I've been listening to scanners for about 20, 25 years and that is the first time I have heard anything like that, I often get the F15's out of Lakenheath declaring an emergency or a code 1 as they call it but they are so cool and calm about it, (I mean a code 1 is quite serious) but it doesn't seem to phase them, some years ago I was listening to a, I think it may have been a C5 Galaxy taking off from Mildenhall someone reported something fell from his a/c on take off and it turned out to be one of his wheels but when he was asked to return to give a undercarriage down fly past the control tower, where they had a Galaxy crew waiting to have a look, his only word was OK, that's when they noticed the missing wheel but he carried on his flight to Germany and landed safely, top man. I think they may have had a clamp down on the signals they allow us to hear, I can see them in the sky, quite low yet I see nothing on the map, voice transmissions also seem to be getting less and less, I know some of it is F-15 or F-35 traffic by there callsign's and mannerisms but I wouldn't bet my life on it. I also have photographs of all the fire tenders out on the runway seeing to a F-15 landing with a hung bomb from the range, and the top man in his F-15 with the three squadron markings on his tail. I can see now you have obviously had a good look at your antenna situation, I'll stop prodding you. I had the voltage drop problem when I extended the low voltage side of a Raspberry pi power adapter only the length of my desk, was fine before but once I had done it I kept getting the little lightening symbol on the screen, it works ok extending the higher voltage side (240v) in my case but not the 5v. I think that as the power adapters are supplied they are at their optimal length. Wish you well. C
That's why Tesla's AC current won over Edison's DC system.... Yes, the wires that come with the Pi power supplies seem to be the minimum gauge to not have a voltage drop at that length. I have extended 12V lines plenty of times in the past but 5V needed heavier gauge than I expected. I only used a few inches of the supplied wire, my 20 foot extension is large gauge speaker wire, normal gauge speaker wire was too small.
Lessons, we live and learn Marty, I mistakenly re-used another piece of wire from another power adapter and learned my lesson that way, it's funny how you do something and somehow it doesn't feel right and as soon as the first lightening icon showed up I knew straight away what the problem was, I just ended up moving a 240v power point closer to the pi and went back to the original length on the low voltage side, I suppose in a way it's better, that's another point I can hide under my desk. Cheers
