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..
Tnx-73-Graham

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 73-Graham G0NBD

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

2015 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 Links
