[Elecraft] Anyone with interfacing KPA1500/K3/P3 and steppIR SDA2000

[John Kountz]

The P26 cable works fine to connect a P3 with a K3.  The S14 "Y" is comprised of two female connectors and one male and can be used to connect the P3 to the K3 but not the SteppIR SDA2000 antenna controller.  Given the requirement for these three devices be interconnected is there anyone out there who has surmounted this problem?
