[GreenKeys] CR LF, etc.

[William Wuttke]

A few years ago when I got my M19 up and running, I tried to copy the W1AW
ARRL bulletin. Sure enough, I had problems at the left margin. They were
sending only one CR. I contacted them and, even though they were using
fldigi and could fix it easily, they were unwilling to do anything about
it. I haven't checked lately, but I know they changed the transmitted mark
frequency since then. I think true RTTY is becoming a lost art. Computers
are taking over the world.
