[Elecraft] KX3 and PTT

[Lance Collister, W7GJ]

Hi Jim,

This is also how I hope to do the PTT control on the KX3, since I will have the tip 
of the ACC2 jack set up for triggering the PTT from the RTS line of the computer.  I 
bought some plugs from DigiKey but am waiting to receive the KX3 first before 
building any cables.  Looking forward to receiving it soon so I can get started 
making it compatible with my 6m EME DXpedition station setup!   VY 73, Lance
