Hi,
I don't know why but since a few days I got some black/white strip square in my hourly received report. http://myip/dump1090-fa/ don't show any aircraft. My total position normally varies from 210k and 254k but since that problem 33k and 50k, I know it's normal if no radio is detected and orange in status page. My setup is roof mounting since over 6 month without any problem. All my connections and connectors look good. I use Piaware 3.5, Flightaware 1090MHz antenna with PI2 and NooElect DVB-T dongle.

What I can check to know what's going wrong? Log? params? Reinstall piaware 3.5 image?

Thanks

Looks like hardware problem.

It may be due to a defective dvb-t. If you have another dvb-t, try it.

Another possible reason is power supply. Either it has insufficient capacity, or of poor quality or gone defective.

Also check antenna and antenna connections.

Although you are in Canada, the long summer sun may be overheating some components.
