I've been wandering on the AA5AU RTTY pages in search of
Don's email address.
After my exchange with Chen, I had a question about the
RTTY Intro page on Don's site. It is noted that high tones
are 2125Hz and 2295Hz (170 Hz split), Mark and Space
respectively. While nothing is specifically mentioned at
that point, the Mark and Space designations given are only
applicable for LSB. On USB I believe the designations should
be reversed, since 2125 Hz would be the LOWER RF frequency.
Am I right or merely confused?
Thanks ES 73,
de Phil - N8PS
