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:

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.
