    But now what can I use to get it onto a board without drawing it out by hand??

    What is it? I can't make out the image you attached.

    Life's Too Short For Making One-Off PCBs

    A simple PSK31 interface like this lends itself very well to Manhattan construction.

    I can't read the drawing he posted...my eyes are not that good. Does he use an optoisolator by any chance? How is he isolating the rig from the soundcard?

    Manhattan building techniques would definitely cover this one.

    As far as I can make-out it's quite standard; an optocoupler, a couple of transformers and a trimpot. Perhaps a couple of resistors.

    OOPS

    I tried to made it larger BUT it seems that photobucket automatically changes it from a bitmap to a jprg and it looses quality.

    It uses an isolator with connections for RTS & DTR, along with pots for the RX and TX lines so I dont have to go back and forth resetting my soundcard etc.

    took some work but its MUCH bigger now :D

    the receive and transmit section are slightly modified from the same source. the keyer circuit is slightly modified (added 2nd keyer line) from
    a different schematic.

    You could down load one of the many PCB cad programs, learn how to use it, buy a laser printer if you don't already have one and learn how to make a toner transfer board.

    But for something this simple, building a couple on perf-boards would likely be quicker and less expensive!
