Re: LF: OP8 vs. WSPR in 4X

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

Can  only  do  but  try  ,   over  10 dB  was  quite a  margin , may  reach inland  usa  as  well  now ?

 

vx9bdq  is  nearly  on the  east coast  on 500   ....  which  poses  the  question  ,  is  OP8   viable on 500  , taking  the  qsb  pattern is much  shorter than 136 ..     not  been  tested as  far as  I  know ?

 

Tnx -G..

G, Stefan, LF,

Unfortunately the noise situation here on LF/MF is worse than it used to be but we should definitely try. QRN is stronger today as there's a storm approaching.

Ok Stefan

 

Yes  that  was   3 months  ago ! I think  it  came  as a  surprise  to many  136  operators  , that  the  band was  'open' 

 

A  OP32  run might  decode  into the Pacific   as  well  as over the pole  ... as long  as   no one has  stolen  Georges    mains   supply  cables  and  Laurence's   'pesky protons'   are  out to  lunch  :- )  

 

give a  few  days/nights   warning  for  Rx  stations  to  set  up ........

Hi G..,

Yes, maybe worth to compare! Good idea.
Chris/4X1RF: Are you arround here? Do we want to make such a test this evening? OP8 vs. WSPR in 4X?

Not seeing  a  decode  at  Haifa ?

 

These  where  made  in  July  using  OP8 ,  all  round   10 dB over the  OP32  min  decode  level  , would  be  interesting  to  repeat  now that  winter  has  (ish) arrived , to see  what  the  path  attenuation has changed by ?
