I don't have the ability to run tests on GPSd pre-release (at least likely
before you release it).  However, most of the previous versions, including
3.10 show a problem detecting very low rate AIS input sentences
Interesting.  We're not getting this report from Roy Barkas or any of our
heavy AIS users other than you.
There's a way you can diagnose this. Run at -D 10. This will show you the
actual input character by character.  If you're getting runs of garbage
that cause the packet getter to lose sync, that will be easy to see.

I will try and get a trace - I'm not near the devices for at least a few days.

Do please note my specific repro steps that the device has *nothing* on the input for some many seconds at the start of detection (and quite intermittent sentences thereafter - not 100% sure this isn't the actual issue). I dont think I see a problem if the input rate is quite high (that's my workaround, wait until there is plenty of AIS input and replug)
