[Elecraft] Interface K3 and transverter

[Mike Downs]

Alan,

I recently had the same problem. The following worked for me:

    ACC Pin 2 - Auxbus: connect to green wire - Pin 6 on DB-9
    ACC Pin 7 - K3 on signal: connect to red wire - Pin 8 on DB-9
    ACC Pin 10 - Keyout: connect to black wire - Pin 9 on DB-9
    ACC Pin 5 or 12 - Gnd: connect to bare wire - Pin 1 on DB-9

Also, you should put a pull up resistor between pin 10 and pin 7 on the ACC 
connector as pin 10 is an open collector output on Q7
> (MMBT3904), according to the KIO3 schematic. Finally, make sure TX INH is 
> is set to OFF.
