[Elecraft] K3: How to setup K3 with Signalink-USB ?

[Don Wilhelm]

Bob,

Do you have the K3 set to activate either keying or PTT from the DTR or 
RTS lines (CONFIG: PTT-KEY menu set to something other than OFF-OFF)?  
If so, the K3 will go into transmit (not TX TEST) when the computer 
boots up and tests the RS-232 signal lines.

What the manual says is that *if* you are in that menu entry, then an 
active DTR or RTS line will result in the K3 going into TX TEST. 
Normally, you will not have that menu item open, and the K3 will go into 
real transmit.

To avoid this situation, you can boot the computer before powering the K3,
or switch the K3 to a dummy load while the computer is booting
or manually put the K3 in TX TEST while the computer boots
or disconnect the RS-232 connection.
