Stefan,
 
Opera  only  has the  call  sign  in the  data , the  web linking  provides  the  other  services  , range , bearing  etc
this  ensures the  minimum  data  payload .
 
If  you tests  are  not  web linked , you  can  arrange  for a   web based  Pc to  simply  run opera , in tx  mode ,  this  would  alert  other  monitors , 
As Op mode  is  free  running  , the  web linking  will  not  affect the  Tx or Rx  performance
 
I had good  results  from the  750 feet   long  wire  at  gb4fpr ,  at  100  feet  above  ground  sand  or  sea  water , so  your  dipole should  work  well , if  its  low, then  signals  will  be  'short skip' , the  600 ft  delta loop  gives  good  signals  1000  miles  , but  then  nothing  ..  vertical  section  is the  main thing

Hi Graham,

Well, as often announced i want to do some tests with a full size dipole for 630m. Maybe the signals will be very weak. QRSS is not usual on MF and so Opera or WSPR will be useful for the tests. However i would have no internet access during the tests...

BTW which information is contained in one OP message? Just the callsign or the callsign+locator?


73, Stefan

Thanks Stefan
 
Main thing is , that  all  stations  have the  same  mode  set , but if  you  are  using   the  windows  software , the  internet  beacon  will  show  the  mode  , OP8 or  OP32 ... this  is  where  the  PIC  based   systems  have a  problem. but  if  the  tx  is  remote , its possible to  simply   run Op  on a   web linked  PC to beacon via the  web ..
 
Monitors  can  run  X2   Opera   , one set to  OP8  , the other  OP32  , with some  CPU overhead , but not a problem on  a  'new'  pc better , just the  one  session.
 
If you  have a  day  selected, then  can post  to the  user groups, to  ensure  the  maximum  number of  Rx  stations
