The  Opera  mode  ,  transmits  only  = a =20 single  on/off   carrier  , the  same as  = CW =20 or  QRS,   the  TX is a  serial  = data =20 stream.
 
Tx  can  be  via the  windows  based = software .,=20 with  com-port  CW   drive , Audio  as in  = say  psk31 etc   or  by  SDR  
 
PIC  code  is  available to  enable   = a =20 PIC based   keying  system  , the  PIC = would =20 be  Beacon - only  , the  software  also  has = the =20 QSO  mode , where  'any'  15 chrs   can be = sent =20 at  each  tx 
 
RX  , is  'only' possible  using  the  = windows=20 software  , and can  be   audio  = from  =20 soundcard , or by  SDR
 
The   RX , has   2   audio  = bands =20 , one  for  each  mode  , each  200  Hz = wide =20 ,  multi / simultaneous   decodes  are  = possible =20 in each  mode , within the  200 Hz  pass  band =
 
QSO    1200 / 1600  Hz
Becn    1600 / 1800  Hz
 
So  , for  VFO  control  of the  TX , = then =20 the  carrier  must  be  placed  to  = fall =20 inside the  required pass  band  , as the system  = uses =20 'usb''dial'  as the  definition  of the  = 'qrg'  =20 then   for  beacon   mode  ,   = 1601 to=20 1799  Hz would need  to  be added (better not at the band = edges=20 for tolerance may  drop signal  out the  pass = band) ,=20 normally    say  1700 Hz would  place  you = in=20 the  centre of the  pass  band
 
If the  Audio  drive  from the  software  = is =20 used , then the  carrier  frequency  will  be =20 placed  inside the  relative pass  band  , by =20 checking  for the  best s/n  'spot'  , this  is = completed by the  Rx routine , prior to  Tx and takes a =20 snap-shot , main function  to reduce collisions and  avoid = carriers=20 etc
 
So .......... If  used   by  VFO , then  = the =20 system  is  sopt frequency  , 2.5 Hz  b/w .
 
............If  the  carrier  placement  / = audio =20 tx drive  is  used, then  the  maximum allocated=20    B/W needed   is   200 Hz  for  = each =20 mode  , with   maximum   Tx  qrg =20 of   + 1800  Hz  from  the  dial-set - = usb =20

What are the actual frequencies that = are then=20 occupied by OPERA? As long as it is guaranteed that it's all below 2000 = Hz above=20 the dial frequency, 477 sounds like a good plan as a start. =
