Shortwave Radiogram

Na kratko.
VOA Radiogram je končal z oddajanjem. Slika

Nekoč je zadeva šla z oddajnika Edward R. Murrow (North Carolina). Redno sem spremljal več kot polovico oddaj, a bilo jih je 222. Utrinek iz zadnje oddaje …

Slika

G. Kim Elliott se je upokojil in preimenoval svojo nekdanjo oddajo v Shortwave Radiogram.

Slika

Sedaj se oddaja z oddajnika Okeechobee (Florida). Za nas v Evropi je zanimiva frekvenca 11580 kHz in sicer ob nedeljah v času od 23.30 do 24.00 UTC, saj tako sklepam, ker imam dober sprejem samo v navedenem času. Pred 2 tednoma so začeli oddajati ob sobotah tudi z oddajnika Kostinbrod pri Sofiji (Bolgarija) na 9400 kHz in sicer v času od 16.00 do 16.30 UTC , kar je (zaradi bližine) precej zboljšalo kvaliteto prejetih sličic.

Za dekodiranje digitalnega besedila in slik imam na PC-ju nameščen program Fldigi. Sprejemnik je Sangean ATS-909X brez zunanje antene.

Z oddajnika Kostinbrod (Bolgarija) na 9400 kHz oddaja tudi The Mighty KBC Radio in sicer ob sobotah od 15.00 do 16.00. Dober radio. Ob cca. 15.30 spuščajo cca. 1 minuto MFSK32 signal. Zelo pohvalno od njih … v prvi oddaji so predstavili oddajnik s katerega oddajajo.

IBC - ITALIAN BROADCASTING CORPORATION ima posebno oddajo določene dni v tednu izključno namenjeno radioamaterjem.

http://ibcradio.webs.com/

Signal pošiljajo tudi z oddajnika Rohrbach Waal v Nemčiji na 6070 kHz, ki se na našem ozemlju lahko sliši brez dodatne opreme na navadnem sprejemniku, ki podpira sprejem na KV. 5-minutni MFSK32 signal oddajajo ob sredah od 18.55 ter ob nedeljah od 10.55 in se lahko dekodira besedilo in sličica.

From Radio Prague:
Czech car output up 5.1 percent in first half of 2017

27 July 2017

Czech car production rose by 5.1 percent in the first half of the
year with output totalling 756,468 vehicles, according to the
Czech Automobile Industry Association. The country’s biggest
producer, Škoda Auto, saw production rocket by 13.5 percent,
Hyundai’s output climbed by 0.5 percent, but there was a 15
percent drop from the TPCA joint venture plant. June production
was 4.7 percent higher than the corresponding month in 2016. The
figures show continued overall growth albeit at a slower pace.

The Mighty KBC Radio … Dober program ob sobotah od 15.00 do 16.00 UTC na 9400 kHz … in vedno prisotni radiogram na polovici oddaje …

Instead of the usual image, here are two KBC waterfall IDs
contributed by @howtophil .

Hit your Print Screen button when you see ENJOY KBC RADIO ...


Slika

Ujel sem drugo sliko. Za prvo bi mogel imeti nastavljeno večjo višino "slapa", ker je slika bila kar precej večja.
Našel sem tudi razlago za ta digitalni način oddajanja. Radioamaterji to zadevo zagotovo že poznate.

Video ID is different to RSID in that it can be seen by anyone using software with a waterfall display. Again, video ID is enabled in the transmitting software and it is not supported by every software. If you are watching a waterfall trace, you may, at the end of the transmission, see some text or even a crude picture in the actual waterfall - this is video ID and confuses many people who have not seen it before.

MFSK16: Tiny "Sprite" satellites

From ARRL.org:

Tiny "Sprite" Satellites Deployed, Transmitting on 70 Centimeters

31 July 2017

According to Scientific American, six tiny "Sprite" satellites,
each consisting of a 4-gram circuit board but packed with
electronics, were deployed in late June. The Sprites are the
brainchild of Zac Manchester, KD2BHC.

The Sprites went into low-Earth orbit as secondary payloads on
the Latvian Venta and Italian Max Valier satellites, launched
from India. Signals on 437.325 MHz from at least one of the
exterior-mounted Sprites have been received in California and New
York.

Manchester launched 104 Sprites into orbit in 2014 aboard
KickSat-1, but they failed to deploy.

@SamoBr

Nekaj malega že piše v mojem prvem sporočilu. Sicer pa bi lahko malce poguglal https://www.youtube.com/watch?v=FKZapCXJdAw

Zadeva izgleda dokaj komplicirana, ampak ni tako hudo.

Po domače … Najprej greš na http://swradiogram.net/

Na desni strani pod informacijami o času oddajanja, lahko vidiš tole:

To decode the digital text and images transmitted on Shortwave Radiogram, download Fldigi for PCs and the TIVAR app for Android devices from w1hkj.com. See also how to decode the modes.

Naložiš si na PC "fldigi". Priporočam ti, da najprej prebereš navodila http://www.w1hkj.com/FldigiHelp/index.html in nastaviš določene parametre od konfiguracije do konca, kot se zahteva.

Potrebuješ sprejemnik, ki podpira sprejem frekvenc na kratkih valovih (AM). Za Shortwave radiogram ne rabiš imet SSB.

Z audio kablom povežeš sprejemnik z zvočno kartico na PC-ju. Jaz koristim zunanjo (USB ključek).

Dovolj je da nekaj minut pred začetkom prižgeš sprejemnik, nastaviš na pravo frekvenco, zaženeš "fldigi" in nastaviš na napovedani način v "Op Mode" (večinoma je MFSK32), na računalniku se spodaj "v slapu" s kurzorjem postaviš na 1500 in to je to.

Sličice se shranjujejo v posebni datoteki "images" na PC-ju.

Kaj pa če nimam AM ? Imam samo SSB. Se s tem vseeno da sprejemat ?
Saj če oddajajo AM, s SSB sprejmeš samo 1 bočni pas. Nekako si mislim, da bi moralo iti, ampak bi bilo dobro slišati od nekoga, ki ima utečeno, če to res gre?

Deluje. Samo piči! Zvok je "ubijajoč". Par kHz levo ali desno, gor ali dol. Imaš priložnost že jutri (sreda) od 18.55 do 19.00 UTC poslušat IBC (in morda tudi dekodirat) MFSK32 signal na 6070 kHz. Sporoči, če si vsaj slišal kakšen zvok.

Ko že omenjaš SSB, na 4328 kHz USB lahko slišiš signal z Morse Code (CW) - izraelsko vojno mornarico iz Haife, ki ga lahko dekodiraš s fldigi-jem. Pri meni gre odlično. Sporoči, če ga slišiš (VVV DE 4XZ), oddajajo celo noč. http://www.numbers-stations.com/military/israel/4xz/
V vednost: Sem pravkar prestavil na AM in zvok se sliši. :D

Sporoči, če na 14070 kHz lahko čez dan slišiš karkoli. Če ja, potem si na pravi poti.

Zanimive teme tudi v zadnji oddaji Shortwave Radiogram. Signal v slapu je "bolgarski".

Slika

Prenašam v celoti zanimiv prispevek.

From ARRL:

Amateur Radio Participation is Key to University Solar Eclipse
Experiment

7 August 2017

The Solar Eclipse QSO Party (SEQP) is just a couple of weeks
away! The SEQP is a special operating event organized by the Ham
Radio Science Citizen Investigation (HamSCI) to study ionospheric
effects caused by the August 21 total solar eclipse.

During the SEQP, hams are being asked to operate on the HF bands
in a manner similar to a contest or QSO party. Let the HamSCI
researchers know where you plan to be and what modes you plan to
operate.

HamSCI scientists rely on data from systems such as the Reverse
Beacon Network, WSPRNet, and PSKReporter. Participants’ logs will
provide the contact and spot data that researchers at the New
Jersey Institute of Technology and at Virginia Tech will use to
study eclipse-induced ionospheric effects.

Event rules and operating procedures are available on the HamSCI
website: http://hamsci.org/seqp

http://www.arrl.org/news/rsvp-for-the-seqp

Kim's note: You can participate even if you do not have an
amateur radio license, or are otherwise unable to transmit.

At http://wsprnet.org, you can establish an account. Instead of
an amateur call sign, enter something like this: Your country's
prefix, SWL, and some numbers, so that your SWL call does not
duplicate an amateur radio call in your country.

Download the WSPR software from https://physics.princeton.edu/pulsar/k1jt/wspr.html

WSPR 2.0 will suffice and will be simplest to use.

When you have WSPR running, set Tx fraction to 0%, meaning all
receiving and no transmitting.

You can also select Upload spots: the stations you receive will
be reported to the WSPR database. The Band pull-down menu will
tell you which frequencies to tune. Make sure the band you are
listening to is selected, so that your reports to the database
have the correct frequency.

Also make sure that your computer's clock is set for accurate
time. One way to do this is to click on the clock in the bottom
right corner of your display, click Change date and time
settings, click Internet time, click Change settings, click
Update now.

During the eclipse, you might monitor 80 or 40 meters, bands
where DX is more common during darkness.

Use the Map feature of WSPRnet.org, select a band, set the time
period to 10 minutes, and refresh it often during the eclipse. If
you only want to see the stations that you are hearing, enter
your SWL call in Call box.

Experiment with different settings under Database and Map to get
different perspectives of station activity.

More information about using WSPR as an SWL is here: http://bit.ly/2fwzdg9
