REPLY:

When you say above 250HJ1B, I believe the "1" should be a "2", correct? CW
is "A1A". 

In part 97.307 (f) (14) why does the FCC make a distinction between a "data"
mode and a "RTTY" mode? Data modes are allowed 2.8 kHz but RTTY modes are
allowed only 60 Hz. 

I suspect the distinction above was accidental, but until it is corrected,
it is in effect.
