[Elecraft] Interface cable question

[Terry Brown]

I just purchased a miniHFPA2 amplifier to use with my KX2 when I am in the
field and don't want to lug around my KXPA100.  I need to build/buy an
interface cable that will go from the ACC jack on the KX2 to the RCA PTT
jack on the miniHFPA2 amp.  Can anyone tell me where to get an interface
cable or if there is any other interfacing need besides connecting the four
conductor plug's sleeve to the ground of the RCA plug and ring 2, key out to
the center conductor?

 

Thanks,
