K3: no output on "line out"?

[Franki ON5ZO]

I am trying to get set up for RTTY with an MK2R+ and N1MMLogger / MMTTY.
It seems the line out is dead: I don't get a waterfall on the screen. When I
plug the cable from the other radio in the K3's slot on the MK2R+, I get a
signal. I tested the cable between rig and interface which seems OK.
So my conclusion is: nothing comes out of the LINE OUT. I looked through the
manual but only found the LIN OUT level parameter which I cranked up to the
max but that doesn't fix it.

Any ideas? Am I forgetting something?

Franki,

Check your connections.  Some of the microHAM K3 cables have
the Line In/Line Out (PC In/PC Out) plugs mislabeled.  The
3.5 mm plug with the 3.5 mm female jack (used for subreceiver
audio) should be connected to the K3 "Line Out" jack.

Are you assuming as I did that as you have the mic gain set, it should
be putting something out?  Once you go into data mode, the mic gain
becomes a line gain and is totally separate.  I still do not believe
this is made clear enough in the manual.  Of course, it could just be me :)

I was a bit too fast. I connected a set of PC speakers to the "line out" and
they let me hear everything. So it's not the line out circuit.
I was lead to "accuse" the K3 because the MK2R+ works fine on my other rig
in the SO2R setup. But now it seems it is the specific input on the microHAM
device so I will address them for help.

And yes: the labels on the microHAM cable seem indeed reversed for the K3,
but it doesn't solve my problem.

At least everything works fine in CW and keying my ACOM 1000 amp went all by
itself as well just by connecting the cable. I think the K3 is indeed a fine
rig - time will tell if it can make me forget the TS-850. If so I've got
another one to replace by a K3.
It makes a lot less noise in the headphones when RX on a dummy load, that's
my very first impression.
