[GreenKeys] Fw: Rewiring a Model 19 ASR for RTTY

[Lee Mushel]

Well, I seem to remember being told a long time ago that if you "can't hear 
'em, you can't work 'em" so the first problem is being able to receive.  And 
Eric's board will get you past that.   Now, if you google Triad N 48 X you 
will get a few pages of references.   I thought everyone did that.   I know 
that people expect me to!

I also suggest that you watch eBay for book items like "RTTY from A to Z" 
and some others.

regards,

Lee   K9WRU
