Do any of the relays operate (click), or is the problem only with the ones on the L-C board?
If none of them operate, check that the MCU is properly seated in its socket with no pins either sticking out to the side of the socket or bent under (you should remove the MCU to check for bent under pins). Check the soldering carefully - especially the MCU socket and the pins of P5 and J5. Pin 1 of P5 and J5 are the relay common connection, and if a solder connection is missed there, none of the relays on the L-C board will operate. 73, Don W3FPR > -----Original Message----- > > I am trying to install my newly built KAT2 into my newly built K2 ... > but have hit a wall.
