929.6125 Mhz accuweather forecaster #2383

Closed Harrball76 closed 5 months ago

Harrball76 commented 1 year ago

has anyone looked into decoding the accuweather radio signal? I have a couple 7 day forecaster that receives data on 929.6125 Mhz. even though accuweather states they disconnected the service in 2019 it is still working.

the model i have is a Bushnell Weather FX5 950015C. the weather is updated about ever 15 mins

Interesting. That's just the indoor unit, no outdoor sensor, right? What ist broadcasting the 929.6125 MHz signal? Can you capture a sample? https://triq.org/rtl_433/ANALYZE.html

here are the files on that bandwith

Good clean signals. But very much payload data, I don't think there is an easy way to just guess what those bits encode...

This is the device that is receiving the signal. I am still going to work on this. If anyone else has any ideas please let me know

Great to hear, happy hacking! You might need to decode the payload by hand or with URH. The demod in rtl_433 struggles with GFSK.

merbanan commented 1 year ago

The signal is clipping so the demodulator fails badly on these signals.

zuckschwerdt commented 1 year ago

Not by much, but yes, that probably needs adjustment (distance, antenna, or fixed gain).

This doesn't have actionable content. Please retest and re-engage with up-to-date git master.

Here is another article about this service

It's compared to POCSAG and it might be better to write a dedicated receiver for it. Also there is mention of it shutting down perhaps?

This doesn't seem to fit and has no activity.
