[Elecraft] Strange "Ticking" sound with K3/0 Mini to RemoteRig for remotely controlling K3.

[Brian F. Wruble]

Hi All:

The symptom I am describing persists despite changing routers, internet
systems, and cities.  In a QSO this morning, the other parties reported a
ticking sound on my transmitted signal --- faint but noticeable --- and I
could also hear it in XMIT Monitor.  I was operating my remote gear as a
test --- in the same room as the K3, and on the same LAN.

I have now set myself up 110 miles away, and the sound persists.  I am able
to work others, get good signal reports, but I can hear the tick tick tick,
about 2 per second.

In testing, I find the sound is there even if I power down the gear --- the
radio and the control end.  It persists if I remove 12VDC from the K3/0
mini.  Also if I remove the wifi module from the RemoteRig control box.

If I remove power from the RemoteRig, it goes away.  With power to the RR,
the ticking goes away if I unplug the "TTL" line from the K3/0 mini.
Unplugging the other lines makes no difference, though it becomes fainter
if I unplug "Aux/Mic." It persists if I remove the ethernet cable
connecting the RemoteRig to my router.  It persists if I unplug the USB
line from the RemoteRig to my PC.

This symptom appeared after a good period of time when everything worked.
And all functionality is still there --- just this maddening tick tick tick
--- like something from Edgar Allan Poe.

All ideas gratefully accepted.
