Good results Stefan ! ,
This is interesting as -35 (ish)
and definitely -31 dB are inside the minimum
decode level of OP8 , being 4
and 9 dB over the Op32 limit.
seems Mike did not decode , but I think he
is round -14 / -15 dB lower , so that would
of fallen short ..
Looks like it was a good night all round

''to
need endless for one decode! 32 minutes is not endless'' ......?
Of
course , a pixel is one thing , the full call is
the other :)
what we can see is , not all the
pixels show all the time , I think is is
predicted by Mr S law's of propagation ? , so as
to the call this is open to debate :(
The OP
mode is a data mode , running in single pass and
can make use of fast qsb/ripple
Yes 32 is a
long time , but we think is the lowest s/n
single pass data move available for use at the
moment
another 5 or 6 db could be
gained from fsk / psk modulation , but then , that puts it
outside the user group
OP32 at -40 dB s/n
offers the best possible range for the
'average' 136 station , and the possibility of
''extended'' range for the slightly larger installations :))
Hopefully the long range monitors are
running Rx OP8 and OP32 , I see Mike has
just started sending OP32 at 100% cycle ..

G..,
OP32 appear to need endless for one
decode! 32 minutes is not endless and transmitting a call in QRSS-60 takes
even longer but when i start transmitting in QRSS-60 it takes not longer
than 1 minute until i see it on the YO/4X1RF grabber...
BTW the
OE3GHB grabber is back! http://members.aon.at/grabber/
Tonite there are OP8 and OP32 decodes. I will also TX in OP8 since
this is faster... Confusing.

Ok Mike
TF3HZ is showing
OP32 at the moment along with some in
the Moscow triangle , I think as long as your 3 Hz apart,
then each will decode , so that should not
be a problem..

Yes, 136.000kHz USB dial setting. I usually also
specify my actual
transmit frequency in case another transmitting
station wants to
avoid that frequency, or perhaps someone wants to
look for me with
Argo or SpecLab.

Mike
Is that 136.000
KHz usb 'dial set' ?
