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…

26 Replies

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!

A quick view of my shack in Oxford, UK & recent transatlantic medium wave DX

3 Replies

Someone recently described my shack in Oxford as ‘an impressive mess’…. and that really is just about the most positive comment I’ve ever received regarding my listening post! So, my apologies for displaying the mess in public, but in response to having been asked many times by subscribers to Oxford Shortwave Log to ‘share my shack’, here it is, well most of it at least, in all it’s unadulterated glory.

The primary reason however for this post is to share my most recent transatlantic medium wave catches using the brilliant Elad FDM DUO and Wellbrook ALA1530 magnetic loop antenna. This excellent combination continues to pull in really nice DX, although not so much very recently as propagation has been fairly rubbish. However, since early to mid December, the dynamic duo have managed to pull in a number of transatlantic medium wave signals, including Radio Rebelde, Cuba on (670 and 710 kHz), KVNS Texas, CHIN Radio, Toronto, WFED Washington DC, WWNN Health and Wealth Radio, Pompano Beach, Florida, and huge signals from WMEX Boston and WWKB Buffalo, New York. Embedded reception videos and text links follow below and in the mean time, I wish you all great DX!

Video: Juan touts Panasonic RF-2200 performance & filter shapes

Many thanks to SWLing Post contributor, Juan Pablo Carlino, who writes:

Hi. I own one RF-2200 after buying it in eBay in March 2008. Since then it became my favourite portable radio and as everybody [has commented], its a pleasure to hear MW with it.

I explain this due to the fact that it has a good rotative ferrite antenna and also because the narrow and wide filters have a suitable shape for MW: at least in my country each MW is spaced from the other by 10 KHz, so you don’t need a very sharp filter. The narrow one is not so narrow, just enough to attenuate maybe 6 db the splatter from the louder station and not loosing audio quality.

When you tune around you have the impression that the filter shape suites perfectly for MW, making the audio quality very pleasant. I would never sell it. If you are interested i’ve captured a short clip while playing with it outdoor on 7 MHz band, hearing ham stations on AM, SSB and CW.

Pay attention to how loud and clear i was hearing stations at 400 Km in AM:

Many thanks for sharing your thoughts, Juan!

I agree with you completely. At least here in countries where MW stations are spaced at 10 kHz, I find the RF-2200 a mediumwave DX boss!

I’m constantly amazed with the RF-2200’s MW sensitivity and selectivity–and low noise floor. That combo, along with the filter shapes Juan mentions and the excellent built-in full-fidelity speaker make for a proper listening experience.

As I’ve said before, the RF-2200 is a radio with fortitude and purpose.

The only place I’ve ever really searched for an RF-2200 is eBay. I like eBay, because if you receive a faulty unit, you can typically return it or have some sort of recourse (as long as the seller accepts returns).

I would only buy an RF-2200 (or any vintage solid-state rigs) from a seller that has near 100% ratings with a number of radio sales in their past. That is, if you’re seeking a working unit.

Though the RF-2200 is vintage and thus might eventually need repair. It’s ultimately reparable by a skilled technician, though. My buddy Vlado, for example, has repaired 2200s in the past–indeed, we cracked my RF-2200 open a few months ago to clean contacts.

Panasonic RF-2200s typically cost between $175-300 for one that’s mechanically and cosmetically sound. Of course, NOS units go for much more and units with faults sell for much less.

I expect my RF-2200 will outlast me!

Tecsun S-8800: Unboxing, photos, and initial impressions

32 Replies

UPDATE: Click here to read our full Tecsun S-8800 review.

Yesterday, I received a Tecsun S-8800 from Anon-Co in Hong Kong.

I like opening radio boxes to find a cardboard insert like this one. It protects the radio and has so much less waste and individual cardboard bits inside.

As I always do when a new radio comes on the scene, I requested to purchase an early release of the Tecsun S-8800 radio for review months ago. But this time, my contact at the Chinese distributor Anon-Co, Anna, insisted on sending us one “as a gift for the Chinese New Year of the Rooster.”

Because I’ve worked with Anna at Anon-Co for at least a decade, having purchased numerous radios for review and as gifts for family and friends, this was difficult to refuse. I decided there was no need to do so. Each time I do an in-depth review and note shortcomings or deficiencies in the radios I’ve purchased from Anon-Co, Anna immediately passes my feedback and criticisms directly to the manufacturer’s engineers. I believe this feedback loop between customers, reviewers and manufacturers leads to improved product iterations. Of course, sometimes the negatives can be so problematic, manufacturers simply drop the product line and move on (remember the Tecsun R-2010D? Case in point). So, while there are a number of other eBay retailers in China that distribute Tecsun radios, I prefer Anon-Co for these reasons.

Thank you, Anna!

The S-8800 is packed face-down to protect the front panel.

Manufacturers and retailers who send me products for review know that we radio geeks have fairly high expectations of our gear, and will therefore hold them to exacting standards. I’m not the least among these. While I endeavor to be realistic, understanding producers’ limitations and the need for product growth, I also try to keep my reviews as objective as I can, and accommodate my own and others’ particular requirements and preferences.

So In the spirit of full disclosure, I must note that I’m not as avid a user of large portables like the S-8800 (or the Grundig GS350DL, S450DLX, or the C.Crane CCRadio-SW).

Personally I prefer smaller, full-featured travel-friendly portables, or else larger tabletop models. Radios with a form factor like the Tecsun S-8800 are an “in-between” product in my world, thus I rarely use them.

That said, every month I receive questions from readers looking for this very “large portable” form factor. Some hobbyists enjoy a radio that’s easy to operate, featuring simple controls, robust audio, and dedicated external antenna connections. For these listeners, a large tuning knob and generous display are more important than things like SSB and synchronous detection.In other words, they want a broadcast receiver. Some have literally asked for a modern version of the venerable Panasonic RF-2200 (which I admittedly love, an exception to the rule of my avoidance of large portables). In terms of aesthetics, it’s impossible to live up the legendary solid-state RF-2200, in my opinion…kind of like comparing a modern muscle car with the 1960s original from which it copies its design.

The S-8800, and its many predecessors, were certainly influenced by the RF-2200’s popular design & form factor: large speaker on the left, large tuning knob, wide-spaced knobs, and a generous display. Like the RF-2200, it has a durable, adjustable woven carry strap.

The S-8800 ships with the accessories in the photo below: an IR remote control, two rechargeable cells, an RF adapter, and a USB charging cable.

Note the charging cable is only a cable; the S-8800 doesn’t ship with a wall-wart type charger. If you’re like me, you probably have a handful of USB chargers scattered around your home that you could use for the purpose of charging this radio. And if you don’t, you can also use any free USB port on your PC to charge it.

USB chargers are cheap and well-known to spew RFI. I doubt you’ll enjoy listening to shortwave or mediumwave/AM while charging the S-8800’s internal cells. It doesn’t appear the S-8800 was designed for listening while plugged in; Tecsun clearly wants you to charge it and then listen, off battery power. The latter is my preference for listening anyway, but it may put off some potential S-8800 owners.

The display is easy to read from any angle, and it’s also easy to view in bright sunlight. In low light, you’ll be pleased with the backlight function.

On the right side of the S-8800, you’ll find an internal/external antenna switch, a DX/local switch, RCA type stereo line-out ports (covered in the photo above) and a stereo headphone jack.

On the back, you’ll find a mini USB port for charging, an antenna port for a radiator and ground wire, as well as an FM antenna port.

The battery cover is predictably located at the bottom of the back panel and––a first for any shortwave radio I’ve reviewed––accommodates two (supplied) 3.7V Li-Ion (internally) rechargeable cells.

The right side panel has no connections or controls.

I must admit…the Tecsun S-8800 has some front panel controls I really appreciate. Most notably, it has a dedicated AM bandwidth selector and fine tuning control. I also like the dedicated treble and bass controls which can also be found on its predecessors’ front panels.

Over the next week, I’ll be evaluating the performance of the S-8800. I plan to post blind audio samples as I’ve done in the past, comparing the S-8800 to other portables: likely the PL-880 and the ICF-7600GR, PL-660 or PL-680. Please be patient, however, as making these recordings takes time as I like to make sure each radio has a true representative sample and fair shot at showcasing performance.

What about those initial impressions? Yes, I must say I do like the package of the S-8800 better than its predecessors. I like the dedicated IR remote control, the many antenna connections, and, so far, the audio fidelity from the built-in speaker. Makes for a nice package.

But, ultimately, the proof is in the pudding: let’s put the S-8800 on the air and compare it with some benchmarks!
