Ok Many  thanks'  for the&n= bsp;=20 reply's
 
From that .... next is :-
 
From the  data, I assume th= at =20 100  Hz is the  common  limiting factor for a  nar= row =20 band  data transmission  that  could be used by all&nbs= p; who=20 'wanted'  to  use it  ?..(noted on the  cw keying&= nbsp;=20 speed  ~ BW)
 
So if a  value of  100 Hz= is =20 specified, what  is the  'presumed'  roll-off of the po= wer in the=20 said bands ?, assuming that  the  original  concep= t was=20 based on CW operation , which by  definition 'has to' generate=20 sidebands , there must be an assumed  tolerance ?
 
Q  would the deployment  of= a =20 system that  could   defined as   125 hz bandwidth=  =20 ie 100 Hz with   +/-  12.5 Hz  overspill , cause&n= bsp;=20 a  technical  breach  of the  regulations  or=  =20 be  viewed as  occupying  the  'allocated' bandwid= th =20 for a  telegraphy transmission ? ,
 
Taking that  spectral measuremen= ts in=20 the  10  Hz  region are  perhaps  starting=20 to  test  even the  best equipment, the  area=   is=20 perhaps a  little  empiric ?
 
I use the  word  telegraphy= , purposely to=20 view/observe the  situation interims of the  licence = =20 conditions and not on the  basis  of  'mode' which= =20 like  Liverpool  and Everton have there  own sub cultur= es=20  but are still  football  teams ..
 
Thanks
