I have been using the ATMEGARFA1 in several designs. However, when I connect the analog reference pin (ARAF) to 3.3V, the radio stops receiving. Transmit still works fine, but receive returns nothing.

as well as in my own design (which, in fairness, are based on that board).
Has anyone had this problem? Or know what a solution might be?
