The radio will probably run from 3V to 9V.

I have three Eton radios, E100, E5 and an E10. I had power supplies for the
E5 and E10, but I left one plugged into a power bar and the wires on it

came with either the E5 or E10, but is rated @ 8V DC output, the E5 and 10
are labelled as 6V DC input. Can anyone tell me if in can use this power

Re: Accumulating, Using and Storing ULR Pocket Radios when "NOT" using them...A solution found!!

Great post, Rob.

I might add one additional thing: Remove the batteries!!

I recently dug out a Garmin GPS unit that I wanted to see. Hadn't used it in a couple of years. Opened the back and found one of the AA batteries leaked all over the inside. Oh, man. And the battery wasn't even out of date. A short 2 years!

Four ultralights here. I have some catching up to do!

Hi Guys:

When the ULR Craze first hit back in Late 2007........I had only 1 ULR
Radio..that being a trusty little SONY SRF-59 that was sent to me as a
gift by the Grandfather of ULR Dxing...Gary DeBock. It wasn't hard to
store the radio.......it just sat wherever I last used it....until I was
ready to DX with it again.

Then Gary discovered that the Guys in the Penitentiary had been DXing
with something called "The Prison Radio"....aka as the SONY SRF-39....a
Clear Plastic Cased set that was much easier to tune than the
SRF-59......so of course I had to get one of those as well. Actually I
got 3 of them.....just in case one of them died!! Along the way I picked
up a couple more SRF-59's too. So now I had a handful of these little
critters.

Along comes the ETON E-100 a Digital Readout set with a lot better
features than the little Sonys. So of course I picked up one of those as
well. Then the West Coast Mafia of ULR DXing discovered that you could
attach a "Slider Coil Ferrite Rod" to the E-100 to make it even better.
So.......after begging and pleading Electronics Ignorance....Gary and
John Bryant built me an E-100 SLIDER....which I affectionately named the
"FRANKENSTEINER". This one is mounted on a board...and definitely won't
fit in your pocket.

I guess Gary figured that I still had some money left that I hadn't
spent so he went out and discovered a bunch of New ULRs....that had
surfaced in the first year of ULR DXing. The Sangeans, The Tecsuns, The
Grundig, the Kchibo...you get the picture. I was having so much playing
and DXing with these Little ULRs....that I was not conscious to the fact
that I was assembling a "STABLE" of Tiny Pocket Receivers.

I had them laying everywhere........In the Family Room, In the
Bedroom....even in the Bathroom!! HAHHAHHA......

As I type this message, I now have 19 Radios that qualify as bona fide
ULR's. Wait a minute....did I say 19 ULR's?????? Yup....I did. And
what's worse..there are some of you out there who most likely have MORE
THAN THAT!!! Right????
Back in the 1980's and 1990's I was Huge Collector of Antique Radios and
Microphones, and Tubes, and Communications Receivers....and pretty much
everything associated to OLD Radios! That included 1950's and 1960's
Pocket Transistor Radios from Japan, Europe and USA. At the peak I
owned almost 500 Pocket Transistors from the 50's and 60's. Had a lot of
fun collecting them too.....some were Mint New in the Box...others were
beat to %$#@...but were still very cool. Some worked.....some didn't
.,...but it didn't matter....they were all little works of art from a
long gone era.

About 10 years ago I decided to thin out my collections of Radio
"Stuff"....and all the Pocket Transistors were sold over a number of
years to make room and $$$ for other interests. Little did I know that
the Little buggers would come back to haunt me in the form of ULR Radio!!

Anyways....to make a Long Story even longer........I now find myself
with an ever growing "Collection" of Pocket Transistors
again.......except all of these work real well...and are technically
leaps and bounds ahead of the 1950's Transistors.

I'm a hopeless case when it comes to collecting Radios.......and I know
before long I will have 30 of these crazy little Pocket Rockets....and
who knows where it will end. As well as being hopeless in my collecting
........I am also generally a very organized person..and believe
everything must have it's own place.

That's where the "Storage" part of this message comes in. Instead of
having them laying all over the place.......I wanted to have a way of
keeping them in one place......out of the way.....yet close at hand and
easy to get at when I want them. I spoke to my wife who is a very good
Crafts person....and can make pretty well anything whether it's Sewn,
Knitted, Quilted, Built, Put together, or whatever it takes. I asked her
what I could use to solve my dilemma. She advised me she could make
something for me to hang on a door...with individual pockets for each
radio. It would hang on a door and be out of the way. All of the radios
would be right there in "ONE PLACE"....and it wouldn't take up any
room...the footprint would be virtually invisible. She also advised me
that even though she could make this ULR Holder for me....my best bet
would be to go to a store here in London, Ontario called "Solutions".
They sell virtually every kind of "Storage" container, Holder,
Organizational System you could possibly envision. They had a Canvas
Shoe holder with just the Pockets she had described.......enough pockets
to hold 12 Pairs of shoes......or 24 ULR RADIOS!! VOILA! That solves the
problem for the First 24 ULR's anyway!! The Price was right...it was
$15.99 on sale..is very well made and looks great. It is made of Cream
Coloured Canvas. If I get more ULR's...I know where to get another
one.....and it can hang on the other side of the door in my Radio Shack.
Not only do I have the 19 ULR's all resting in their own little pocket
........I have a few pockets left over for Cases, EarBuds, and other ULR
Accessories!!

I'm sure every major City has a store similar to the "SOLUTIONS" store
here in London. They had several different styles of Shoe Holders...but
this 24 Pocket model gave the most bang for the buck...and solved my
"Where the Heck do I keep all these things dilemma".

I'm sure there are other ways to store ULR's...Boxes, Drawers, Cabinets,
and of course "All over the place"...like I was previously doing!! This
works for me........your mileage my vary!!

I'll take a digital photo of this thing...and see if I can figure out
how to Post it in the Files Section....so you can see how it looks.........

If anyone else has a better idea how to store ULR's when "Not" using
them...please let us know......

What Gives Here?

Kirk Allen <kirk74601@...>
 

I just tried to post a correction/retraction, and it didn't show up. Well, I'll try once again even though I'm pressed for time.

After confering with Richard Allen about one of the loggings just reported, he says, "I hate to dampen things, but your "ESPN 710 AM" catch was possibly KXMR, Bismarck ND. Their web address is www.espn710am.com. I was hearing CKRM at about that time. I've yet to hear KXMR myself."
Well KXMR is a relog for me, and with Richard's knowledge, I'm removing the logging of KSPN on 710. I apologize YET AGAIN for the correction. One way to stop making mistakes like the ones lately are to never really seriously DX, so you can bet I'll make more mistakes in the future!

Tecsun PL300WT first thoughts

Paul Logan
 

Hi all,

received my PL300Wt this afternoon and what an impressive little radio it is.

FM is great with selectivity as good as some of my unmodified tuners.

AM sensitivity seems to be about as good as my tecsun R911 which has been aligned.

I've given up on trying to align the new radio as I simply cannot get the coil former to move on the ferrite rod inside.I removed all the wax I could and its still not going anywhere. being fearful of doing some damage to the winding I have given up. Will see how it works at sunset and after dark.

The FM performance alone makes this one a keeper and with coverage down to 64 mhz it will be very interesting when theres some E skip around - wish I had bought it before the summer.

Anyone else have major problems getting the coil former to move in this radio? Is there much to be gained on alignment with this model? I may well use it with loops anyway.

regards

Paul Logan,
Lisnaskea, N. Ireland

8-9 Grayland Ultralight DXpedition-- New Zealand Booms In

Gary DeBock
 

Hello Guys,
 
Several MP3's from the August 9th Grayland (WA) DXpedition have been uploaded to the sound file site on the Yahoo Ultralightdx site, and to the Sound Bite section of http://www.dxer.ca.
 
With extremely strong propagation to New Zealand and Tahiti, MP3's of 648-NZ Rhema (Gisbourne, NZ), 675-3YA (Christchurch, NZ) and 738-Radio Tahiti were recorded, using both a new Kchibo D96L DSP-enhanced ULR, and a C.Crane SWP 7.5" Slider model. The radios were greatly assisted by a 36" square collapsible-frame tuned passive loop, which was designed and built in a crash program shortly before the trip (since it was the largest antenna that would fit inside a fully loaded Toyota Corolla trunk, during a family vacation).
 
Also, for those interested in the newest selectivity champion in the ULR class, a comparison MP3 of the Kchibo D96L's 1 kHz DSP performance relative to the premium $50 Murata CFJ455K5 filter has been uploaded to the Ultralightdx file site. Comparing the reception of 567-2YA (Wellington, NZ) in the shadow of strong domestic KVI-570, the first 20 seconds of the MP3 were recorded on the new stock D96L, while the second 20 seconds were recorded on the C.Crane SWP Slider, with the transplanted CFJ455K5 filter. To equalize signal levels, both radios were assisted by the 36" passive loop. For those of you desiring highly competitive selectivity performance in a stock $58 Ultralight radio, the result should be very encouraging!
 
A full report of the 8-9 Grayland DXpedition (and the multiple new Kiwi loggings) should be finished shortly.
 
73, Gary DeBock (in Puyallup, WA)
 
 
      


Re: Two New Articles on the Kchibo D96L DSP Ultralight Uploaded

Guy Atkins
 

Hi John,
 
I'm glad you found the same thing as I did about the even response of the D96L. I spent a frustrating hour last week trying to locate the rumored "sweet spot" on these DSP portables that have the Silicon Labs chip! Like you, I also used a signal generator  and observed the dBu readout on the radio to to try and "align" the coil (both stock and my Amidon ferrite rod replacement). Nothing seemed to make any difference. Signal levels were steady across a wide inductance range.
 
This characteristic of the D96L is another reason besides the filtering, 1 kHz tuning resolution, and 9/10 kHz step size which will make this radio a no-brainer choice for many ULR enthusiasts.

Welcome to All Our New Members Except Rippel

John H. Bryant <bjohnorcas@...>
 

Welcome to all of our newest members!!!  We broke the 300 member barrier yesterday. That is kind of hard to believe. We founded this e-group in late March, 2008 with about 30 members in the first few days.   This was just three months after Gary DeBock accidently discovered Ultralighting by catching the first TP stations (Japan) using a Sony SRF-59, barefoot.  The rapid growth of this niche of the radio hobbies is partly laid at Gary's door - in his excitement to share the shear joy to be found in Ultralighting, he was a shameless and most generous booster in the early days. There were times when his co-dependant friends feared that he might appear on Facebook in one of those skimpy American football cheer leading outfits, complete with hand-held pop-poms! Since Gary's early boosterism, a lot of us have joined him in helping each other grow in this part of the hobby. Most of us have spent years (decades in many cases) in other branches of the radio hobbies. Its really been fun to watch as various of us have applied lessons learned in those other hobbies to the growth of Ultralighting.

Ultralighting is both Infectious and Addictive!

For those of you who have not yet done so, check out the Ultralight Library! There are currently about 75 articles of use to Ultralighters that reside in the Library.  There are two mirror images of the Library, one in the Files area at DXer.ca (Colin Newell's excellent site) and in our own Files section here at yahoo's ultralightdx. The easiest way to get to the Library here is just to click on the Files hyperlink at the bottom of every ultralightdx message.  The articles are organized by subject in folders and are downloadable/printable.

Oh, and the mention of "Rippel" in the title of this note???  I just wanted to cause a bit of anguish to my long-time friend, Chuck Rippel of Virginia Beach, Virginia. Chuck has been a leader and major contributor to many aspects of the radio hobbies for decades. Many of you will recognize Chuck as the leader of the reorganization of a lot of NASWA in the shortwave broadcast DXing hobby in the 1980s and early 90s; others of you will recognize Chuck as the absolute guru of R-390A restoration/reconstruction, or you may know of him from his long involvement in the world of amateur radio. Anyway, its wonderful to have Chuck join us here at ultralightdx... Chuck, you will recognize a lot of names from the past and, delightfully, meet a lot of other cool new friends. Now that you are here, lets start seeing loggings and articles, by golly. Do you realize that it would take well over 100 ultralights to weigh as much as one R-390A???

To me, audio recovery is the jewel in the crown. Have used many radios that in no way recover as much audio as proportional to carrier. SDR receivers are the exception.

That all said, many of the ultra lights are not SDR so any work one can do to facilitate audio recovery carries as much weight as improvement in signal level.

Thanks for the heads up on the chip. I may build out my Sony 59 like John did and if so, may add one of the audio chips to it to "ice the cake."

Hi Kevin and Chuck,

Head-fi.org is one of my favorite Web sites. I've learned a lot about
headphones, interconnects, amps, and related equipment there.


Re: Grundig G8 With and Without Homemade Ferrite Loop Antenna

Gil,

I got your message. Sorry I haven't responded sooner, but my son just turned eight, so I needed to spend some time with him (on his new skateboard. I am working in my classroom this week, so I don't get to the computer as often as usual. Classes start soon, and things will get back to normal.

I've been working on some ideas in my mind today, so I'll email them to you.
You've spurred some good ideas on my ground setup.

Two New Articles on the Kchibo D96L DSP Ultralight Uploaded to the Library

John H. Bryant <bjohnorcas@...>
 

Friends,
 
I have just created a separate folder under "RADIOS" in the Library (Files section) for articles about the new D96L DSP Ultralight from China. I've also uploaded two short specialty articles detailing my recent work with this soon to be popular ULR.

The first article is "'Alignment' of the Kchibo D96L"  As you may know some of us have discovered that the G8/PL-300WT DSP Ultralight does actually benefit from "aligning" the ferrite antenna coil to find the sweet spot where AM performance is maximized. Since those receivers and the new D96L all use the same chip as their hearts, we assumed that the D96L would also require "alignment." IT DOES NOT!  Here is the concluding paragraph from that article:

Conclusion  
Unlike the G8/PL-300WT, the Kchibo D96L appears to be able to achieve maximum AM sensitivity over a wide range of coil/ferrite bar inductance values, between 250 uH and 1000 uH in the unit tested. Given that the factory antenna provides somewhere around 420 uH in its fixed stock position, there appears to be no point whatsoever in attempting to align the stock D96L. Gains in weak signal sensitivity will only be achieved by external means (adding a large ferrite bar, an inductively coupled loop or connecting to an outside antenna, etc.) This is a very important finding, since it means that enthusiasts who purchase the Kchibo D96L may be assured that their receiver is already operating at maximum sensitivity.
 
As you may know, the D96L is almost unique among Recognized Ultralights in providing switchable IF filters.... in this case, FIVE switchable filters. The second article, "Kchibo D96L Filter Response Tests" discusses tests that I just completed on the filter responses at each setting. Here is the conclusion to that article:

With my Kchibo D96L, when I switch through the filter settings of 1,2,3,4,6 kHz, I actually invoke the 1kHz, 6kHz, 4kHz, 3kHz and 2kHz. filters in that order. It now appears that this filtering pattern exists on every D96L received so far in our Ultralight enthusiast group.
 
If you would like to read narratives and view the test results for yourself, the two articles are in the Kchibo D96L folder of the RADIO folder in our Library.
