At the  moment , 'we'  have   2   beacon  systems  and    3  QRG  ,   one  combined  in   the  new  477  band  and   2 in the   existing   500 allocation.
 
With the   advent of the  new  477 band and  two   beacon systems  in operation , able  to  share the  same  operating   'dial set'  frequency  and  sound-card  resource ...Its may be  reasonable, now,  to   re locate  the  WSPR  frequency  to   500.000  KHz    dial  set  usb  , to  enable  dual   monitoring  of the  two  systems ?
 
As the  USA   is no  longer  using   WSPR on the  existing   frequency , there  is no longer the  possibility of  TA  reports
 
500 activity is now  tending  to  the  middle  502 upwards  with  qrss  beacons etc  in the  lower  section
 
As  477 Has become the   qrg , dial set usb  for both  WSPR and  OPERA , enabling  dual  watch , I would   suggest , for the  reminder of the  500  allocation , that    500.000 KHz , be  used  for  both  WSAP and  OPERA
 
DUAL WATCH 
 
In a  quick  test  , running  WSPR  and  Opera ( W/Fall -off- )  using  a   'old'   Intel  P4  3.8 GHz  p/c   cpu  usage  on average   of   15  %.
(note the  Opera  waterfall  plays  no  part in the  system  performance and is  for  indication only)
 
Q   Can  anyone  see  any  problems  with  this  re-alignment   on 500 KH z ? 
 
 
NEW  QRG   WSPR   +  OPERA 
 
500.000   KHz   usb-dial-set
 
477.000 KHz     usb-dial-set
