Re: [digitalradio] ROS experiments
Congratulation Jose for take your time for develope a new mode. If is Illegal I think is not, because is experimental and that is part of this hobby, so for other part the most other new digital mode start in experimental mode like ROS.

Re: [digitalradio] ROS experiments
I made the experiment over AWGN and ROS is 2 dBs better than OLIVIA 32/1000. But we are comparing two modes at differents character rate. As you know ROS is two times faster than OLIVIA 32/1000. You should compare ROS 16 with OLIVIA 8/1000. Then the different is about 5-6 dBs for the same character rate. De: Andy obrien Para: digitalradio Enviado: sáb,20 febrero, 2010 00:28 Asunto: [digitalradio] ROS experiments My "experiments" (many receptions and 2 transmissions) today with ROS 1 and ROS 16 shows that it is quite an effective mode. Congratulations Jose. Of particular interest to me were the several occasions where I decoded a signal that was not visible in the waterfall or audible to my ears. It will interesting to see if Tony K2MO gets a chance to put this through the Pathsim tests and compare it to Olivia. My "guess" is that it will be close to that of Olivia 1000/32 , perhaps within 2-3 dB. I should also point out that I think the software is well designed and layed out. Over the years we have had many modes come and go. I suspect that in 2-3 years time, ROS will still be used. Andy K3UK

Andy K3UK Andy, I'd be more than happy to run ROS through the path simulator if I could get the program running with Vista : ) Can't get past the run-time error. Tony -K2MO
[digitalradio] ROS experiments
My "experiments" (many receptions and 2 transmissions) today with ROS 1 and ROS 16 shows that it is quite an effective mode. Congratulations Jose. Of particular interest to me were the several occasions where I decoded a signal that was not visible in the waterfall or audible to my ears. It will interesting to see if Tony K2MO gets a chance to put this through the Pathsim tests and compare it to Olivia. My "guess" is that it will be close to that of Olivia 1000/32 , perhaps within 2-3 dB. I should also point out that I think the software is well designed and layed out. Over the years we have had many modes come and go. I suspect that in 2-3 years time, ROS will still be used. Andy K3UK
