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

No, mine persists with mike unplugged. The only thing that kills it is unplugging the "TTL" plug on the front of the Remote Rig.

It goes away as soon as I disconnect my mic from the mini! No matter if using the front socket or the 3,5 mm socket. As soon as a mic is plugged in and the mini is turned off there's ticking. Must be something in the mini itself (or the mini in conjunction the the RR controller) as I did not have it when I still had the old PCBs inside (before the swap against the new ones with a display readable when tilted).
