[GreenKeys] XR2211 demodulator circuit boards?

[hwhall at compuserve.com]

Are there any printed circuit boards for building an XR2211 based RTTY demodulator?  Google shows me all kinds of articles from complex to over-simplified but doesn't lead me to any PCB artwork or vendors.
I'm thinking I might build a demod to run a Model 15 from a laptop running MMTTY. The program only outputs tones (no on-off output to key a loop directly) so a PLL demod should be fine since noise won't be an issue. Or should I look at something even smaller/simpler?
Thanks!WayneWB4OGM
