Tecsun S-8800 update

UPDATE: Click here to read our full review of the re-engineered Tecsun S-8800. Note that the post below refers to the first production run units only.

If you’re considering purchasing the Tecsun S-8800, this is an important post.

I’ve had the S-8800 for about two weeks and had planned to have audio clip comparisons prepared and posted by now. My exceptionally busy schedule has made this difficult–and there a few other complicating factors.

First off, the good news: in terms of sensitivity, selectivity and audio fidelity, I’m very happy with the S-8800. I’ve compared it a number of times with the Tecsun PL-880 and the Sony ICF-SW7600GR and it either holds its own or even has a leg-up on both radios in terms of overall performance. I find that the S-8800’s AGC is more stable than my 1st generation PL-880.

Of course, what will be most telling is what you, dear reader, think of the performance when compared in a blind audio test.

As I mentioned, though, there are complicating factors–It’s not just my schedule which has made the S-8800 review come to a halt.

Birdies…

Yes, birdies. Lots of them.

At first, I thought the noises were due to the fact my mobile phone and Zoom H2N digital recorder were too close to the S-8800. I dismissed this interference as it didn’t sound like the typical steady tone/carrier birdies I’ve come to loath over the years.

As my testing continued, though, I quickly realized these variable heterodyne and digital hash noises must be internally-generated.

Quite literally, as I was outdoors testing the S-8800 and making this discovery last week, I received a message from SWLing Post contributor, Bertrand Stehle (F6GYY). You might recall, Bertrand provided us with an initial review of his S-8800e (the European version of the S-8800). He also started noticing the birdies and, like me, initially assumed they were due to an external source of RFI.

Bertrand kindly mapped out the extensive list of birdies he found on his S-8800e–he noted a total of 81 birdie/carrier locations:

14 birdies on longwave
4 birdies on mediumwave
63 birdies between 1859 – 29095 kHz

Comparing notes, there are some differences between Bertrand’s S-8800e and my S-8800:

Only 50-60% of the birdies on my S-8800 are in the same frequency locations as those mapped by Bertrand on his S-8800e
The total number of birdies, however, are likely identical–I find birdies where Bertrand hadn’t noted them

The appearance and intensity of the birdies can vary depending on listening location and the strength of any nearby broadcast signals. I’ve noticed four distinct birdie sounds: a variable carrier, a steady carrier, digital hash, and something I might describe as digital variable noises.

I’ve even noticed some change slightly as you move the radio around.

Here are a couple of examples:

Example on 2009.15 kHz:

Moving forward

Obviously, this is a major issue for an enthusiast-grade portable.

I’m sharing all of this information with Anna at Anon-Co. No doubt, she’ll share this information with Tecsun engineering. The last I heard, projected availability of the S-8800 from Anon-Co is late March 2017. Perhaps there will be time for Tecsun to eliminate these birdies by improving internal grounding and/or shielding?

Until the birdie issue is sorted out, I’m not proceeding with audio comparisons or a full review. It goes without saying that, at present, I couldn’t recommend purchasing the S-8800. Sad, because this is otherwise a great radio.

I hope Tecsun can sort this out, though.

I will share any/all updates here on the SWLing Post.

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 brilliant little Tecsun PL-310ET: serious DXing on a budget – part 1

20 Replies

Hi there, a good friend of mine Mr Thomas Brogan mentioned to me recently that his little Tecsun PL-310ET was proving to be an excellent receiver and that it would suit my DXpedition activities. Now, as someone who likes to push the envelope of performance with sophisticated portables, usually coupled to very large antennas, a cheap little Tecsun might not have been an abvious choice for my next purchase. However, Mr Brogan (who has an excellent Youtube channel by the same name – check out his wonderful collection of vintage and modern receivers) previously suggested I buy, for similar reasons, the Sony ICF-SW100. That little masterpiece of electronics turned out to be one of the best receivers I’ve ever owned. I felt compelled to take notice because Tom never gets this stuff wrong! A few days later I found myself in Maplins – again – and there it was on the shelf at just under £40, so I bought one.

I got back into shortwave listening about 18 months ago, after many years of inactivity whilst my poor Sangean ATS-803A rotted away in the garden shed and Sony ICF-7600G long-gone via eBay. To start all over again, I bought a Tecsun PL-360. What a great little portable that turned out to be – there are over 100 reception videos on my YouTube channel demonstrating how it continually performed above and beyond the very modest price tag. I even managed to hear ABC Northern Territories 4835 kHz on it once – simply amazing for a receiver under £30. Given my extensive experience with the PL-360 and having learned the PL-310ET shared the same DSP chip, I was expecting the same, or at least very similar performance and the only real benefit to upgrading to the PL-310ET was the direct frequency access. However, I was wrong about that!

The brilliant Tecsun PL-360 got me back into shortwave radio for less than £30

About a week after buying the PL-310ET, I managed to get out on a DXpedition and with 30 metres of wire attached to it via the external antenna socket, I started tuning around the SW bands. Quite simply, I was amazed at the sensitivity and selectivity of this diminutive little portable. With the proven DSP receiver chip and a number of audio bandwidth filter options from 1 to 6 kHz, coupled with direct frequency access via the keypad, it was a joy to use and listen to. In just over an hour I had copied signals from North Korea, including their internal service KCBS Pyongyang, Zanzibar BC, ABC Northern Territories (at the first attempt!), Zambia NBC Radio 1, Radio Oromiya and Radio Amhara from Ethiopia, amongst others. Brilliant stuff and clearly demonstrating that the overall hardware/software package with the PL-310ET is a step up in performance over the PL-360 and capable of proper DX for a very modest outlay. Interestingly, in a conversation with Thomas Witherspoon regarding the PL-310ET, he reminded me that it was one of his go-to radios for travelling and confirmed it’s excellent performance. I would definitely recommend this radio to novices and experts alike.

Reception videos follow below, with more to come in part 2; I hope you enjoy them. Thanks for watching/listening and I wish you all excellent DX!

Which is the best? Sony ICF-2001D/2010 or ICF-SW77? Part two

Which is the best? Sony ICF-2001D/2010 or ICF-SW77? The halfway score

4 Replies

Hi there, here is a summary of the first half of tests comparing the Sony ICF-2001D against it’s replacement the ICF-SW77. Both receivers are widely acknowledged as being amongst the best shortwave portables ever made, but how close are they in performance? Is there a clear winner after the first 8 reception tests? I hope you enjoy the summary video. Links to the first half of reception tests follow again, below, whilst the second half will follow in a separate post. Thanks and good DX to all.

Which is the best? Sony ICF-2001D/2010 or ICF-SW77?

11 Replies

Hi there, subscribers to my YouTube channel Oxford Shortwave Log will be aware that I currently operate both of these wonderful vintage portables. I purchased the ICF-2001D only 18 months ago from eBay, based largely on its reputation as one of the best performing portables ever made. Previously I had been using my excellent ICF-SW55 as the mainstay receiver for my numerous DXpeditions, coupled with irregular appearances from my Sangean ATS-803A and the excellent value-for-money Tecsun PL-360. The ICF-2001D proved to be a revelation in terms of sensitivity, selectivity and contrary to popular belief, with careful planning (to avoid crowded bands), is able to cope pretty well with very large antennas. As regards audio bandwidth filtering, SSB and synchronous detection, in my experience, the ICF-2001D is as good as it gets in a portable – or a vintage portable at least. I have lost count of the number of personal-firsts I’ve achieved using this wonderful receiver and as someone who likes to push the envelope a little, I soon started to wonder whether it’s replacement, the ICF-SW77 might prove to be an even better performer. Subsequent online research confirmed there was no absolute consensus on this issue, with followers of these two great receivers firmly placed in both camps.

Sometime later, a good friend of mine, fellow radio hobbyist and subscriber to Oxford Shortwave Log very kindly offered to send me his cherished ICF-SW77 on long-term loan. Like me, he was intrigued to know how it compared to it’s venerable predecessor and thus the deal was done! Upon it’s arrival in July, I started planning a back-to-back series of comparison tests at the very quiet wood in Oxfordshire I used for my DX’peditions, using the same antenna for both recievers – the excellent Wellbrook ALA1530 active loop. In total, I made fourteen reception videos comparing the ICF-2001D and ICF-SW77 and posted them to Oxford Shortwave Log. Both receivers performed very well, delivering excellent reception on the Tropical Band and elsewhere on the shortwave spectrum from Bolivia, Brazil, Guatemala, amongst others. At the halfway stage, I generated a video to summarise the results to-date and this will follow in my next post to swling.com. In the meantime, I hope you enjoy the first half of the reception videos; which follow below:
