IARU Announces Frequencies for Korean Ham Radio CubeSat OSSI

The IARU amateur radio satellite frequency coordination panel has announced the frequencies for the OSSI-1 CubeSat developed by Hojun Song DS1SBO. Artist and radio amateur Hojun Song DS1SBO has spent 7 years developing his Open Source Satellite Initiative satellite OSSI-1. He has designed and developed it from scratch using readily available components rather than expensive space qualified hardware. It has a beacon in the 145 MHz band, a data communications transceiver in the 435 MHz band and carries a 44 watt LED optical beacon to flash Morse Code messages to observers on Earth. OSSI-1 is planned to launch on April 30, 2013 into a 575 km 64.9° inclination orbit on a Soyuz-2-1b rocket from the Baikonur launch facility in Kazakhstan along with the Bion-M1, SOMP, BEESAT 2, BEESAT 3 and Dove-2 satellites. The IARU amateur satellite frequency coordination panel has announced frequencies for a downlink on 145.980 MHz and an uplink/downlink on 437.525 MHz.

The contact will be a telebridge operated by IK1SLD, located in Northern Italy. Interested parties in Europe are invited to listen to dowlink signals on 145.800 MHz FM. The contact will be conducted in English.

The contact will be broadcast on EchoLink AMSAT (node 101 377) and JK1ZRW (node 277 208) Conference servers, as well as on IRLP Discovery Reflector 9010. Read more.

The Universal Postal Union (UPU) introduces new International Reply Coupon (IRC)

The Universal Postal Union (UPU) has introduced the newest model of the International Reply Coupon (IRC): The Doha model -- so named for the 25th Universal Postal Congress that took place in Doha, Qatar in October 2012 -- will replace the current model, known as the Nairobi model

The Doha model IRC will go on sale on July 1, 2013. It is valid for exchange it until the end of 2017. The Nairobi model -- first issued on July 1, 2009 -- remains valid until December 31, 2013. IRCs are exchangeable in every UPU member country for stamps representing the minimum postage for an ordinary priority letter-post item or airmail letter sent abroad for a reply. According to the UPU, 120 postal systems around the world worldwide had issued more than four million Nairobi IRCs with a total value of approximately $5 million as of October 31, 2012.

The Czech Republic has won the UPU's competition to design a new international reply coupon (IRC), beating 13 or countries.  The work of Czech artist and graphic designer Michal Sindelar will display the theme "Water for Life", chosen to reflect the 2013 United Nations International Year of Water Cooperation in 2013. The new "Water for Life" IRC will go on sale on 1 July 2013. Postal customers will be able to exchange it until the end of 2017. It will replace the current coupon, known as the Nairobi model, which was first issued on 1 July 2009 and will remain valid until 31 December 2013.

How does it work?

When one writes to a stranger and requests a reply, it is considered polite to enclose a self-addressed stamped envelope. This works well when both persons live in the same country; however, if they are from different countries, the enclosed postage stamp will not be valid. This technical problem was solved in 1906 when the Universal Postal Union, during its Congress in Rome, introduced the International Reply Coupon service. As the service began before the days of airmail, the earliest coupons could only be redeemed for a single-rate ordinary postage stamp to a foreign country. In terms of today's UPU Convention, International reply coupons (IRC) are exchangeable in all member countries for the minimum postage of a priority item or an unregistered airmail letter sent to a foreign country.

The UPU's International Bureau processes several million coupons each year and deals with of all accounting aspects. The International Bureau does not sell IRCs directly to customers; they must buy them from their local post office. Although Posts are not obliged to sell IRCs, it is mandatory for Posts to exchange the coupons. If a Post does not sell IRCs, it is possible to purchase them in a post office located in a neighbouring country.

My second DV QSO

Article written by Julian Moss, G4ILO, as published on AmateurRadio.com on February 4, 2013
 
"Just as I was finishing writing my previous post I heard someone else calling on the 20m DV frequency. It was Elie, OD5KU.  Yesterday I had heard him working a French and then a Dutch station but signals were weak and not good copy at all.
 
I replied to Elie but he couldn't make out my call. I tried several times and was about to give up when he called again with solid copy. Perhaps he had turned his beam my way. I tried calling one more time. This time he heard my reply and we had a good QSO with several periods of solid copy punctuated by occasional break-ups. These occurred when QSB took the  digital signal down to near-invisibility in the FreeDV waterfall. I doubt that good SSB copy would have been possible at those times either. I managed to make a recording of the end of this QSO so you can get an idea of the audio quality. It was recorded off-air using my Olympus digital voice recorder, then played back using the mic input of the USB sound dongle to make an MP3 file. 
 
Given the way it was created I think the clip is quite a good example of the FreeDV audio quality. As you'd expect from a digital signal either it's all there or you just get gobbledygook. It doesn't degrade gracefully. Is this the future of ham radio? Have a listen and let me know what you think."

DX Code of Conduct

  • I will listen, and listen, and then listen again before calling.
  • I will only call if I can copy the DX station properly.
  • I will not trust the DX cluster and will be sure of the DX station's call sign before calling.
  • I will not interfere with the DX station nor anyone calling and will never tune up on the DX frequency or in the QSX slot.
  • I will wait for the DX station to end a contact before I call.
  • I will always send my full call sign.
  • I will call and then listen for a reasonable interval. I will not call continuously.
  • I will not transmit when the DX operator calls another call sign, not mine.
  • I will not transmit when the DX operator queries a call sign not like mine.
  • I will not transmit when the DX station requests geographic areas other than mine.
  • When the DX operator calls me, I will not repeat my call sign unless I think he has copied it incorrectly.
  • I will be thankful if and when I do make a contact.
  • I will respect my fellow hams and conduct myself so as to earn their respect.

FreeDV | HF Digital Voice for Radio Amateurs

FreeDV is a GUI application for Windows and Linux (MacOS and BSD are in testing) that allows any SSB radio to be used for low bit rate digital voice.

Speech is compressed down to 1400 bit/s then modulated onto a 1100 Hz wide QPSK signal which is sent to the Mic input of a SSB radio. On receive, the signal is received by the SSB radio, then demodulated and decoded by FreeDV.

FreeDV was built by an international team of Radio Amateurs working together on coding, design, user interface and testing. FreeDV is open source software, released under the GNU Public License version 2.1. The FDMDV modem and Codec 2 Speech codec used in FreeDV are also open source.

Why FreeDV?

Amateur Radio is transitioning from analog to digital, much as it transitioned from AM to SSB in the 1950's and 1960's. How would you feel if one or two companies owned the patents for SSB, then forced you to use their technology, made it illegal to experiment with or even understand the technology, and insisted you stay locked to it for the next 100 years? That's exactly what was happening with digital voice. But now, hams are in control of their technology again!

FreeDV is unique as it uses 100% Open Source Software, including the audio codec. No secrets, nothing proprietary! FreeDV represents a path for 21st century Amateur Radio where Hams are free to experiment and innovate, rather than a future locked into a single manufacturers closed technology.
