Moved pi3b+ PA v5 to pi4b+ PA v6 - seeing 978 errors

FlightAware ADS-B Flight Tracking
1

Just upgraded to 6.1, but at the same time I replaced the pi3b+ with a pi4b+. Looking for assistance to make sure it is configured properly.

Details:

  • pi4b+
  • FlightAware Pro Stick Plus v1.0

This is a fresh install of piaware, following these instructions. Then moved the site ID over.

It looks like the dump978 portion is not and keeps restarting. I did the v6.1 install without the FlightAware USB receiver plugged in (it was still running on the pi3b+). Hopefully that did not cause issues.

You have a PiAware SD Card image as your command prompt pi@piaware:~ $ shows, but you followed procedure & settigs for a package install.

As you have not plugged in dump978 dongle, this is a case of “using only 1090 Mhz”. To stop piaware from continously trying to start dump978-fa, use following procedure:

Note:

The setting “using1090 only” is default setting of piaware SD Card image, but this setting was removed when you upgraded using procedure for package install. Above noted 3 commads will restore the default stting.

Looking at your stats page, you have never received a UAT plane or position.
Do you actually have a 978MHz receiver ?

(you can’t run both bands on one receiver)

Thank you abcd567 and GeckoVN, I appreciate the help!

I realize that naming the new pi “piaware” adds confusion. The pi3b+ I just replaced was using the SD card image and the new pi4b+ is using the package install. That is just the host name.

The second point helps answer a question I have had for a while now. So, I would need a second dongle on the system to also receive 978MHz signals. That makes sense, but I was not sure previously.

I ran the commands successfully to run 1080MHz only and will review what is needed to run two receivers.

As you have confirmed that although you have package install, but have chosen hostname as “piaware” (which misguided me), to run both 1090 MHz and 978 MHz receivers, you need 2 dongles, and following steps:
