I had to make a DB15 cable since my K3 is side-by-side to the KAT500, so the Elecraft cable that I ordered is too short (the DB15-Y cable is the only one available and it is for a K3 on top of a KAT500).
However now my SB-220 Amplifier is no longer activated and does not 'fire up' when the K3 transmits. All was OK before I connected the cable that I made today, that is, the K3 and KAT500 did trip the linear amp's relay. The cable that I made today does connect the K3 and KAT500 properly, so that when I change bands on the K3 the KAT500 changes bands (and remembers the correct setting for each band so that no tuning is needed). Page 9 of the KAT500 manual shows the 10 Connector Pins to be used (leaving 5 pins unused), however I did not connect Pin #15 because the notation states "ALC (Not normally used...). This means that I have made a cable of 9 wires. It is my understanding that pin #10 is the Key LIne from the K3, which should trigger the relay in my SB220 amp (via the KAT500). There is an RCA-RCA cable from the K3's Key Out to the KAT500, and another RCA-RCA cable from the SB220 to the KAT500. This is the same configuration that I had prior to the new cable that I made today, and as I have said, the SB220 did fire up OK when the K3 transmitted. I took care in making and testing the cable, so I am sure of the continuity of each wire. There must be something that I have not done. How can I get my K3 to once again trigger the SB220 amp?
