Can you operate1090 and 978 receivers on a Pi3 B+ together

I have a Pi3 B+ operating with the blue 1090 receiver using the rubber duck antenna (their kit). Can I add the Orange 978 receiver to this Pi 3 B+ splitting the antenna feed between the two receivers without changing anything in the software on the micro SD card or changing setting in the setup? In other words is adding the 978 receiver basically a plug and play addition? Thanks Al

Assuming you’re using the ADSBx Pi image (should have been on a microSD card included in the kit), a couple of simple steps in the browser UI are required to enable 978 - go to http://adsbexchange.local/ and under “Assign SDRs to services”, “Choose an SDR serial number for dump978 service (978Mhz)” (when the new SDR is plugged in, it should appear in the menu there) then under “Configure Receiver/Location”, set “Enable 978 UAT? (requires second SDR)” to “yes”.

Thanks for you quick detailed response. I have the 978 receiver on order along with both a dedicated 978 rubber duck antenna and a splitter in case I choose to buy an external antenna in the future I will let you know the status once I get the hardware. Thanks again. Al

I am operating both the 1090 MHz and 978 MHz receivers with a Pi 3 B+. When I check locally I see I am receiving aircraft info but how can I tell which signals come from which receiver. That is are they both contrubting? Thanks Al

There’s a separate local map for 978. There should be graphs for it in graphs 1090 too. Both of those are accessible from http://adsbexchange.local/ Or you could look at your ADSBx Anywhere Map - the 978 ones will appear in the table on the right with a green background (“UAT / ADS-R”).

Don’t be surprised if you don’t see many/any sometimes, depending on your location, receiver performance (978 signals are typically from low altitude aircraft, so more easily blocked by terrain, etc), especially with indoor rubber duckies.
