[Elecraft] KXPA100 connections

[Rick Dettinger]

Thanks Don,

I did read the instructions wrong.  I was distracted by the idea that the KXPA100 would be "plug and play" with the companion KX3 transceiver.  Since it is unlikely that I will be able to find a cable with an RCA plug on one end, and a 2.5 mm stereo plg on the other, without tip wire, it looks like a custom job.
I don't know if I would have a use for the features of the KXCABLE, since I don't have a high power amp, a KXAT100 or a computer in my shack. 
I do appreciate the fact that it would be necessary to modify connection cables for unknown brand X transceivers.
