You can reduce the LIN OUT level via the Config menu in the radio.
Normal is 010. I would back that value down.
I use Windows 10 thus I have full control of all levels via the
computer. Also I use the USB connection between the radio and computer
and do not need a Signalink.
I can't say I agree that RF Gain should always be at maximum, nor do I
agree that AGC should be OFF. I know that information in the WSJT-X
Help file indicated to turn AGC off. I know is I've been operating
my K3S for 3 years now, I use the RF Gain as needed to set the receiver
for optimum performance based on no signal band noise. And I run the
AGC on Fast with a RX BW of 2.7kHz and don't experience any issues from
strong stations. I think the key is setting the RF Gain and ATTN to
values to allow the no signal band noise to be about 10 dB above the
noise floor of the receiver.

The Elecraft K3s manual states over and over that the RF gain should always be
wide open. I had been running it at about 12 o'clock on FT8 for some time
before this was brought to my attention. I supposed that 100% RF gain could
possibly show me weak stations I’d not seen before, so I’m trying it.
In order to keep the Audio Input to WSJT FT8 at a reasonable level (nominally
40dB: noise only) with the K3s RF gain wide open I have to run the SignaLink’s
RX way down near full CCW. Very touchy and hard to adjust. SignaLink’s JP2
jumper is NOT connected. I do NOT use AGC, nor do I wish to.
Oh, this is a Mac so the USB Audio Codec input has no level adjustment.
Any suggestions as to what I might do to get SignaLink’s RX back to about 12
o’clock where it used to be?
