LF: 477K OP8 Last 24 Hr

["Graham" <g8fzk@g8fzk.fsnet.co.uk>]

The  new  Opera OP8   mode  , set  for  477   has  provided  good  results  over the  last  day's  and  nights ,  one mode  being  set  for  each band  and  centre  tone of 1500 Hz  making  deployment simpler

 

At 8 minuets  , its  tending to  the  times  more  normally  used  at  LF VLF ect  without the  higher  equipment stability demands. With  the  improved  decoder  and  additional  3 dB  over the  previous  Op4 ,  , results   from  all  stations  look  good over the  two nights ..
