Re: [Elecraft] KX3 ACC2 GPIO
I’ve thought the problem through further and have decided to use a simple mosfet switch in the connector shell to invert the TXInh logic sense and configure the KX3 for -TXInh instead of +TXInh. Hard switching the GPIO pin showed that to be a usable workaround. 73!

Steve Jobs was always about form over function. Icons had to have rounded corners, they were classier. Clearly, Transporter is a classier word than Transverter.

Re: [Elecraft] KX3 ACC2 GPIO
If you are using Mac OS X Mail, does it have the feature to add words to its spell checker? I just added a bunch of ham related terms to my editor because it was painting the screen red with all the "misspelled" words.
