I am using Debian GNU/Linux 13 (trixie).

Here is my rbfeeder.ini file:

AirNav ShipTrax Discussion / ShipXplorer AIS dongles keep failing

« Last post by davemcallister on May 08, 2026, 07:07:13 PM »

Hi everyone,

I have had two ShipXplorer AIS dongles fail on me in the past 6 months.  The first one failed last December after years of use, so I replaced it.  The next one worked fine until yesterday, but now it is no longer recognized by the computer.  I have tried different USB ports, multiple reboots, reinstalled Powershell, etc. with no luck. 

These are the same symptoms that the first dongle displayed.  I tested the first dongle on the computer and the behaviour is still the same.

The Powershell command line I have been using is:

cd c:\Radio\AISCatcher
.\AIS-catcher -d:0 -gr TUNER 45.0 RTLAGC off BIASTEE off -a 192K -v 10 -u 127.0.0.1 10110 -M DT -N 8100 LAT 49.7 LON -123.1 REALTIME on SHARE_LOC on FILE stat.bin BACKUP 10


and the error I get is:

usb_open error -12
Error: RTLSDR: cannot open device.
UDP: close socket for host: 127.0.0.1, port: 10110

It does not show up in Device Manager - when it is plugged in, Device Manager re-enumerates, but no new devices appear.

The dongle is isolated from the antenna with a lightning arrestor and a multicoupler, and none of the other equipment connected is having issues, so a surge isn't the cause.

Has anyone else experienced this?  Is it possible that a Windows update has done something to my access to the ports?  Or is it just bad luck?

Any suggestions would be welcome.  Thanks in advance!

Rod

For info ICAO has done away with individual codes for motor gliders and have instead allocated GLIM for all motor gliders. 

I am working my way through changing the codes over

Hi

What OS are you using on the Pi and can you post a copy of your ini file with your credentials redacted

I've only just noticed that the ICAO code for the Quest Kodiak (KODI) has officially disappeared and been replaced by these:

K100 - Daher Kodiak 100
K900 - Daher Kodiak 200 and 900

Hi everyone,

I set up my station 7 days ago and I’m reaching out because I’m having some trouble with MLAT.
Even though my dashboard shows that I am synchronized with about 30 nearby stations, my report says I have sent zero MLAT packets. The ADS-B feed is working perfectly, but MLAT seems stuck.
I have already correctly configured my Latitude, Longitude, and Altitude in the dashboard settings, so my location is precisely set. I also checked my hardware and everything is stable (Raspberry Pi Zero 2 W, solid power supply, and good temperatures).
Could this be a backend issue with my station's UUID or the synchronization between my feeder and the MLAT server?
I’m a total newbie at this, so please bear with me. Thanks in advance for your patience and help!
Best regards, Enzo (Station EXTRPI723871)
