I've used OpenCPN
this summer during two months of sailing. My VHF
is connected to my PC.
The AIS alarm
is set to 2 miles and 30 minutes. I'v found a little problem (really not blocking).
When the CPA/TCPA is inside the limit an alarm
window appears which can be aknoledged, and the window doesn't re-appear again...
EXCEPT, if the CPA/TCPA is close to the limit (2 miles / 30 minutes) and go inside then outside then inside again of this limit.
- going inside, the target becomes red, the alarm appears : acknoledge
- going outside, the target becomes green, and I think is removed from a table or list of dangerous targets.
- going inside again, the target becomes red again, and the alarm re-appears although it has been acknoledged a few seconds before.
It can occurs many many times, because each time a target becomes dangerous, OpenCPN
has forgotten it has been already acknoledged.
By the way, all is very all right, many thanks to OpenCPN.
