I've had the cables all over the place. There seems to be only one cable whose placement has a significant effect on birdies. That's the long (10"/25cm)cable running from J84 at the bottom of the Auxiliary KSYN3 board to J85 on the KRX3 RF module. It should be dressed as shown in Figure 47 in the KRX3 manual. In some cases it helps to keep it away from the tiny toriods on the mixer board as well. Either run it across above the mixer board as shown or work it down under the mixer board so it loops up between the mixer board and the front panel shield to J85 on the KRX3 RF module.
