I have down loaded the Orion manual and have browsed through it
looking for information on RTTY. I notice that is is stated that AFSK
is used. On the MODE menu I see FSK as one of the options. I wonder
if the AFSK is generated internally, are there options for the shift
and the tones used, or if it's necessary to use the Audio IN on the
AUX I/O Connections Figure 2-25 page 2-13..., I don't see any mention
of a Mark-Space connetction on the AUX I/O connections.
These is a short discussion of External Modems.. 2.6 Using External
Modems, page 2-13
Does anyone have any idea about this ??
