im testing the GNS 5890 with adsbSCOPE 2.6 untill i get my microADSB. the GNS is using the supplied antenna in the box. it varies beetween 1 and about 1500 depending on the time of day. 3794 FR (frame rate) on Friday. weekends are slower. also depends on where you are. im south facing. if you have GNS and adsbscope you'll notice after the flights have landed they drift as FL 0 off the map untill they are reready for use again. ive seen flights land (decrease in ALT then contuine off the map as drift) see video

maybe i could come down to YSSY and try it there. help me out maybe its my antenna.
cheers
