[Elecraft] KRC2 Band Decoder question

[AB2E Darrell]

Hi all,
I picked up a KRC2 Band Decoder.
Are there any issues using this with a K3?
Does the stock DB9 cable to the rig need to be rewired for the K3?
I want to hook it up for FD with a bandpass filter set.
If anyone is using it with a K3 please email offlist.

Thanks and 73,
Darrell AB2E
