I'm playing with my PFB (on ground near big airport) and while I'm getting good Mode A/C/S hits out to 5NM, I have yet to get an ADS-B return. Is there some special setting in the FLARMcfg file that's needed to enable ADS-B?






Hi Kirk,



In Glendale I see ADS-B targets but not nearly as many as transponder

alone. A few of the airliners approaching KPHX on the MAIR FIVE show

as ADS-B equipped but most are not. The ADS-B targets I see are

usually arriving/departing KDVT. Not surprising that bizjets would

have it but airliners not. Quite possible that the ADS-B targets I

see out of KDVT are avionics flight test aircraft as there are several

based there.



email me if you want some screen photos.



I know that Boeing recently certified for ADS-B Out on the 777 so

expect the others will tag along slowly.



I'm using the brick and Butterfly display and have not included any

commands for port enabling or activating protocol version 6. I have

pushed put my ADS-B and PCAS altitudes way above the defaults though.



BTW in watching the local traffic I think I've identified 2 potential

software bugs in display ver 3.0 when running in "selection" mode.



1. If a target 3 character identifier is displayed, then that

identifier remains associated with all subsequently displayed targets

until the display (only) is reset.



2. With 2 ADS-B targets and a PCAS target, and the PCAS target being

the selected target, when the PCAS target drops out then no target is

selected. Would have expected one of the remaining ADS-B target to

become selected.



I'll continue to look out for these, although I think I have enough

supporting photos.

Andy, I noticed today the same issue as you described in no 1, but mostly with PCAS alerts. In other words, PCAS alert will show the same identifier as the last flarm alert I received hours ago, and that glider was nowhere near me anymore.
Other than that, PCAS seem to work very sporadic, and mostly alerts after the traffic had already passed. Not good.
Is there a place where we can enter bug reports?
