Re: Ultralight quality control: Sangean DT-400W

Hello Michael, Paul, David and All,
 
<<<   Gary,  Alongside the FSL articles, your shootouts have indeed been excellent
and inspiring.  
Perchance time for a shootout update to include more recent ultralights???
It would also be valuable to know which have been the most reliable over the
years.   >>>
 
That would certainly be a worthy project, Michael, and if I had the necessary hobby time available, it would be an honor to provide such a service for the Group. Unfortunately there are already a couple of ongoing major projects here (MW and LW upgrade loopsticks for the Sony ICF-2010 model, and an all-new 19" FSL antenna project) which are very challenging, and require a serious time commitment to complete.
 
To assist those new members of the group in purchasing their first Ultralight radio, I will post the links to all of the radio reviews that I have written previously (including the three major Shootout reviews) below. My own assessment of the current Ultralight radio market is that although there have been some new pocket radio models introduced since my last review (for the Tecsun PL-606 model) was written in December of 2010, there have been no "game-changing" breakthroughs in any of the new models. Almost all of the most popular Ultralight Radio models currently being used for both transoceanic (split-frequency) and domestic DXing have been reviewed in one of the articles linked below. The most popular models for transoceanic (split frequency) DXers are the Tecsun DSP Ultralights (PL-380, PL-310 and PL-606) and the most popular models for domestic DXers are the Sony SRF-T615, Sangean DT-400W, Tecsun PL-606 and Sony SRF-39FP (analog).
 
73 and Good DX,
Gary DeBock (in Puyallup, WA, USA)

I've read Gary's Shoot-Outs many times as well as a number of his other papers on Ultralight radios (thank you!) and refer back to them.   In fact, they - along with opinions formed from this list - form the basis for the receivers that I am considering.  I was particularly struck by recent remarks by Rob Ross and Richard Allen about the performance of the DTS-400W relative to the SRF-T615.  

My initial email was an attempt to prompt a discussion to see how the radio has fared over the years as well as the quality control issue that I cited, with an eye toward finding out if current production units had developed any issues.  I certainly was n't going to ask for a new Shootout, that is an awful lot to ask, but rather to build upon the initial results, if possible.

Lastly, I should add that I was going to pose some questions about a few other rigs, with the same thoughts in mind.

Re: Ultralight quality control: Sangean DT-400W

Gary DeBock
 

David,
 
The Sangean DT-400W was one of five Ultralight Radios which were given very thorough reviews in the 2008 Ultralight Radio Summertime Shootout article, posted at http://www.mediafire.com/view/2t5godzzyaw/2008UltralightAMRadioSummertimeShootout.doc  The other Ultralight Radios covered in the review were the Eton E100, the Sony SRF-S84, Sony SRF-M97 and Sony M37W models.
 
The Ultralight Radio Shootout reviews were some of the most popular articles that I've ever written, and there were also major "Shootout" reviews in the Spring of 2008 and in the spring of 2009. These pocket radio reviews really helped the ULR craze get off of the ground.
 
I personally have two of the DT-400W models, and both of them have worked very well during the rare times that I've turned them on the past 6 years.

David:

   I have a SANGEAN DT-400 Ultralight….and pretty much all of the ULR's that are
worth owning. At one point I had 24 ULRs at the heyday of my ULR Career!!!!

As for the DT-400…I love it!! If the Sony SRF-T615 had never been invented…I
think the DT-400 may well have been my ULR of choice for serious DXing. The
Tecsuns are great too…but I really like the DT-400's ease of operation. It is
simple to use and the ergonomics are nice!! It reminds me of the Old 1950's/60's
Pocket Transistors I used to collect. You don't wanna know how many of those I
had…but well over 500, including several SONY TR-63's which was SONY's first
true "Pocket" Transistor in 1957. They did make a few Transistor Radios before
the TR-63…but those were more of a COAT POCKET RADIO than a Shirt Pocket Radio!!

Anyway…I don't think you can go wrong with a DT-400…I bought mine when they
first came out and I would not sell it……

Would I chose it over the T615…..No way. I have 4 - T615's…2 currently in
action, and 2 New In Box sitting at the ready should I need them.

For me….The DT-400 is a Nice Little Radio……….The T615 is the King in my
Opinion…… unless of course you live in Newfoundland, then you can use any ULR
and hear the world!! HAHAHHHA……

Re: Ultralight quality control: Sangean DT-400W

I have literally hundreds of portable radios, and there are many times more failures in Sangean than SONY, so mostly I buy SONY now days. Untimely 'deaths' of SONY radios are extremely rare in my collection and mostly when they employed new technologies years ago.
 More and more SONY radios are actually assembled in China, but use SONY chips [ I think].
I have have many non ULR's from SONY which do a very good job in the $50 class.
 I had good luck DXing with the ULR model  ICF-S22 and the AM only ICR-P15  certainly hears a lot of stations and would be interesting to DX with if approved..

Both my first two versions of the CCrane radio had total failures just out of warrante involving the displays, so Sangean certainly has had time to correct that sort of problem over the years if they wanted to.

Happy December to all & thanks to Paul for the kinds words about what i've been hearing lately..a good, mostly noise-free location (with a semi-spectacular ocean view) & the PL606 are a nice combo (occasionally patience & imagination help, too)..

7465 (Kranji)/17640 (Ascension) BBC 1635+ 30 Nov. Sat back & enjoyed play-by-play of the Tottenham/Everton match.
 
15420 BBC (Meyerton) 1545+ 2 Dec. Sports news w/ feature on the Trinidad/Tobago women's soccer team getting close to qualifying for the World Cup, weak w/ //7465 much better. 

15940/15970 CNR1 1553-1600* 30 Nov. Jamming SOH here, on 7385 echo-jamming RTI, & 7570 jamming VOA (after 1600) + regular sked on 7305/7365.

13810 RTI (Issoudun) 1641-1657* 30 Nov. EG with closing ID..Aoki says jammed, but it sure doesn't sounds like it.

11517 VoT (Dushanbe-Yangiyul) 1435-1500* 1 Dec. Site presumed & apparently an alternate freq. to 11512..TB chat w/ nice musical interludes..CNR1 jammer only a vy weak carrier on 11510 @ 1435 but much stronger by 1455 (just in time to close @ 1500 with a flourish), 1439+ 2 Dec. as well, so perhaps this is a "permanent" freq. change? CNR1-11510 jammer much stronger today, but just as ineffectual.

**11530 RP (Islamabad) 1435-1500* 28 Nov. Thanks to Ivo Ivanov's info on the HC-DX site, my unID seems to be Pakistan--seriously disturbed audio/wobbly carrier..recheck 1442-1500* 1 Dec. found much cleaner audio but modulation still very sub-par..occ. Urdu words & some songs made it through..sked 1330-1530 & irregular @ best, but still a treat to hear..2 Dec. RP only "imaginary-level" audio @ 1440 check.

11635 TWR-India (Yerevan-Gavar) 1503-30* 1 Dec. Chat & "sub-continental" style hymn-y tunes, Post Box #s for listener comments @ :15, more chat & slightly more "Bollywood" style tunes to BOH w/ TWR website/POB in Maharashtra, music box IS & off..sked in Gamit 1500-1515, Mouchi 1515-1530 on Mondays & Urdu 1530-1600, but unless they started the Urdu programme pretty late, it wasn't on today.

15580 VOA (Selebi-Phikwe) 1539+ 1 Dec., 1532+ 2 Dec. Listeners' requests (including MC Hammer "Can't Touch This", Britney Spears, Taylor Swift) during Larry London's music show..sked 14-16 & usually puts in a nice signal daily..also hearing (in a wishful thinking sort of way) VOA (Selebi-Phikwe) on 4930 in // (even with the PL606 hooked to the 6m Xwire, the signal is extremely marginal @ best), still, the possibility of a ULR logging of a 60M African via LP is intriguing.
 
Hope everyone has a fine week..good listening, y'all..

David,

I have been using my DT-400W for at least 3 years or more.  The only problem/annoyance I've experience with mine is that the UP/DOWN tuning buttons have become very sluggish.  Instead of the "new-button" tactile feel, you can barely feel them move when depressed.  They still work, but I'd rather they work like they did when the radio was new.

The display and backlight work just as they did out of the box.  I have had no problems with the volume thumbwheel getting scratchy.

I liked my DT-400W so much that about a year after I purchased it I bought another one to have as a backup.  Maybe I need to start using it, hi!!

I own several Sangean AM/FM pocket radios.  I have been most pleased with their ergonomics operation. My biggest gripe is not with the radios, but with finding earbuds/earphones with an audio response such that I can hear both spoken voice and music.  I have significant hearing loss in both ears, but that's another story, hi!

Hope my reply helps!!

Subject: [ultralightdx] Ultralight quality control: Sangean DT-400W



As one who has been around ultralights for a few years, and radio in general for ages, it seemed natural to me that I would start looking around at adding another radio or two.

However, there are what might be quality issues with some manufacturers.  In particular, I am somewhat concerned at the reports of display failure in at least a couple of Sangean DT-400Ws, well within what one would expect a normal radio lifetime to be.  I also am aware of display failure in a Sangean PR-D5 within a year or two. At face value, that would seem to be a different animal, but I'm unsure because it's possible that the displays might have the same source.

I am fully aware of the fact that these radios are all made in the China and that quality control is only as good as the parent manufacturer makes it.  And yes,the old saying that "you only get what you pay for" comes into play, but only to a point because there are success stories at radios with low prices.

Earlier this year, I read what seemed to be the strong recommendation by two prominent ultralighters of the DT-400W, especially with respect to the Sony SRF-T615.  Given their credibility, I will admit that the DT-400W is a radio of interest...as are a couple of others.

So, would anyone care to offer input on the DT-400W and any potential QC issues?

Thanks in advance.

No pressure. I was just concerned that I might have missed it. I realise it requires a lot of testing, and we are all grateful to you for devoting so much time [and ferrite] to the issue. I'm happy that it will be worth the wait.

The upgraded Medium Wave loopstick (based on coil inductances from the stock model) was the easier part of the project, and was wrapped up fairly quickly. It is composed of two Amidon 7.5" Type 61 ferrite rods, wound with 100/44 Litz wire, and supported on a 16" orange plastic frame glued to the top of the ICF-2010. The Longwave loopstick design is the more challenging part of the project, starting pretty much from scratch in creating an all-new loopstick design radically different from Sony's stock antenna. The only way to do this is to create multiple Longwave loopstick test models and test them out (in competition) with signal generator inputs-- a very time-consuming process. This was the same process used in designing the all-new Longwave upgrade loopsticks for the Tecsun DSP Ultralight models (like the PL-380) in early 2011.

Hello All,
 
For those who are interested, a major update of the May 2008 article (posted at http://www.mediafire.com/view/404c61oxxbd992n/SuperchargingtheICF2010LargeComplete.doc , to greatly increase the MW and LW band sensitivity of the classic Sony ICF-2010 SSB receiver) is in the works. The updated article should be completed during the Fall season, and will provide specific instructions for transplanting and securing a much more sensitive loopstick into the Sony portable's circuitry. The new loopstick will be based upon recent Litz wire improvements.

Re: Supercharging the ICF-2010 SSB Receiver

Gary,
 
Did I miss this?
My 2010 emerged from a storage crate earlier this year, and I was going to try the 'new improved' loopstick. I didn't see the update, and couldn't find an article in the archive.
If I missed it, could you resend the link?

Hello All,
 
For those who are interested, a major update of the May 2008 article (posted at http://www.mediafire.com/view/404c61oxxbd992n/SuperchargingtheICF2010LargeComplete.doc , to greatly increase the MW and LW band sensitivity of the classic Sony ICF-2010 SSB receiver) is in the works. The updated article should be completed during the Fall season, and will provide specific instructions for transplanting and securing a much more sensitive loopstick into the Sony portable's circuitry. The new loopstick will be based upon recent Litz wire improvements.

November 8-10 Grayland Ultralight DXpedition Article

Gary DeBock
 

Hello All,
 
For those interested, a full article describing the 3-day Grayland Ultralight DXpedition conducted with the new 17" FSL antenna on Veterans Day weekend has been uploaded at http://www.mediafire.com/view/k7boymq62q2p5v1/November_2014_Grayland_Ultralight_DXpedition.doc  , and will shortly be uploaded to the Yahoo Ultralightdx file site. 
 
Describing the rare chance to take oversized items like the 17" FSL antenna and the 30" loopstick Sony ICF-2010 model to the ocean coast, the article includes multiple photos of the TP-DXing setup at the end of Grayland Beach Road, along with MP3 links for 39 Asian DX recordings made at the site. Thanks very much to Phil Bytheway for already posting summary articles of the DXpedition to the club bulletins-- this full DXpedition article was something that I had not planned to write, but suddenly decided was more interesting to complete than chasing wispy TP audio during dreary sunrise DXing sessions at my landlocked home location :-)
 
73 and Good DX,

Re: Ultralight quality control: Sangean DT-400W

Stephen Ponder <stephen_ponder@...>
 

David,

I have been using my DT-400W for at least 3 years or more.  The only problem/annoyance I've experience with mine is that the UP/DOWN tuning buttons have become very sluggish.  Instead of the "new-button" tactile feel, you can barely feel them move when depressed.  They still work, but I'd rather they work like they did when the radio was new.

The display and backlight work just as they did out of the box.  I have had no problems with the volume thumbwheel getting scratchy.

I liked my DT-400W so much that about a year after I purchased it I bought another one to have as a backup.  Maybe I need to start using it, hi!!

I own several Sangean AM/FM pocket radios.  I have been most pleased with their ergonomics operation. My biggest gripe is not with the radios, but with finding earbuds/earphones with an audio response such that I can hear both spoken voice and music.  I have significant hearing loss in both ears, but that's another story, hi!

Hope my reply helps!!

73 and Good DX!

As one who has been around ultralights for a few years, and radio in general for ages, it seemed natural to me that I would start looking around at adding another radio or two.

However, there are what might be quality issues with some manufacturers.  In particular, I am somewhat concerned at the reports of display failure in at least a couple of Sangean DT-400Ws, well within what one would expect a normal radio lifetime to be.  I also am aware of display failure in a Sangean PR-D5 within a year or two. At face value, that would seem to be a different animal, but I'm unsure because it's possible that the displays might have the same source.

I am fully aware of the fact that these radios are all made in the China and that quality control is only as good as the parent manufacturer makes it.  And yes,the old saying that "you only get what you pay for" comes into play, but only to a point because there are success stories at radios with low prices.

Earlier this year, I read what seemed to be the strong recommendation by two prominent ultralighters of the DT-400W, especially with respect to the Sony SRF-T615.  Given their credibility, I will admit that the DT-400W is a radio of interest...as are a couple of others.

So, would anyone care to offer input on the DT-400W and any potential QC issues?

Thanks in advance.

Hi Phil.

That is a 7.5" loopstick for MW which Gary built for me, it works very well :)

I notice you have a larger coil on your pl380. Is that optimized for LW? my 380 has a smaller wrap on the left of the rod.

Subject: [ultralightdx] DIY - Ultralight Radio Carry Case

 
Back in March 2014 I designed and built a custom "stealth ultralight dxing bag", this was designed to carry my 7.5" loopstick Tecsun PL-380 ultralight radio, my AR1733 radio and the various other bits and pieces I carry for portable ultralight dxing sessions. The details of this can be seen here: (http://ultralightdxing.blogspot.com.au/2014/03/diy-stealth-ultralight-dxing-bag.html)

Since recently returning to the ultralight DXing hobby after a few months being away, I decided to try and find a better carry solution, while the bag served me well and was cheap at around a $50 total cost, I have changed my approach and having to carry a separate bag (especially when also carrying other bags) became an issue to the point that I stopped carrying it as often.

Yesterday while shopping at our local Ship Loads I came across this case: (http://www.dinga.com.au/tackle-box-jw-197-utility-box-large.html) for $9.95. When I returned  home I found that it was the perfect size, however the foam sheet I had at home that I was planning on using for this was about 1cm too small the whole way around. 

After going to Bunnings to try and find some suitable foam and not having any luck, I happened to call past Kmart on the way home and found a Yoga block for $6 which was the perfect size. 

When I returned home I sat down to work on it and within 3/4 of an hour  I had the case set up how I wanted it. Materials used were:
- Jarvis Walker 197 Utility Box Large: $9.95
- Yoga form block: $6
- Black tape: $2.95
- Bubble wrap: $0.50

The foam block was cut to suit the size of the case and then I cut out sections to allow me to securely store both my AR1733 and 7.5" loopstick Tecsun PL-380 ultralight radios plus my aerial, notepad, pens and ear phones. This fits nicely in my backpack where I keep my logs sheets and larger accessories. It is still very 
stealthy and much easier to carry. I am really happy with how well this has turned out and for under $20 it is great value.

Re: Report - Portable Ultralight DXing Session - Queechy Lake

Paul Blundell
 

Thanks Gary, It is good to be back after a bit of a break away from the portable side of the hobby :)

Our baby is due soon so I am making the most of my free time now before she is born, after this for a while I will mostly be DXing from home. All going to plan I am hoping to do another portable session tomorrow night, this will be later just before our sunset so I hope I can log more stations, I am not 100% sure of the location as yet, maybe another lookout in Launceston I have used before or even a totally new location. 

I am on leave at the moment so have the time to do this.

I am glad to hear that you managed to log one new Australian station, better than nothing :)

Regards
Paul

Hello Paul,
 
Thanks very much for your latest Ultralight radio DXing report and video from Queechy Lake. It's great to have you back in the DXing activity, and read the reports from Launceston and the other Tasmanian locations.
 
My own luck in tracking down some new Australian MW stations wasn't the greatest this past summer, but 639-5CK was a new one for me while on the Oregon ocean side cliff of Cape Perpetua last August. Good luck, Paul, and thanks again for your Ultralight radio blog, DXing reports and videos.
