Is there anything else you changed from the examples given. I'm using the jaycar rf tx and rf rx given as examples in the pdf for virtualwire and though it compiles and seems to run nothing is coming through on the receiver. I think I've got the wiring right I used the default pins for vw_set_XXX_pin. I put an LED in for pin 13 and it goes on and off like the example code says it should but nothing on the receiver side. Bit at a loss on how to debug it.
