[Elecraft] K3 and Signallink

[Ross]

I have just checked my K3 again after a couple of months not using it, and I have a problem with the Signallink.
Yes I know all the comments about it, but I want to get it going before I try to instal the Microham keyer.
On transmit the Signallink is working perfectly, it produces the output and keys the k3, but I cannot get any audio, the line in and lineout plugs are in the correct positions on the k3.
So can someone please guide me as to what could be wrong, would it be the settings on the k3 or something else.
(I have checked 2 digital programs with the same result, transmit is ok, but no audio coming through.)

Thanks
Ross
