Total aircraft 20 - with positions 4

[g4ea5]

Hello, I just changed my sdr receiver on my raspberry pi setup but now I am getting very few aircraft positions for example: Total aircraft 20 - with positions 3

with my old rtl.sdr I was getting 90% of aircraft with positions.

What is strange though...

the following link shows aircraft with very few positions http://192.168.1.110/dump1090/gmap.html

but on the website if I filter out my radar it shows 90% with positions https://www.flightradar24.com

What could be causing this?

Thanks

After a bit of research I can now answer my own question. it appears that filtering your own radar on the website still shows aircraft being tracked by other radars, so the lack of positions must be down to the quality of the sdr I am using, I was using one of the oficial silver rtl.sdr v3 receivers which finally gave up after 2 years of service. The new one I put in place was one of the cheaper 10 euro rtl sdr.
