IC02AT.11 This article taken from September issue of QST and may save someone a little grief. It's a simple procedure for resetting the CPU thet does'nt require opening the rig. 1)Turn there radio off 2)Press the FUNCTION button on the side of the radio and hold it on. 3)Turn the radio on. That's it. The CPU is reset to the rig defaults to (144 Mhz). Tnx Pat Maturo,N1DYI
