[Elecraft] K3 PK-232 FSK RTTY Setup

[Ed Gray W0SD]

Don,
http://pinouts.ws/db15-vga-pinout.html  shows the pin out and I don't 
see any pins connected together unless the grounds are common.  I did 
check  a lot of pins with the DMM but I did not find any in common but I 
did not check each and everyone.  I will do that.  Anyway your point is 
well taken as running 3 wires as PTT is also required makes more sense 
than having all the extra although the molded plug is nice for reliability.
