= Test of ROS 100= Mf Mode tonight

= Thanks to all who supplied information of there respective 500 KHz=20 permitted transmi= ssion=20 bandwidth.

= After some negotiatio= n , Jose has coded a 100 Hz of his RO= S data = ; software , this now gives the system an =20 =91MF=92 m= ode=20 operating inside the 100 Hz licence conditions

= The 7 baud mode is a<= SPAN style=3D"mso-spacerun: yes"> live keyboard mode , being fast enough to maintain a reasonable qso&= nbsp; speed , with selectable afc range

= The 1 baud mode is perhaps more of =20 a beacon mode ,= but offers enhanced performance and is perhaps a contender to the conventional QRS/S&nbs= p; modes

= Transmission of=20 the mode requires the = traditional a= udio to =20 rf translation= , but as it=92s=20 a single carrier system , non linear amplification=20 systems may be deployed.

= This is the first custom built data mode = resulting fro= m the interest and participation of monitoring and active stations , <= SPAN style=3D"mso-spacerun: yes"> transmission system experiment undertaken on 500Khz facilitated by the= OFCOM issued = UK experimental research &= nbsp;permit

= The software may be freely downloaded from &nb= sp;http://rosmodem.wordpress.com/

Carrier centre frequency= =20 will be 503.000 KHz +/= - =20 49 Hz
