weathex sonde

[Joanvoo]

Hi, i try today decode the Weathex radiosonde but it was not possible.
Maybe a newer version?
bandwith = 60KHz frequency 403.700
a small piece of a another sonde is through it in the beginning (404.200)
a sample off the whole launch in audio wav format:

This was launched in Utrecht?

Looks like the Weathex 301D that was used at UAII 2022 in Lindenberg.
You can try this decoder
https://github.com/rs1729/RS/blob/test/uaii2022/uaii20220812_405400.c

gcc uaii20220812_405400.c -o wxr_uaii2022
./wxr_uaii2022 -i weathexsonde.wav

Don't know what the difference is between these two Weathex radiosondes. I believe they both are called WxR 301D, the signal is similar.

weathex/weathex301d.c can now also decode this variant (with PN9), but not automatically;
you need the additional option --pn9.
