Some customers have found that the K3's "Line In" gain
(menu setting) is set to zero by default, thereby resulting
in no power output when transmitting. If up experience
this problem, then please consult your radio manual for
instructions on turning up this control.
Note that the K3 also has a menu setting for the "Line
Out" level, which can be turned up if needed to increase
the RX Audio going into the SignaLink
