Hello Glenn! I found an old Thread from you in the Elecraft reflector. On the 28th of March 2009 you wrote that your K3 failed to load the FPF at the address x0040!!! I have the same problem now with my K3!!! Did you get it back to life? If yes, what´s the solution?? Hope to hear from you!!! 73s Alex OE6ASF, NH7VW, HB9TSF
