This codes works pretty well for upp to 50 meter if the antenna of the recviver is not moving and it uses True mode and SERIN/SEROUT and it doesīt work with Inverted mode????

If iīm in the range of 30 meters it doesīt miss any numbers or loos the value in the variable "Check".

Why does the the Serin2 and Serout2 thats used in the BS2 sampel for these 2 modules donīt work at all.

Are you living in a city area?
No.

If not, it is possible that there is another transmitter within 500m?
I donīt think so but you never know.

Do you have an oscilloscope?
Yes at work, but not here at home.

Iīm going to test later whit a wire direkt to the PIC.

Maybe this modules doesīt work better and this?

What is the diffrens for the LINX modules to be driven by Inverted mode or True mode?
inverted mode (as in the BS2 from Parallax sampel) shold be the best for these modules, or?
