I pick up ground signals when at the airport, but never previously from my home which is a distance away and no direct line of sight with anything on the ground. I only pick up around 1000ft and above, and I am aware 896EXX are ground and should not be picked up where I am. I am also aware that ground signals go to 60,000 but are pinged from the airport, therefore something else must be causing these spurious c/s, hex/ reg mix ups as it has not happened in the previous six years. I am getting 3400 in my daily log way above the 2000-2200 average I got pre May and it is mainly 896XXX aircraft that are effected. The radar screen is not affected just the drop down log as is the case with Diddyboy. If a globe precedes the a/c it is real but my log and reporter can show three aircraft at same height same c/s and different hex and reg/ Very strange!!
Maybe somebody is on to us! Ha ha

PS also believe that all ground equipment must now ping which was not the case previously out here
