[Elecraft] K3 port sharing and FT-8

[Mark Musick]

As a comment to both Allan's and Don's replies, Win4K3Suite uses Com0Com for its virtual ports. I use Win4K3Suite and like Allan I have N1MM, MMTTY and I have WSJT-X all connected at the same time and have had no issues.

Wes,

You are asking about the limitations of the computer software applications, particularly those providing virtual ports.  So I don't think a different radio will change things.

You might try Com0Com - have not used it, but I know it is different than LP-Bridge.

I think your problem is with LP-Bridge, which buffers K2 information to take the load off the K3 serial communication.

Yes, WSJT-X wants to have total control of the radio.
