ALL

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=20

500 activity is now  tending  to  the  middle  502 upwards  with  qrss  =
beacons etc  in the  lower  section=20

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=20

DUAL WATCH =20

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  =
%.=20
(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 ? =20


NEW  QRG   WSPR   +  OPERA =20
