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..

I may not be able to participate in the experiment, but it occurs to me that report from outside the area expected to be affected might also be useful.

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
