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.[…]

The Eton Satellit: my thoughts after 3 weeks of DXing and some recent catches…

Hi there, it’s been about three weeks now since I started DXing with the Eton Satellit and I thought it time to post an updated review, based on my experiences thus far, along with some recent catches. Noting that other radio hobbyists with a strong presence online have been posting neutral to negative reviews on this receiver, I would just like to point out, perhaps rather obviously, that no receiver is perfect and just as importantly, the criteria on which a portable radio is judged will be different from user to user, based on their listening habits. I am almost exclusively engaged in DXing with the Satellit, whilst others will be listening on the broadcast bands on a more casual basis. I know that for some, the ultimate quality and finish of a product is as important as performance and they would make their physical assessment in a very detailed manner. I on the other hand focus mainly on performance and as regards quality, I’m reasonably satisfied if it doesn’t fall apart in my hands, straight out of the box! That actually happened – and it’s sort of where I draw the line 🙂 I guess the point is, I try to respect everyone’s opinion, irrespective as to whether we are in agreement or not and I believe that’s healthy for the future of our hobby.

Ok, back to the Satellit. Firstly, I am able to confirm that in terms of ultimate sensitivity, this portable is very close to my Sony ICF-2001D – one of the most highly regarded portables ever made. The delta in performance between the two is most perceptible on the weakest of fading signals that intermittently deliver audio with the Sony, but can’t be heard on the Eton. On stronger signals, my experience is that either radio might provide the strongest and or highest fidelity audio. I have a series of comparison videos already in the can, which will be uploaded to the Oxford Shortwave Log YouTube channel soon.

In terms of selectivity, the digital bandwidth filters work very well, although I note that even on the narrowest setting (2 kHz) when operating in a crowded band, adjacent channel QRM can occasionally still sound quite pronounced, as compared to my Sony ICF-SW55 or ICF-2001D receivers. As regards synchronous detection, this is more of a hit-and-miss affair. Subscribers to my channel might notice that in nearly all of my reception videos featuring the Eton Satellit, I have not engaged the SYNC. That isn’t to say it doesn’t work, however, even with selectable sidebands, the SYNC mode often appears to increase the overall signal amplitude and noise floor, without positively influencing the SNR. However, it’s interesting to note that signals on the Satellit in AM mode often almost match the ICF-2001D in SYNC mode, in terms of overall SNR. More on that to come.

There are a number of ways to tune the radio; manually using the tuning knob (and this has a decent feel/ resistance to it), direct frequency input which requires pressing the ‘AM’ button to engage, automatic search and access to 700 memory locations, via 100 screen pages. In the real world – and by that I mean ‘my world’ which is most often in the middle of a field, or the woods, all of the above tuning options are as ergonomic as most of my other portables. With regard to SSB reception, there are fast, slow and fine tuning options with a maximum resolution of 10 Hz and this works very well to reproduce natural sounding speech in LSB and USB modes. The tuning speed/fine options are engaged by pressing the tuning knob inwards towards the set – quite a neat idea. With SSB and SYNC there’s always a little pause whilst the electronics engage – a set of chevrons appear on the screen to indicate the receiver is actually doing something. It’s similar to the Sony ICF-SW77 where you effectively toggle between SYNC USB and LSB and wait for lock. Not an issue for me, but it might annoy some, particularly those who have experience with the ICF-2001D, where SYNC engagement is instantaneous, if the signal is of sufficient strength. A small point, but worth making.

 

So, overall, a brilliant little radio that in my opinion is completely worthy of the ‘Satellit’ branding, at least in terms of ultimate performance. As I mentioned previously, one of the most experienced DXers I know, with more than 3 decades of listening to the HF bands and an owner of a number of vintage Satellit receivers noted that the Eton Satellit outperformed them – and by some margin. To further demonstrate this, I have included links to recent reception videos. In particular, I copied three of the regional AIR stations with signal strength and clarity that had never previously been obtained. I also copied HM01, the Cuban Numbers Station for the first time on the 11 metre broadcast band, Sudan and Guinea on the 31 metre broadcast band (a whopping signal from Guinea) and Polski Radio 1 on longwave. I hope you find them interesting. Since featuring the Satellit on my channel, one of two of my subscribers have purchased this radio and thus far have been very happy indeed with it’s performance.

Ultimately, I have to strongly recommend this portable to anyone interested in DXing and in particular those that embark on DXpeditions. I just hope that should you decide to buy one, you receive an example that performs was well as mine. Embedded reception videos and text links follow below, In the mean time and until my next post, I wish you all great DX!

Kris also forced the Shipping Forecast to repeat a broadcast

Many thanks to SWLing Post contributor Kris Partridge (G8AUU) who shares the following comment in reply to our post about Dave’s experience forcing the Shipping Forecast to repeat a broadcast:

Hi Dave, G4OYX, et al

Not the only time the Shipping Forecast has had to be repeated for ‘Operational Error’

I hold my hand up for having had a broadcast repeated.

One morning, whilst still under the duvet, I found myself still listening to the overnight simulcast of BBC World Service on the BBC Radio 4 outlets. The simulcast of World Service is scheduled from 0100 local, just after the 0048 Shipping Forecast, till 0520 when it is followed by the Shipping Forecast. That wasn’t right, it now being around 0540. A quick check on the LF output, I was listening on my VHF-FM alarm radio, again it’s World Service. Something not quite right..!

Having the internal extension number of LCR (London Control Room) at BH (Broadcasting House) I made a quick call. A voice I recognised answered and after a short conversation was assured it would be remedied.

It was a few minutes later the Shipping Forecast was going out on 198 kHz and other R4 frequencies, followed by a short apology ” for technical reasons”.

A later phone call and heard, the overnight software update had managed to have done an update where it shouldn’t have.! I think a few red faces all round in the IT department.

So Dave the transmitters were OK it was the feed this time.

73 de Kris (G8AUU)

Thank you so much for sharing your story, Kris!

I mean, what are the odds that two people in our Post community have forced a re-broadcast of the Shipping Forecast??? Anyone else want to make a confession? 🙂

Dave once forced the Shipping Forecast to repeat a broadcast

Droitwich transmitting station (Source: Wikipedia)

Our post yesterday regarding the Shipping Forecast reminded me of a story SWLing Post contributor, Dave Porter (G4OYX) once shared. Dave writes:

I worked at the Droitwich Transmitting Station through 1972-1974, the home of the BBC UK Long Wave 1500 m/200 kHz service as it was then.

In the summer of 1973 I was junior member of the engineering team, a 21 year-old Technical Assistant, and manned the control room for the four services from the site, Radio One, 1214 kHz, Radio Two, 200 kHz and Radio Four, 1052 kHz.

It was customary to check the two 200 kW transmitters, T7A and T7B for power balance prior to the Shipping Forecast and I duly went out in the transmitter hall just before the start at 1355.

I noted one was a little down and the other a little high so I pressed what I thought was the raise / lower buttons on the control desk. Unfortunately I had pressed the main on/off buttons instead.

The pair of transmitters came instantly off the air. I could hear on the audio monitoring the announcer starting the broadcast… it takes a while to reinstate the mercury arc rectifiers as the regulators had to run all the way down to zero and then back up to 14 kV.

By the time I had got it back on the air he was just finishing so we had to contact London and arrange a repeat after the 1400 news bulletin… Ooops!

I was much more careful after that when adjusting the transmitters.

The Senior Maintenance Engineer was not best pleased, as he had to write up the shutdown report for London citing “Operational Error” as the cause.

Happy Days…

Dave G4OYX.

That’s a brilliant story, Dave! Thank you so much for sharing. Oh…I’m sure it’s a lot easier to laugh about it now than it was when it happened! 🙂

The Eton Satellit: a poignant recording of ABC Northern Territories & further DX…

Hi there, I’ve just returned from a business trip to Genoa, Italy and took the Eton Satellit with me. Now, I’m sure many of you know from your own experiences that DXing from a noisy hotel room can be just about impossible – and so it was in the main. I did however manage to copy a very nice signal from BBC Radio 5 Live on 693 kHz medium wave and Chaîne 3, from Tipaza, Algeria on 252 kHz – the latter is a much more difficult catch back in the UK. Reception videos for these two signals also follow below and I have to say that given the very noisy environment, this was a pleasing result using the Eton’s internal ferrite antenna. Prior to my trip this week, I recorded a really nice signal from Radio Nacional Brasilia on 11780 kHz and the best signal from North Korea (Voice of Korea KCBS) I’ve ever copied on the 41 metre broadcast band. Both are testament to the Eton Satellit’s performance as an excellent portable reciever per se and it’s hard-core DXing capabilities. Finally, what now feels a very poignant recording, I managed to catch – ABC Northern Territories on 2325, 2485 and 4835 kHz during the same session and on one reception video. Embedded videos and text links to these videos on Oxford Shortwave Log follow below, along with a brief video review of the main functions and features of the Satellit.

With regard to the closure of ABC on shortwave, my full support goes out Senator Nick Xeonophon and his quest to introduce new legislation to force the ABC to reinstate their shortwave transmissions. There, I’ve said it and that’s enough politics for now lol. In the meantime, my plans to test the Eton Satellit against more established DXing portables remain in place and work commitments allowing, this should happen soon. Thanks for reading/watching/listening and I wish you all great DX!

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.
