ROS, developed by José Albert Nieto Ros, is a new digital mode. Using spread spectrum and 1 or 16 Baud signalling rates it is designed to cope with disturbances, low level signals, meteor scatter and moon bounce and claims that receiving signals down to -35 dB (!) with 1 Bd signalling rate and -30 dB (!) with 16 Bd are possible.
You can tell a ROS spot because they usually advertise the fact in the comments field and that in it self is fine. The part that gets me is that even though set frequencies have been suggested, kind of like channels the users of the mode seem hell bent on being very prolific spotters and even auto beacons just in case the rest of the world is missing their existence. If your into QRP and weak signal work you may find this new mode exciting. 73 John ZL1BYZ -----Original Message----- From: dx4win-boun...@mailman.qth.net [mailto:dx4win-boun...@mailman.qth.net] On Behalf Of Art - W6KY Sent: Sunday, 4 July 2010 15:43 To: DX4WIN Reflector Subject: [Dx4win] ROS, Left Behind OK, I got left behind..
