Elecraft KX3 CAT's strange behaviour

[EA3GCV]

Hi Vit,

You should not have any problems. I'm also using VSPE 64 bits for sharing COM ports. Swislsog is always reading main VFO. Raise the value of the Control trasnceiver option "Time between two TX QRG queries in 1/10 seconds)" to a higher value. 1 is 100ms, 5 500ms and so on.

I have add similar problems when using the same virtual COM port in several programs at once (I guess some interaction). I suggest you to simplify and use OmniRig in all programs supporting it like Swisslog, JTDX, MixW.. For the VSPE side OmniRig counts as a single program and you "feed" 3 (in case you use Swisslog, JTDX and MixW at once). This will improve the CAT control and you will also have 3 more "slots" to share the virtual COm-port in other programs.
