Thank you.

Now i have recived the Parallax RF modules and write this test programs

It´s working very well whit in the rance of 50 - 60 meters whit the transmitter indoors and the reciver outdoors, but when i take the reciver also indoors in a house 50 - 60 meters away from the transmitter the counter on the reciver display starts to show wrong numbers sometimes but it´s still counting... but whit the reciver outdoors it does not miss a single number whit in 50 - 60 meters.

Any idé how i can to improve my code?

I´going to do some more tests to tomorrow, it´s soon time to sleep here in sweden...
