Stefan,
Opera only has the call sign in the
data , the web linking provides the other
services , range , bearing etc
this ensures the minimum data payload .
If you tests are not web linked , you
can arrange for a web based Pc to
simply run opera , in tx mode , this would
alert other monitors ,
As Op mode is free running , the web
linking will not affect the Tx or Rx performance
I had good results from the 750 feet
long wire at gb4fpr , at 100 feet
above ground sand or sea water , so
your dipole should work well , if its low,
then signals will be 'short skip' , the 600
ft delta loop gives good signals 1000
miles , but then nothing .. vertical
section is the main thing

Hi Graham,
Well, as often announced i want to do some
tests with a full size dipole for 630m. Maybe the signals will be very weak.
QRSS is not usual on MF and so Opera or WSPR will be useful for the tests.
However i would have no internet access during the tests...
BTW which
information is contained in one OP message? Just the callsign or the
callsign+locator?
73, Stefan
Thanks Stefan
Main thing is , that all stations have the
same mode set , but if you are using
the windows software , the internet beacon
will show the mode , OP8 or OP32 ... this
is where the PIC based systems have
a problem. but if the tx is remote , its
possible to simply run Op on a web
linked PC to beacon via the web ..
Monitors can run X2 Opera , one
set to OP8 , the other OP32 , with some CPU
overhead , but not a problem on a 'new' pc better , just
the one session.
If you have a day selected, then can post
to the user groups, to ensure the maximum number
of Rx stations
