Hi all,
I hope you can help.
I have a Clas Ohlson WH1080 weather station, it works on the 868M frequency, a couple of weeks ago i bought one of those generic rR820T SDR dongles.
I fear the dongle now may be a little deaf as this was working a few weeks back on a windows build of rtl_433, ( I could see my watchman oil sensor, drayton thermostat and also the weather station) I also tuned into the local radio station. Roll on a few weeks later with the dongle floating around in my bag ....(static ????) I decided to start the preparation for a weatherPi build. I thought I would get it working on my laptop running ubunbtu/mint first... fire up rtl_433 and sadly didnt pick up anything :( . Dongle back in the windows machine works on FM stations but not picking up any of the sensors as before (tbh canot remember if i upgraded rtl_433 version), dongle back in ubuntu and again the dongle is not dead still picks up FM radio and sees a a pulse every 48 seconds , which ive correlated with my base receiver.
ive loaded up GQRC and tuned to 868.2 and can see the signal every 48 seconds.
Do i have a busted dongle , could the aerial be damaged?
help please !! this is driving me nuts.
Thanks Tanya

Hi Ben,
you mean rtl_433 -r g001_868.2M_1000k.cu8 -A ?
when i was searching it was rtl_433 -f 868.2M -vvv -S unknown
but for the most part ive been using variations of
rtl_433 -f 868.2M

Hi Benjamin,
Just tried again, and timed once more with my weather receiver (there's an icon when the base receives an update)
a bit more promising.

I think it is just unsupported.

The modulation is OOK not FSK as you have.
We have this issue that is tracking this.
https://github.com/merbanan/rtl_433/issues/1330
So keep track of updates in this ticket.
