Talk about dredging up some history ... from 2009??!!
I've read through this thread and a few others and have not found upon any
solid answers that was posed by the OP.
My K3 (S/N: 9013, Assembled: 05/10/15) started having the very faint key
clicks late yesterday afternoon. As noted in the thread

I happen to remember which relay it was, I'll post it here. 73

I've followed this thread concerning a QSK clicking noise through all
comments, as well as other similar threads on the list, but it doesn't
appear as if anyone ever came to a firm conclusion as to origin of this
clicking noise. As others have stated, I can hear a very faint mechanical

I am probably am just hearing "things", but for some time I have heard what
sounds like a relay switch, just once, in my K3, #1292, while it is powered
off. Is there anything that would be still powered and "busy" while the K3
is supposedly "OFF" that could be doing this? I have no other equipmen

Hi,
I just had a listen to my K3 when keying. I cannot hear the tick at all in
my left ear, but can hear it in my right ear providing I turn my ear towards
the top of the K3. If I put my mechanical wrist watch (Tudor Submariner) to
my ear it is louder than the tick from the K3.

I have heard this relay noise since I put together my K3 kit s/n 1484 in
August 2008. I always use full QSK, and then it's easy to hear the clicks if
the room is silent.
I was little surprised in the beginning, as I had read that the T/R
switching should be all electronic. I didn't think no more a
ause I can hear the
mechanical clank fairly well.

It may be the delta in supply voltage on keydown slightly stimulating
one or more relay coils. The DC shift could move the contacts a tiny
bit. Or it might be an extremely small timing window, associated with
T/R switching, that puts a little glitch on a relay control line.
Either way it's nowh

This could be a new generation of firmware update technology --
adding an actual relay :-)

My K3 makes a very quiet relay like keying noise as well. Been
meaning to chase it down, but haven't had the time. There was once a
suggestion that it could be a protection circuit due to high SWR, but
there's no reason why that should be happening. I haven't tried
disconnecting the s
There's a relay that switches with mode change, CW/Data to SSB/AM.

Steve,
No relay for either keying or T/R switching - it is all electronic.

Is there a mechanical relay that follows keying? I've had my K3 for nearly a
year and didn't notice any relay noise until lately. I know the antenna TR
is done by pin diodes but I can now hear the faint click of a small relay
that wasn't there before. I'm using ver. 2.8

Thanks for the replies, ok, I'll get used to it.

That sounds similar K2 bandpass filter switching relay, noisier that I
would have thought but acceptable. The relays in my Dunestar 600 are
audible but quieter than the K2.

One thing I've noticed is the relay noise (physical, not RF) when switching

moving up or down through them consecutively (quieter).
