The broadcasting service was officially inaugurated by broadcasting the speech made by the then Governor Sir Hugh Clifford addressing the general public from his office situated at Fort.

On 05th October 1945 the Ceylon Broadcasting service was instituted as a separate government Department while arrangements were made to construct a new building for the Service at the Torrington Square.

Bangladesh Betar - The Story of Glory

These days, when information technology and the internet are not far from our grasp, on hearing the name "Bangladesh Betar (Betar meaning radio in Bangla)", one might ask, "Who would listen to Bangladesh Betar today?" You may contemplate that their programmes are not interesting enough for this day and age, or even term them "monotonous." However, to your surprise, there are still a large number of people who feel nostalgic on just hearing the name of the shows that used to air in Bangladesh Betar.

AirSpy HF+ specs unveiled...

This will be a game-changer from Youssef (Airspy, SDR#), outstanding performance at a low price. SDR Console support – of course.

Preliminary specs:

RX range: 0 .. 30 MHz (HF) and 60 - 270 MHz (+)
Architecture: Hybrid (Direct conversion + DDC) using 2 x sigma delta ADC's @ 36 MSPS
Front end: Tracking Filters (all bands), High Dynamic Range LNA's and Mixers
AGC: Smart AGC controlled by the DSP
DSP: CIC, CFIR and a final (programmable) channel FIR - 18bit resolution
Final bandwidth/resolution after DDC: 18bit @ 600kHz - Scaled and streamed as 16bit
Image rejection: better than 120dBc
Blocking DR: 108 dB
Separate HF and VHF RF inputs - with option to use one multiplexed input if desired
USB 2.0 with Plug and play - No drivers needed
The RF section resides inside a metal shield
Aluminium enclosure about 60 x 100 x 15 mm^3

Basically, this addresses the lack of affordable and good performing receivers for HF and VHF.

Target price  < $200

Simon Brown, G4ELI

(Via list)

2 x 36MSPS IQ (equivalent to direct sampling at 72 MSPS) gives roughly 36 MHz of bandwidth, however the ADC's used are sigma-delta with intrinsic anti-alias filtering.

We start with 16bit IQ at 36MSPS then it is frequency translated and decimated to 744.192 ksps 18bit IQ with a bit more than 600 kHz bandwidth plus the digital filter roll off. Given the very nature of sigma delta ADC's, the pressure on the front-end filtering is relaxed and the tracking filters are even more effective.

The image rejection is performed using a newly designed algorithm that matches the performance of the hardware.

All the decimation number crunching happens in the device like in most high end DDC receivers, so we only need a small USB throughput in the end (~23Mbps), and the CPU usage in the PC is very low.

Performance wise, the result is comparable to things like Perseus, RFSPACE, Elad, etc. but with a more modern full CMOS sensitive front end and at a fraction of the price.

Hopefully, this will redefine the word "performance" for most Hams and SWLs ;-)

Days of the radio

Nostalgia' is probably the first word we associate with 'radio'. A 5-minute break from the hassles of Friday traffic, a request show and a song for your lover, or that catchy jingle simply refusing to erase itself from memory – these are what make radio, RADIO!

So tune in and stay tuned...the transmission begins now...

It was to honour this radio that the United Nations proclaimed 13 February as World Radio Day in 2011, with the vision of celebrating how it helps shape our lives.

Voice of America Celebrates 75 Years

WASHINGTON D.C., February 1, 2017 -- Today the Voice of America (VOA) celebrates 75 years on the air.  From its first 15-minute radio broadcast in German in 1942, VOA has grown into a multimedia international broadcast service providing programming and content in 47 languages on multiple platforms, including radio, television, and mobile.

On that first broadcast, announcer William Harlan Hale set the standard for all future VOA programs when he told his audience: "We bring you Voices from America. Today, and daily from now on, we shall speak to you about America and the war. The news may be good for us. The news may be bad. But we shall tell you the truth."

Today those words carry the weight of the VOA Charter that requires VOA, by law, to "serve as a consistently reliable and authoritative source of news." What's more, VOA news must "be accurate, objective, and comprehensive."

"It's been 75 years since we first began broadcasting objective news and information around the world," said VOA Director Amanda Bennett. "And now, I think what we do here is more important than ever."

Over the years, VOA correspondents and freelance reporters in many parts of the world have been on the scene to cover major world events. In 1989, VOA East European correspondent Jolyon Naegele reported on demonstrations in Czechoslovakia and the fall of the communist government. That same year on the other side of the world, VOA increased programming and added staff to its Beijing bureau, to cover the demonstrations in Tiananmen Square. VOA Beijing Bureau Chief Al Pessin was expelled from China for his reporting.

Today VOA broadcasters use television and radio studios at its headquarters in Washington, D.C. to broadcast news and other programming through 2,500 television and radio affiliate stations around the world. At the same time, they provide content for mobile devices and interact with their audiences through social media. In 2016, the Voice of America's weekly audience across all platforms averaged more than 236 million people worldwide. Click here for more information on Voice of America's 75 years of history and here for a short video on its history.

VOA reaches a global weekly audience of more than 236 million people in over 40 languages. VOA programs are delivered on satellite, cable, shortwave, FM, medium wave, streaming audio and video on more than 2,500 media outlets worldwide. It is funded by the U.S. Congress through the Broadcasting Board of Governors.
