That works with Thinkpads of the T2x and T4x vintage. I suspect that it
works with many others. I've been doing this for years to eliminate
hum/buzz issues that result from leakage current from the AC power system.

This occurs when CMP and MIC settings are very high, while TX Gate is
set too low.
Maybe an increase in TX Gate level and reducing MIC and/or CMP will cure
the other problem with the transverter.

Hi all,
I did manage it now by reducing mic and comp so its fine now.
All settings was to much with 25 - now it is 10/15 with the HEIL.
Thanks for fast answer - a good reflector !
I like it !;-)

If you are using any kind of rig control with your computer (and
therefore have a shield connection between the K3 and the computer, such
as via an RS-232 cable), make sure the chassis of your K3 is securely
bonded to the chassis of the computer with a very short length of large
gauge wire or
Try reducing your compression setting. I get a noise at 25 also.

It is not a fan, it is RF or other noise getting back into the mic
circuit. I had the same problem. Check the two mods on the Elecraft K3

Hi all,
I use at my K3 a HEIL PRO SET ELITE "IC", I had this as I use it at my
old ICOM IC-275H as well.
Now I recognised that I have a small noise on modulation like a fan that
gives me some power output when I just push PTT.
OK I have in my shack 2 additional fans for cooling the PA so I switch
