= 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/

 

 TX / RX  set :::   502.000 KHz 

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

 

= Many thanks'  to all
