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 ..

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' ?
