[Elecraft] python k3 interface

[Mike Markowski]

Happy 2018, fellow Elecrafters!

This note shares nothing earth shattering, but something I find much 
more useful than expected.  Using python, a super simple programming 
language, I just wrote a small k3 library of commands do simple things 
like retrieve or set frequency, keyer speed, enter/leave no-Tx mode, and 
so on.  Maybe an hour or two of programming.  As you need more commands 
you simply tack on more to your code.  A sample run - whose source code 
any interested are welcome to - with comments is below.  But programmers 
can easily write their own in short order.  Wayne (et al.?) have made it 
a snap.
