[Elecraft] Adapter for use between iPhone headset and a KX2/KX3

[Phil Hystad]

Wayne,

I have yet to use voice (SSB) on my KX3 or KX2 having been so far CW only.  Are there any other
audio settings you have set other than those you mention below.  Do you recommend speech
compression set to max or was that just a test of audio quality check.  I will experiment but it
would be nice to know what starting points and boundaries make sense.

I still have all my iPhone headsets from my original iPhone 1 through my current 6s.  Actually,
still have all those iPhones too.  I may test each one to see how they work — now, I need to
find them all though.  Just ordered the Y-adapter cable from Amazon.

73, phil, K7PEH
