AIR has acquired 37 DRM transmitters, in talks to get cheaper radio sets

NEW DELHI: All India Radio (AIR) has introduced digital radio technology in the AIR Network by installing new state of the art Digital Radio Mondiale (DRM) Technology transmitters by replacing old outlived 37 Medium Wave/ Short Wave transmitters.

Minister of State for Information and Broadcasting Rajyavardhan Rathore told Parliament however that the provisions contained in Policy Guidelines on expansion of FM Radio broadcasting services through private agencies (Phase-III) do not provide for private FM broadcasters to adopt digital radio technology.

He said Digital Radio allows significant improvements in service reliability, audio quality, more radio services and higher efficiency.

The new AIR transmitters include 35 new state of art technology Medium Wave (MW)/ DRM transmitters as a replacement of old technology valve based MW transmitters. Additionally, two new state of the art technology Short Wave (SW) DRM transmitters have been approved for installation as a replacement of old SW transmitters.[…]

The brilliant little Tecsun PL-310ET: serious DXing on a budget – part 2

Hi there, here is part two of my original post containing various reception videos for the amazing Tecsun PL-310ET pocket shortwave receiver. I continue to be amazed at the sensitivity and selectivity of this rather modest and diminutive receiver, particularly at it’s price-point of around £40 in the UK and less elsewhere! Here is the second half of the reception videos, with some nice signals from Brazil, Guinea, Ethiopia, Swaziland and India. You might notice that some of these catches involve the use of a 240 metre (approx.) length of barbed wire fence! I’m not sure how beneficial the electrical properties of the fence were, probably somewhere between not great and not good lol, but some pretty decent DX was had with the PL-310ET attached to it via the external antenna socket and a crocodile clip!

The barbed wire fence extends almost to the treeline on the horizon; about 240 metres

I hope you enjoy this set of reception videos, they certainly help to demonstrate the great performance of the PL-310ET and in addition of course, it’s ability to handle large antennas quite well. Embedded videos and text links follow below. Lastly, there are now approaching 1,200 reception videos on my YouTube channel Oxford Shortwave Log and I would like to take this additional opportunity to thank everyone for their support, friendship and advice.  In the meantime, I wish you all a very Merry Christmas, a Happy New Year and excellent DX!

Many thanks to SWLing Post reader, Mike, who shares a link to the following interview with Fayyaz Sheheryar, Director General of All India Radio. I’ve pasted a couple of Sheheryar’s responses below–click here to read the full interview.

But there had been some talk in the government at one time to disband short wave broadcasts?

Yes, but we had opposed this and it is agreed by all that short wave will stay.

What are the future plans for popularizing programming and strengthening internal functioning?

AIR has embarked on a major plan to start a Content Delivery Network (CDN) which will be ready within the next two to three months. It will help keep track of number of listeners, and also prevent ‘stream theft’.

There will be greater live streaming of channels on the internet complementing Short wave on air.org.in, and Mobile Apps will be launched for more channels. It will also be possible to give audio on demand and the internet will store programmes of up to seven days for this purpose. The App will be monetized, and there will be an alert which gives information about listeners, and messages and advice about programmes on the Apps.

India’s terrestrial transmission today was even larger than China.

Thanks again, Mike, for the tip!

AIR to recruit Balochi speakers with money saved from shortwave broadcasts

Many thanks to SWLing Post contributor, Mike Barraclough, who shares the following link from The Sunday Guardian Live via Facebook:

At present, AIR has only two Balochi speaking people who have been helping with the daily one-hour programme transmitted to Balochistan. A senior AIR official, on the condition of anonymity, said, “There has always been a dearth of Balochi speaking people here. Even before Balochistan got attention in mainstream Indian media, we had been working to improve our Balochi show. For years, we had been writing to the Ministry of Home Affairs and Ministry of External Affairs to help us get some talented people from Balochistan who can work with us on improving content in our Balochi shows. ”

[…]”Since we are gradually switching from short-wave to a web-based service now, all our overseas shows in various languages are already starting to get more human resource. We have more funds to invest on quality of our programmes. Earlier, such funds were largely spent on the maintenance of short-wave machinery.”[…]

Tropical Band DXing at home with Elad FDM DUO and Wellbrook ALA1530 active loop

2-jungleRecently I have spent a little more time listening out for Tropical Band stations from my shack in Oxford UK, attempting to emulate some of the very nice signals I have previously recorded out on DX’peditions. The obvious problems with this (and they are numerous) include the relatively weak signal strength of many tropical band stations, the ubiquitous blanket of QRM, resulting in generally poor SNR, lack of space for a large antenna……need I go on?! Fortunately, the Elad FDM DUO has proven to be a very senstive and selective receiver, capable of, at times, incredible SNR, coupled with almost limitless signal conditioning options and SSB, SYNC, ECSS etc. Throw the Wellbrook ALA1530 active loop into the mix (not literally!) and you have a very powerful Tropical Band receive set-up. The Wellbrook is able to null most (although not all) QRM in my shack and that really can make the difference between simply observing a carrier and actually hearing audio. Clearly one cannot expect to hear DX at home under heavy QRM as well as you might outdoors, however, the following stations were logged in the past month or so, with respectable signals, with the ALA1530 indoors:
