GRT Avionics

I have the Discovery receiver (and a TT22 transponder) and it has been functioning as advertised. However, I flew two legs yesterday and did not receive ADS-B weather on either leg. I did receive a few traffic targets, but I am unsure if they were ADS-B or the old Mode S TIS radar uplinks through the TT22.

In the Menu pages (I don't recall the exact pages or line titles) but this was displayed: ADS-B METARS 0, ADS-B Weather 0, ADS-B Traffic 2. Or something similar to this.

Another local aircraft flying was receiving ADS-B traffic and weather with different equipment, so there must not have been an outage.

Any ideas to troubleshoot?
Thanks.

Had the same problem today, June 1 after installing latest Nav database. Traffic is working but no weather. Problem is on my Sport EX EFIS and also on my iPad with FltPlnGO. I sent an email to Jeff a few minutes ago.

I'll add that I had same issue in WingX on the iPad connected via WiFi to the Discovery.

Jeff replied that the NAV database couldn't be the problem and that perhaps there was a system outage. Flew today, two days later, and everything is working correctly. Must have been a system problem but curious that Clam was flying with another aircraft that didn't experience a problem.

I flew today and ADS-B weather worked as advertised. So, must have been an outage. I’m thinking my buddy who reported it working on the day of concern may have been receiving XM weather service.
In any case, the universe is back in balance.

I have 2, maybe 3 reports of weather issues in the last few days (including one possible case with a different kind of receiver), but I don't see any other reports of weather issues in other forums or an outage reported. If anyone happens to have a DEMO recording while up in the air that day maybe I should take a look at one file to see if there's anything that stands out.

Jeff, I have it in the plane. Will send it to you Thursday.
