OK, no more excuses about the lack of serial ports for 45.45 baud, or the need to bit-bang your way to use FSK with modern sound card programs.
Doug K4DSP's article in the August 2011 QST is an updated version of his FSK Regenerator, and this time, he has a circuit board made for it. Just feed it AFSK signal from your sound card, and the little box will hard key your rig for Direct FSK.
Vote early, vote often (just kidding!) on the QST cover plaque if you are an RTTY nut.
Me? I use AFSK :-).
