Thanks Jan for running the beacon
Unfortunately there was change of version in the middle and things
got a little out of hand ..however , the psk-map linking is nearly
complete and the latest version now reports the distance .... that
zip will only have the one version ..
Yes I noticed the OZ4KPC , nothing at my qth .. :(
The YV could be version problem .. allsorts of crazy decodes ..
I did see your signal a few times but no decode , 20 watts from
this side decoded with you a few times . i was using the MA1723 +
skanti amps with the audio tone feed , can use the cw key , but it
needs a second com port to hold the station in TX ..or it runs
break-in .. which tends to chatter the relays at slow speed .
Yes , its a little odd , but , the idea was a data mode that could
uses a simple cw tx , the race to the noise floor , I suppose was not
too unexpected , however , Gary proved that a little DSP helps to
get the signal across :)
Of course any of the hybrid modulation systems will give s/n
enhancement , but this is a fun for all mode and works with any home
made cw tx or vintage xtal valve set

Graham,
Well I think it's a matter of conditions.
In the past I could decode your ROS MF transmissions, not on a daily
basis, but MF is is very depending sometimes on a certain duct condition.
Nicolas has very sensitive location at least he must have a low noise
situation..
Surprisingly I received OZ4KPC rather strong, that strong that a live CW
QSO would be no problem.
Just now @ 23:22 YV0OFP 500 Op2 came in with an increadeble +17 dB!
(Local pirate call??)
It's a bit frustrating about Opera not knowing what it is actually doing
and how it works.
Just pushing buttons and looking for results is like a magnetron dinner.
Could be tasteful but you don't know why.
I'm using an old KWD TS-440 driving a QTX transmitter in split mode about
25W in a dense urban area.
TX on 2MHz which goes into a divider by 4 resulting 500kHz.
Using the CW keyer. So moving the carrier to an empty slot is not
possible. Anyway the software decision will be divided by 4.
A ringmixer arrangement should replace this soon. Which makes it more
flexible for other modes.
Dutch "OFCOM" were asleep and dictated to use morse only.
A CW id at the end of the transmission will certainly please the Dutch
authorties.
Think this eve was usefull showing some bugs and some user wishes.
However I can't determine how usefull and better Opera is in relation to
other deep noise programs.

NNNN

Jan,
Still no decode from you , but see your reaching F4DTL , may be
round 2300 I should see you ?
When using audio drive , the software has a scan facility , that
places the carrier in a empty slot .. with vfo control , its pot
luck , but the separation is very small so it should not be a real
problem ..
I think the beacon timer is fixed and tx occurs after the pre-set
period
Yes it will decode multiple signals / both speeds at the same
time
CW ... well I am decoding PA0A (AA) under the noise for most of
the night
Early days yet ..
