K3S/FT8/Mac mini Problems

[Richard-6]

I posted a description of the problems I’m having but the reflector killed it because it was too long. Here’s the first part:

-----------------

Mac mini running Sierra 10.12
New K3S
Using USB cable only
WSJT-X version 1.8.0
Primarily FT8 for the moment

Major Problem #1:
Communication between the software and the K3S is unstable and unreliable. For example —
  When the software goes into Transmit right on the button, the K3S power comes on 2 to 3 full seconds later. When the software comes out of Transmit right on the button, the K3S keeps transmitting for 2 to 3 seconds.

Sometimes the K3S NEVER stops transmitting.

Sometimes the software goes into Transmit, but the K3S doesn’t transmit at all.

Fun, huh?

If you think you might have some answers, please e-mail me at [hidden email] and I’ll send you the whole thing.

Thanks.

Cheers!

Sounds as though RF is getting into the computer.

I had the issue and added ferrite cores to several cables. Including the one between the radio and computer. Some improvement noted.   Replaced the USB cable with a good quality shielded cable. Problem solved even at near legal limit.
