Tel-Instruments has identified an error in the display of ADS-B OUT data.   The TCAS Operational bit and RA Active bit were being decoded from BDS register 6,2.  In cases where BDS register 6,2 was not being transmitted by the aircraft, erroneous data was being displayed. The new software decodes these bits from BDS register 6,5. This register is always transmitted by ADS-B OUT aircraft and eliminates the possible erroneous display
