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
