My vario has one radio and two networks to serve. Every second it has to decide which network to listen to and when to transmit, and that decision affects who you see on the map. Bench results: if the vario listens to ADS-L for the whole second, FANET reception drops to zero; if it stops listening to ADS-L, it receives 40 to 140 % more FANET frames; if the ADS-L listening window is cut from 550 to 300 ms, the share of seconds in which another maker's transmitter is heard falls from 61 % to 34 %.
