I get constant notifications of my own transponder; yesterday probably 100 times, not kidding. I will have to unplug LX9000 from the PowerFlarm as it is not possible to use it as the PowerFlarm warnings just take over the screen.

I had exactly this problem at Minden. LX9000 and Mode S. The problem is that the powerflarm configuration file has the wrong / no transponder code in it. Reviewing the powerflarm configuration file carefully should fix it.
