Ok Walter
 
Well that is a good  question= ! ...=20
 
Its a  narrow  band = data =20 mode that  uses a combination of   multi  tones= and =20 amplitude modulation .. the  tones relay the  data = and=20 the  amplitude modulation  provides the  syn-pulse ..= so =20 every character   has its ''own sync pulse''  so the&= nbsp;=20 system has no  'lock up or  sync time'' 
 
I am using  FLDIGI  as th= e  tx=20 software .........  you  need to be very  close on fr= equency to=20 decode
 
Tnx - G ..
