Was PWMurg down today?

Yes it looks like the 1090 USB has failed again. How could you tell? -and- Thanks!
Redoing config now, 1st attempt failed with 'USB not named'(?)
is there a command to pipe the tty output to a text file?

[PaulSS]

I don't think anything has failed as I am seeing traffic normally. I just think it's something at the OGN map thing that may be amiss. The only reason why I knew they were purple agin is because I happened to have a look......no other indications.

Paul / Neil,

Not sure about the 'purple', though I think it is the equivalent for 'blue' stations as 'red' is to 'green', but the OGN stations going red (or purple) isn't particularly uncommon. It can mean there is an issue with one of the OGN servers, but IME it doesn't in any way affect the operation of or rebroadcast from our ATOM stations as we only feed data to the OGN - we don't take data from them (or at least not from their servers).

Regards

Peter

That's 2 weeks in a row that logging in to the Pi has shown/reported the 1090 SDR isn't working, fixed by rerunning the config.
I may buy a new SDR.
While checking it out I noticed PWEGLK is offline.

This morning. Station appeared to be working OK, METARs and showing aircraft, although I got a local (192.etc) response on my PC bt not on my phone. Ran config twice:

Is this a problem?

Hi Neil,

Funnily enough (not funny really, sorry), I experienced the same thing recently when I reconnected my long running ATOM after having temporarily removed the Pi/Bridge unit to use the antennas and dongles to set up another station.

Replaced my original unit after I had finished, booted it up and re-ran the config with the dongles in Upper and Lower Left (which is where they always were) and got the same 'device 0 with serial number 1090 cannot be found' message.

Checked the dongles were in the correct slots and properly located then rebooted - this time all fine but still had to reconfirm 'use dongle 0 as 1090'. Rest of config went as expected and (AFAIK) the station has been running fine since (now well over a week). Oh and mine is still on a daily timer - off overnight.

Not sure how much this helps, but obviously something we need to keep an eye on.

Regards

Peter

I haven't touched a thing and yet this is the OGN map today. As I said before, I think this is a snag at the OGN end.

Thanks Peter
It MIGHT just be a glitch the first time config runs and not be an indicator of a degraded station. It still sees loads of ADSB traffic (I'm near Heathrow) which is via the 1090. Now I'm learning to read the 'Front page' better I can see MLAT targets that are detected  locally. I'll keep an eye on it. Fof for the last 2 days has kept GA/Glider traffic numbers very low.
I will try and extract a pattern from the behaviour.
