[Elecraft] K3 & K3S Options Last Time Buy Update,, (12/02/2022

Well, I found the cause of the clicking (but not what is clicking).

I use two almost identical computers (DELL Inspiron desk tops).  One is 
for general Internet use, e-mail, etc.  the other is dedicated to ham 
radio sw.  The K3 is connected to the later one.  So I decided to try a 
different USB port (4 ports on back, 2 on front) and the clicking 
stopped.  I had disconnected a USB cable to do this.  When I reconnected 
it the clicking started back up.

That cable goes to my SDR-IQ receiver.  Apparently the two radios are 
interacting (maybe trying to connect to the same port?).  Anyway, simple 
solution is to run SDR-IQ on computer A and K3 on computer B.  Maybe I 
will explore this deeper at a later time.

This was not the start-up port testing that windows does.  This was 
non-stop clicking as long as K3 was connected (wether powered On or 
OFF).  Obvious it was computer generated as it stopped if computer 
shut-down or USB cable disconnected from K3.

curious that the clicking appeared to not interfere with K3 operation or 
running computer sw (like wsjt-x).

we can close this topic.
