With the W6DHW board and a CMOS SI570, insert the signal between JP1 pin 2 & 4 
for /4 operation and leave the JP2 crystal jumpers off.

I'm trying to interface the W6DHW board to my RXTX 6.2 kit and will try to use 
the PE1NNZ 
interface with the DB25 to control the "rig"

As I understand it, I have to connect three points of the Si570 board to 80 / 
40 selection 
"jumper" section of the RXTX board. (JP2) Is this correct? 

Do I have to disable the crystals on the RX TX ? I think not if I want to Xmit 
eh ?

I have the CMOS Si570... and also have the Xtall interface.

Any thoughts which would be the better route to go ?

Any advice is appreciated.
