Warbler 1k2 BPSK demodulator

 

Warbler_1k2BPSK_demodulator

Warbler is a Java software which can be used to demodulate a 1200Bit/s AX.25 BPSK signal. The software is from 2007 and made by PE4WJ. Warbler generates a KISS-file which can be imported to several telemetry decoding software made by DK3WN.

I have used Warbler for ex. QB50p2 satellite with very good result. I think the software is very good and more simple to decode signal compared with MixW.

Warbler är ett litet Java-program som används för att demodulera 1200Bit/s AX.25 BPSK-signal. Programmet har ett par år på nacken, det är från 2007, men fungerar utmärkt. Det är skrivet av PE4WJ. Warbler genererar även en KISS-fil som är en binär fil med data. Filen importeras sedan i ett av flera program för att avkoda telemetri som DK3WN har gjort.

Jag har provat Warbler för satelliter QB50p2 och det fungerar utmärkt. Jag tycker det är mycket enklare att använda än MixW som är ett av de få program som kan användas för liknande uppgift.

Dock har jag inte sett någon möjlighet att skicka ljudet internt i datorn till Warbler utan man måste koppla hörlursutgången till mic-kontakten (detta i fallet då man kör SDR-programvara). Detta löses enkelt med en förgreningskontakt på hörlursutgången så att man fortfarande kan ha medhörning. Se bild nedan. OBS! Om du har en separat radio behöver du självklart inte denna lösning utan då kopplar du bara hörlursuttaget från radio direkt till mic-ingången på datorn.

AMSAT Annual Meeting Remote Participation via EchoLink

Detta år går det att vara med via EchoLink på vissa föredrag på AMSAT-NAs årsmöte. Läs mer nedan:

The 2014 AMSAT Symposium will be held Friday, Saturday, and Sunday,
Oct 10-12 in Baltimore.  The Annual Meeting will be held Saturday
afternoon from 15:45 – 17:15 EDT (19:45z – 21:15z) and will be
broadcast via EchoLink on the *AMSAT* channel.  The Annual Meeting
includes a report to the membership by the President and Senior
Officers and includes a question and answer session where members may
ask senior officers and BoD members questions.  Echolink participants
may send questions using the text messaging feature of EchoLink.

Some of Friday and Saturday’s Symposium presentations may also be
available via EchoLink, as these will be used to test the EchoLink
hardware, software, and Internet connection.  See
http://www.amsat.org
for the Symposium schedule and the titles and times of the
presentations.

If you haven’t used EchoLink before, you need to download the
software and validate your license *NOW*.  EchoLink use is restricted
to licensed radio amateurs, because EchoLink is frequently used to
remotely key amateur radio transmitters and repeaters.  The
validation process is used to prove that you are licensed.  See
http://www.echolink.org
for more information. EchoLink software is available for free for
Windows, Linux, OSX, iPhone, iPad, and Android.  An Internet
connection is required.

Once you’ve started EchoLink, search for the *AMSAT* channel (node
#101377), select it, and “Connect”.  The channel name includes
asterisks (*) both before and after AMSAT.

4M Lunar Ham Radio Payload Shipped
Ghislain Ruy LX2RG reports the 4M Lunar flyby amateur radio payload
was shipped on Thursday, October 2 and he departs for the Xichang
Satellite Launch Center on Sunday, October 5.

He says the lifetime of 4M is quite an unknown: it may be as short
as 100 hours (so at least to the Moon) and could extend for some
weeks if the attitude is favorable.

It is now known that the spacecraft will not re-enter the Earth
atmosphere after the flyby but instead enter a wonderful orbit. You
will find information animations and some JT65B test files at

https://cloud.luxspace.lu/public.php?service=files&t=33c4a21c09ba3736
a55fc09896e463f6

The launch will be transmitted by CNTV/CCTV:
http://www.cntv.cn/ or
http://english.cntv.cn/ or
http://english.cntv.cn/live/p2p/index.shtml

LX2RG says the team are setting up their ground station, and are
especially looking for southern hemisphere stations: ZS, VK and ZL,
Southern America continent mainly, as they will be placed first hand
for the early hours.

Launched is planned in a narrow window at 17:59:xx UTC on October 23
and flyby is to occur nominally on October 28 at 00:33 UTC.
4M is planned to start transmissions at 19:17 UTC, possibly with 10
minutes additional delay.

K1JT has developed a special version of WSJT. In addition of all the
features of the standard version, it includes also the display and
logging of the dT to three decimal places and the logging of the
manual offset that can be entered in JT65B modes. This version should
be used by all who wants to participate to the ‘Multilateration’
experiment.
The participant to this experiment should also make sure that the
clock of their PC stays synchronized to the UTC time. Desired
accuracy should be within 1ms and within 10ms at the very least. Use
of NTP synchronizing software is a must.

The special version can be downloaded with the following links:

https://cloud.luxspace.lu/public.php?service=files&t=2720825f74104b31
ebd699dcc0fd6268

The LuxSpace ground station comprises 2 x 8 element crossed Yagis
from Joachims antenna (with an improved design to lower the back
lobe), a SSB.de LNA and Yaesu antenna rotators.

Best regards.
Ghislain Ruy LX2RG
