My Old K3 is in for repair and upgrade. I'm replacing the K3io board
with the new "B" model. Apparently from what i read i will no longer
need the line in and line out cables. Am i reading that correctly? It
will then use a regular USB cable from the radio as a replacement as i
understand it. Is there a new firmware release that will address this
or is the latest that has been published going to work? I'm wondering
what different settings will have to be changed. I use it mainly on CW
& FT8 modes.
