Date   

Three new DX's heard this early morning

ferrite61 <dxrx@...>
 

I was up early at 0230EDT to catch R Australia, but instead got distracted a bit by the upper AM-BCB.

1510 WLAC Nashville, TN was strong enough to get a ToH ID at 0300 EDT. WWZN is usually allover this preventing ID, along with substantial QRM/N. This morning, was that rather rare case of bad local propagation and low noise. After 5 years its about time ! This got me interested in other stations in this band segment.

1510 WLAC Nashville, TN 50000W at 1376 km.

Next up was 1520, for an attempt at getting an ID of the C&W station located with WWKB during bad PGX. Finally got this one after 3+ years as WMLM mention during a station break at 0320 EDT.

Upon lookup: 1520 WMLM St. Louis, MI 1000W at 981km

1530 nothing new, but 1540 got me another long-sought prize Zed-NS1 Bahamas. This has always been difficult with CHIN, WDCD, KXEL. I could hear the distinctive Carribbean rhythms, but never an ID to prove it. This morning at 0400 finally caught "...National Service, serving the Carribbean." Best ID I ever got in 5 years of listening, and good enough. This was with radio facing SSW to reduce CHIN that was doing some radio service relay this auto-programming. Might be CRI, or CNR system by the sounds.Other talk radio/news was WDCD due to non-branded newscast.

1540 ZNS1 Nassau, BH 50000W 1876km.

YVXO again heard on 1550 while WDSK (ex-WDZK) Bloomfield, CT remains silent. CBE still strong, but can be nulled enough.

The radio used is the venerable Tecsun PL-200. Now onto R. OZ.

RWW ultralight: one hunder NDBs

VK2DX <nick@...>
 

Hi all,
 
after exactly 15 days I have completed my quest to log 100 NDBs using
little portable ultralight AM receiver TECSUN PL-380 with a single 20cm ferrite rod antenna.
 
Yes, it was fun - and the entire log was completed on single charge
of 3 x 1.5 V batteries! Spent around 20 hours listening in my back yard, walking around the house,
in the park, hilltop overlooking ocean  - and few were even logged form my bedroom!
 
To put things in perspective, this is 1/3 of all beacons logged form Sydney.
 
No, it ain't Perseus, but some beacons were amazingly good copy.
As you know, the timing is everything and being at the right frequency at the right time
was half of the job.
 
Give it a go- you'll LOVE it!
 
Once again thanks to Gary DeBock for inspiration.

Nick....Good show on the 8 new Ones on the NDB Band!!!! You'll be at 100 very soon!!!

That is bizarre that you were on your way to Tokyo when I posted the news of the Japanese Earthquake!!! I guess it's a good thing that your flight was canceled.........Japan is not the place to be right at the moment with all the turmoil and destruction.......

It makes you realize how lucky you are sometimes when you see stuff like this happening in Real Time!!

Keep plugging away and the other beacons will be in the log before long!!

UltralightDX Yahoo Group Moderator note - please watch your inboxes

Hi all:

There is apparently a somewhat heated email exchange going on, off-Group, between two individuals regarding FSL theory. One of the participants is apparently either copying his messages to various members of the Group, or is using the Group email architecture to respond and the messages are being received by various Group members.

Either way, the messages may appear to be from the Group, but that individual is no longer able to post to the Group, and the messages are not reaching the main Yahoo Group message board. They are being sent directly to various members' email accounts. A couple members have responded to the Group board, perhaps not knowing that the main message thread itself is not showing up on the board.

If you choose to respond to this individual, please ensure that the email is being sent directly back to the individual, NOT via the Yahoo Group. Switching your email preference to Daily Digest rather than Individual Email may preclude you from getting these emails from him altogether.

We wish all of our Japanese friends all the best - safety and quick recovery

VK2DX <nick@...>
 

On Friday, I was on bus to airport, heading for Tokyo
when I saw Rob's post on this group about the earthquake. Needless to say, the flight got canceled
Last year I've been through couple of Japanese earthquakes - definitely glad I've missed this one!

This is earthquake is a devastating blow for Japan, but the early signs are that the country is showing resilience in the face of the best nature could throw at it. Japanese are used to quakes and tremors. In circumstances like this, there is no pushing, no yelling, no outward signs of fear even.  The restraint of Japanese people is exemplary.

We wish all of our Japanese friends all the best - safety and quick recovery.

Subject: [ultralightdx] My first shipment of Russian ferrite rods arrived today - WooHoo!


So the mail man brought me a package today. Forty 10x200mm ferrite rods.

First impressions.. Heavy & delicate. I already broke two of the rods.

Anyways.. I decided to use handy at-home items for the core form. Hey what's this? A empty 2 liter soda bottle is just right... 37 rods is a nice tight fit around the bottle. Rods held to the form using double sticky tape and three Rubber bands. Rods then wrapped in two layers of the bubble wrap the orig packaging that the rods came in. Then a few wraps of white paper towels to dress it up. Now to wrap a coil around this thing...

I will update once I have someting working.

Regards,


Re: Ferrite Sleeve Loop (FSL) antenna update

Hi Graham -

I cannot find it in the yahoo messages. What is the message-ID or just post it again.

In your Web-article at http://www.gmweb2.net/The%20FS%20Loop.htm you mentioned 20dB gain. How is this related? To one single-rod? The picture looks like 20+ rods. Is the S/N improved or the signal level only? For what frequency?

Doubling the rod-count will increase signal +3dB [power gain] if the rods behave as not coupled. Nothing new. This will just increase the effective antenna aperture.

Thanks!

- Henry

If you can provide a working example better than what is the common knowledge in practice, than I will just accept this und use it.

I was able to add two new stations to my overall ULR log last night. Times and date are UTC.

3/12/11
0445-0508 171 Radio Mediterranée Internationale, Nador MRC, North African music, singing in Arabic, woman talking in Arabic from 0500. Poor signal strength, barely audible by 0500. PL-360 and 7.5-inch loopstick. (ULR LW #4, country #3, continent #2).


Richard...that's a GOOD ONE!!! I will have to try for them here!!! I have heard RMI on the Big Radios before....so I know it does make appearances here from time to time!!

I had traces of BBC-Radio 4 England on 198 Khz and RTE-1 Ireland on 252 Khz again last night...so there were other LW Signals making it across the Atlantic!


0600-0624 1540 WKVQ, Eatonton GA, DX Test. Poor signal strength with slight KXEL QRM. Also heard at 0700 at fair strength. Sony TRF-T615. (ULR MW #818, barefoot #805, Georgia #6).

I think this is the first time that John, Rob and I have logged the same new station in the same time period. I doubt next week's DX test will be quite as easy.

Best wishes to all for a good DXing weekend.

Richard.

Richard Allen


Yeah..............1540 WKVQ  was getting out pretty far......heard in England and Oregon as well. I'm sure a lot of ULR DX Group Members would have heard WKVQ Last night if they were still up at 0100 EST last night.......

Well......all 3 of us won't be hearing next weeks test...at least I WON'T!! I'm taking some ULRs on the Cruise with me...but I doubt I'll hear Georgia from the Pacific Ocean Side of Costa Rica ....which is where I'll be by then!! HHAHAHAHA...But...hey..I'll listen for it!!!

Ultralight Longwave DX-- One New NDB Station

Gary DeBock
 

Hello All,

It's been slim pickings for new beacons here recently, but finally a
new one was tracked down around local midnight-- 373-MF in Medford, OR.
Nothing rare or exotic, but it was the first new beacon received here on an experimental FSL antenna which was constructed a few days ago.
Current NDB totals are 145 stations in 11 states and 7 provinces-- with
lots of fun as a bonus!!

Now that they are closing down the LORAN service, all it will take is for some major solar storm to hit the satellites and we will all be in real trouble.

I would say +3dB coming from doubling the core. The other +1dB from
arising above noise-floor (Which is anon-linear phaenomen!!). If the
noise-floor would be infitesimal small, it would be not more than +3dB.

But it maybe just a measurmente uncertainly. Ferrite changed temperatur

BTW: A newer Loran-C antenna works with squared ferrite-rods.

Hi Graham -


But does Snelling cover a ferrite sleeve - this is very different ?!
As far as I remember, not specific.



I had this design worked out from new theory first - it was not just
some accidental discovery.
It looks like that almost all progress is made by accidental discovery
and then careful inspection of what have seen.



That is why I wrote my article, and if anyone says I am wrong then I
am open to reasonable theoretical argument, though not attempts to
shoot the messenger, or hiding behing qualifications, or unsound
prior 'reference works'.

I have received favourable comment too.
Then work on!



Henry, I've been in radio for 50 years, and electronics my only
employ too, thus I suggest you need to beware making assumptions
about whether this is worth 'writing home about' until you try it for
yourself.
Yes, that was my simple uneducated guess :-)



Simulations are only as good as input - can you run them for ferrite
sleeves ?
Simulation is just another tool along the soldering-iron. Imagination
another one.


I have not read anywhere about the losses I describe in my text which
cause the drop from initial permeability in rod antennas.
I think antennas work by compensating the external field with it's own
internal field. There is maybe an exception for field-measurement
devices like E-field JFET antennas.



There is no e-h field or EM wave - that again is how I was able to
come up with this design.
As far as I know, no construction known so far can directly couple to
the EM-field. An antenna always couple to one of the both fields. The
radiation field extends then to the EM-field (or back for an receiver).
So the true tranformation happens in the near-field.

If one knows of a true EM-field antenna, I would read it!


It has been thinking only of EM fields and magnetism in ferrite which
has prevented this type of receiving antenna from being designed, and
when you try one you WILL understand how we have been blinkered.

I can only encourage you to try one before making any claims against
it.

http://www.gmweb2.net/The%20FS%20Loop.htm
I'm time-bounded. So I wait for an scientific paper covering your idea,
including side-by-side comparable designs. I will read it will interest
and fun! Make one, please!

Re: New folder for FSL files

graham.maynard1
 

Hi Kevin,

I like your summary in the files folder.

FSLDesignSummaryDraft.PDF

Ferrite availability is likely to be different around the world, and thus we will not all be able to make the same final construction, but at least you have established an excellent basis from which everyone can make a start.

Cheers ........ Graham.
