Re: Stock Sangean DT-400W Receives 6 TP's at Grayland

Dennis Gibson <wb6tnb@...>
 

My DT-400W arrived yesterday. Wow! The MW sensitivity is indeed
fantastic throughout the entire band. I'm a little disappointed with
the selectivity but I don't have anything similar to compare it to
(except a Sangean DT-110, which is on the turkey list and rightfully
so) so maybe I'm expecting too much. I have five locals within seven
miles (three are only a little over one mile away) but none are more
than 1 KW at night.

I can walk to the beach but I don't know anybody in California looking
for TP's so I don't know if hearing any from here (Santa Barbara) is
even feasible. I'd like suggestions on which frequencies I'd be the
most likely to find TP's on.

Are a stock DT-400W and a stock E100 even in the same league or fair
to compare to each other? I'm still thinking about getting one but I'm
hesitant because the MW on my E10 isn't that great. It was refurbished
so maybe that's why it was returned but it isn't aligned properly.
Gary has offered to have a look at it so maybe I'll let him. I guess
if I want an E100 I'd better get it while the single conversion type
is still available.

What type of batteries are you guys using? A friend says his SRF-59
isn't great with NiMH's but is really great with alkalines. I use
NiMH's in radios that charge them internally (Kaito KA1103 and E10)
and alkalines in everything else. Maybe my E10 would work better with
alkalines.

Thanks again to Gary for all of his hard work and imagination.

Hello Guys,

With a sudden rare chance to get away to Grayland, WA for an
early
morning of DXing on the ocean beach, I couldn't wait to try out the
three top
performers from the Summertime Shootout-- the DT-400W, a modified
E100, and
the tiny SRF-S84. I was especially interested in seeing how the
DT-400W would
compete against the previous "sensitivity king," the SRF-T615.

The SRF-T615 is an excellent, compact Ultralight, although
very pricey
compared to the DT-400W (about $120 including shipping compared to
about
$55). So how did these two perform in an actual DXpedition
environment? Well,
the two were similar on the low frequencies, and both could receive
JOAK-594,
JOIB-747 and JOUB-774 without too much trouble. HLCA-972 was slightly
stronger on the DT-400W, but not by much. But on the receptions of
HLAZ-1566 and
VOA Thailand-1575, the DT-400W was really superior, making
crystal-clear mp3's
of both stations (that the SRF-T615 had at a pretty weak level).
The stock
DT-400W was able to produce an mp3 of an ID from VOA-1575 (7,200
miles) that
sounded like a local, and I'll try to upload the recording to the
ultralightdx file section soon. The Sangean managed to receive 7
DX "countries" in one
early morning (Canada, USA, Mexico, Hawaii (KPUA-670), Japan, S.
Korea, and
Thailand).

My modified E100 has been logging weak TP's since June 29, but
it has
very fanatical sensitivity and selectivity improvements, so it's
not fair to
compare it to a stock Ultralight. During this trip to Grayland, it
received
North Korea-657, China-1593 and a presumed Taiwan-738, which would
be its 22nd
TP catch. Developed here in Washington state together with John
Bryant and
Guy Atkins, this extremely effective E100 will be the subject of some
upcoming technical DIY articles, so that everybody can have one of
these "secret DX
weapons."

The tiny analog Sony SRF-S84 was also a blast to use, managing
to log
its first TP with a reception of JOUB-774. When properly aligned
(for free, by
me), this ridiculously small Ultralight has performance that can
make even a
paltry propagation morning seem like an absolute blast.

If any of you feel like AM-DXing is not as much fun as it was
before,
just take a few top-rated Ultralights to an ocean beach... and
you'll be
shocked and thrilled along with the rest of us.

Hello Dennis,
 
     Thanks for your comments on your new DT-400W.  It's true that its sensitivity is great, but for somebody used to the selectivity of the analog SRF-59 and SRF-39FP units, it may seem somewhat more susceptible to local slop, as reported in the Shootout (B for selectivity, compared to A- for the SRF-59 and SRF-39FP).
In general, high-sensitivity Ultralights perform best away from urban areas, and especially well on isolated ocean beaches around sunrise :>)
 
     Of course I have a stock E100, and have tested it out extensively against the DT-400W.  The stock E100 has superior selectivity to all other Ultralights, and by a pretty wide margin when compared to other digital units like the DT-400W.  Unfortunately, the stock loopstick is a classic case of corporate cost cutting, in my opinion. With the flat loopstick skimping badly on ferrite, the low-band sensitivity performance of a stock E100 is pretty humble, compared to that of the DT-400W.  Even when the E100's loopstick is aligned to peak a 600 kHz signal, it will still come in a poor second to the DT-400W on all frequencies up to about 1000 kHz.  On the higher frequencies, the stock E100 becomes more competitive with the DT-400W until they are equally sensitive on the X- Band.  The E100's stock loopstick just begs to be replaced with a more sensitive Amidon 7.5" model, which is what the hard-core experimenters have done here in Washington state to create a super Ultralight.
 
     Having personally received multiple TP's on California beaches (using modest portables) while I was in the Navy at San Diego, I can assure you that propagation is certainly adequate on many days of the fall DX season.  Your challenge, Dennis, will be to find some frequencies where your local Santa Barbara QRM doesn't obliterate the weak signals.  The six TP frequencies successfully used by the DT-400W yesterday might be a good starting point (594, 747, 774, 972, 1566 and 1575).  If any of these are relatively clear in Santa Barbara, take your new DT-400W to the beach about 15 minutes before sunrise, face the NW direction, invert the radio (remember the little quirk mentioned in the Shootout), and listen for a weak-sounding signal in a language other than English or Spanish.  Each of these TP stations has its own programming identity, so if you hear any clues at all, feel free to post any questions.  I'm sure the TP gang will be extremely happy to help you, or anyone else with enough confidence and determination to chase TP's with stock Ultralights.  Good luck!

Hi Guys,
 
Conditions last evening started out rather blah with Transatlantics in early again but somewhat weaker. than previous evening. Then later on around 10 PM local time here things got interesting. Managed to log 12 more for the   Robert Ross 30 day challenge which brings the count to 191 stations after 5 days.
 
Bagged 2 new ones which included a new state,  Texas and another country , Tunisia. Logged the Tunisia station with the SRF-39FP completely upside down for the best signal nulling the local on 640 here allowing a clearer signal .
 
All other logs with the SRF-M37V.
 
 From 1600-1700 khz (extended band)  had been hard to dig signals out until last night also
 
 Some Logs from the evening  as follows:

Inside a G6 + Review Comments

John H. Bryant <bjohnorcas@...>
 

I had hoped that a modified E6, with its reported SSB capability, could serve as a spotting receiver for my hotrodded E100 on my upcoming adventure to coastal Peru. I now don't think that I'll take it, but I did learn quite a few things while modifying the radio. I've uploaded five photos to our Photo section that will give you a peak at the inside of a G6 and see my antenna mod, as well.

http://ph.groups.yahoo.com/group/ultralightdx/photos/browse/f619

Opening the set is no problem at all... two screws on the back and one in the battery compartment. What you get is a clamshell, connected together by a ribbon cable.  The upper board with the display and control circuitry (and speaker) stays with the top and the main board with the input/output jacks to one side, stays with the bottom.  I think that the main board is held in by those input/output jacks on one side and a single screw on the other.  I'm pretty sure that the plastic fitting where the ribbon cable meets the main board is NOT a pin plug, but just a hard-wire solder fitting to permanently attach the two boards together. I also would not be surprised if the main board is also glued in the back part of the case.  What I'm hinting at is my opinion that doing a filter change on this radio would be a NIGHTMARE....  so would any other mods to the main board.

Putting an antenna pickup coil on the ferrite bar was a bit of an adventure. The bar was held in with three blobs of hot glue which came out quite easily, but prying the bar up so that it could be worked on was really tough.  It turns out that there is a blob of really tough glue under each end of the bar, too.  I'd guess that anyone would have about a 50-50 chance of breaking the bar rather than getting it out. I finally raised one end far enough to put the pickup coil around the bar.  Since I could not get to the back side of the main board to attach the coil leads to the existing antenna jack, I used a continuity tester and found metal tabs on the outside of the jack that would connect to the two parts of the antenna plug (tip and braid).... after tacking the two leads to the antenna jack, it was just a matter of buttoning things up.  

I tested the new antenna input arrangement immediately.... sitting in my shack between two computers, the radio, barefoot, was wall-to-wall buzzes, burps and just a few stations, badly QRMed. I plugged in the outside antenna and things cleared immediately.... the "swamping effect" was alive and well and I could feed MW signals directly to the G6 from outside.  Success!!!

REVIEW COMMENTS
What I did not note in my brief look yesterday afternoon was signs of massive amounts of overloading.  I should have been looking for this, given Colin Newell's comments in his current review on dxer.ca about the 6 being too sensitive for use in urban areas. I really looked forward to testing the G6 this morning at dawn, with plenty of Asian split frequency stations, some that would be running S-8 or so. Man was I shocked and disappointed!!!!  First, there was quite massive overloading on MW.  It was so bad that the SSB detection basically wouldn't work.... the 10 kHz splits were pretty well smeared together and I don't know what else was going on...  The radio was not at all happy connected to the giant 70' x 100' Super Loop.  I had hoped to at least hear 774 and 1566 with the G6, since both were in the middle between 10 kHz stations and each was running S-8 or so when I tried.... there was nary a trace, even though there did seem to be a slight "gap" between each pair of 10 kHz. stations. All that I can figure is the massive amounts of RF coming in from the big loop was simply desensitizing the radio.  In any case, attaching a major outside antenna to the G6 for MW should only be attempted in the far Out Back, like Grayland, where there are no nearby stations.  I'm not at all sure how it would behave there, even.  I should add the front end was overwhelmed and there were ghostly and not so ghostly MW signals at least as high as 10 MHz on shortwave.Its really clear why the designers restricted the MW band to the small ferrite bar and not an outside antenna.

I suspect that the SW part of the radio would work OK on an outside antenna, without the ferrite bar loop that I added.... which is feeding massive MW signals to the front end.  I'll try that after I take the added MW loop out of the antenna circuit.

My biggest disappointment was the SSB capabilities of the radio.  I suppose that it is true that the G6 circuit will demodulate signals transmitted in SSB, though I did not look around on the ham bands for a SSB signal to try it out and I'm not sure.  It is true that you can zero-beat an MW AM signal using the slow tuning and true that you will understand the audio.  HOWEVER, I'll bet my entire pension that you are still listening to both side bands.... it ain't SINGLE SIDE BAND at all! Those of you old enough to remember DXing before SSB will no doubt recall listening to an AM signal with the BFO on. If you tuned to the center of an AM signal and then zero-beat (centered) the BFO over it, you could tune up and down the band hearing a descending whistle until you hit the center of a signal, and then the whistle would go right back up as you tuned past. Well, imagine that BFO fixed on the center of the AM frequency and unable to be tuned independently from the main tuning of the radio..... What do you have, then???   You have a frequency or carrier marker, but you are not able to select one side band or the other to listen to, to dodge adjacent channel slop, or dodge IBOC or whatever.  So the usefulness of the mislabeled G6 "SSB" is quite limited for an international MW DXer and non-existent for those who DX on domestic frequencies.

There are other limitations to the "SSB" detection system offered on the G6.  The "SSB" detection is clearly intended to be used with the slow tuning rate, which actually feels like slow analog tuning. It takes almost four full rotations of the knob to go one kHz. That's fine for clarifying a signal and none too slow, at that.  However, its useless for slow band scanning in "SSB" to detect international carriers.  You can use "SSB" in the fast tuning mode (a 1 kHz tuning step, when in "SSB.") That capability, if everything else worked as an international MWaver would wish, would be marginally useful.  The optimum tuning step would be 0.1 kHz, but the full kHz would be somewhat useful. Of course, the design of those other things actually work against its use as an international DX machine.

The "SSB" capability has one further nasty habit: When in Fast tuning mode (what you would use for Int. MW) the BFO seems offset about 300 Hertz to produce a garbled growl. I think that is so that you will know that you are in "SSB." You can then switch to Slow tuning and clarify..... HOWEVER, when you switch back to Fast tuning, it jumps back to the 300 Hertz growl!!!  It does that every time.  Unless my unit is defective, it is simply another example of the engineers dumbing down a circuit for the "convenience" of unsophisticated users. Grrrrr!

CONCLUSION
Since I've verbally stood on this radio and jumped up and down, I need to remind myself that these sets WERE NOT DESIGNED FOR DXing!!!  We are absolutely misusing these receivers from the designers' point of view. As Colin implied in his dxer.ca review, the G6 could be a really good set for the suburban or, especially rural person (too sensitive for many urban uses) who wished to program listen on shortwave or, even MW. Its a nice little radio with a superb strength meter and LCD for its size and pretty reasonable audio quality. That is exactly what the Eton/Grundig designers were challenged to provide, I would guess.

For the Domestic MW DXer, the plusses are 1 kHz resolution and the sensitivity (outside urban areas) and the minuses are a useless SSB capability (for DXing) and fairly wide selectivity. For the International MW DXer, the G6 is one of John Madden's four-drumstick TURKEYS. It is one of life's little ironies that the "SSB capability" that disqualifies this radio as an official Ultralight radio is so useless for DXing MW.    

There went $100 right down the drain!

FS: Sony SRF-T615 and Sangean DT-200VX with Filter & Antenna Mod

Guy Atkins
 

I hope it's OK to mention this on the Yahoogroup, but I'd rather sell the following radios to Ultralight enthusiasts before listing them on Ebay.
 
Since I use my Eton E100 and other larger radios almost exclusively now, and I'm not a collector of receivers, I have the following which need a good home:
 
SONY SRF-T615 
This is the over-achieving, tiny AM/FM radio that is typically available only in Japan. Until the recently introduced DT-400W came along, the SRF-T615 was the undisputed leader in stock AM sensitivity. The new DT-400W reportedly has a small edge over the SRF-T615. The Sony is certainly the *smallest* radio with excellent performance, though! This unit is in excellent, stock condition and works perfectly. It has also been recently aligned on AM. These radios are typically $115 + shipping from Japan, but I am selling this SRF-T615 for $55 including free shipping in the USA.
 
SANGEAN DT-200VX with upgraded 6 kHz I.F. filter & antenna mod
This receiver has been fitted with an improved 6 kHz filter, the Murata CFWS450HT. This filter is the same nominal -6 dB bandwidth as the stock one, but with a much better shape factor due to the 6-element design (versus 2-elements in the simple, Chinese-made stock filter). This DT-200VX is in excellent condition and works great. With the upgraded filter and careful nulling I'm able to catch DX signals within 10 kHz either side of my super-local KSUH (1450 kHz, 1.4 miles away from my home). This radio also has the desirable "external loopstick mounting", which gets the antenna further from the circuitry's noise field for noticeably better weak signal performance. The antenna is positioned approximately 1 inch below the bottom of the radio's case, using a Gary DeBock-approved mounting solution (a piece of a wooden ruler :^)  The DT-200VX has had a full AM alignment. $45 shipped in the USA.
 
Please contact me off line if interested in either of these.

Re: calculating distances

thank you Allen and Richard for the link to calculate distance from

drastic difference from the road mileage that most maps calculate but
can see its value for TA's or TP's.

In answer to your question I personally use Google Maps Distance

site http://www.topazdesigns.com/ambc/ it has very useful information
about power output  and antenna patterns also just with the input of

available on ebay from tquchina. The M-10 is only AM! And the RP-50
has "two" FM bands!

Off-topic: DT400W overseas / FM portable recommendation

huelbe_garcia@fastimap.com <huelbe_garcia@...>
 

Hi,

these are off-topic, but could help people:

. I found a Sangean DT400W with overseas shipping. To Brazil it costed
US$ 57.31 (product) + US$ 22.55 (S&H). This is the link:

http://www.tyrellelectronics.com/pc-146082-2-amfmaux-weather-alert-radio-dt400w.aspx

They accept Paypal. I've just ordered the DT400W from theirs, so I
cannot recommend this company yet (have to wait
until little yellow arrives here :)

. In the last two days we had incredible tropo conditions in South
Brazil, Uruguay and East of Argentina. Hepburn's tropo maps were just
perfect. Using a Grunding G5 (mine) and Degen DE1103 (friend's) we are
able to listen to 7-9 stations. It's really cool to listen to a
different language (spanish in this case) on FM!. Grunding G5, Degen
1103 and Kaito KA1103 (and maybe others) share the same very good FM
section. It was definitely better than Sony 7600G, Sangean ATS909 and
even Sony XDR-F1HD (with indoor antennas). So, if you need really good
FM on portable, go with G5 or 1103.

I have seen photos of this gray DT-400W but you better call and check
to make sure the radio they ship is in this color. I think perhaps
these photos were promotional ones by Sangean before they actually
produced the radio in yellow.

hihi, actually, I have difficult with some colors. The DT400W
pictured
above it's not a 'pure grey'. Definitely it's not black nor
a 'shocking'
color :)

Dear Paul,

Thanks for you comment on the DT-400W color.

When comes with color, it's matter of personal preference. The
outdoor
yellow color of DT-400W was requested by one of our big
distributors.
It's a sport/outdoor giant retailer.

Thanks Mark, it is much appreciated. Now I can program my receivers.
It been nearly two decades since I did any trans-oceanic dxing and
there have been some changes.

By the way, I discovered AM frequencies in the memory of the DT-400W
are cleared when changing between 9 and 10 kHz steps.



*** Same as the 200. Unfortunately one negative point from that they apparently didn't improve upon.
