Alex, There is no direct relationship between the KAF2 and the Pre-amp / Attenuator functions - the control board microprocessor does control most everything in the K2, so that would be the only thing common - control is through the AUXBUS signal, but if that signal line had a problem, there are a lot of other things that would not work too (things such as band changes).
Check to see if the relays for the preamp (K17) and Attenuator (K16) are being changed - if they operate properly, at least the attenuator should work because it has no active components, only resistors and the relay. 73, Don W3FPR > -----Original Message----- > > Hi! > I have a problem after instalation KAF2 on Control > Board.
