    it's sitting on my desk and I am ready to start using it, but I fall short of understanding some basic connectivity requirements (I have never had an external amplifier before in my life). I need to connect a "PTT Cable" from my radio to the Palstar PTT connector. Now, it was easy to find the one on the Palstar, but I am not sure what, of the many, ports I should use on my FTDX-3000. I have an idea but I don't want to do the wrong thing here

    Can someone help me?

    You use the DB-15 LINEAR jack on the FTDX-3000: Pins 2 and 3 are TX GND and GND, and you use only those two pins for interfacing with the LA-1K's RCA phono jack.
