I've tried at 100 kHz and 400 kHz -- the results are the same. And on connecting a logic analyzer to my Arduino I find it's running at 100 kHz and having no trouble. I'm sure it's a weird timing thing between commands, I just don't know where that is. The SX is much faster the Arduino, and that is somehow contributing to its success with this device.
FWIW, I connected loads of I2C devices to the SX28 without any problem at all. Things get tricky with devices like this that aren't officially documented. Still, I'd like to make it work and include it -- with credit to you, of course, Chad -- in my book, "Practical SX/B" that I'm writing for Parallax.
