Hi John,
This happens when the shift character gets missed somewhere along the
line. In MMTTY if you right click on the alpha characters, they will convert
to numbers, and vice versa. Manually you can figure it out by going to the
QWERTY line on the keyboard and going NW from the letter to the number.
That's how to explain the TOO you so often see - it's 599! In your example
QWI is 128.
Usually this happens just because the shift character (non-printing) gets
scrambled like any other character, but I've seen some stations which had RF
feedback or some other problem and all their serial numbers are
consistently sent as characters. They don't print that way on the
transmitting
station's screen, so they don't know what is going on.
Welcome to RTTY contesting. Hope to work you many times. I see we have
worked a number of times on CW.

I just operated my second WPX RTTY contest and third RTTY contest ever and
I
had a great time on 20m. On several occasions my MTTY decoder copied the
serial numbers as letters. I was able to copy everything else fine during
these QSO's. Is there a letter - number conversation chart? Also after
reading W0YK's contest summary on using multiple configurations and
decoders
, I am wondering if there is a site that would show how to set this up and
which comercial decoder is the best. This is my first RTTY post and I
hope
that it makes it to the list!
