Has anyone constructed a cable to interface the K3 to the Tokyo Hy-Power HL-1.5KFX amplifier? I tried making one today, connecting K3 ACC connector pins 13, 3, 9, 14, and 12 to pins 1 thru 5, respectively, of the amplifier's Yaesu band data connector but the amp is not tracking band changes on the K3.
