RTÉ longwave set to continue “until at least 2019”

(Source: The Irish Post)

RTÉ are set to continue transmitting their longwave 252 service until at least 2019 after positive talks took place at a consultative meeting in London.

The news follows a statement issued by RTÉ back in October in which the state broadcaster announced its “intention to close the service in 2017.”

RTÉ said at the time that they were exploring the possibility of using ‘alternative technologies’ to help maintain links with its audiences in Britain beyond the service’s closure.

But longwave is now set to continue transmitting through 2017 and 2018 after a week which saw calls for the service’s retention heard in the Seanad.

Last week, independent Senator Billy Lawless sought government assurances that the Irish in Britain would not lose access to longwave 252.

Senator Lawless urged Minister of State for the Diaspora Joe McHugh to “implore RTÉ management to reconsider this ageist and discriminatory cut” to its longwave 252 service.[…]

Urban DXing: testing the Bonito Boni whip against a 30 metre longwire & the Wellbrook ALA15030

Hi there, if like me, you live in an urban environment, chances are QRM is having a negative impact on the quality of the signals you’re receiving at home. The presence of electrical noise makes antenna choice very important, particuarly if you’re planning to spend more than a few £££s on something more sophisticated than a length of wire. Recently I was considering the the purchase of a second compact antenna, for use at home in my shack and out and about on DXpeditions. I already had the excellent Wellbrook ALA1530 H field antenna, but at more than £250, it’s very costly and thus it seemed rather extravagent to buy a second one, if I could find something with similar performance for less expense. Space is at a premium at home and of course I take much of my equipment out on DXpeditions, so the Bonito Boni whip active antenna appeared to be an ideal choice. A wideband active antenna (from 20 kHz to 300 MHz) operating from 12 to 15V DC, with a very compact form-factor definitely ticked all the boxes. Furthermore, with reasonable second and third order intercept points of +55 and +32.5 dBm respectively, the Boni whip, on paper at least, looked like a pretty good buy at around £100.

 

Now, clearly, an E field antenna such as the Boni whip is not going to match the SNR provided by the H field Wellbrook ALA1530 in a noisy, urban environment. I have uploaded a few reception videos to my YouTube channel to demonstrate this, making a direct comparison of the two. However, what about the performance of the whip versus a simple longwire in an urban environment? Is there a delta in performance? The value proposition of the whip is primarliy in it’s performance, coupled with portability I suppose, but that must be considered a secondary requirement. The whip might be 10 or 15 times more expensive than a reel of cheap equipment wire, but will the reception justify the cost delta?!

Text links follow directly below, with embedded videos thereafter; you will find 3 reception videos comparing the whip and a 30 metre longwire, on shortwave and one each for LW and MW. At the end of each video there’s a section with the Wellbrook loop, just to calibrate where the longwire and whip are in terms of a much more effective H field antenna. The result? Well, there’s not much to separate the longwire and Boni whip, except on LW, where the whip prevails. A friend told me recently, if reception is rubbish at home under a blanket of QRM, don’t blame the antenna, the noise is the real problem. He was right. So, the next tests are to be undertaken out in the field, where the whip has a real chance to shine. I’m rooting for it because to have an antenna that performs as well as, or close to my loop out in the woods, yet can be packed away into a small case would be brilliant. Thanks for reading/watching/listening.

WI2XLQ (formerly WG2XFQ): Brian Justin’s annual longwave broadcast Dec 24-25

Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932)

Now an annual Christmas tradition, Brian Justin (WA1ZMS) will put his longwave experimental station WI2XLQ on the air to commemorate the 110th anniversary of Reginald Fessenden’s first audio transmission.

WI2XLQ will broadcast under its new callsign (formerly WG2XFQ) on 486 kHz from Forest, Virginia, beginning on December 24 at 0001 UTC. WI2XLQ will remain on the air for 48 hours.

Listener reports may be sent to Brian Justin, WA1ZMS, at his QRZ.com address.

If you would like more information about Brian Justin and WI2XLQ, check out our interview with him in 2013. Indeed, I successfully heard the 2013 WG2XFG broadcast and posted this audio clip on the Shortwave Radio Audio Archive.

Additionally, SWLing Post reader, George Stein has a very personal connection with radio pioneer, Reginald Fessenden: click here to read his story.

162 kHz longwave: CSA France seeks expressions of interest for broadcast license

French 162 kHz Broadcast Licence

The French Superior Council of Audiovisual (Content), CSA, is calling for expressions of interest in broadcasting on 162 kHz

They say: In accordance with the provisions of Article 26 of the amended Freedom of Communication Act of September 30, 1986 and at the request of the Government, the CSA decided to withdraw from Radio France the use of the 162 kHz frequency for broadcasting of France Inter.

In order to determine whether the Commission should initiate the procedures necessary to appeal the 162 kHz frequency, it decided to issue a call for expressions of interest for the broadcast of a radio service on the 162 kHz frequency.

Responses are expected no later than January 16, 2017.
