!
All,
Opera 136 Up Date
Following on from the previous, some
interesting developments , on 136 , If your station
is web-linked , then in either Rx
only , Tx only or Tx/Rx you
will show on the PSK-Reporting map, this
was set to ensure the status of both Tx
and Rx stations was available to all. after
all one is no use without the other !
As there is still no 'dedicated
storage' for the on-line data , If you wish
to monitor activity on a particular band , you
can simply run Opera , set to the required band
and check the 'spots only from' box , you
will then have a local copy of band
data . some stations have added text
to the beacon 'test only - no RF' or similar to
prevent misinterpretation.
NB : These are full DATA call sign decodes ,
so are the bare minimal exchange
required to claim a qsl or qso for 1
or 2 way , Opera is purely based on Data processing
and Digital signal processing and has 'no' deep
search or fuzzy logic decisions to assist
in the data recovery , similarly for the QSO
option, allowing 15 Chrs to be send in 120
seconds at a nominal -20 dB s/n (ref to
Sim-Path simulation software)

This seems to be OP32 mode , but
monitoring stations can run 'two'
opera sessions , from the same sound card/pc ,
set OP8 and OP32
JH1GVY recent Tx addition to the JA
group of 8 136 beacons regularly showing
on the psk map
