Could you post what coax, amp, filter and Antenna you use?
I have to restart my dump978 every 6 hours. It seems to just stop working and a restart fixes it.
My main (attic located) unit running dump978 is an Odroid XU4. It sends the data to an RPI3 that does the stats graphing and feeds FlightAware. I did see similar issues with RPI3s running dump978.
I had great success with the Hab/Nevis amp (near the dongle) and the STD RTL-SDR V2 dongle(I had to solder the bias-t connection. V3 is a software switch).
I was using it on a directional antenna and moved it to the FA Dual band antenna (and mast mounted amp) last week. Unfortunately I broke the SMA connector on the amp and had ordered two more.
For some reason they are coming to NYC (from the UK) via LA.

airspy.us doesn’t sell the 978 amp/filter. It is strange as UAT 978Mhz is only used in the USA.
This site has been dump978 only since November 13. You can see the traffic drop off when I messed it up last week.
I did get up to 1000 aircraft(best day was Nov 23) with the antenna pointed in my best direction (North West). The FA Dual band is a little higher than the directional antenna (maybe 3’) so should have a better range (I am really low. Ground level is only 30’ AMSL) and won’t be directional.
I decided it was easier to dedicate one RPI/site the dump978 and it has helped with trouble shooting. I enabled logging in dump1090 to get a better feel for the stats. Don’t do this if you also feed 1090 information as your file system will fill up quickly.
Feel free to post or PM me with any questions.
