The Sri Lanka Broadcasting Service commenced on 22nd July 1924 as a test transmission. It was launched officially on 16th December 1925.The test transmission was initiated by broadcasting a speech made by the then Governor Sir William Henry Manning, addressing the Lanka Electrical Engineers' annual meeting. 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.

The station was known by many names from time to time such as " Wireless Broadcasting" and "Colombo Broadcasting". It functioned under the purview of the Postal Department until 30th September 1949.

From 5th October 1979,it was made independent and came to be known as Radio Ceylon.

On 5th January 1967 the Department of Broadcasting was converted to a government Corporation by way of Act No.37 of 1966.

The Corporation was inaugurated by the Hon. Prime Minister and came to be known as the Ceylon Broadcasting Corporation.

On 22nd May 1972 with the enactment of the first Republican Constitution, the Ceylon Broadcasting Corporation was renamed as the Sri Lanka Broadcasting Corporation.

On 5th January 2017 the SLBC celebrates its Golden Jubilee by relocating its core functional Divisions in a new Administrative Building to be declared open by H.E. President Maithreepala Sirisena and the Hon. Prime Minister RanilWickramasinghe. A major Project aiming to renovate SLBC's studio complex will also reach completion by the same date.

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...

"Radio programmes can be aired to listeners at Goa's bus stands, markets, parks and beaches. Educational institutions and NGOs can use radio to highlight social issues," Roland Martins, coordinator of Friday Balcao, the fortnightly discussion event said.

Celebrating World Radio Day 2017 -by F.Sheheryar, DG,AIR

When Neil Diamond crooned "reaching out, touching me, touching you" in that iconic song Sweet Caroline, he could as well be singing about radio. Radio, which reaches out across seemingly insurmountable geographical divides, touches countless lives and yet remains in the background. 

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.
