K3 and NUE-PSK

[Paul Ryan-6]

Hello All,

My NUE-PSK Digital Modem arrived today and I'm getting ready to wire it to the
K3.  I searched the archives but didn't see any posts on anyone successfully
wiring it up and what choices they made.  If someone has, I'd like to hear
your thoughts and experiences.  

Lacking any other data from the group, I'm inclined to wire the modem's AUDIO
OUT line to the KIO3's MIC-MONO jack and set MAIN:MIC SEL to RP, Low Z and
Bias OFF.    Then wire the AUDIO IN to the KIO3's PHONES jack with a stereo
plug but only connect to the tip for mono audio.  The PTT will go to the PTT
IN on the lower panel.  Select DATA-A mode for operation.

If anyone sees a problem, or knows a better way, please let me know.

Thanks and 73,
Paul, N0KIA

I suggest using the LINE IN and LINE OUT jacks on the K3.  The NUE-PSK
modem has no isolation transformers in the audio, and if you are using a
wall wart or other non-battery supply, you may get ground loop-related
noise...
