Apologies... was not asked what is an Si570 that I know as did they but which version is it... looks like the bag standard Si570 (abt £15 in UK).

I have an unmade KX3 in the shack (DXpedition stable mate to my other one) and I will hi-res photo the boards and blog the build.

I still wish Elecraft would release the circuit diagram as the risk of chnese knock off has to have passed by now...
