Thanks Rick, but that's not what I'm looking for. The K3YY unit is an
opto-isolated coupler for use when you already have an FSK keying signal and
want to couple it to your transceiver. 

What I'm looking for is a board that will take the two audio tones of 2125 and
2295 Hz from the line out of the computer and translate them into an FSK keying
signal. 

The K4DSP unit is what I need but apparently only the microprocessor chip is
available, nothing else. If anyone knows a source for this unit, either kit or
assembled, please let me know.
