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!

Many thanks to SWLing Post contributor, Ashok Shankar Das, who shares the following guest post originally published on his blog SWLDAS:


International Radio Fair and World Radio Day

by Ashok Shankar Das

For last few years Outreach International used to organize a radio fair. This year too they organized “International Radio Fair 2017” at Bhubaneswar, Odisha. Besides other participants, Amateur Radio Society of Odisha (ARSO) participated in the fair too.

Main Attractions

The main attractions of this fair was HAM radio, vintage radio collection and radio related stamp collection.

International Radio Fair 2017 Bhubaneswar, Odisha.

The Sand Art for World Radio Day in the venue

Vintage Radio collection

Mr. Ghanasyam collected several radios Most of them are vintage tube radios. Though they are non functional but for a museum it is very nice to see radios from my Grand fathers time. Around 500 to 600 radios were on display.

Mr. Ghanashyam in his 80s now a radio lover, I would say Radio Crazy man.

Vintage Radio Stall from a distance.

Few Radios with close-ups.

His collection includes several radios from Philips, Murphy, Bush and HMV to name a few…

Radio Philatelist

The other attraction is Philatelist Mr. Ashok Kumar Tiwari. his collection includes Radio inventors/researcher, development of radio, broadcast history, Emergency Communication and HAM radio. A very nice and exhaustive collection.

Alexander Popov

J.C Bose

G.Marconi

HAM radio related.

I could not put all the pictures of his collections, its huge…

Last but not the end…

The HAM radio stalls

In this category ARSO Bhubaneswar and ARCCS from Kolkata put up their stalls. Evan they have made a special call-sign for this Event(AT0IRF). In ARCCS stall, they have displayed and try to promote ON-AIR and how to reach out more people. On the other hand ARSO team focused on HAM radio Homebrew and Radio concepts.

VU2ABG from Surat came to meet ARSO team.

Concluding remarks

Though it was a very nice initiative, participation should have been more. Though it is organized jointly by UNESCO no International participation seen. hope coming year these shortcomings are fulfilled.


Ashok, thanks so much for sharing your photos and comments from the International Radio Fair and World Radio Day in Bhubaneswar.

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 610 kHz:

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.

Troy updates the Tecsun PL-880 hidden features reference sheet

Many thanks to SWLing Post contributor, Troy Riedel, who has recently added the hidden bandwidth adjustment feature to Cap Tux’s excellent PL-880 reference sheet.

Here are links to download the updated sheet:

I will also add this to the Complete list of Tecsun PL-880 hidden features page: a place where you can comment if you note any previously unpublished PL-880 hidden features.

Thanks again, Troy!

eBay find: The IFR Aeoroflex T-1200SRA

The Aeoroflex T-1200SRA receiver

Many thanks to SWLing Post contributor, Mario Filippi (N2HUN), who writes:

Every once in a while an IFR (Instrument Flight Research, a.k.a. Aeroflex) T-1200SRA comes up for auction, it is a sophisticated receiver covering LF-HF-VHF-UHF with built-in spectrum analyzer.

Click here to view on eBay.

Some claim these were used by the FCC for surveillance. I can believe that as IFR is a professional manufacturer of commercial radio test equipment. I have their 500A service monitor.

Beautiful receiver, but this one is way overpriced. They usually start around a grand or so with a “Make Offer” contingency. One was sold in December for $481.

Click here to search eBay for a T-1200SRA.

Thank you for sharing this, Mario! Knowing the IFR is essentially a piece of test equipment, I’m very curious how it  might compare with a similarly-priced tabletop (broadcast) radio.

Post readers: Anyone else own a IFR T-1200SRA?

Dan compares the Tecsun PL-365 and CountyComm GP5-SSB

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following review:


Comparing the CountyComm GP5-SSB and Tecsun PL-365

County Comm GP-5/SSB and Tecsun PL-365: a couple of years ago, I obtained a GP-5/SSB from Universal and have enjoyed using the radio. It’s extremely sensitive, often bringing in signals in the middle of my house here in Maryland, and is fun to use, provided the auto-tune is done to insert frequencies so you don’t have to use the thumb wheel too much.

I have often thought that the next logical upgrade for this radio would be to add a small keypad to allow direct frequency selection, but perhaps that is not in the cards. The County Comm is basically the Tecsun PL-365, but the actual Tecsun version has not been available for the most part from major sellers, even from Anon-Co in Hong Kong, or Universal. You can still find some PL-365’s from certain Ebay sellers. Last year I obtained two from a Hong Kong seller. Both were NIB, and arrived within about a week or so of purchase.

What I noticed immediately is that the PL-365 has a different kind of exterior surface, more rubberized than the County Comm. I was curious about any differences in performance that might be obvious. Recently, I took both outside for a very basic comparison — not scientific by any means, but I think it shows something that I have noticed.

Both share the characteristics of extreme directionality, and sensitivity to touch — sensitivity increases markedly when they are hand-held, decreases noticeably when they are left standing on their own, or angled. I have noticed this when using them at the beach. If I am recording a station, and leave the radio alone for a few minutes, I return to find reception degraded quite a bit, because they were not being held.

In my very basic comparison, I had both receivers next to each other on a backyard table, both antennas fully extended, full batteries on both. While on some frequencies, at least initially, it seems little difference can be heard, on others there is what seems to be greater clarity and signal separation on the PL-365.

I noticed this from the start on 13.710 where the County Comm appears to be noisier than the PL-365, and on the portions later in the video when both are tuned to 11.820 (de-tuned to 11,818) Saudi Arabia, and to 11.945 khz.

Apologies for the length of the video. It’s hard to draw any conclusions based on this comparison, and I intend to do some additional tests with both my PL-365s and will report back on any findings, but I thought this would be of interest to those of you out there with these fine little radios.

Thank you for this review and comparison, Dan. I’m often asked if there is any difference in performance to justify the extra costs typically associated with the PL-365. I can now share this video and your review–potential owners to draw their own conclusions. 

The Tecsun PL-365 can occasionally be purchased through sellers on eBay. The CountyComm GP5-SSB can be purchased from Universal Radio or CountyComm.

The versatile Kenwood TH-F6A

In reply to my recent post about the Yaesu VX-3R, SWLing Post reader Tha Dood comments:

[The Yaesu VX-3R] is a neat little HT, but the Kenwood TH-F6A is way more versatile.

How? Full 5W on 2m, 222MHz, and 440MHz, and will RX 150KHz to 1.3GHz in AM, FM, FM wide, NBFM, USB, LSB, and CW. All that in a size of a pack of cigs. Yes, it will overload easily, but something that wide banded and this small, I kind of expected that.

However, want to hear what your wireless FM innercom sounds like on 175KHz? You can do that. Want to hear what your 222.1MHz transverter sounds like on SSB? You can do that. Need to tune-in to local AM / FM radio when power goes out? You can do that. Want to listen to CB CH19 truckers gripe about traffic conditions? You can do that. Want to listen to aircraft traffic at an air show? You can do that. You want to monitor 6M 50.125MHz USB to hear when that band opens? You can do that.

No, it doesn’t have D-Star, DMR, Fusion, or even SW’s DRM, but analog-wise this HT is so versatile, what else is out there like it?

Thanks for sharing your thoughts about the TH-F6A!

A couple more things I like about the TH-F6A:

  • it meets MIL-STD 810 C/D/E standards for resistance to vibration, shock, humidity and light rain
  • It has a dedicated number keypad for direct frequency entry (something, sadly, the VX-3R lacks)

I’ll put the TH-F6A on my “wish list” this year and perhaps give it a thorough review. (Perhaps Santa Claus is listening!?)

Here’s a snapshot of TH-F6 pricing at time of posting:
