[Repeater-Builder] kenwood tk-840 with kct-19

[kh6bfd]

Looking for some help with the wiring diagram on the kct-19 pinout for the 
kenwood tk-840. I've seen some diagrams on the net. But, not sure how acurate 
they are. Want to hookup to a db-9 for plugging into my older laptop and 
running echolink. Anyone with good ideas, would love to hear from you.
