I have test K0SM Arduino TinyFSK and it works very well without any timing
jitter. 2Tone will drive either of these directly via a COM port. In this
case serial port is not being used for bit diddling so no jitter.
If you must use FSK then one of these or a external box with a hardware UART
driving the FSK line is OK. But as noted many rigs have very wide FSK
transmit bandwidths. The only one I know that has a reasonable FSK bandwidth
is US made Elecraft K3.

Hi Peter,
Have you looked into TinyFSK?
http://www.frontiernet.net/~aflowers/tinyfsk/
I was looking into doing something similar as you with either a small form
factor PC, cheap laptop or some other device (which I still have to get).
Realizing that they would not have a serial port for FSK keying, I built an
interface that included the TinyFSK. It worked very well for me. I used it
with the N1MM logging software for some contesting as well.
