Ok Pete
I think you can extract more data , but
last time I tried , just got a empty
exel sheet .......... hopefully when Op
mode is running on the new
fixed VHF beacons , someone will take a look ,
but to date , nothing
73-G..
PS...This will interest you , there is
another driver etc for the dongle
.may be better than the one we are using
.....

Hi Graham
Is there any activity on the 28.076/8 op QRG? been monitoring, band open,
but nothing? Any comments?

Ok Stefan,
QRT , next to look at the reports , I
think tonight , minimum decode levels
are very close , the longer OP modes are much lower
, but the qsb on 500 tends to prevent gain being
made by extended times
Opera was designed to be sent by
a normal CW Tx ,
psk/fsk has a dB advantage , but
not all stations can send fsk or psk, ,
especially on 136 .. Without the racal ma1723
, it would be difficult to use fsk or
psk on 500 , ( not that psk is any
use on 500 .. too much phase shifting )
Not sure on the wspr settings , I dont think
the software can produce 12 Khz
, stations use ,pic-dds , that may
be a way ahead ?
But tonight , using the m-delt4 sound card , I
found the mixer monitor could be
used to combine 2 channels , so the
audio quality was much better than in the
past, with no IMP showing ...

Hi Graham, LF/MF, Nice setup to see which mode is
"better". Rik/ON7YD has done some tests a few months ago i remember. Now you
need many receiving stations who monitor these 2 modes to the same time as
well.Compared to WSPR i clearly find Opera an advantage regarding the
ease of keying the PA without the need of FSK.On LF i could run both
modes since i have the IQ upconverter (can WSPR set to an output frequency
of 12.5 kHz?? (to be mixed with 125 kHz)) but on MF i would need to extend
my setup...I really would like to join in tonite but i can't
