Hi David:

I just ran a quick test, putting two turns of wire as a sense/pick-up coil around the far edge of the crate (in the picture in Step 3 of the instructions, the two turns are in the channel on the far left of the picture). I terminated it with an RCA plug, assuming about 50-75 ohms, and ran it straight into my Yaesu FRG-100B. I also did an A/B comparison with my Quantum Loop. The results were surprisingly good! While the Crate Loop was typically running about 5-10 db lower than the Quantum Loop, the received signal on the Yaesu FRG-100B was the same, if not a little better, so that extra 5-10 db appears to be simply the amplifier in the Quantum Loop. Since it was about an S-7 or S-8 anyway, the amplifier was not really doing anything of benefit, so the two turns on the Crate Loop appear to yield the equivalent of a Quantum Loop! This makes sense, since the capturing power of the rather large air-core loop on the Crate Loop is certainly the equivalent of the much smaller coils within the Quantum Loop head, even with the assistance of a ferrite bar. The Litz coil and ferrite in the Quantum Loop head is about the same as that on the Slider e100, and since the Crate Loop really helps the Slider e100, it should also compete well with the Quantum Loop. It appears to be important to put the two turns for the sense loop at least a couple inches away from the main loop coil, since wrapping the sense loop right in the middle of the main coil yielded poorer results. You can see this with holding an SRF-59 to the Crate Loop - if you get too close, the tuning sharpness goes way down. Thanks for the idea, David - looks like an update to the Crate Loop instructions is in order! Kevin Thanks Kevin. I haven't soldered in years but could probably manage |

Kirk Allen has also been doing some testing of a Barefoot
E100 vs a Slider E100 vs a Slider + A Small Passive Loop (Select-a-Tenna
and others) His preliminary findings (article to follow soon) are very
much aligned with Kevin S's results.... Slider E100 is great by itself,
Slider E100 + Loop is even better! Like Kevin, all of Kirk's
testing has been on domestic channels.

Thanks for sharing your fantastic antenna design. If I build one, I think I'll add vernier tuning. My arthritic hands don't work well without it. Have a great DXing year. Richard Allen 36°22'51"N / 97°26'35" (near Perry OK USA) |

Thanks so much for your excellent Crate Loop article.... Well done and a great idea. I wonder, would you please append these tests to the article on DXer.ca??? Everyone with a Slider or similar hot portable is going to ask "is this simple/cheap project really worth the time/effort???" Your tests answer with a resounding "YES!!!" Excellent work, Kevin!

Daytime testing of the Slider e100 and Crate Loop
satya@...
Hi all:
I had a chance to try out the Slider e100 with and without the Crate Loop this morning to see what kind of improvement in sensitivity and selectivity could be had with the hottest receiver around. For stations that were already doing well on the barefoot Slider, improvements with the Crate Loop were often quite modest. However, with targets that were weak and/or suffering interference from strong locals, the results were often dramatic. Some examples were: 530 the Slider had the airport TIS station with fairly reasonable audio, but nothing else, since it was not that far above the noise floor. With the Crate Loop, the airport TIS came in clear, and the more distant TIS station for the mountain pass on I-90 was also intelligible above a much quieter noise floor. 560 in the shadow of a very strong local on 570 (KVI, 5kw about 14 miles away) nulled to the extent possible, the Slider had a semi-local (KPQ) fairly good with mostly-intelligible audio under moderate interference. With the Crate Loop in adjacent orientation, the audio was clearly intelligible and the interference much reduced. 670 the Slider had KBOI (420 miles away) with fairly intelligible audio that occasionally dipped below intelligibility and/or disappeared during fades. The Crate Loop had consistent good audio that remained intelligible during most of the the fades. 680 the Slider had a semi-local old-time music station with decent signal but suffering horribly from an image/heterodyne from a strong local on 1590. With the Crate Loop in adjacent orientation to notch out 1590, the image disappeared and the music station was in the clear. 1060 the Slider had nothing but interference from a nulled strong local on 1050 (KBLE, 5kw about 7 miles away). With the Crate Loop in facing orientation, CKMX in Calgary (450 miles away) had reasonable CW music, and the interference was noticeably reduced. 1110 the Slider had a 500 watt semi-local (KDWB, about 50 miles away) with mumbling audio. With the Crate Loop in facing orientation, the audio was clearly intelligible. 1140 the Slider had CHRB (440 miles away) with mumbling audio under heavy interference from a nulled strong local on 1150, while the Crate Loop in adjacent orientation brought it in with intelligible audio and almost no interference. 1530 the Slider had KFBK-Sacramento (600 miles away) with somewhat intelligible audio, while the Crate Loop had clear audio. 1640 the Slider had semi-local KDZR with acceptable audio (if Radio Disney programming can be referred to as such... :-), while the audio with Crate Loop was much better (correction: much clearer... :-). 73 - Kevin S Bainbridge Island, WA |

Daytime testing of the Slider e100 and Crate Loop
Hello Kevin,
Great work on your Crate Loop article posted on
DXer.Ca, and also on the fantastic daytime DX catches with your Slider E100,
assisted by the Crate Loop. Those are really some outstanding catches,
even for the enhanced daytime conditions currently prevailing.
As crammed as my tiny shack is with multiple
loopstick hot-rodding experiments, after reading your Crate Loop article, I
think there might just be space for another project
:>) Congratulations again, and have lots of fun with
your little Slider DX monster this winter.
73, Gary

Re: Slider antenna vs. C. Crane Twin Coil
Hello Paul,
The stock E100 has a poorly shaped, flat loopstick
which makes inductive coupling with external passive loop systems marginal at
best. To my knowledge, every user of a Slider E100 has found it superior
in DX performance to a stock E100 with either a Terk, SAT, Twin Coil, Q-stick,
Quantum Loop or other accessory. This is based on observations by Kirk
Allen, Kevin Schanilec, myself and others.
These passive and active loop systems usually
provide a greater boost with other Ultralight radio designs, because
of better-designed stock loopsticks in these other models.

The Crate is great. I've seen a couple of others made this way... they typically have good gain but kinda weird nulls... and if strong enough you can sit on it!!!
Put it on a coaster and you can swivel DX.
Nice Kevin... keep that brain cooking!!

The Crate Loop - now available at DXer.ca
satya@...
Hi all:
Just published on the DXer.ca web site are the detailed plans for The Crate Loop, a quick, cheap and easy way to make a very capable passive loop antenna which far exceeds the capabilities of the Terk, Select-A-Tenna and other similar loops. I created it to make a loop that would be effective with the Eton e100 Slider, but it is a killer loop for any portable radio or desktop ferrite loop like the Quantum Loop.

I'm sure you will have lots of fun starting from Scratch with the ULR's...and watching your totals grow on a daily basis. Along the way you will log some amazing DX ...especially for a Hand Held Radio...... I'm sure you will receive lots of encouragement and help from the ULR DX Community along the way, and I take this moment to say that I hope you have a Great Time on your ULR Journey!! The bottom line is ...Having FUN...so when the going gets a little rough...hang in there and you should be rewarded with a healthy ULR Logbook at the end of 2009. I for one am looking forward to see what you can do Bert....and I think this would be a great challenge to other ULR DX'ers who may wish to attempt the ONE YEAR ULR Challenge!! Since this is the First Day of the New Year...why not start a ONE YEAR ULR Challenge...and compare notes at the end of the year. What a great way to stimulate AM BCB DXing....and add a Pile of DX to your logbook at the same time!! Hey...Maybe the ULR Awards Committee can come up with some kind of award for those participating and logging all the stations they hear in a ONE YEAR CHALLENGE!! Maybe we`ll talk about this and see how it can be structured....I`ll see what John Bryant and Gary Debock think about this.... Go get 'em Bert....and hopefully a few others will pick up the challenge...and join you in your quest!! One Caveat Bert........ This form of entertainment can become VERY ADDICTIVE...and may seriously interfere with Sleep Patterns as you know them!! HAHA Have Fun and Happy ULR YEAR!! 73...ROB. Robert S.

(IEN-GA) *****I realize this may seem an odd station to report, but in a shameless attempt to perhaps duplicate the amazing feat of fellow DX'er Robert Ross, I am going to report everything I hear in 2009 on one of the four Ultralights I own. There will be a lot of relogs in there, I hope, but I want to see what can be heard here on an Ultralight regardless of what it might be. Will I top 600 like he did? Only time will tell. Wish me luck in my endeavor.

Happy Ultralight New Year (read at own risk)
Hello Guys,
One of the primary culprits for the Ultralight
radio craze would like to wish every one of you an exciting, DX-filled 2009,
with thrilling pocket radio DX to fill your new year! May you all have the
productivity of Rob Ross, the luck of Allen Willie, the DXing knowledge of John
Bryant, and the technical wizardry of Steve Ratzlaff!
Back from New Year's Day in 2008 (and
completely without any popular demand), for those of you with strong stomachs, I
offer this awful selection of poetry from the very early days of Ultralight
Radio. Feel free to read it at your own risk, and have a wonderful New
Year!
HAPPY ULTRALIGHT NEW YEAR (1-1-2008)
The weather is icy, the snow is quite deep... The TA's and TP's have fallen asleep. The bands they are dreary, the Asians are gone... The current conditions provoke a big yawn. But deep in our hearts, we know there is hope.. A new day is dawning, no reason to mope. We hold in our hands the key to success.. A tiny receiver that banishes stress. It warms the winter like cookies from Mom, And zaps IBOC gloom like a nuclear bomb. It nulls all your pests, eats locals for lunch... And of all of your toys is the best of the bunch! When winter is over, and spring shall appear.. We all know DXers will jump with great cheer. For tiny receivers will lead us to joy... And make us all feel like we did as a boy. We may not be young now, and over the hill.. But these tiny toys still provoke a great thrill. The Club, it has hope now, the future is bright.. Happy New Year to All... with a new Ultralight! 73 and Apologies to All, Gary DeBock |
