I upgraded to 2.0 last weekend and since my reception is about 20% lower than with previous version (from 105k down to 70k). I am using dump1090 mutability version. Is this expected? Should I revert to fa dump version? did I miss an update for the mutability package?
There were no changes to the decoding side in 2.0, it was piaware only.
Do you have local stats showing a drop in received messages, or is it only the position reports as seen on the FA website that have dropped?
Also check that dump1090-mutability is, in fact, still running and you didn’t revert to some other dump1090 version on upgrade/restart
The piaware health messages seem to indicate that you’re running dump1090-mutability but using faup1090 to translate to the FlightAware format - is that right?
There were some changes to the rules that faup1090 uses to decide when to forward traffic, so that very stale positions are not forwarded - that might be the cause of the reduced position rate (actually, it’s just not sending useless data any more)
Thanks for the feedback. I eventually when up in the attic the day before last night, to check on the antenna, and found out that the antenna had slept down the PVC tube. I have pushed it all the way up the tube, and I am back in the 100k positions per day.
FWIW, this confirms that 1/2 length part of coco antenna out of the attic bring 20% more positions than the whole antenna in the attic.
