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
