Hi LF, Ebnauters, Group

i my previous post, i have communicated a wrong information about EbSyn= ch=C2=A0 and i'm very sorry for this. Many thanks to Markus Vester for = his clarification in a private mail.

I wrote: =C2=A0 EbSynth also cures soundcard's glitches by using an internal feedback.

That is not true. As clearily indicated by Paul Nich= olson on the webpage http://abelian.org/ebnaut/ebsynth.shtml, an extern= al feedback signal may be connected to the channel 2 of the soundcard=C2=A0 to stabilise the phase.
On my setup,=C2=A0 the=C2=A0 -x option is not specified (int= ernal feedback active) and i have only a 10 kHz reference signal connected = on channel 1. Phase recover cannot be done with the 10 kHz tone alone becau= se the phase,=C2=A0 after a dropout or buffer overflow,=C2=A0 would be ambiguous.

From P.N. website

Sound card overruns and underruns must at all costs be avoided. If one occurs, the phase will be lost and there is no way to recover. If the ALSA driver reports overrun on input or underrun on the output ebsynth will exit. There is no point in trying to recover. USB sound dongles may lose USB packets and the driver is not notified. If this happe= ns on the reference input the phase will be lost and will not recover. The output will experience a phase step and will settle down at a new phase. If a USB packet is dropped from the output, there will also be a phase step but if external feedback is in use, the phase will recover to its original value.

Sorry again for my error.

My night '114 characters' trasmissions were completed at= 05.00 UT . I hope in a report. Thanks to whom have attempted the decode.

first of all, thanks = to Stefan and Marco for reports and to the US' friends for their effort= s in trying to decode my=C2=A0 5 characters message of yesterday.

Th= e Ebnaut signal is generated here using Paul Nicholson's linux EbSynth = version 0.7c.
This program generates a 1524 Hz tone (referen= ced by a 10 kHz coming from Neo-8 GPS) bpsk modulated with a sigmoid phase = slew keying.

Thanks to Paul latest modifications, 'EbSynth' has als= o a PTT management with a programmable timer for carrier ON/OFF before and = after bpsk.=C2=A0 See attached the screenshot of the program EbSynt running= here.
Great job Paul !

The tone is sent to= my 'vintage' SAILOR exciter setted to dial 136 kHz USB.

Hi Domenico,

No problem to copy the 5 char message, see attachment.
I tried to decode the 200 char message but get no decode. Can you try 8K19A and 100 characters first? It looks like it was to early in the night for that message, 1 hour later the propagation is better it seems. Are you using SpecLab for transmitting the message or ebsynth?

73, Stefan
