Disconnection/Data Feed Not Working

FlightAware ADS-B Flight Tracking
1

Over the past week, I have experienced loss of data on the Skyview page. The Feeder shows that it is checking in, but I am getting no data. Wi-fi connection is strong. The setup has been running flawlessly for 7 weeks, and just this past week the problem has come up. Any ideas?

Thanks

Check the antenna connection.
Loose connectors or water in them.

3

Forgot to mention - that was one of the first things I checked. I’m using the Flight Aware Antenna, which has been great. Connection to the dongle and antenna are good.

4

Is the N connector on the coax a 50 per 75Ohm version?
The 75 Ohm version has a smaller pin and can make intermittent contact with the antenna.

5

It’s 50. I also am into ham radio and I have a bunch of it.

6

Ham too.
Maybe a problem with the dongle or USB connection or cable.

There was a recent post about a Ham wiping out his ads-b receiver with his transmitter. The outage looks to be too long for that.

7

I may have found the source of the problem. A bad USB port in the Raspberry Pi. So far, so good - no drops. Fingers crossed.

8

I use decent USB 3.0 pigtails with ferrite chokes just to be sure(and to have enough room for multiple dongles).

Good luck.

Thanks for your help. I’m going to order pigtails now.
