I'm using a BXB6 receiver (witch looks very similar to the one shown in your images) and an Auriol H13726A (07/2013)

I had no success using "Receiver" sketchs included in VirtualWire and RCSwitch library.

The Arduino Uno and BXB6 can receive raw noise+data with a very simple sketch.
Is a simplified sketch available to just test the receiver alone?

Hi Dino, welcome

If I'm not wrong, none of the example sketches included in those libraries will be able to receive any data from an Auriol weather station.
Take a look at our AuriolDuino code, certainly you will be more successful... or help us in the development, getting an AuriolDuino kit.
