The Airspys are connected via USB3 to their respective Pi4s. The two Airspy R2s are fed from the same antenna with a Minicircuits 3dB splitter....
Tried 12MHz, that worked. Tried 20MHz, that worked too. 24MHz seems to be a no no, as we say here. Thanks again wiedehopf
Yes Airspy R2 with GPS reference (I know it isn't required, however it helps others find their required PPM offset. Currently running at 24MHz, I...
Thank you wiedehopf I ran those scripts. Now Stradishall_01 and Stradishall_201. Still pretty much the same.
I've been feeding ADS-B Exchange for a few years however I hadn't checked it recently. Flightaware on Pi4 running 64bit Buster. adsb-exchange...

Nice map. I see that Suffolk is now in the North of England.
OK If I look at the timing at my two feeds from a feed with a high sync count and a low PPM error, then the difference is more consistent between...
I understand the PPM offset is the pants per million difference in frequency from other feeds that I am synchronised, with but what causes Sync...
