Going back to the original post, I am a bit mystified. I presume the "blue circle" on the top picture indicates the aeroplane's position - it appears to be about correctly located for Frome, thus agreeing with the aircraft position in the second image? The "blue circle" does NOT appear to correspond to the location of the UAT transmitter at SDHQ at Milbourne Port. But the location of the "transmitter icon" in the top image CERTAINLY does not correspond to Milbourne Port either - it is MUCH too far to the north west - west of the M5 and apparently somewhere near Taunton? It seems to me to indicate that, whatever the OP was picking, it was not Tim D's test transmitter?
Elsewhere (some while ago) Tim has talked about planning to move his transmitter to a better location as the SD offices are set in a valley (which compromises the reception range at typical GA altitudes, but Tim has not made any announcement of the relocation actually taking place? What's the score on that front, Tim?
The only other explanation I can imagine is that (since AFAIK the UAT data stream includes the co-ordinates of the transmitting station - and indeed, if not, how could the Garmin in the original post know where to display its icon for the transmitter position?), for some reason (intentional or otherwise) the Milbourne Port transmitter is set up in a way that spoofs its own position?
