The FCC said " 'ROS' is viewed as 'spread spectrum,' and the creator of the system describes it as that. We assume that he knows what he created."
This is unequivocal. However, the FCC also says "The Commission does not determine if a particular mode 'truly' represents spread spectrum as it is defined in the rules. The licensee of the station transmitting the emission is responsible for determining that the operation of the station complies with the rules." Thus if someone were to convince the FCC that ROS is in fact not spread spectrum, then ROS could be used on HF by US operators. However the source of this proof would have to come from someone other than the ROS developer, who now has no credibility with the FCC whatsoever. 73, Dave, AA6YQ -----Original Message----- From: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com]on Behalf Of Rik van Riel Sent: Thursday, March 04, 2010 5:54 PM To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] FCC on "ROS" post on ARRL website!

The FCC just says that: 1) spread spectrum is not allowed on HF, and 2) The Commission does not determine if a particular mode 'truly' represents spread spectrum, and 3) The licensee of the station transmitting the emission is responsible for determining that the operation of the station complies with the rules. Once Jose publishes a full specification for ROS (one that is complete enough to create an interoperable alternative implementation), US hams will be able to make the technical determination that the FCC requires us to make. Until then, there is no way to be sure whether or not ROS is legal to use in the US. We simply do not have enough info to make the determination. I expect that cautious US hams will avoid ROS until there is certainty that ROS is in fact legal. -- All rights reversed.
