Ian Melville:
Do you mean RTL-SDR was not plugged into the RPi ? I thought the RTL-SDR was the receiver.

Not sure what this is in response to ?
I dont think this is related to the thread title
Re: Demodulator is <x>sec behind
can you clarify your point a little more, I don't understand I'm afraid

I think you are asking why the OGN traffic disappears from your display?
What range are you from a Groundstation when this happens ?
Are you simply on the 'edge' of reception from the ground station ?

Lee,
   Sorry if i have misunderstood your Original Question I should have posted a New topic.!
Yes all the glider traffic appears and disappears all at the same time, all the glider sights with traffic at the same time. It is as thought there transmitters are all tuned off at the same time. I still receive ADSB, and Mode C,S in there formats are still displayed and do not disappear from screen. Or in-other words while displaying all traffic, Gliders, ADSB, Mode S,C only the Glider traffic disappears. I can be at different range when it is happening. I first noticed it being south of Brighton, Not sure of distance to Burn, Pocklington, Ruff without my map to hand. I did put it down to being out of range but it seems to happen when closer to a gliding site too. ( I still put it down to a range issue, It was just when you asked the Question above it made me think.

Presumably something to do with the dns not syncing NTP properly. Had a search on the OGN Forum and found this thread. Don’t know if it helps - a bit beyond my level.
