I departed KGSO today and the departure called saying I was reporting two different altitudes. They asked if I had two transponders aboard and if so could I turn one off. Well I don't have two. They called again and said Center was very troubled as one showed me climbing through 17,900 feet. I was level at 5500'. I went into my GRT HXr and turned off ADSB to see if that would stop the uAvionix from reporting. It worked and rest of flight they showed me at the correct altitude through my GTX327. The only unusual thing I noticed was the data flow rate on the settings page in the HXr showed a very spotty flow ... not the constant fast rate of flow from the uAvionix. Restarting for the return trip home did not reset anything.
Anyone had any issues like this?
