Good Morning or whatever it is at your QTH,

After listening to 1540 quite a bit during the last few weeks, I finally was able to dig out an ID on a previously UNID SS station. Hrd on both the T-615 and Eton E-100 Slider w/ SAT.

1540, XERTP, San Martin Texmelucan, Puebla, 0948 UTC, 7/30/11, playing a variety of SS vcl mx. Clear "La Poderosa Puebla" ID copied finally. Sig was good enough this morning that I actually recognized the canned announcer's voice after hearing the sta quite a few times while in the Houston area. Mixing w/ a UNID SS sta who was airing a pgm called "La Voz Christiana." Sta #776, LAm #153-

That's all for now from northern Oklahoma. Take care and good DX to you all.

Re: How To Calculate Ferrite Loopstick Inductance Values for Ultralites? Part 2

jerry_popiel
 

Great informative comments Paul. I am wondering if replacing my Single Gang Variable Capacitor for my longwave Antenna Trap shown in photos section (designed by Michael in UK) with a 3 Gang Capacitor might add some Capacitance and provide more Selectivity to this project?

Also if I understand what you wrote, then the measured value of 670 uh for my Inductively Coupled 5.5 inch 80 turn Litz Wire Ferrite Rod Loop is within Broadcast Band Specs, but I'm not sure how I am receiving Beacons so well if 1800-2500 uh is the required inductance value?

Thanks
Jerry

The other part of your question is quite difficult. One inductor generally does not do both AM-Band and the Beacon-Band *well*. There are compromises. This is due to the frequency range of both bands. AM is 520-1710kHz and Beacons are 200-500kHz. Even lower in frequency is the International Long-wave band at 150-270kHz.

Because these other frequencies are lower, a larger-valued inductor is needed. As noted Gary's Long-Wave inductor is 1700uH, about 5 times the value of an AM-band inductor. This requires great skill in producing one. Many turns are needed using generally thin wire. Thus the ferrite length is also large. About the only compromise is to use a stronger ferrite with a larger diameter. The problem is that these stronger ferrites are also conductive, and one must insulate the coil from the ferrite "just in case", and as a matter of good practice.

These qualities have led to the use of "ferrite sleeves" or tubes with a large diameter, but rather thin ferrite thickness. Again, the sleeve *must* be insulated from the wire.

What is good? Well, for Beacons, 1800-2500 uH is ok. For International Long-wave 3000-4000 uH. As a compromise involving physical size and usually $100 or so, a multi-ganged variable capacitor (four sections of 360-400pF) and be wired up. Now the tuning range is extended by capacitance: not by inductance. Doing this also involves using a *reducer* so that the 1/2 rotation of the variable is increased to 3 turns. I would recomment 2 of these for 18 turns: the slightest movement will pass a station (or beacon) or two!

--- In ultralightdx@..., "ferrite61" <dxrx@> wrote:

Since you already have a reasonable estimate of the inductance, the tuning capacitance is based upon that. For about 680 uH (0.681 mH) tuning to the bottom of the AM-band is 138 pF, with the top end having a lower capacitance of about 12.5 pF. That range is too low (meaning the inductance is too high). Reducing the inductance is accomplished by removing turns of wire from the ferrite bar/rod. Without a general formula, its a trial-and-error process. But a general rule of thumb can be used.

Since you have 80 turns and the measured inductance is 680uH, we can scale-down the inductance by ratio of the square of the turns. For example a new inductance can be estimated by 60x60 / 80x80. Thats 3600 / 6400 times the 680uH giving an estimate of 382.5uH. This example is quite suitable in UL-Radios, especially the new DSP sets.

On the other hand if you need more inductance adding turns is needed and an example of 40 turns with 150 uH would solve as 60x60 / 40x40 times the 150uH. 3600 / 1600 x 150 is 337.5uH. Again this answer is suitable.

In general, most newer sets use "the reverse of the original specification" being 250uH and 360pF. Today, for purposes of better low-end reception, most manufacturers like 360uH with 250pF. Some are even 470uH and 200pF.

So now that's done, the quality of the inductor becomes important. Centering the turns on the bar/rod is important, and also spacing the turns of litz a little will help. Try to keep the length of all turns less than 2/3 of the ferrite length... optimal is 2/5 of the length. Fine-points include insulating the wire from the ferrite by using a layer or two of heat-shrink tubing. The object is to get the sharp tuning in the tuner, because the filtering (IF) stages will reduce the sharpness... you may hear an adjacent strong station on most UL-Radios.

This question is likely for the Experts. How do you know what Inductance values are acceptable for MW and LW Listening? That is, I have an older 5.5 inch Ferrite Bar Antenna with approx 80 turns of Litz wire on it, that I am using to couple to a PL 380. It measures 0.671 mH on my DM 4070 LCR Meter. Is that Inductance Value acceptable, or what is / or how do I know what is the required value?

Or does this depend on the length and diameter of the Ferrite Bar - such as the 122 turns and 1700 uH of 100/44 Litz wire that Gary DeBock has said is required for his 7.5 Ferrite Rod Antenna for the Pl 380? Any replies would be very much appreciated

Farmerik, just click on the Links, and paste them in Google, then hit search. Or you can go to YouTube and Punch in Tecsun PL 380 Antennas and Search. Had a look at both of the Videos, its a bit difficult to tell what is happening, but I think an 18 inch or 30 cm 10 Turn Cardboard Loop is replacing a Ferrite Bar Loop with the same performance results. There is also a Terk type Loop in the mix as well.

Re: Speaking of ULR's - FARMERIK

Rik
 

Thanks Keith. Nice to 'speak' again. I think this one sells for roughly 2X as much, so I was hoping it had better electronics as well as fancier styling. Mine should be shipped soon from UK, so I will mention how it seems after I get it. It sounds like the one you have is fine for the glove box sort of use I have in mind for it.

I decided to also order the ICF-304 which will ship from Asia. From the specs, it may be about the size of my PL-310, so it might be a ULR too. I'll see when it gets here.

I do have a couple SONY Walkman's for a quick comparison, in a few weeks.

Hideeho,

At the beginning of my weekend, I almost felt human (after working in the heat all week) and decided I'd betta get the headphones donned. I immediately noticed that Mexican stations were boom-booming in, so I started checking my XE hit-list for a new sta. It did pay off. Logged this newbie on the T-615 w/ SAT. Slightly worse reception on the E-100.

XEDN, Torreon, CO, 1105, 7/29/11, TWO SS stations on this freq! Previously 0% LAm stations have been noted here since I started gettin' serious w/ the ultralights. Pleasantly surprised to hear the XE NA playing upon 1105 arrival on the freq. Caught a call letter ID following some brief chatter (not copiable) @ 1110 UTC. In Houston, this one was fairly EZ to hear. ULR Sta #775, LAm #152-


Also worth noting:

1030, UNID SS Stations, 1125 utc, 7/29/11, maybe relogs here, but I'm uncertain. One of the stations was airing pop styled SS vcl mx while the other one was all talk from what I hrd.

1160, 1144 utc, 7/29/11, never hrd a SS sta here in Okieland before now. This AM there were TWO stations airing SS pgms. Both of them reamin UNID'd for now, but this is certainly a channel to check back in on before conditions change and render it fatally anemic.

Thanks, Farmerik, and all who are joining this conversation. As Paul mentioned, the question of "What Is An Ultralight, And Why?" does come up from time to time here on the Group, including the status of SSB capability, DSP filtering, etc. The criteria were developed a few years ago, and in some ways are in fact somewhat arbitrary, but were developed with a lot of care and attention, and are what they are. They are in PDF from in "Folder 1 - Start Here" in the Files section here if anyone wouild like to take a peek.



Posts regarding why something should or should not be a defining criterion is fine. I/we only ask that folks respect that those are in fact the criteria that from the basis of the Group, and not belabor the point or insist that the Definitions be changed to their individual way of seeing things.



We welcome all into our discussions here (other than those pesky spammers!), whether or not they actually use an ULR, and hope that the topics discussed here can benefit all radio enthusiasts.

Yes, I'm sure that John would have had something interesting to say
about me logging the new Ultralight country of 666-New Caledonia if he
was still with us. I remember sneaking a new Asian country by him in
October of 2008 (675-VOV in Vietnam) with an E100 Slider model here in

of course :-)

It's explained very clearly on the web site.

specifically:

"iSDR does not require Internet connectivity, a cellular network,

signals into audio signals that can be fed into the iPhone's microphone
input"
