Radiosonde Feature Plugin loses connection with SondeHub

[GabrielSampol]

I am testing the Radiosonde Feature Plugin in the latest version of SDRangel (Qt 5.15.2 65 bits) on Windows 11 and using an RTL V4 dongle.

It works nicely, except that it seems to lose the connection with SondeHub after running for a while.

The steps to recreate the issue es:

• Radiosonde decoding starts and frames are beeing received and shown by the plugin and track on the maps.
• My callsign appears OK in SondeHub as receiver of the radiosonde
• After a short while my callsign dissapears in SondeHub as if I was not sending data, but frames are being received and processed by the plugin.
• If I close SDRangel and start it again, SondeHub list me again as receiver, but also again stops doing it after a short time.

Is this a known issue? If you want me to make some additional test just let me know.
