Disconnection/Data Feed Not Working


#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

#2

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.

#9

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