There is a technical descrption at http://rosmodem.wordpress.com/. I doesn't
describe the start and stop tone sequences or completely describe the mapping
from the convolutional encoder to the 128 tones used for data. However, it's
more compete than some of the technical specifications on the ARRL web site.
Perhaps he can add more detail in the future.

Subject: [digitalradio] ROS Technical description for the FCC in the US
§97.309(a)(4) Technical Descriptions
This is a one-stop Web site for technical characteristics called for in FCC
rules § 97.309(a)(4), which reads:
(4) An amateur station transmitting a RTTY or data emission using a digital
code specified in this paragraph may use any technique whose technical
characteristics have been documented publicly, such as CLOVER, G-TOR, or
PacTOR, for the purpose of facilitating communications.
Documentation should be adequate to (a) recognize the technique or protocol
when observed on the air, (b) determine call signs of stations in communication
and read the content of the transmissions. Click on names of the techniques
already documented:
A technical description from you about ROS would help us in the US a lot. For
other technical descriptions go to
