I would like to request the Coverage Graph to differentiate between ADS-B and UAT.
This way one RPI with two receivers can be deployed rather than a receiver for each.
Thank you!
Best regards,
Fred

The two are not mutually exclusive. I have both running on one RPI.
I do like the idea of having separate coverage graphs.
I do know both can be on one RPi. I built two RPi systems because I wanted to determine if UAT even made sense. I don’t get great numbers for UAT but that is what I expected.
Now that I know the UAT performance, I would like to put both receivers on the same RPi and it would be nice to see coverage for both separately.

Does pTracks
not do what you want with respect to coverage?
For me, 978 only screenshot (crappy weather yesterday with winds and rain and today is mostly cloudy, so not much traffic). 24 hours worth:
Not sure how easy it is to set that up if you have 1090 and 978 on the same box.
I wouldn’t know how to off the top of my head.
In my experience it would be useless. There are some planes that have both ADS-B and UAT active and fly at ADS-B altitudes (30-40,000 ft). Those can be tracked via UAT at about 80 miles away.
However, most of the UAT-only planes are flying much lower and can be tracked only to about 20-25 miles away.
The random “long range” dual ADS-B/UAT aircraft would draw a range that is not relevant to actual UAT reception.
PS: Look the picture provided by @markrrichardson above. There are two planes that are tracked at a distance of about 80 nm and their altitudes are about 40,000 ft. That’s not an UAT altitude, they are dual transmitting. The rest of the planes seem to be true UAT, but they are limited to 30 nm (which is better than what I usually get).
I have not looked at the link you sent.
My first thought, is where is the data coming from? If it is from my receiver on my LAN, then it only provides some data. Using the Flightaware website tells me my system is working because Flightaware is receiving data. Unfortunately, nothing seems to be able to tell me my receiver is degrading in some manner which is of interest.
Regarding aircraft sending UAT and ADS-B, an altitude filter may help. Still, the signal was received at a further distance on 978 so filtering is not that important.
A more ideal plot would be rotatable 3D. See tracks from any angle. For UAT tracks, the high altitude would be obvious. For regular airline traffic, it would be probably a bit ordinary. For military aircraft, it could be quite interesting.
I watched an F14 stopping in at Hill Air Force Base years ago. As I watched, the wings swept forward as the jet was entering the landing pattern. It was very cool to see! If I saw that maneuver on my display, I could easily visualize what is happening.
