New PiAware setup for Christmas only getting other data

Got all the pieces for a PiAware setup for Christmas, set it up as per the instructions and get three green lights in FlightAware’s page, but I’m only getting data under ‘other’ no MLAT or ADS-B. It’s an indoor installation in a window with an unobstructed view of the east so I should be getting some data. We aren’t in a high traffic area, but flights show up on my SkyAware with only ICAO, Altitude, MSGS, and Age (not on the map)

Config:
Raspberry Pi, Pro Stick, NooElec 1090 Antenna.

Any tips on where to start troubleshooting?

Thanks!

Change this antenna for something else, it’s beyond bad.

Stand up the RPi so the ProStick is pointing upwards.
Place a paperclip in the SMA connector with a length of 70mm.
It should stick out of the connector with a length of 66 mm.

Bonus points for radials like show here:

Be careful with not to use wire that’s too big for the SMA connector.

Basically it’s similar to this antenna, which needs some coax and at least an SMA connector: QUICK SPIDER - No Soldering, No Connector

You can also remove the plastic cover from your Nooelec antenna and basically create the above described quarter wave antenna that way.
Principle remains the same, simple wire coming from the center conductor, 66 mm long and radials which can be a bit longer connected to the shielding (ground).

Thanks I’ll work on upgrading the antenna.

My MLAT icon has switched to Red and I don’t seem to even be getting the ‘Other’ data now. Here’s are the logs, it seems it’s having problem with ‘no ADS-B data program’?

Are you using the piaware sd-card or did you install on a Raspbian?
Did you install any other feeders like FR24?

Do this:

sudo systemctl restart dump1090-fa

Then take a look at the dump1090-fa log.
Check here on how to check and post logs:
https://github.com/wiedehopf/adsb-wiki/wiki/Debug-commands

While you are at it, the page above lists how to check for under-voltage, check that as well.

Using PiAware sd-card, changed the Pro stick over to being powered and now MLAT is green again and I’m picking up 5 aircraft the same as before with ICAO, Altitude, MSG, and age. Map still isn’t showing aircraft and no ADS-B data.

Progress is being made. I’ll have to take apart the pi to get the SD card out to change the config to allow SSH. I’ll get back in a bit with there’s any improvement after restarting dump1090-fa but the errors have stopped in the log after the power change.

Well you are not receiving any positions.
To decode a position you need 2 DF17 messages from an aircraft within 10 seconds.

You just need better reception to receive more than you see right now.
Just disconnect the Nooelec antenna and put in a paper clip cut to 70 mm.
It will perform significantly better, the Nooelec antenna is tuned to 800 MHz or something stupid.

I got two NooElec antenna’s and one has 800 and the other 1090 on it, I’m using the 1090 for the moment. This sounds like it’s as good as it gets for now until I have time to work on the antenna. Thanks for the help!

Just remove the plastic, maybe you can remove the coil by bending the wire and make it just 66 mm long and straight.

Those antennas really belong in the trash, so you might as well try something with it :wink:

google for DIY antenna. Any coax which you can use is better to what you have now.

I am using currently in my indoor setup an antenna similar to this:
