Continuing my interest in Navy communication gear, I have started a web page listing info on Navy TTY equipment. http://www.virhistory.com/ham/navy-tty.htm This is a "work in progress" so any comments, additions, pointers to photos, etc. is very welcome. For instance, what's the diff between AN/UGC-5 and AN/UGC-6 ? Happy New Year to all, Nick KD4CPL
