[Elecraft] KANT3 Replacement PC board

[Nr4c]

I suspect it’s a way to have more than 1 antenna connection without the KAT3.

This board is a bare (un populated) board that was made by someone to be a replacement for the stock KANT3 but it has some added switching and routing capabilities apparently.   It was a non Elecraft mod kit for the K3. I vaguely remember saying that I was interested in the board after someone mentioned the design on the Elecraft reflector.  I ended up with a board and the parts list. I have no idea how to implement same!

There are two antenna connections that go on the board along with the 20 pin connector that you remove off the original KANT3 board from your radio.

I must have bought it from someone on the Elecraft reflector, but I have no memory of any of it!   All I have is the PC board and a printed sheet with a parts list.  By board has "Copyright Arcom 2016  KANT3 REV 1.0" printed on it.

It looks like it was made to route extra antenna connections etc. but I have no information on what it does or how it is implemented into the K3. Can anyone point me towards a description  on this accessory?  I could find no mention of anything with a google search.
