Yes, I was taking power from the mic jack on the rig. Used about a 1k
resistor as a current limiter.
I can give you a text description of the circuit when I get home this
evening. That caused an interesting problem. The k2 is not exactly
kenwood equivalent wiring.
With the ts2000, dc was on pin 5 I think. However, on the k2 it was on pin
6. So, I installed a toggle switch for that as well.
