CubeSat with Amateur Radio Transponder Set to Launch on February 15

AMSAT-UK and AMSAT-NL have announced that at the Nayif-1 1U CubeSat, which includes a full FUNcube communication package, is set for launch on an Indian PSLV launch vehicle on February 15 at 0358 UTC.

PSLV Flight C-37, will carry more than 100 satellites into orbit.

Nayif-1 carries a U/V linear Amateur Radio transponder for SSB and CW and a telemetry transmitter. The initial plan called for a late-2015 launch.

Nayif-1 was a joint project of the Mohammed bin Rashid Space Centre (MBRSC) and American University of Sharjah (AUS). The United Arab Emirate’s first nanosatellite, Nayif-1 was developed by Emirati engineering students from AUS under the supervision of a team of engineers and specialists from MBRSC. The partnership between the two entities was aimed at providing hands-on satellite-manufacturing experience to engineering students.

Telemetry will be transmitted on 145.940 MHz, 1.2 KB BPSK (FUNcube standard). The SSB/CW transponder uplink passband is 435.045-435.015 MHz, and the downlink passband is 145.960-145.990 MHz.

AMSAT-UK is seeking post-launch reports from stations around the world, especially during the first few minutes and hours after launch. It is anticipated that the first signals may be heard in North America during the mid-evening hours on February 14 (local time).

A mission-specific telemetry dashboard is available. Information can be found on the web in PDF format at, https://funcubetest2.files.wordpress.com/2017/02/nayif-1_dashboard_notes_release_1-0b.pdf.

In a manner similar to that of the FUNcube-1 dashboard, this one will be capable of uploading the telemetry received to a central data warehouse. More information on the telemetry dashboard is available, as is a test file.

Initial spacecraft operation will be in a low-power “safe” mode, with just the telemetry transmitter activated.

I have had some fun tracking CubeSats in the past, and it is especially fun to watch your data appear on the dashboard history. And of course you are helping the research to boot!

ISS SSTV: Receiving images from space

(Source: Southgate ARC)

Slow-scan television (SSTV) transmissions are planned from the International Space Station (ISS) on February 13-14, 2017

The SSTV images will be transmitted as part of the MAI-75 Experiment on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is thought they may use the PD-180 SSTV format.

The MAI-75 activities have been scheduled for the Russian crew on Monday, February 13 from 09:25-18:00 GMT and Tuesday, February 14 from 11:25-16:30 GMT.

Note the ISS transmissions on 145.800 MHz FM use the 5 kHz deviation standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try the wider filter.

The ISS Fan Club website will show you when the space station is in range http://www.issfanclub.com/

95 Years: A celebration of radio station 2MT

Many thanks to SWLing Post contributor, Jim Salmon, who shares the following press release:

95 years ago on Tuesday 14th February 1922, a small group of young, gifted, charismatic – & perhaps slightly irreverent – Marconi employees turned on a medium wave transmitter in a ‘long low hut’ in a waterlogged field in Writtle, Chelmsford, & began a year long experiment which is now regarded as the birth of broadcasting in the UK. Led by the irrepressible Captain Peter Pendleton Eckersley, the 2MT team broadcast regularly every Tuesday evening, & what started as a request for a station for ‘calibration purposes’ for the fast growing number of radio hams, transformed into an entertainment programme like none before.

A small group of us are celebrating the upcoming 95th anniversary of 2MT – ‘Two Emma Toc’ – with a combination of amateur radio transmissions & an internet radio service. On the 12th & 14th February, members of the Chelmsford Amateur Radio Society will be operating a special event amateur station using the callsign GB95 2MT, & these transmissions will emanate from the very same ‘long low hut’ now preserved at Sandford Mill Museum in Chelmsford, UK.

On the 12th, 13th & 14th February, radio enthusiast Jim Salmon will be running an internet radio service ‘Radio Emma Toc’ with radio related documentaries, vintage comedies, & 5 hours of live programming each day including a visit to the long low hut. We are not attempting to re-create 2MT, more a case of having fun, paying tribute & looking ahead to greater celebrations for the centenary in 2022.

We invite radio hams to join us on the bands & listeners to join us on ‘wired wireless’ (Peter Eckersley’s futuristic 1930’s phrase for what we now call the internet) to remember 2MT & pay tribute by having fun on the radio. Email us at Radio Emma Toc with your radio memories during our live programming & we will say hello to you !

New book: History of the Birdlip Aeronautical HF Communications Complex

Many thanks to SWLing Post reader and author, Colin McKeeman, who shares the following announcement:

As a mature aviation historian and keen HF monitor since the mid-1960’s, as you will note from my blog this has prompted me to produce this detailed record of the [Birdlip Aeronautical HF Communications Complex, U.K.] stations activities.

[…]The activities of this station are currently handled by ‘Shanwick’ (Shannon and Prestwick) for air traffic on the North Atlantic.

I attach a summary of its content which may help to clarify the scope and nature of this publication.

Guest Post: Radio Australia, and a sea story

Many thanks to SWLing Post contributor, John Harper (AE5X), who is kindly allowing me to re-post the following article originally published on his excellent blog:


Radio Australia, and a sea story

by John (AE5X)

From London Shortwave: “It’s official: Radio Australia are no longer on shortwave…”

Four submariners on a surface ship (1989-1990)

Nine of my 10 years in the Navy were spent in the Submarine Service – the other year was spent aboard a research ship operating between Perth, Australia and Singapore. Our mission was to make detailed contour charts of the sea floor in that area using precision fathometers and new-at-the-time GPS.

The detailed charts allow US submarines to get navigational fixes by correlating their soundings with the data we had collected without having to come to periscope depth for a satellite fix, thus the need for a small contingent of submariners on a surface ship. Gathering this data required the ship to stay at sea 28 days at a time, going back and forth in straight lines across the eastern Indian Ocean. At the end of those 28 days we would pull in to either Fremantle or Singapore for a week, then out again.

We enjoyed the sunlight, fresh air and the presence of civilian women onboard (oh, the stories I could tell if this weren’t a family-friendly blog!) but what we missed – and missed greatly – was news from the world. Big things were happening at a fast pace in those days as the Iron Curtain began to crumble and we knew nothing of it for long, event-filled month-long chunks.

There is a huge psychological disconnect that comes with being isolated from the world for a month at a time. We starved for news and any kind of connection to the outside world so, during a port call to Singapore, I bought a Philips D2999 shortwave receiver. It was small enough for shipboard life, ran on AC or batteries and even had a BFO for occasionally listening to hams.

After having it for a few days and mentioning to the other crewmembers various things that were happening around the world, their interest grew and I eventually moved the radio from my stateroom to a common breakroom so that anyone could listen whenever they wanted. For a while we even had a printout of news events – a one-page daily newspaper – that we posted in various locations throughout the ship. Many of us were glued to the radio during the week of events in December 1989 that culminated in the Christmas Day execution of Romanian President Nicolae Ceau?escu.

Some of that news came from the VOA, some from the BBC and even from Radio Moscow. All had good signals into the Indian Ocean area at times. But regardless of time of day or ionospheric conditions, Radio Australia was always there, like a beacon – reliable, dependable and with great fidelity due to no selective fading. It was our primarily source of news.

Frequencies of many stations and the best times to hear them were posted near the radio but everyone knew our two main frequencies for Radio Australia without having to look it up. We listened to Radio Australia so much that the announcers eventually lost their accents.

The beauty and utility of shortwave was introduced to people who otherwise would have had no interest in it. Thanks mainly to Radio Australia, we not only knew what was going on in the world, more importantly, we felt more a part of it and less isolated than we had been before.

The end of Radio Australia and so many other shortwave stations marks the end of an exciting era. What an amazing thing it was, in a pre-internet world, to be able to get information on the high seas, thousands of miles from land.

Farewell, Radio Australia and thanks for the trip down Memory Lane.


And thank you, John, for sharing your memories with us!
