. We have found an area of NW Birmingham that is consistently jamming our GPS and we are working with Ofcom and believe we have established it
might be two elements of a new (not 5G) mobile mast that are crossing over exactly on the GPS L1 frequency. I would be very interested to learn more about your experience (before tomorrow (9 June)) if you can (by PM please). I need location, height AGL, symptoms and duration (both in terms of how long it lasts and how many days you have experienced it).
