Annex III – Connection for the Elecraft K3
In the K3 we use the ACC connector. The pins used are as follows:
Pin1
FSK IN (pullup a +5V)
Pin5
Gnd
Pin7
TX Inhibit
Pin10 Key Out
The connection that needs to be made between the interlock’s DB9 and the ACC is
as follows:
Remember that you need to insert a resistor (10K ohm for example) between pins
1 and 7 of the ACC connector. Additionally, you will need to enter the SETUP menu
and change the CONFIG:TX INH to HI so that pin 7 works as TX Inhibit
