US listener: “Personal connection makes me want to listen to VOV”

(VOVWORLD) – The Voice of Vietnam (VOV) turns 72 this Thursday. Over the past 7 decades, VOV has served as a bridge linking Vietnam with people all around the world. Paul Walker, an American radio presenter and a loyal listener of VOV, says it is the personal connection that makes him want to listen to VOV and learn about Vietnam.

After a 6-hour drive from Washington we reached a small town in Pennsylvania near the border with Canada. It was a peaceful, quiet place with houses dating back more than 100 years. Paul Walker, a young radio presenter, met us in front of his house with his radio gears already set up.

With a small table and chair, 2 antennas, an analogue receiver, a tuner, and a digital recorder, Paul finds it interesting to listen to foreign radio programs. Paul said he picked up an obsession with radio when he was a kid and this passion has grown year by year. Now he is doing radio for a living.

“I started listening to the radio as a real young kid. In fact listening to the radio is what made me want to get into radio. I listened to that growing up and now I get paid to play music. I wanted to do it as a kid and that’s what I do now for a living. I’m actually a radio presenter here in the United States, play music on the radio, put together commercials, manage FB pages for radio stations and general stuff like that,” Paul said.

Paul started to listen to VOV in the summer of 2015 and since then VOV has become an indispensable part of his listening schedule.

Paul said he listens and sends in reception reports to VOV quite often with every detail he recorded with his radio equipment: “I like the music, especially when they play the older music. I also like to listen to news because I like the different perspectives, different opinion on it because other countries see things differently than we do and I like to hear that. I like the Letterbox program that is one of my favorites, I like to hear how other listeners tune into VOV and what they like about it and it seems like a fairly large amount of people like the music so I know there’re many of us out there. VOV’s English announcers are very friendly”[…]

North American and European medium wave signals into Oxford, UK

Hi there, I’ve been rather preoccupied of late, initially with the brilliant Tecsun PL-310ET and latterly with the even more brilliant Eton Satellit. However, in the background (as always), I’ve been trying to catch transatlantic medium wave DX. My listening schedule is broadly based on shortwave DXing during daylight hours – when I’m not at work of course, typically a Friday afternoon or at weekends – and always with a portable. Evenings usually start off with a tune around the tropical bands, followed by setting up the Elad FDM DUO to run some medium wave spectrum recordings overnight. In the past few days though, my daylight DXing has been bolstered by my NooElec RTL-SDR and ‘Ham it up’ upconverter. I bought the device over a year ago and after some initial exceitement, it quickly became quite obvious that I needed a reciever with a bit more ‘oomph’! However, it’s actually proving very useful to view signals on a  spectrum, even when I’m conducting most or all of my listening on a different (i.e. higher performing) receiver. Ultimately, the RTL-SDR is always going to be a compromise, with relatively limited sensitivity, but because by it’s very nature it has excellent selectivity, overall it’s a reasonable performer. My particular RTL-SDR performs quite well if a decent antenna is employed with it, such as a longwire or the Wellbrook ALA1530 active loop.

Anyway, back to the medium wave DX. In the past month or two, I’ve copied a number of stations from North America, with really nice signals, including WRCR Rampano – New York, WFED Federal News Radio – Washington DC, WENE – Endicott and WUNR – Brookline from Newton, Mass. I’ve also recorded a lovely interval signal from RAI Radio 1, Milano and further European signals from Magyar Radio, Budapest and Radio Slovenija 1, from Ljubljana. During the past 18 months or so of DXing, I have been mostly ignoring signals coming into Oxford from the continent. However, that changed a little after I stumbled across the RAI Radio 1 interval signal, which complete with the rather rousing Italian National Anthem, inspired me to dig out some more European DX. I’m actually finding European DX quite rewarding, particularly because it feels new again – not surprising since I haven’t listened to Europeans on medium wave for any length of time since the 1980s. I hope you enjoy the reception videos – embedded video and text links follow below and I wish you all the very best DX.

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!

Dean: An intrepid young DXer!

Dean’s trusty Tecsun PL-660

UPDATE (28 October 2017): We’ve updated links to Dean’s website to reflect his new URL.

A few weeks ago, I received a message from SWLing Post reader, Dean Denton, who lives in Hull, UK. Dean is not your typical contemporary shortwave listener–he’s twelve years old and has been DXing since the age of eight! While, decades ago, that used to be the norm–indeed, I started SWLing at eight–Dean is bucking the trend in 2017.

Dean’s listening post consists of a few receivers:  the Tecsun PL-660, a Tesco RAD 108, a Uniden UBC360CLT and a Hitachi TRK P65E. Dean also spends a great deal of time on the excellent University of Twente WebSDR.

Dean noted in a recent message:

“I typically love a lot of broadcasters, but generally China Radio International, Radio Romania International, BBC, Voice of America plus many more. I like talk and news on shortwave radio as it gives an insight of a typical country’s actions.

I also love music on shortwave due to Amplitude Modulation and its characteristics. Not to mention Pirate Radio, HAM Radio, Numbers Stations and anything else.”

Dean, you’re a kindred spirit indeed–to me, there’s nothing like the sound of music via the “sonic texture” of shortwave radio.

Not only is Dean a radio enthusiast, but he also started a website and is building a library of videos on his YouTube channel. Indeed, most recently, he’s been experimented with Narrow Band TV on his YouTube channel.

While looking through his channel, I found this screencast and recording he made as France Inter shut down their 162 kHz longwave service as 2016 came to a close:

Dean, keep us informed about your DXing adventures and don’t hesitate to ask questions!

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.
