Thanks guys for the warm welcome. Would this WU 2-B be a good candidate for
printing RTTY off the air? Or would I be better off with finding something
that prints on a more traditional role of paper. If that's the case, I
don't really have a lot of room to keep anything extra and would like the
2-B to find a good home with someone else. (it's free to anyone that wants
it. The family would rather see it go to someone that would enjoy it vs
scrapping it). I wasn't quite sure what it used for paper when I quickly
looked it over.

73,
James KB2FCV
