John,

 

Yes  , the  day and the  time  are  not  ideal , but  any input  is  welcome ,  there  is  not  a  overview  of intended  participants  as of yet..

Thanks Andy
 
Thinking aloud , you may  be  too  far south  for  the  TF3 path  on 477 ,   Finbar EI0CF  will  be sending  on 477  , [Ideally  placed ] ,  I intend  to  TX also  on 477 , 
Hopefully  on the   1000  mile  arc  from  TH3  ,   477 tx  stations  from    PA  - LA  - SM zones  would be  ideal ...
 
That  puts your  location , best placed    for the  200/300  Miles   shorter   southern  skip  ?
 
There  is  no  central  control  as  such  for  Opera , but the  3  band Rx  would  perhaps  be the  most valuable  option ?
 
Noting,   Top band  being perhaps  the  next  in line  interims of  measurable  effect , that  would  provide the  Russian  Top band users, a  well  placed  monitoring  point as  well  as  any  more  local  activity  from  Uk  or  EU  etc
 
If you  take that  option Andy ,  that  covers  the  477 band  North  TH3HZ  and South  Rx, yourself,  quite  well ,  additional  Rx stations   in the  shorter  ranges would  complete the  monitoring  requirements ?
 
 
 
Thanks

Hello Graham.
 
I want to participate to the OPERA test  during  the  morning  of  Friday  20  March   0800z  to  1200z.
 
But I have 2 choices. Please tell me what is the best one for you ?
 
1.      I can transmit, but only one one band, 630, 160 or 80 meters ;
 
2.      Or, I can receive on the 3 bands at the same time. After the event, I’ll send all the OPERA reports by Internet using any file format (txt, xls, pdf.....).
 
I hope that many stations be active for this event.
 
Best 73.
 
Andy F6CNI – JN19QB.

Partial solar eclipse propagation experiment, March 20th 2015
 
Call  for  Opera users
  
There  is  a  unique  opportunity  to  participate  in  gathering  propagation  data  during  a solar eclipse, occurring,  during  the  morning  of  Friday  20  March   0800z  to  1200z.
 
The  Opera  system is  well  suited to  the requirements   and in liaison  with the  RSGB project  coordinator , Steve G0KYA , Opera  mode  is  added  to  the  list of  experiments.
 
User participation: A change from the normal  
 
Its requested  MF and 160  participating  stations , elect  to  be  either  Tx  or  Rx  only ,
 
Due to the  short length of the  event, round 4  hours, to  maximise  the  quantity and quality the of data  produced  from the  477KHz and 1.8 MHz bands,
 
Tx Stations are requested to send at 100% no beacon timer and no CW i/d,
 
Rx Stations are requested to maintain ‘Fixed band’ watch over the time window. 
 
[Rx Stations ,  Copy  and  paste  the  local  decode  results to  text  file  as  back up to  the  PSK-Map  data  base]
 
Three sections of the spectrum are of particular interest:-
 
MF      477 KHz / OP8    Tx @ 100%  No  CW ID
 
HF       1.8MHz  / OP4 ,  Tx @ 100%  No  CW ID
 
HF       3.5 MHz / OP2  , 7 MHz / OP2    Normal  operations
 
One of the  main  areas of  interest is the   North /  South  path  straggling  the  line  of Totality, this  being  roughly central to  a  1000  mile  path from the  UK/EU to  Iceland.
 
MF: 477KHz ‘Totality Path’: Halldor  TF3HZ   has undertaken to  establish a web-linked Rx monitor   for  477KHz  OP8  and  will  set up  in the  week  previous to  the  event.
 
MF: 477KHz  Inter  ‘UK / EU’: Stations are also  invited to  join the  experiment ,  noting  , Tx / Rx stations  are  requested to  follow  the  100% Tx  and   Rx  continuous  availability.
 
HF Bands
 
Opera  is  one of  many  systems to  be  deployed  during  the  event  on HF .
 
1.8  OP4  Operations  requested to  follow  the  MF 477 KHz  format
 
3.5  and  7 MHz bands ,  deploying  OP2  mode ,  normal  operations
