Ive had my RPI setup for a few years and I used to have the VRS program running to allow me to get a plot to see how far I’m getting signals.
Did something change on how to do it? FA discussion about it
That was the only one I found and its 8 years old.
Why are you not using the alternative map produced by tar1090 and the readsb decoder (alternative to dump1090-fa) provided by @wiedehopf
With this combination you can generate an additional range plot on your map.
More information here:
The tar1090 can produce exactly same map with dump1090-fa as well as with readsb. Replacing dump1090-fa by readsb is not necessary to have tar1090 map.
I have dump1090-fa installed on all my RPis, and in addition installed tar1090 to produce alternate map. Now I can view both dump1090-fa’s Skyview map and tar1090 map.
However, replacing dump1090-fa by readsb is necessary if you want the range plot that @foxhunter referred to and that @sniperdude says he wanted in his post.
Thanks. I did not know that readsb is necessary for range plot on tar1090.
The reason is that I never tried to have range plot using tar1090. Instead I get / view range plot using planefinder datafeeder:
(1) At planefinder website at https://planefinder.net/coverage/receiver/97686 (Click on “Coverage Map”)
(2) In Local Network at 192.168.12.24:30053/viz.html

Actually, so do I 
It is necessary if you want to have a range plotted. That’s what the thread opener wants to achieve.
Planefinder can do it as well, but you will need a different feeder installed. Not everyone wants that. I am running a second site locally only without any feed. It’s in our RV just for getting the information which aircraft are currently above the camp ground.
