> My NUE-PSK Digital Modem arrived today... > If anyone sees a problem, or knows a better way, please let me know. 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... 73, Lyle KK7P
