Hi all,

I know this is off topic but was wondering can anyone suggest a suitable
ferrite core for general listening from long wave up to 30 mhz - does such
a core exist?.

I found a T 200 - 2 in my junk box but when I worked out the turns needed
to cover 1 - 30 mhz it was something crazy. Any suggestions for something
useful for this one?.

Gary's SRF-39 with the big loopstick

sloshatron <wa1gwh@...>
 

Hi Folks;

Very interesting antenna transplant that Gary performed on the SRF-
39. Any special reason that the coils are way out on the ends of the
ferrite bar? I presume the original antenna and the big transplant
needed the coils separated to allow movement for alignment.

The reason I ask is that on the crystal set discussion group that I
participate in, Ben Tongue (of Blonder-Tongue fame) has pointed us to
an article of his where he examines the efficient construction of
ferrite bar inductors. He has concluded that best performance occurs
with the coil centered and occupying no more than about 1/3 of the
bar's length.

I wonder if the total inductance required for an SRF radio could be
brought about with the two coils closer together and more or less
centered? Perhaps a few turns would have to be removed from one or
the other coil in order to counter any possible increase in total
inductance by having them closer together.

I can't see why an air core loop could not be used as a transplant
antenna. Except for the distributed capacity differences (and I'm
not sure how a ferrite inductor vs an air core one varies) I think
that an inductor is an inductor. The one difficulty I can think of
is how to tune the darn thing for alignment purposes. I guess you
could measure signal strength with a meter at the audio output, and
then remove turns as you go through the same alignment procedure as
with a ferrite bar. It would be a slower process and might involve
adding back fractional turns. The meter would enable the alignment
scheme to work in though you have to turn off the radio and remove
turns.

The reason I bring up air core loops is that crystal set
experimenter's have pointed out quite a bit of variability of
performance in ferrite bars. An air core loop would eliminate this
problem as well as finding a suitable bar.

I have copied Gil Stacy's idea of a variable capacitor and an
inductor as a booster antenna on my SRF-49. Except that I used a 4
1/2 inch air core coil of #21 wire basket wound (left over from a
crystal set project!). I gives a very prominent boost in
performance, so I presume one like it or bigger, of suitable
inductance, might work very well.

Comments?

Thank you,

Garry Nichols

Hello Garry,
 
     Thanks for your comments on the SRF-39FP mega-antenna transplant, and welcome to the discussion.  The crystal set group and the ultralight radio group seem to have a lot in common (interest in maximum performance from minimal equipment), so we are especially happy to welcome enthusiasts from your side of the AM-DX hobby.
 
     My interest in huge transplanted loopsticks grew out of a fascination with the SRF-59's stock DX performance, with only the tiny 1.75" ferrite bar.  After receiving three TP's with this miniscule antenna, I began to seriously wonder what the amazing CXA1129 chip could do with a generous DX antenna, and whether such a combination would outperform the classic DX portables (ICF-2010, E1, ICF-S5W) in sensitivity.
 
     Alignment of about 25 SRF-59's (for myself and others) gave me a good idea of how the stock loopstick works, i.e. a fixed longer coil with a tap point, and a smaller, movable coil used for alignment.  Around February, in an experiment documented on dxer.ca., I transplanted my first 6.25" ferrite bar into an SRF-39FP "prison radio," which is basically an SRF-59 with a bigger tuning dial, and better components.  The first "Super Prison Radio" was constructed without an LCR meter, and essentially was an exact copy of the stock loopstick, although on a larger scale.  It had definite alignment peaks at 600 kHz and 1400 kHz, and had sensitivity roughly equal to the ICF-2010 (better on some frequencies, slightly worse on others).
 
     Using an accurate LCR meter, further experiments were conducted on three other (6.25" and 7") loopsticks,  using recycled coils with inductances carefully matched to the stock coils.  After careful alignment, these units had sensitivity generally superior to the ICF-2010 on all frequencies.  They deadlocked with the ICF-S5W on the lower and middle frequencies, but these "SPR2" units were more sensitive on the high end than the S5W.
 
     The recent experiment, using two 7.25" ferrite bars tightly taped together, resulted in an "SPR3" unit with a total antenna length of 14.5", and sensitivity clearly superior to any stock portable on every frequency.  Concerning the separation of the larger and smaller coils on the loopstick, Garry, this was primarily a convenience for construction, since the loopstick mounting post is attached to the center of the loopstick for secure mounting, and also the smaller coil needs about 2" of space to find the 600 KHz alignment peak, even after the optimum inductance of .598 mh is obtained across both coils. 
 
     Concerning  Ben Tongue's impression that ferrite bar loopsticks have the best performance when the coils are centered (and occupying no more than 30% of the bar's length),  I have constructed SRF-39FP loopstick transplants where the both coils were near the center, and found performance identical to the "separated" orientation.  We must remember that Sony engineered the SRF-59/39 loopstick with separated coils (presumably for alignment), and that the stock loopstick has fantastic DX performance for its size, in the "separated" orientation.  If a hobbyist wished to have both coils near the center of the bar, he would have a tricky alignment process, and would also need to construct a support framework that avoided the coils (making the support look something like a slingshot).  IMHO, such additional hassle wouldn't give any real DX improvement, Garry.  Thanks again for your interest in the mega-transplant!

Hello everyone,

Today is the second anniversary of passing my first amateur radio exam
so I thought it would be a great day to joing this list as well. Not
too much planned for this weekend, but am going to try for the CBA
Moncton DX Test using both Sonys, the SRF-59 and the ICF-2010. Maybe
they will send 2 QSLs, hi hi hi.

Congrats on #450 Rob, that's more than what I've ever done in my noise
infected QTH with my 2010.

See you all later...

Joe

Hi Guys:

Well.......I'm off to the Semi-Annual ODXA DX Camp in the
morning.........will be there til Sunday afternoon. It is held North of
Toronto....so we're a Long Way from any Ocean ....but there is a Tiny
Little Lake located at the camp.......Musselman Lake...I think it's named
after all the He-Men that go to the DX Camp!! HAHAHHAHA.......

Saul Chernos and Niel Wolfish from Toronto are also going to be in
attendance.....so we'll have good ULR DX'er Presence there.

I have a Bag of ULR's all packed and ready to go.........2 Sony SRF-39's, 2
SRF-59's, a Sony SRF-T615, and an ETON E-100........all aligned by Gary
Debock to assure Maximum DX Potential!!!

Now we just have to pray to the DX Gods for good conditions....and LOW
Noise Levels!!

I'm also taking a DRAKE R8B along......just in case .......or I decide to
do some Short Wave DX'ing.

Anyways.....I have enough ULR's to give everyone in attendance a chance to
try them out.......so we may be able to get a few more ULR ADDICTS signed
up for the 12 Step program!! HAHHAHA.....

We'll let everyone know how we do when we get back. This is always a lot of
fun....10 or 12 Crazy Buggers all squashed into a single room with a
Million Radios.........and a few Cases of Beer!!! With those
armaments.......anything should be possible....

Wish us luck!!

SRF-59 coupled to ferrite bars

lrdheat
 

Dear folks,

Gary's mating of a large ferrite bar to the SRF-59 would be highly
desirable. Like another earlier post, I shy away from opening radios
as "disaster would be sure to follw". I am including a part of a note
that I sent to Gary describing my experience today with inductively
coupling the SRF-59 to a couple of radios with large ferrite bars.
There are some nice pluses to using a radio as opposed to tunable
ferrite bars or selectattena types(sp?)in that the tuning display of
the radio will provide an excellent indication as to what frequency
the ferrite bar is tuned to!

I found today that the coupling my SRF-59 with the antenna in either a
SANGEAN PR-D5, or with a SONY ICF-EX5 makes the SRF-59 slightly more
sensitive than either set. The PR-D5 has to be on for this coupling to
work. That is good and bad...it means that I am using the PR-D5's
batteries during a dxing session, but it also means that it is easy to
properly tune the PR-D5's antenna to the frequency that I hope to peak
on the SRF-59!. The coupling has a very sharp null, and a fairly
narrow peaking window...just offtuning 10 KHz is noticable, and an
offset of 20 KHz is quite noticable. In the case of the analog SONY
ICF-EX5, the EX-5 need not be on...tuning the sliderule indicator to
the frequency of interest results in a pronounced peaking of the
signal on the SRF-59 with about as much of a boost as produced with
the PR-D5.

The attraction of your experimental homebrews is that it does not
employ two items that need to be tuned for each frequency of interest,
and that it is much more portable, has a much smaller footprint.

I'm back...this is a neat refreshing change from the swl'ing that I
had been doing, and harkens back to my days as a youngster staying up
to all hours of the night listening to dx on a 6 transistor set using
the radiator in my room as an antenna.

What type of tips might you have for trying to catch trans Atlantic dx
from Laredo, TX?

Re: SRF-59 coupled to ferrite bars

Gary DeBock
 

Hello Richard,
 
     Thanks for your comments, and the information on your SRF-59 inductive coupling with the PR-D5 and ICF-EX5.  Your approach is one that's new to me, although booster bars (such as the excellent units kindly made and given by Gil Stacy and Kevin Schanilec) are heavily used here, and most of the TP's I logged on the ICF-2010 last fall were inductively coupled from the Quantum Loop 2.0+, which of course required tuning twice.
 
     The loopstick transplants, especially the latest (SPR2 7.25" and SPR3 14.5") experiments, generally boost the SRF-39FP sensitivity past the ICF-2010 stock level, but not past the 2010 + Quantum Loop level. The 2010 + Quantum Loop is a very effective combination, although it does require tuning twice. It would be like a dream to construct a stand-alone modified Ultralight, with the same sensitivity as the 2010 + QL combination.  I think it's possible, but the loopstick may not fit through a standard doorway  :>)
 
     Loopstick transplant science has had a tremendous boost because of the Ultralight phenomena, but these improvements are not limited to Ultralights.  It would now be routine to give radios like the ICF-2010 and ICF-SW7600GR larger, more effective antennas, assuming the owner could live with an external mounting system.  My own impression is that an ICF-2010 with a 14" loopstick could outperform a 2010 + QL combination, but we will never know for sure until somebody actually tries it. 
 
     Thanks again for your comments, Heatwave, and the "Super Prison Radio 2" article should be finished soon, giving everyone detailed instructions on making this DX dynamo from a commonly-available 7.25" loopstick.

Kirk,

Welcome to ultralightdx!  You mentioned needing a comprehensive list of broadcast band stations.... I'd been meaning to write to you about that.  My favorite web site is http://topazdesigns.com/ambc/  THat is a two part site.... on the right-hand side, you can search a particular frequency for call letters (including a nice "fuzzy search" feature) or you can search a particular frequency by format of the broadcast.  On the left-hand side, you can put your home geo coordinates into the blanks (just have to enter once) and then type in the call letters.... searches every frequency for the station, gives you all sorts of info on the station and the distance from you to them, etc.

Another good one is http://www.radio-locator.com/

A third one that is a more conventional listing, and very good, is http://www.amlogbook.com/

Then you have to start looking for individual countries.  You can google Fred Cantu's site for Mexicans and Bruce Conti has an EXCELLENT Cuban list.

There may be other resources out there that other members could suggest. Perhaps we should put these things in the Links section of our website.  I know that there are some amateur radio operators interested in ultralighting and they are probably like Kirk.... relying on memories that are 20 or 30 years old, as far as BCB DXing is concerned.

Anyone else out there with suggestions?

Hi Everyone,

I just joined this group thanks to info from my old friend, John Bryant. I'm very new to this aspect of MW DX'ing. Also tnx to John, I'm using an SRF-59. Due to time constraints during the night and early mornings, I've only just begun, but looking forward to many more hours of fun with this. I'm an old (literally)  DX'er starting in the early 1980's but mainly on the HF bands. I've not heard any station that's considered outstanding yet. Have only hrd one XE that I could ID on 850 kHz-XEM, R. Exitos, but have heard a few domestic stations that I  don't believe I've ever logged before (but my memory for MW is rather faint.) I intend on finding a comprehensive listing of MW stations asap. Any suggestions? Greeting to all and 73!

Re: "March Madness" Project-- A 14.5 inch Loopstick Transplant for the SRF-39FP

John H. Bryant <bjohnorcas@...>
 

Gary!

Great transplant operation!!!  Several questions:

1. Where did you get the Litz wire that you are using to wind the coils?  What size is it?

2. Are you following the L values from that one-page paper of the Bryant/Hall-Patch tests of the SRF-39FP ferrite antenna (in our Files section)?? If you are, are you still getting great results "right out of the box" using those "L" values to wind the coils???

3. What determines the distance between the ferrite new bar and the top of the SRF-39??

4. Have you tried running the connecting wires parallel to the bar (as they run in the stock unit) and then vertically down the ruler, rather than diagonally?  Is their a measurable loss?

A couple of suggestions for further experimentation: When Bill Bowers and I were building the 8'-0" Monster Ferrite bar antenna, Bill did a good bit of careful experimentation with the 3/4" x 12" bars from which the Monster was constructed. He found that there was a significant reduction in gain if the butt ends of the bars were not PERFECTLY flat together.  He proved that finding in the field when our 4"x 4" redwood support beam under the bundle of ferrite bars started sagging (yes!) That slight sag plus changes in temperature (the Monster was mounted outside) opened up tiny wedge-shaped spaces between the flat bar ends and there was quite a loss of gain. Bill ended up putting a cap over each end of the monster and then putting bolts in threaded holes in the caps to put each line of ferrite bars in serious compression. In your photos, it appears that the two bars are sagging a bit.  Maybe the ends that you are working with are not perfectly square and you are getting good contact, despite the apparent sag.

Another thing that Bill learned is that even with perfect contact between the ends of two bars, laying in a third bar that overlaps the joint of the first two by at least 1/3 of its length made a very measurable increase in gain.... more than could be accounted for just by the additional mass of ferrite.  So, you might want to try adding a third bar in close contact with and overlapping the first two..... sort of magnetically reinforcing that center joint.... I wonder if you would increase gain even further???

In the third bar approach, Bill said that it was as if the magnetic lines of force flowed through that third bar, bypassing the joint between the first two.... might be worth a try?

Anyway, Gary, great transplant operation.... let us know how it goes at Grayland!

Hello Guys,
 
     Welcome to all ultralight DX enthusiasts!  We are all especially happy to have a growing ULR fan base in Europe and South America, and feel honored to have you as part of our enthusiastic team.
 
     In search of the ultimate DX portable, a 14.5" loopstick was successfully transplanted into an SRF-39FP "Prison Radio," by use of an LCR meter, and two 7.25" ferrite bars tightly wound with heavy-duty tape.  After full alignment, the sensitivity apparently exceeds any stock portable in sight (ICF-2010, E1, ICF-S5W, etc.).
The most exciting point is that the loopstick was constructed of readily available parts, and the entire experiment cost less than $60 US.  A full article on this "Super Prison Radio 3" will be available shortly, documenting all the steps and part sources.
 
     Three photos of this DX Monster have been uploaded to the Ultralightdx Yahoo Group site, and it is rumored that this ultimate Ultralight may soon haunt the shores of Grayland, Washington.  This radio is so much DX fun, it should be illegal!

The Ultralightdx Web Site: Content, Uploading, etc.

John H. Bryant <bjohnorcas@...>
 



I am certain that most people on here are already familiar with the details/services available to members of a yahoo group.  In case that you are not, here are some comments that you might find helpful:

1. Our ultralight group has its own website. The URL is http://groups.yahoo.com/group/ultralightdx/ You might want to make a shortcut to that website on your desk top or put it in your favorites, because much of the advantage of belonging to this group is only accessible on the website itself.

2. You can access all past messages to ultralightdx on the site. Further (and this is key) you can search the message archive for a particular word or phrase, or station or frequency, etc.  Very handy as our archive of old messages builds up.

3. There is a "Files" area on the website that, right now, just contains one paper: the results of testing of the ferrite rod antenna (its coils, actually) of the SRF-39/59 family by Nick Hall-Patch and me.... there are results from three antennas.  So, if you are transplanting a larger ferrite bar into one of this family of receivers, this information and an LCR meter is very useful.  Over time, I hope that we will build up other "in progress" and technical references in our files area.  This is also the place for anyone who wishes to upload audio clips of Ultralight catches that the might wish to share. There is 100 MB of free storage available for our Files, so we should have plenty of room, for a while. As we build up files, I'll likely apply some sort of organization into folders to aid navigation, but for now, please just upload all files and clips into the main Files area.

A word of caution, though, this Files area should not be viewed as the primary repository for Articles, etc. on Ultralighting. The DXer.ca website has served us very well as a central library of articles on all aspects of Ultralighting.  More importantly, it is seen by the broader MW and Crystal DX hobbies as The Place for information and files regarding Ultralighting.  The most downloaded file in our area there has been downloaded over 500 times (!!!) If you have any finished Ultralight articles or references, lets make certain that a copy goes to DXer.ca. If you can't upload to that site (its somewhat restricted in upload privileges) please send it to me and I'll be happy to upload it for us all to see.  Most of these same comments apply also to the club bulletins of IRCA, NRC, ODXA and MWC. Each of these publications has been very supportive of the Ultralighting niche and would welcome more articles from members of this group.

4. I did not realize it until recently, but Yahoo also supplies its groups with an additional 100 MB of storage in the "Photos" section of the website. Right now, there are several interesting photo albums already there.  Gary DeBock has uploaded photos of his latest transplant of (now) an almost 15" long ferrite bar antenna onto an SRF-39FP.... a pretty incredible feat.  I've also put up two albums of photos of my "National" SRF-39 Table model receiver.  If you saw these photos on the old hotrodding website, the only thing new is one page of my preliminary design sketches... you might like to compare the initial design to the final product. Articles about both of these projects will be forthcoming in the next month or so, I'm sure.

Several practical things about the Photos section of our website. First, its super for people who are not really used to manipulating their digital images as to size, resolution, etc or optimizing them for the web.  The Yahoo Photo section does that work for you, automatically!  You can upload almost any size Photo file to an album very easily and the Yahoo software optimizes it for the web and creates THREE images of differing sizes: A Thumbnail sketch, a Medium Size Image and a Large Image. When you go to an album, you see the humbnails. If you click on one, it brings up the medium image AND THE CAPTION. To the lower left of the photo is also a link to click to get the really large detailed image. I really like the automatic nature of this... and he fact that one can select the size image to view.

Apparently each "album" is limited to five photos and it is not possible to establish sub-Albums within an overall album. Still, it is a wonderful resource for us all and I hope that you use it.

Any ultralight member can upload to either the Files or the Photo section.  If you have not done it before, its quite easy.

Lastly, I see that Allen Willie has uploaded a photo of he and fellow St. Johns DXer Lorne Harnum to the Photos section. THANKS, ALLEN!  Two very handsome gentleman.  I hope that we can create a Ultralight rogues gallery...

Well, that is all of the mechanics that I know about for our group.... The next step for me is that custom dial face for the National SRF-39.

Hi Guys:

Well.....exactly 3 months to the day after starting ULR DX'ing....I
have logged station # 450......That being 1310 WNAE Warren, PA.

Below are my 3 Logs leading up to # 450 this past weekend.

All 3 of these loggings are on the ETON E-100 ULR. 2 of the 3 loggings are
NEW to the OVERALL LOG.

The first month I logged 300 stations....the second month I logged 100
Stations, and the third month I logged 50 Stations.....so as you
see....things are getting a little tougher as I progress. Wonder how long
the next 50 and # 500 will take????

73..........ROB.

"March Madness" Project-- A 14.5 inch Loopstick Transplant for the SRF-39FP

Gary DeBock
 

Hello Guys,
 
     Welcome to all ultralight DX enthusiasts!  We are all especially happy to have a growing ULR fan base in Europe and South America, and feel honored to have you as part of our enthusiastic team.
 
     In search of the ultimate DX portable, a 14.5" loopstick was successfully transplanted into an SRF-39FP "Prison Radio," by use of an LCR meter, and two 7.25" ferrite bars tightly wound with heavy-duty tape.  After full alignment, the sensitivity apparently exceeds any stock portable in sight (ICF-2010, E1, ICF-S5W, etc.).
The most exciting point is that the loopstick was constructed of readily available parts, and the entire experiment cost less than $60 US.  A full article on this "Super Prison Radio 3" will be available shortly, documenting all the steps and part sources.
 
     Three photos of this DX Monster have been uploaded to the Ultralightdx Yahoo Group site, and it is rumored that this ultimate Ultralight may soon haunt the shores of Grayland, Washington.  This radio is so much DX fun, it should be illegal!
 
                                                                                        73,  Gary DeBock

Hi Everyone,

I just joined this group thanks to info from my old friend, John Bryant. I'm very new to this aspect of MW DX'ing. Also tnx to John, I'm using an SRF-59. Due to time constraints during the night and early mornings, I've only just begun, but looking forward to many more hours of fun with this. I'm an old (literally)  DX'er starting in the early 1980's but mainly on the HF bands. I've not heard any station that's considered outstanding yet. Have only hrd one XE that I could ID on 850 kHz-XEM, R. Exitos, but have heard a few domestic stations that I  don't believe I've ever logged before (but my memory for MW is rather faint.) I intend on finding a comprehensive listing of MW stations asap. Any suggestions? Greeting to all and 73!

Thanks for the invitation

Thanks to whoever invited me to join this group.

I probably haven't used either my SRF-59 or SRF-39FP nearly as much as
most of you. Everyone I've shown the FP to thinks it's very cool
looking especially after I tell them why it's transparent and show
them that the ear buds, cord and plug are also transparent. I'm not
sure what you could hide in there that could be considered dangerous.
I really dislike ear buds and use my very best Sennheiser headphones.
Well engineered stations sound awesome.

I haven't done a daytime bandscan with either one. I haven't tried
using the Select-a-Tenna with them although I'm sure it will help.

I don't open up radios because disaster is certain to follow. When my
life gets a little less complicated I'll have Gary work his magic on both.
