Hi All,
I am running piaware 7.2 on raspberry pi 3 and its works fine so far but I curious if there any benefit if I use raspberry 4 ?
I also have old PC with Xeon E3 1280 that collecting dust did use this PC with ubuntu 20.04 better choice ?
Just information here my daily report
No advantage in using a 4 over a 3.
Again, not a better choice, it will just use a lot more power to give the same results.
Thank You Sir, You help me save a lot of time and money
If your feeder isn’t broken don’t fix it. Use the Pi 4 for something else, and put a lightweight Linux distro on the Xeon PC if you want to try to use it for something. I recommend MX Fluxbox or antiX.
No
i made this move a year ago, but finally no advantage at all
Only if you want to upgrade later to an Airspy it might help
Why is that ?
I mean why if I use airspy (R2 or mini ?) I need more horse power in my CPU ?
I just run my generic RTL-SDR for about 35 days I more concern about range so LNA with a good BPF (band pass filter) combine with a good antenna is my prime consideration for now, but I not a stubborn student I really like to learn for other experience.
here my range report.
and here my location surrounded by mountain and hill
Yes, more CPU power can improve reception. And the Pi 4 is using USB 3 where the Airspy benefits as well.
However it is possible to run the Airspy even on a Pi 3
The range cannot be improved if you’re already on your max limited by your environment.
First i would go to heywhatsthat.com and check what is your theoretical range.
Then compare it to your current range and identify what can be done
Hint:
If you are using readsb instead of dump1090-fa as decoder, it does have a nice feature showing the current range outline. You can create an overlay from heywhatsthat and have a direct comparison.
That’s easy and does not need money or lots of work
here my quick visit to heywhatsthat.com but no idea yet how to interpreted it
The topic of this thread reminds me the question my wife often asks me 
:
useless ?
I disagree 
btw thanks for Your very active and support to this “useless” hobby.
Seem to be that my wife and your wife are somehow related…
The blue line indicates your max range for high level flights. That’s the max you can get, independent from your equipment.
If you achieve already that range, there’s not much you can do to improve that (except flatten the earth)
The website default is 30000 ft for the blue line, 10000 ft for the yellow line.
I am glad my wife is happy, the hobby keeps me of the streets
I absolutely agree about that my wife do not comment as long as her card not rejected.
Today I learn two new thing
should we start a adsb widow wife’s support group ? maybe as a seperate forum ? 
no no no no thats the last thing I want to hear
