Re: [digitalradio] Message ID in multipsk
Hello Tony, The S/N that you measure seems quite close to mine (-20 dB against -16 dB and -14 against -13 dB). In our measures, there is always a certain uncertainty because the noise is not really white after going through a sound card output and a sound card input. Moreover, in fact in all my tests, I accept about 2 % of errors because 0% error is impossible to reach (it can be approched but not reached). So there is certainly a small uncertainty about the 100% success. I think the 4 dB in RS ID of difference must due to the "burst" character of the RS ID as Path Sim introduces filters having a certain length, so... >If it's ok with you, I'll send a few audio clips so you can test the RSID and >Call ID at different SNR levels measured with PathSim. I'll >include the SNR >in the clip title. Thanks Tony, but I'm more confident on what I program. >the Multipsk S/N indicator to measure the signal-to-noise The Call ID S/N is not precise at all.

Re: [digitalradio] Message ID in multipsk [2 Attachments]
Patrick, Just checked the peak amplitude of the RSID / Call ID clips and they are both within 0.2db of each other. These are the audio files I used to determine the 100% throughput SNR for each mode using PathSim. I am sending you the files so you can test them at your leisure. The RSID (Mode ID) and the CALL ID are repeated 8 times on each clip. I repeated the test several times this evening and I still come up with the 6db difference between the two for 100% throughput. I should mention that I'm not using the Multipsk S/N indicator to measure the signal-to-noise; I'm using the SNR figures indicated by the path simulator. Tony -K2MO

I think I lost you Tony :( . No signal at all here. la5vna Steinar
Re: [digitalradio] Message ID in multipsk
Hello to all,
For information about the subject ("Message ID"), here is a mail transmitted
to the Multipsk Yahoo group.
73
Patrick
***
Hello to all testers,
There was a bug on the last test version, so I re-send the mail.
Some modifications have been made to the last test version:
RS ID, Call ID (Message ID)
RS ID
Due to the extension of the RS ID use, it is proposed a function which
allows to select a group of modes for which the user wants a RS ID detection
(function available by clicking on " ID ").
Message ID
Creation of a Message ID which permits to send small messages of 9
characters maximum which will appear in the waterfall of the other Hams. As
it works in background and as it is not related to any specific digital
mode, it can be useful, for example, in case of difficulty of doing a QSO.
Message IDs are not considered as true Call IDs and are not stored (they are
only displayed).
In Call ID, it has also been added the possibility to use space in free call
signs.
The last Multipsk test version is:
http://f6cte.free.fr/MULTIPSK_TEST_27_10_2009.ZIP
Paste this adress in your Internet Explorer or equivalent. Download the
file.
Create a tempory folder (C:\TEST, for example), unzip the file in it and
start C:\TEST\Multipsk.exe (the auxiliary files will be created
automatically).
Thanks for report.

Patrick
Note about the initial Message ID in the ID window
Initial Message ID (9 char. max): it is possible to send a message of 9
characters maximum (with the following set of characters (56) A..Z 0..9
space . ? = / + ! - , ; : % < > $ " ( ) * ), in background. As it is not
related to any specific mode, it can be useful, for example, in case of
difficulty of doing a QSO (thanks to the editor over the "Call ID" button on
the RX/TX screen). Message ID are not considered as true Call ID and are not
stored.
The main use is simply to send a short message in case in difficulty during
a QSO ("PSE PSK10", for example, to ask "To switch to PSK10" or "QRM +1K"
for "There is QRM, I increase the dial frequency by 1 KHz" or "STIL HERE" to
say that "I'm still here, even if communication seems impossible".
It could be also possible to exchange information between Hams doing other
QSO, or between a Ham not in QSO and Hams in QSO, for two reasons:
- the Call ID is received and transmitted in background so it can be used at
any time and in any mode,
- the Call ID appears to everybody in the bandwidth.
For example "Hi mode?" to say "Hello, what is the mode that you use" and it
can be answered "OL 32 1K" for "Olivia 32 carriers 1000 Hz".
It will be efficient to use Q code and Ham abbreviations and to use
punctuations to limit the number of characters:
- "?" question (a confirmation is required),
- "!" a strong demand is done by the Ham with who you are in QSO (an action
is required),
- ">" or "-" for "to increase the frequency",
- "<" or "-" for "to increase the frequency",
- "=" at the beginning without following space for "PSE " or "Please "
- "+" at the end for "I wait for an answer"
and why not net general smileys as ":-)" for "Smile"
