Hello Carl,
 
     Although I am not a member of the Ultralight Definitions Committee, their definition guidelines for Ultralight radios affect all of the activities of the Ultralight enthusiast group, including the upcoming 2008 Summertime Shootout. 
 
     You are correct in that radios with built-in mp3 players, cassette recorders or other peripheral devices are not currently being considered as qualified Ultralight radios, as defined by the Committee.  As such, the contenders in the Summertime Shootout will not include such "combo units."
 
     However, externally connected audio recorders are perfectly acceptable for any Ultralight radio, as well as externally connected speakers, batteries, antennas, etc.  Such external attachments may place the radio in a "modified" (non-stock) status for competitive purposes, but will not affect the qualification status of the attached Ultralight radio.
 
     Thank you for your question, and for your interest in the upcoming Summertime Shootout.
 
                                                                                           73,  Gary

Re: Possible Contenders for the Ultralight Radio Summertime Shootout

Hello Dave,
 
     Thank you for your suggestions of the GE #7-1637A radio, and the Sony WM-FS493 radio-cassette combo unit, for the Ultralight Summertime Shootout.
 
     As you may be aware, the rules for shootout "contenders" are very close to the rules set by the Ultralight Classifications Committee for Sprint contests, and for competition for John Bryant's List of Firsts and Records.  Basically, this means that possible contenders must qualify as an Ultralight radio (as defined by the Definitions Committee), and must be generally available for purchase (as new units) by interested AM-DX hobbyists.
 
     In some instances, such as the E100 and SRF-39FP units, there is a constant possibility that approved but discontinued units may no longer be available for purchase, but once the model is approved by the Committee, the model's qualification will almost certainly be "grandfathered" by the Committee, for future qualification.  Otherwise, the Firsts and Records List would need to be altered each time an approved unit was unavailable for NOS purchase on eBay.
 
     As you may be aware, the Classifications Committee has issued a general guideline that radios in combination with peripheral devices (cassette recorders, cameras, mp3 players, etc.) are not currently being considered as qualified for Ultralight Radio designation.  This guideline is also being observed for qualification as an Ultralight Radio shootout contender.  Radios that follow the definitions guidelines set by the Committee AND available for new or NOS purchase by AM-DX hobbyists will be considered for the Summertime Shooutout, although if the units are not generally available from eBay or other common sources, they may fail to qualify.  As such, your suggestion of the GE #7-1637A model will be accepted if the radio can be purchased from eBay (or other common sources) as an NOS unit.  The reason for this requirement is so that interested hobbyists can easily order any shootout contender they desire, rather than face the frustration of tracking down a rare discontinued unit.
 
                               73,  Gary DeBock

Thanks for the heads up on the Stormwise Site. Although off of the ultralight topic, I was wondering if one of you "experimenters extraordinaire" had looked into a monster ferrite bar for an Eton E1, thereby addressing one of that fine radio's shortcomings? Considering the reports of the results of that approach with a 2010, one of those large ferrite loops should be awesome on an E1. Thanks for all of the "thinking out of the box" and experimenting on the ultralights and the 2010. Your efforts have made the hobby even more interesting. Now, if I could only duplicate coastal conditions this far inland. Hi!

Hopefully the Stormwise 1.0 X 16.8" rod has shipped by now. I was told that it would be "3 or 4 days" until it shipped, as he needed to construct the rod inside the thin, protective plastic tubing he puts all his ferrites into. I'm not doing any loopstick work until this biggie one arrives (I don't have any Amidon rods now anyway; just some vintage ones.)
 

I finally googled the stormwise site, Guy.... very impressive.  I can't wait until you have your big bar onna E100 and compare it to about the same length Amidon half-inch dia. bar of about the same length with Gary.  As I understand the theory (and I'm not sure that I do) The 1" stormwise ought to be twice as sensitive to 4 times as sensitive per inch of length.... were the ferrite mix the same.  REALLY going to be interesting to compare them. I was impressed with several things on the Stormwise site, but especially his prices for big ferrite bars.

http://www.stormwis e.com/



Please refresh my memory: do I need to take an inductance reading of the STOCK loopstick on the E100 while it's in the "peaked on 600 kHz" position? I take it that this value is what I shoot for with the new Litz wire coil on the big ferrite rod.
 

That is what Gary and I did. We peaked it up at 600 kHz. and then measured the inductance (mine was 250.3. His was somewhat higher.) We then created coils that matched that inductance. I positioned my test coil halfway between the center and the end of the bar as I took off turns to hit 250.  The nearer the end of the bar, the lower the inductance and resonant frequency... nearer the center, the higher the inductance and resonant frequency.

Also, John & Gary, what is the linear distance on the ferrite rod between the peaked at 530 kHz and peaked at 1700 kHz? Are we talking fractions of an inch between the two sweet spots?

Surprised me with the distance needed to travel.  My sweet spot at the low end o the dial is about 90 percen of the way to the end. The high end sweet spot is nearly in the center... That is with the .5" x 7.3" Amidon bar. The fatter bar ought to change inductance of the coil more quickly ????


 
John, I was surprised your E10 did so poorly in your tests today. Mine has not been tested carefully, but my impression is that it is close to the DE1103 in sensitivity.
 

Yes, I was surprised, too. I'm going to have to try to align that thing and try again, only A/Bing with the E100+Amidon 7.3" They should have ben more competitive. I don't want to give up on the E10.  Given the quality of the E1 and the E100 on MW, I just can't believe that the E10 issa turkey.

E100 Notes + Stuff

John H. Bryant <bjohnorcas@...>
 

Gary, Guy and I continue to work on hotrodding out individual E100s in various ways. In conjunction with that effort, I had an informal shootout this afternoon amongst all of my Ultralights  that don't rely on exterior wire antennas. I also threw the Eton E10, the big brother of the E100 into the mix.  I started out with a totally Barefoot E100 as base receiver. It had been aligned but that is all. It was fairly sensitive on MW, top and bottom and did not overload in the RF cesspool on far suburban Vancouver, BC, where I live.

I was using a homebrew audio switching device that allows me to compare the audio from two receivers, one in each ear, or have the audio from one of the two receivers in both phones. I first compared the stock E100 to an aligned barefoot SRF-39FP. The SRF-39 was a bit more sensitive at both the top and bottom of the band. '39 also seemed to be slightly more selective, though that was harder to discern. Of course, the E100 was ever so much easier to operate, etc. I then compared the SRF-39 to a DT-200VX with an upgraded filter.  The SRF-39 held its own in sensitivity, but GUy's new filter in the DT-200VX gave it the nod.

From there, I went to the newer (to me) radios and also used my 1" x 12" Booster Bar with the T615 stock and my DT-200vx.  The three newer radios were the barefoot E10, an SRF-39FP with an Amidon .5" x 7.3" ferrite bar and new coils out of 40/44 Litz wire,  and an E100 with a similar Amidon bar and new coil, but this time, with the coil able to slide on the bar to "align" the radio on each station for optimum performance.... a new strategy that Gary sort of discovered and I adopted even before he got his built :>)

The notes:

E10: The E10 is far too large to be an Ultralight, but I was hoping it might be competitive enough with the E1 that I could consider taking it overseas instead of the E1 in future travels...  It is about 4 times the size of the E100 but only 1/8th the size of the monster E1. Frankly, on MW, the E10 is a piece of trash as a DX radio.... at least in this RF-heavy environment. Its selectivity was pretty awful, actually very noticeably worse than the E100!!! And it was fairly insensitive, too boot. I was very disappointed. This was a unit which has not been hand aligned and maybe that will improve sensitivity, at least some.  It should be amenable to inserting the wonderful narrow filter from the E1 and that may (should?) improve the selectivity quite a bit.  I'm glad that I bought the radio (at close-out prices), so that I have one example of each of the Eton Elite original series (E1, E10, E100) but mine sure was awful in today's test.

SRF-39FP: This unit was fabricated by Gary and is a very hot performer with its new Amidon ferrite bar and new larger diameter coils. It was the second most successful set of the afternoon. There was no noticeable overloading, but tuning required safecracker hands and it also placed second in selectivity to the E100.  One of the more telling tests was hearing KPOJ-620 in Portland, which puts in a fairly weak daytime signal here that is nearly swamped by the CKBD-600 Flamethrower here in Vancouver and KCIS, Edmonds, WA a 5KW station about 50 miles of mostly seawater to my south. With the most careful of tuning I could hear KPOJ audio in one spot with the hotrodded SRF-39FP..  The level was enough for language recognition, but following the program was impossible.

E100:   The E100 with a 7.3" Amidon bar and the coil arranged so that it could slide was noticeably more selective and sensitive than the SRF-39FP. The differences were significant and somewhat unexpected (see the barefoot comparison above.) The sliding arrangement increases the sensitivity throughout the band, so I expected that the peaked-up E100 might be the same or better than the '39 at the upper 2/3 of the band. However, I did not expect  the E100 to be better than the '39 down low around 600 kHz. Afterall, the '39 was low band aligned at 600kHz and should be peaked up there.  Instead, the E100 was head and shoulders above the '39 in the KPOJ-620 test. The KPOJ program on the 100 was easy to follow... a little scratchy and with a few vestiges of splatter, but ever so much better than on the '39.  Even though I don't think that the slider coil had anything to do with that reception, over all, it sure made the little E100 into a DX Animal!

My tests were not nearly as formal as Gary's Official Shoot-outs and the findings may well vary somewhat (tho' my money is literally on the E100... I just bought another this evening, making a total of FIVE E100s here.) I'm really glad that Gary is going to do a Summer Shoot-Out.  Enough things have changed since the last one (especially the E100, IMHO) that his services are badly needed before the Fall.

Oh, I forgot to mention the tests with my 12" Booster Bar.  I put a Barefoot E100 on the booster bar and it was no where near as sensitive as the Amidon-equipped one discussed above.  Also, the T615 was not a success in this RF-rich environment when used with the Booster Bar. It overloaded some and just generally misbehaved.  I'm unsure whether my Booster Bar is just a poor one or whether none of them can compete with a new Ferrite bar by Amidon, transplanted right into the receiver circuitry.  I've more comparison work to do there, but I doubt that booster bar will be in my line-up in the fall.  The E100 with an Amidon bar (or maybe three Amidon bars) darn sure will.

In any case, it was a great way to spend a sunny Sunday afternoon on the deck, with light breezes and temps in the mid-60s.

Have a great week!

Re: E100 Notes + Stuff

Gary DeBock
 

John,
 
     Your "Amidon E100" and "Amidon SRF-39FP" daytime DX shootout was also tried here, with similar results.  The "sliding coil" trick improves the sensitivity of the hot-rodded E100 from modest to magnificent, and it also gives it an extra edge in selectivity, when the loopstick coil is peaked on each desired frequency.
 
     The hot-rodded SRF-39FP is a very sensitive performer, but without some help in selectivity (a challenge because of the 50 kHz IF), it has trouble splitting off the 9 kHz signals at Grayland.  Presumably, a "sliding coil" trick could also help the SRF-39FP, at least on the lower frequencies.  But I doubt it would improve selectivity to the point where it would be competitive with the hot-rodded E100, since its aligned loopstick frequency (600 kHz) is almost the same as the 620-KPOJ frequency, where it failed your selectivity test.
 
     Guy's premium 455 kHz IF filters may be almost the last thing the modified E100 really needs, to shine at Grayland.  That, plus a shotgun-barrel sized composite loopstick should do the trick  :>)

Ultralight Radio Summertime Shootout

Gary DeBock
 

Hello All,
 
     Prompted by many requests for a comparison of the Eton E100 with other top Ultralight radios, and also the interest of many DXers in the new Sangean DT-400W model, a full review of these and other pocket radios is scheduled for this summer.
 
     The other contenders (already on hand) are the Sony SRF-M97, and the Sony SRF-S84.  If any AM-DXers would like to suggest other pocket radios for consideration, please do so without delay.  As in previous shootouts, "contenders" should have competitive AM sensitivity and selectivity, and are subject to elimination before the competition, should they fail to perform at an acceptable level.
 
     Following the format of the January 2008 Shootout, the top surviving contenders from the previous competition (the SRF-59/39FP, SRF-T615, DT-200VX, DT-210V and SRF-M37V) will be judged against the current contenders during the live signal competition, for ultimate Ultralight DXing glory.
 
     A very extensive record of quality control data (and modification potential) has been collected since the January shootout, so this additional information should prove very useful to any interested pocket radio DXer.  Thanks again to all who have made Ultralight Radio DXing such a great success, especially to the 51 members of the Ultralightdx Yahoo Group site.

Re: DT-200VX vs.E100 Comments

Gary DeBock
 

Mark and Others,
 
     E100 experimentation here has already produced models significantly more sensitive than a stock 2010, but we (John, Guy and I) are attempting to create radios with both sensitivity and selectivity improvements, which will be capable of receiving multiple DU's on ocean beaches this summer.
 
     Receiving DU's on Ultralights is a tough challenge, because not only are signal levels generally weak, but the directional bearings are usually in-line with Seattle and Vancouver adjacent QRM, making it impossible to null the locals.  It's almost the same situation as you described a few months ago, referring to QRM from NYC and other semi-locals, as you chase TA's in Massachusetts--  only in this case, the DX is much weaker.  John was able to log multiple DU's at Grayland with his directional Wellbrook array hooked up to an E100, but for stock Ultralights, the DU action has been rare indeed.  Last Sunday at Grayland I was able to barely hear audio on 738-Tahiti on an SRF-T615, and on April 20th, had unID audio on 531 looping in the DU direction.  But the tinkerers here in WA are looking for a lot more than that, hi.
 
     In about a month or so, Mark, it should be clear how successful we will be, in creating the "Ultimate DXpedition Ultralight."  Assuming there is progress, I would be happy to modify an E100 for you, although it would be primarily for fun, not $$.  We hope many more highly successful DXpeditioners like yourself will take up the challenge of Ultralight TA chasing, especially if the E100 can be hot-rodded into a "dream machine."
 
                                                                       73,  Gary

Re: DT-200VX vs.E100 Comments

I too went for the E100 deal from Fry's (price a bit over $40).

My house interior is so riddled with RF digi-hash that I couldn't
really give it a fair sensitivity test yet. I'll have to take it
outdoors during the day over the weekend.

I have also noted the 1 kHz high readout quirk. A station on 1030
sounds best on 1031. Furthermore, selectivity seems sharper on the
lower side of an AM signal than when you go higher in frequency.
Roll-off 2 kHz below the apparent center occurs about as you would
expect it: the higher frequency audio gets scratchy and splatter-
like. But going 3 kHz above apparent center, perfectly readable
audio can still be had. At some point (about 2 kHz above center) it
actually sounds more muffled and bassy rather than the expected
scratchy / trebly sound that typically occurs when you tune to the
side of an AM signal. This just seems weird to me and makes me think
that something besides the center frequency readout accuracy needs to
be aligned.

In general I think the receiver has possibilities and, since I have a
number of other ultralight and semi-light portables, I'd consider it
a good "guinea pig" to send out to Gary to have him rework for a
larger external ferrite rod and to do whatever other magic he may
wish to perform (for a fair price) to turn this thing into a DX
machine capable of beating a stock Sony ICF-2010 or ICF-S5W, at least
in the sensitivity department.

Hello Paul (and John, Rob and others),

I'm glad you enjoy using your new E100, Paul. The 200 memories
and 1 kHz digital tuning steps give this model an edge over other
Ultralights, as proven by John's reception of multiple DU's, while
hooking it up to his Wellbrook array at Grayland. Even for casual
DXers, it has many superb capabilities.

The E100 just barely missed the cutoff for the 2008 Ultralight
Radio AM-DX Shootout (published on dxer.ca in February), so its
relative capabilities were not closely investigated at that time.
Because of that, and because other capable Ultralight models have
been "discovered" since February, a "Midsummer Ultralight AM-DX
Shootout" is seriously being considered (if there is sufficient
interest). This would compare the E100 and other new "contenders"
with the top models from the February shootout (SRF-39FP/59, DT-
200VX, SRF-T615, DT-210V, etc.) in the same format as the February
shootout, now posted on dxer.ca. What do you guys think?

John is correct in that 3 Washington state tinkering fanatics
are making 3 different E100 hot-rodding designs in 3 different,
bizarre ways. May the more reasonable, mainstream Ultralight
enthusiast group have mercy on us.

73, Gary


G6 Aviator

lrdheat
 

Hi folks,

 

I have the new Grundig G6. It is the same size as the E100. It has ssb which I guess disqualifies the set from the ultralights (although it cetainly is "ultralight"!).

 

In any case, I find that it is superior to the already fine E100 in selectivity and avoidance of overloading. Sensitivity seems similar. There is some noise on 1 or 2 frequencies...this is the case on 740 KHz on my set. At night, the noise on 740 does not pose much of a problem. The G6 has a larger "disk" knob than the E100's side of the case knob. It tunes very smoothly with zero muting. 1o KHz or 1KHz steps can be chosen. Like the E100, the display reads 1 KHz too high (to correctly tune in 770 KHz, for example, one would tune to 771). Although the ssb tunes in small pll controled increments, ECSS tuning is not very do-able. There is no USB or LSB which defeats the lure of choosing USB or LSB ECSS listening to rid oneself of qrm from an adjacent frequency.

 

On sw, it is quite sensitive on it's little whip, and amazing for such a tiny unit. On 20 meters, I heard both sides of a qso between Costa Rica and Corsica, New Zealand and Connecticut, and Zacatecas, Mexico and Chile in just the last 4 days!

 

It's a nice set, even if it can't be used as an ultralight for mw (even though, again, it is ultralight!).

Re: DT-200VX vs.E100 Comments

Guy Atkins
 

Hi Dennis,

I have owned a E10 for a while, and today received a couple of E100s that
were display models (got 'em for a song). I believe John Bryant has the E10
too..and we both have the big brother Eton E1.

I also got my E10 from Fry's for $30, and I really like the IF shift
feature, mainly because it means there is a 455 kHz filter inside, easily
swapped out for a narrower, better filter! So many of the small portables
these days have the tough to find 450 kHz IF filters.

So far I've been happy with the stock performance of the E10 on MW, but its
somewhat behind the DE1103.

73, Guy

Does anyone here own both an E100 and an E10? I bought a refurb E10
for $30.00 (that's not a misprint) from Fry's and am quite happy with
it; especially with the IF shift feature. From what I'm reading they
must be about the same on MW. Mine's not as quite sensitive as my

The E10 is too big to qualify as an ultralight. I wouldn't pay list

I could not be happier with my new radio. I paid about $40.00 from
Fry's.

I was looking for a digital radio that I could use for the ULr
Sprints, use for MW DX every night as I fall asleep and take with me
when I travel (so I needed a small battery powered radio with no
external antennas).

My other ULr is a Sony SRF-59. While I really like the 59, I wanted a
digital radio to better compete.

In the Sprints I feel that for the barefoot class you should not have
to use a spotting radio. The E100 is more than capable of being used
stand alone for any Sprint.

If you look at the last Sprint, it was a Sony SRF-T615 that won the
barefoot class and a Sangean DT-200VX (modified with a booster bar) in
the Unlimited class. I wanted a radio that I could use barefoot with
the qualities of both the 615 and 200.

I think I found it in the E100 at a cost below either radio.



Thank you,

Re: DT-200VX vs.E100 Comments

Gary DeBock
 

Hello Paul (and John, Rob and others),
 
     I'm glad you enjoy using your new E100, Paul. The 200 memories and 1 kHz digital tuning steps give this model an edge over other Ultralights, as proven by John's reception of multiple DU's, while hooking it up to his Wellbrook array at Grayland.   Even for casual DXers, it has many superb capabilities.
 
     The E100 just barely missed the cutoff for the 2008 Ultralight Radio AM-DX Shootout (published on dxer.ca in February), so its relative capabilities were not closely investigated at that time.  Because of that, and because other capable Ultralight models have been "discovered" since February,  a "Midsummer Ultralight AM-DX Shootout" is seriously being considered (if there is sufficient interest).  This would compare the E100 and other new "contenders" with the top models from the February shootout (SRF-39FP/59, DT-200VX, SRF-T615, DT-210V, etc.) in the same format as the February shootout, now posted on dxer.ca.  What do you guys think?
 
     John is correct in that 3 Washington state tinkering fanatics are making 3 different E100 hot-rodding designs in 3 different, bizarre ways.  May the more reasonable, mainstream Ultralight enthusiast group have mercy on us.
 
                                                                       73,  Gary

Hi John,

Along with an SRF-39FP,  I also have an E100 and have to say that it's a great little radio!  I like the digital tuning and the 9Khz/10Khz modes.  I'll be interested to see your hot-rodding  "How to" pages when you get them up on the web.

If you ever get interested in tinkering with this little gems, the E100 is perfect and easy to hot rod in a number of different ways. Gary DeB, Guy A and I are going crazy doing all sorts of semi-obscene things to our E100s. We are planning a series of two page "How-To" articles to start in the early Fall./

Personally, I'm convinced that the E100 will be the Ultralight Digital Classic, just like the SRF-39 family is for the analog sets.

Glad that you took the plunge!

Yes, Paul, the E100 was accepted by the Committee as an

Greetings Everyone,

Last evening (around 0000) UTC),I was walking around the kitchen here
in the apt., and then I stepped outside to check for a MW station ID. I
noticed that every time I got within a few feet of the telephone
connection box out back, I suddenly started getting a huge amount of
increased signal strength and clarity on any MW station. I'm seriously
thinking about trying to tap into this. After all, the box clearly
says "customer access" and is only shut by one little screw. I'll let
you know what I can find out on this as soon as I have the time to mess
with it. Obviously this isn't illegal because there's not a lock nor
seal on the box like there is on our typical electrical meters here. My
main concern is that it may overload the E-100 or the SRF-59. You guys
ever had this experience before?? I don't know for sure, but I might
accidentally be onto something pretty good here. Will try this tomorrow
and get back to you all on it.
