Rich,
Do you have audio out of the KX2 on the headphone jack? If so, the
other thing to consider is the adapter to the TRRS plug and the audio
levels for Microphone or Line in your computer. Make sure you computer
does not have the mic disabled. If windows, check the soundcard
settings - there is something similar with a Mac, but I am not a Mac user.
Recent upgrades to Windows do mute the microphone or line input.

I am trying to connect a KX2 (which has a standard headphone output and
microphone input on separate 3.5mm jacks) to a laptop that has an integrated (4
pin TRRS) microphone input and sound output. I have the adapter than converts
the 4-pin 3.5 mm jack to two separate jacks, for a microphone input (to the
laptop) and sound out (from the laptop). I connected those jacks to the
corresponding jacks on the KX2, using stereo cables. This is the exact
configuration as shown in Frank Cady’s KX2 book.
On transmit, everything works fine. I can key the radio from N1MM, send CW (via
KY commands), and send digital data (e.g., FT8) to the radio and the radio
transmits everything fine. All levels can be adjusted to perfection.
On receive, I’ve got nada. I can’t see any audio coming from the radio into the
laptop. If I disconnect the external input, I can actually decode digital data
with audio from the radio’s speaker, through the air, to the laptop’s internal
microphone. Now, I can deal with the differences in levels, if necessary, but
I’m not getting ANY audio from the radio to the laptop via the cabling. What am
I missing? I’m hoping to make this work without lots of little adapter boxes,
USB hubs, external codecs, etc. for very-portable operation.
