read 433Mhz weather sensor - Lacrosse TX7NU

GeorgeAn:
Hi,
I have a problem with the specific example with an OEM 433 sensor. The readings is correct but are not getting every time the device is transmiting the data. I think that it has to do with the sync period but is there a way to find theese tresholds.

Capture the signal into Audacity and then you can zoom in and measure the timings.
