As of auto_rx version 1.5.10, we are limiting APRS output to only radiosondy.info, and only on the non-forwarding port.
This decision was not made lightly, and is a result of the considerable amount of non-amateur traffic that radiosonde flights are causing within the APRS-IS network.
Until some form of common format can be agreed to amongst the developers of all radiosonde tracking software to enable radiosonde telemetry to be de-duped, I have decided to help reduce the impact on the wider APRS-IS network by restricting the allowed servers and ports. Michal SQ6KXY has also configured radiosondy.info to stop forwarding radiosonde traffic onto APRS-IS.

If you are using another APRS-IS server that does not forward to the wider APRS-IS network and want it allowed, then please raise an issue at https://github.com/projecthorus/radiosonde_auto_rx/issues

You are of course free to fork and modify this codebase as you wish, but please be aware that this goes against the wishes of the radiosonde_auto_rx developers to not be part of the bigger problem of APRS-IS congestion.
As of 2022-03-01, radiosonde traffic has been filtered from aprs.fi, so even if you do modify the code, you still won't see sondes on that map.

APRS-IS is a shared resource, intended for the use of all amateur radio operators, and for many years we have been treating it as a playground to dump large amounts of non-amateur traffic into, so we can see weather balloons on a map.
Instead of congesting this shared resource with non-amateur traffic, we should instead be moving to using databases and sites specialised for this purpose, such as sondehub.org

This release brings the following updates:

  • Decoders: DFM decoder should now be somewhat more robust to multiple DFMs appearing on the same frequency. This is not that well tested, so reports on how it performs when multiple sondes are present would be appreciated. - Thanks @rs1729 !
  • SondeHub: Inhibit errors relating to Z-Match filtering.
  • APRS: Removed the synchronous upload feature, which will help reduce instantaneous load on APRS-IS servers.
  • APRS: Restricted the APRS server to radiosondy.info, and the APRS port to the radiosondy.info non-forwarding port.

Other Known Issues:

  • iMet-1 serial number generation still has issues, and will result in iMet-1 sondes being assigned 3-4 different serial numbers throughout the flight. This is due to the iMet-1 telemetry repeating data across multiple frames. iMet-4 sondes should not be affected.

There are no configuration file changes in this release, though a note has been added regarding the APRS changes.

Note: We are aware that new installations may display the following message on startup:

The WebSocket transport is not available, you must install a WebSocket server that is compatible with your async mode to enable it. See the documentation for details. (further occurrences of this error will be logged with level INFO)

This can be safely ignored. The web interface should still continue to work as usual. Eventually we will figure out how to suppress it...

The pre-built Docker Image is now the recommended way to setup radiosonde_auto_rx on a new station. Using Docker avoids issues with updates to dependencies, and allows for fixes relating to system packages to be easily pushed out to users.

Please report any problems encountered either on the mailing list, or by raising an issue on this repository.
