Elecraft T1 ATU in FT 817: Done.

As described in http://www.ngunn.net/cyberworld/hamradio/t1/ I have successfully integrated a T1 tuner into my FT 817. My tuner was sensitive to noise on the 9V rail - using the 12V rail from the data port and some blocking capacitors I finally got the tuner working.
