Mine seems to be reliable. Seems to pick up relevant traffic. Ignores
airliners way up in the flight levels and I have had it ignore aircraft
passing at very low altitudes such as powerline patrols. Maybe the
software ignores them or they were too low for their transponders to be
interrogated. Can be annoying at during the launch at contest sites as
the towplanes are continually causing it to bleep.
