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!

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

The Eton Satellit: a short history & first impressions as a DX workhorse

9 Replies

Hi there, I’m sure some of you will read the title of this post and conclude ‘that’s exactly that the Eton Satellit could never be’. I was of the same opinion, having read many reviews online suggesting this little radio on shortwave at least was essentially a bit ‘duff’ as we say in the UK. The fundamental flaws identified when it was first released included, but were not limited to – a general lack of sensitivity, poor AM SYNC stability and poor AM SYNC audio, poor filtering, particularly in SSB mode, muting whilst tuning, poor display visibility in sunlight, poor AGC timing…the list goes on.

On MW and FM there was a general consensus that this little radio performed very well, but with all the other flaws highlighted here, it certainly did not represent good value for money. A number of reviewers concluded that the Eton was an insult to the ‘Satellit’ brand. Oh dear, yet another shot in the foot for Eton then. User perception was confirmed when I posted my first reception video using this radio – a number of my Oxford Shortwave Log subscribers got in touch to say they were essentially scared off buying this radio at the time and that this was of course driven by the negative reviews that proliferated the internet.

Since the original launch, however, it would appear that firmware updates have improved this receiver immesurably, although I am quite certain this news hasn’t really filtered out into the market because there still appears to be a consensus that the newest Satellit is ‘not worthy’ so-to-speak. So, how did I come to buy a Satellit, a decision that could very well be perceived as risky to say the least, even foolhardy?! Well, one of my DXing fellows on YouTube (check out his YouTube channel – it’s full of amazing DX) posted a video of his recently purchased Satellit in a number of tests against the (largely) brilliant Tecsun PL-880. The Satellit equalled or bettered the PL-880 on MW and SW. I was very surprised at this outcome, for the same reasons as everyone else – it wasn’t supposed to be that good.

Even though the poster himself suggested the Eton might not be classified as a classic Satellit, it’s interesting to note that another DXer with three decades of experience and someone who’s owned the Satellit 400, 500 and 700 models concluded the opposite and that for various reasons, the newest Satellit is a far better performer with weak DX than those vintage receivers ever were. In his experience, the classic Satellit receivers always delivered excellent audio and thus were brilliant for listening to international broadcasters. However, for weak DX the Satellit 500 didn’t perform as well as the budget Sangean ATS-803A and the ICF-2001D wiped the floor with the 700. So, is the Eton worthy of the Satellit branding? Perhaps the problem is it’s just so small – I mean compared to the Satellit 800….you could confuse the Eton to be it’s remote control – if it had one! It is diminutive and I’ve purposely taken a picture of it with my calculator to demonstrate this. It’s actually not much bigger than the Tecsun PL-310ET, so in terms of form-factor, definitely a departure from Satellits of the past.

What about performance? I tested the Eton at the woods I use for DXing, with a 50 metre longwire. In the space of a couple of hours, I’d recorded ABC Northern Territories on 2325, 2485 and 4835 kHz, Pyongyang BS, North Korea on 3320 kHz, Angola on 4950 kHz, Guinea on 9650 kHz and a weak signal from the Solomon Islands on 5020 kHz. The signals from ABC on 2485 kHz, Angola and Guinea were stronger and clearer than I’d ever heard previously. Pyongyang on 3320 kHz and the Solomon Islands were personal firsts.

The Eton performed way beyond my expectations and I hope this post will go some way to restoring the repuation of this brilliant little radio, which in my opinion fully deserves to be called a Satellit. More testing is necssary, including direct comparisons with other receivers – all of that to come in due course. Text links and embedded reception videos follow. Thanks for reading/watching/listening and I wish you all great DX!

The diminutive but brilliant Sony ICF-SW100: a few autumn/winter DX catches

10 Replies

Hi there, I posted an article on this brilliant little radio a few months ago because it had demonstrated a level of performance way beyond my expectations. Notwithstanding it’s incredibly small size the DX results I obtained with it were beyond my ICF-SW55 and up there with the iconic ICF-2001D. Armed with synchronous detection, selectable side bands, SSB, CW and sensitivity seemingly boyond it’s tiny form factor I can’t recommend this radio highly enough.

Originally introduced into the market in 1993 and discontinued in 2005, the ICF-SW100 won’t ever be repeated – a point I made in my original post, but of course they are available on eBay and prices remain robust for what is now essentially a vintage receiver. Unfortunately, I don’t get to use my ICF-SW100 very much as I have various other receivers and have been involved in antenna building/testing and MW DX for the past few months. However, on the couple of occasions when I have taken the Sony on a mini DXpedition, it’s resulted in some fine DX. As demonstrated in the examples below, Mali, Guinea, Alaska and Japan are amongst the more difficult signals to copy in Europe and yet the ICF-SW100 delivered them!

DXpedition antenna testing: the Bonito Boni whip and a 240 metre barbed wire fence

2 Replies

Hi there, a few days ago I posted some reception videos comparing the performance of the Boni whip with a 30 metre longwire antenna at home, with a further check against the performance of the H field Wellbrook ALA1530 active loop. The conclusion of those tests was essentially confirmation that E field antennas don’t usually perform very well under a blanket of ‘electrosmog’ and that only on Longwave, did the Boni whip prevailed over the longwire; otherwise there was no usable difference in performance between the two.

Sony ICF-SW55 receiver ‘Quiet’ location for Boni whip test

This prompted a number of my subscribers to ask when I would be taking the Boni whip on a DXpedition for an outdoor test against the Wellbrook and either a substantial longwire, or the 200 metre Beverage. Time is limited right now for a full test, however, I managed to throw together a kit of parts necessary to run a quick set of comparison tests with the whip, against the barbed wire fence I use for ad hoc DXing when out walking the dog! Over a period of an hour or so, I managed to copy a few stations on 31 and 49 metres and thus recorded signals using the Sony ICF-SW55 receiver with the Boni whip and barbed wire fence. Now previously, I have used that fence as an antenna for the excellent little Tecsun PL-310ET, with some nice results. However, after this series of tests, my views on the fence have changed a little. Obviously it might be somewhat directional and earthed along it’s length, neither of which I’ve checked, however, notwithstanding these performance-related factors, the performance of the whip which at home had been terrible, surprised me greatly. Text links to a set-up video and the reception videos on my Oxford Shortwave Log YouTube channel follow directly below, with embedded videos at the end of the post.

Finally, if you’re looking for a well performing, compact and portable active antenna for outdoor use in quiet environments and of course, DXpeditions, I would definitely recommend the Boni whip. Just bear in mind that the SNR it delivers at home might not be usable for anything more than casual listening.

Oxford Shortwave Log: Sony ICF-SW77 vs ICF-SW55 vs Tecsun PL-310ET

3 Replies

Hi there, I recently posted an article regarding a couple of recent DX catches with the Sony ICF-SW77 receiver and went on to explain the background to a multi-receiver test I had started conducting, comparing it with its stablemate of the time the ICF-SW55 and, just for the hell of it, a more modern, yet modest portable in the shape of the brilliant little Tecsun PL-310ET. Sony ICF-SW77

The initial results confirmed the performance of the Sony receivers to be very similar and thus the justification for the original price delta of £100 in the UK to remain in question. The first target signals chosen and in the original post were ABC Northern Territories on 4835 kHz and Radio Mali on 9635 kHz.

Sony ICF-SW55 Tecsun PL-310ET

The initial results reinforced my view that the PL-310ET is a great portable for relatively small money; it managed to copy both signals, something you might not expect from what is essentially a budget receiver.

Below are links to the next 6 reception videos on the Oxford Shortwave Log YouTube channel and once again, featuring all three radios. I have used two different antennas during the testing – a 75 metre longwire and the Wellbrook ALA1530 active loop, running on batteries. The accompanying text description to the videos indicates which antenna was used.

Although the PL-310ET clearly struggled with the more ‘hard-core’ DX signals amongst those detailed below, the fact is, for less than £40 in the UK (and I’m certain even less elsewhere), Tecsun have delivered us a portable radio that really is capable of real DX. With DSP, a number of audio bandwidth filter options and great sensitivity, it’s a winner for beginners to DXing and to ‘old hands’ who want a radio in their pocket when they take the dog for a walk for example (something I do all the time – you never know when you’re going to come across the next barbed wire fence!). As for the Sonys, well I’m still not convinced one way or the other that the £100 price delta on the original price of the ICF-SW77 was worth the money – the ICF-SW55 is pretty close to it in terms of delivering discernible audio across all of the below reception videos. I’d be interested in your views and note there will be a final posting on this 3-way receiver comparison to wrap things up. In the meantime, thanks for reading/watching/listening and I wish you good DX!

Video: Gary DeBock’s “Baby FSL” antenna

2 Replies

Many thanks to SWLing Post contributor, Gary DeBock (N7EKX), who shares this video and notes the following on YouTube:

This is the new 3.5 inch (89mm) “Baby FSL” antenna, designed to provide a powerful DXing gain boost for Ultralight radios (or any other portables) despite its very small size. It has 32 Russian surplus 140mm x 8mm ferrite rods and 31 turns of 1162/46 Litz wire. In the demonstration video it provides a daytime DX gain boost for 750-KXTG (Tigard, Oregon, 50 kW at 160 miles) from inaudible up to about S7 on the Eton Traveler III Ultralight radio.

Gary is certainly a first-rate DXer and an ambassador of our radio hobby. Gary shows us here that, with a little ingenuity, we can take a $50 radio and turn it into something exceptional! Homebrewing at its best. Thank you, Gary!

Also, I had never considered that a high-gain FSL antenna would require very precise placement of the receiver for proper inductive coupling. It makes sense, though. This loop is tuned for razor-sharp precision!

Some day, when I have a little free time, I’m going to build one of Gary’s FSL designs.
