Hi All, I am enjoying RTTY with old Kleinschmidt's machines. I posted some article of the TT-76/GGC to my home page. Article was written in Japanese but there are several photos with it. And also you can find the LINK for TT-4C/TG and TT-297A/UG in Top Page. I hope you visit to my HP to see those machines. 73's Taddy, JK1VXE
