''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' ?
