[Elecraft] Mac utility with K3S Puts K3S in TX mode!

[Bill Conkling]

To all that replied.

A club member (my local Mac guy) suggested getting the latest FTDI driver, which I did from Elecraft website link.

I did change CONFIG/PTT settings to OFF-OFF.  All ok.  Tried starting Utility in SSB and CW mode with no errors.

Reset CONFIG/PTT to RTS-DTR, all still ok.  I think the driver did it.

Now, question?????

If I set the PTT-KEY to OFF-OFF, can n1mm still use those lines to handle PTT and Keying?  I assumed not, but……..

Thanks Guy(s)
