[AMRadio] W2JAV RTTY TU for use with my model 15 TTY

[Rob Atkinson]

I have a copy of The New RTTY Handbook I found in cleaning the
basement, 1962 ed. 1971 printing, softcover Cowan Pub Co. (CQ
Magazine) and I sent an email to the Greenkeys moderator asking him to
post it as a giveaway and never heard back from him.  If any vintage
RTTY ham is on this list and wants it let me know.   I think the
author of it is Kretzman or something like that and it has tube
circuit schematics in it.
