Thanks for the tip, Ron! Based on the photos, the construction looks to be of very good quality. There are so few VLF converters on the market–please share your review when you’ve had a chance to evaluate it!

RTÉ longwave 252: maintenance shutdown June 27 – July 8, 2017

Many thanks to SWLing Post contributor, James Leary, who shares the following news and audio clip from RTÉ:

Hi Thomas, I heard this announcement the other day about RTE 252 and thought it might be of interest for your site. I think it’s also going to shut down permanently in 2019.

Received on a Tecsun PL-390 in NW UK.

Thanks for the news and recording, James!

You’re correct: according to an article from Radio Today, RTÉ has agreed to continue its longwave 252 service until the end of June 2019.

Impressive that RTÉ’s longwave transmission equipment has been in continuous operation for over 27 years! I’m not surprised the antenna needs maintenance.

The Bonito Boni whip: proving to be excellent portable antenna for DXing

Hi there, if you’re a subscriber to the Oxford Shortwave Log YouTube channel, you will be aware that I have been using a Wellbrook ALA1530 H field antenna, for 15 months or so, with (at times) excellent results. A while back I was on the lookout for a second antenna, however at more than £250, I couldn’t justify purchasing a second Wellbrook. Ultimately I splashed out on the Bonito Boni whip E-field wideband active antenna (20 kHz to 300 MHz) and with a very compact form-factor suitable for DXpeditions/portable operation in general, the Boni whip 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.

 

Initial testing at home confirmed, perhaps not surprisingly that the Boni whip could not match the SNR provided by the Wellbrook ALA1530 in a noisy, urban environment. However, less predictably, the Boni whip has proven to be a truly excellent antenna away from the ubiquitous blanket of ‘electrosmog’ at my QTH. Furthermore, it really is so compact, I simply leave it in the car in a small flight case, with a portable and connectors etc. for ad-hoc listening sessions. Since returning from my most recent trip to Brazil, I have had a chance to review my most recent catches with the Boni whip, some of which are realy pleasing and most definitely underline the excellent performance of this diminutive antenna. In particular, signals from Radio RB2  on 11935 kHz and Radio Aparecida on 11855 kHz, both low power Brazilian stations, are testament to how sensitive the Boni whip is in an electrically quiet environment. Check out also the quality of longwave signals from Poland and the  Czech Republic – simply amazing for such a physically short antenna. Finally, there’s a personal first from Lusaka, Zambia, Voice of Hope Africa on 13680 kHz. All the more rewarding that this was actually copied in my work office!

I hope you found this article interesting. There are embedded reception videos below and text links for all, which will take you directly to the relevant video on the Oxford Shortwave Log YouTube channel. Thank you for reading/watching/listening and I wish you all excellent DX!

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.[…]
