[Elecraft] Using external sound card for digital modes

[David Ahrendts]

My friend, I had the same type of problem in bringing the KX3 up to speed for digital. The rig would begin wildly scanning when connected to an Mic sound card. My solution was to use my old Signalink sound card instead with a home brew cable. Does a very nice job. In trouble shooting the iMic (which I never got to work), someone mentioned checking the mini-plug type. Remember the KX3 microphone plug is a tip-ring-sleeve plug (TRS). Presumably a mono or stereo plug would cause unexpected things to happen.
My two cents for you.
