Thanks Paul,

I'm happy that you are having fun with the new 3 inch Baby FSL!

For those wondering what this new antenna design looks like and how it performs, Paul's FSL was the one chosen for a YouTube signal-boosting demonstration posted at https://www.youtube.com/watch?v=JZtYli09mTg

Stephen, Paul, Jay, Vimal and Dennis,

Thanks you all for your comments on the Innovative Ferrite Antenna article, which are much appreciated!

Stephen, when I first saw the view of the Pacific from the Rockwork ocean cliff in Oregon, it reminded me of seeing the Pacific from the window of a 747 Jumbo jet 30,000 feet above the ocean :-)

I couldn't resist driving up and looking over the cliff edge, which surprisingly hasn't been fenced off despite the danger. And it wasn't long before I was pushing my luck way past the breaking point by setting up FSL antennas on the cliff edge at 3AM, wondering what this awesome location would provide in the way of transoceanic results. It didn't take long before I was routinely tracking down various New Zealand stations that had never been heard at Grayland over three decades-- including some that have still haven't shown up with even a trace there.

The transoceanic DXing advantages of rich farm soil have been proven over and over both in our Ultralight group and among spectrum capture DXers. At the IRCA convention I finally had the chance to meet Nigel Pimblett, an awesome DXer from Alberta who gets outstanding Australian results with his Perseus-SDR and broadband arrays on rich farm soil. Some Australian stations like 585-2WEB tell me that the strongest recordings they have ever heard of their signals come from my FSL's on the Rockwork cliff, and Nigel's broadband array in Alberta. When Nigel and I finally met each other it was like two long lost friends, who shared a special bond despite using radically different antennas and locations. Great fun! :-)

73, Gary

Today I had a small amount of time to test out my new 3" FSL aerial (Thanks to Gary). This was a mid day session in the middle of town, I called past a local park during my lunch break and set myself up on a picnic table. 

 

As my time was limited, I didn't get to spend as long doing this as I would like but I was able to start to learn about some of the amazing features of this aerial and the best way to place / tune it. 

 

My testing so far seems to suggest that having my Teach PR130 leaning against it (as shown in the below photo) produces the best results.

 

I logged a few stations on various frequencies, the below are a few standouts.

 

531 - 3GG (Warragul)
5000W 
380km:
While I am often able to hear this station during the day, adding the power of the 3" FSL aerial takes a noisy signal to a whole new level with my TEAC PR130 struggling to handle the large increase in signal level.

 

585 - 7RN  (Hobart) 
10000W 
168km:
This is one of my "check" frequencies, a low 1 -2 signal level gets blown up to a strong 5 with this added to the mic.

 

1323 - 5DN (Adelaide)
3300W 
1040km:
Another station that I often check but struggle to hear during the day, the 3" FSL aerial brings a signal out from the noise that while not very strong, is well worth listening to.

 

1584 - 7SH (St Helens) 
100W 
95km:

This was a bit of a last minute check, a totally absent signal jumps out when the 3" FSL aerial is added.

Subject: [UltralightDX] Ultimate Portable Ultralight Radio DXing Go Case - September 2019

I have been looking for a way to carry my portable radio collection and my other ultralight related items. I have used a variety of bags and cases in the past.
Recently I was out doing some shopping when I called passed my local Super Cheap Auto. Here I found this case on special for $22, I decided to replace my previous case as I found it was not working as well as I would have liked and as it didn’t keep the radio the right way up it added the risk of the aerial breaking off. I have also recently been sent a baby 3" FSL aerial which I wanted to carry and protect.

Last night I had some spare time so I sat down and set up this case. I cut some small pieces of timber to hold the aerial in the right location and added some thin MDF to divide the aerial section off from the front part where I will be storing my radios.

Overall, I am very pleased with how well this case has come out, I am able to carry and store my baby 3" FSL plus two small radios plus log sheets, pens, notes, spare batteries and ear phones, everything I need for portable sessions. It is also small enough to fit in my back pack.

While this case was designed for ultralight DXing the same ideas could be used for amateur radio, radio scanning or any other storage need.

Re: SPMcGreevy "OFSL" (open FSL) loop test-results and photos

Thank you guys for the nice input. I am from VU Land and am planning for one Indian ocean island dxped in February 2020. I have collected a small horde of ferrite rods and other hardware for construction of two to three of Gary's FSLs. But I must get the suitable Litz wire rolls and air dielectric variable capacitors. Can you guys kindly help me by pointing to sources for these materials? So far as air dielectric variable capacitors are concerned, I have in my collection ganged capacitors from AM Radios or large transmitting capacitors with suitable values. But they will increase the luggage weight. Hence, I would like to have single section air dielectric variable capacitors instead.
Thanks once again and kind regards,
73 de Sudipta VU2UT.

Re: Innovative Ferrite Antennas Article

Oh yes, regarding flat-land/fertile soil DXing locations, during a long road trip and DXpedition I made to Manitoba, Canada - and all the way back westward to BC in September 1993, I rolled out a few end-fed wires in remote farm-fields where I could park for the night in my camper-van, and I was astounded at the strength and numbers of hets from the 9 kHz "splits" and caught some audio from a few DU stations too.  Also, in the evenings, some TA signals on MW and LW were audible with fair signals (the usual big TA sigs) - the 198 BBC signal was a telltale "wavery-carrier" (their phase-shift carrier time signal) and would appear by sunset.  I knew this all was due to the very flat-land terrain (low-angle skip!) and high-conductivity soil to boot.

In August 1996 from west-central Manitoba, during a combined "Natural ELF-VLF radio" recording expedition and LF-HF DXpedition, I rolled out a long, maybe about 1200-foot long "Beverage" wire pointed north-east (very arduous to do so in the thickly treed and boggy land there near Grass River Provincial Park but I could get it elevated a bit off the ground), and the TA's blasted in nightly, especially one evening - 30 August 1996, when the auroral-oval had "retreated" far southward, leaving TAs skipping into the "hole" of the oval thus the strong receptions.  The proximity to Hudson Bay and also the very flat terrain there made it somewhat like being by the seashore!

Marvelous article, Gary!  What a lovely pic of your cliffside (Oregon) DXing site and the very blue sea -  I can hear the singing hetrodynes now!  Way back in the early-mid. 80s when I rolled out long (1100 ft. / 330m) Beverage antennas from a tent-DXing site atop Mount Vision (Inverness Ridge) in the Point Reyes NS - Marin County, Calif., the additional altitude of 1100 feet above sea-level (thus a much greater view out to the distant horizon) really ENHANCED TP DX - especially DUs and Hawaiians, compared to the near sea-level beachside DXpeditions.  It is possible the much farther-view of the horizon allows for the really low-angle "combined constructively-phased groundwave-skywave" effect to occur - TP signals would stay in post sunrise for longer periods compared to the near-sea level sites at Abbotts Lagoon and North Beach (all within Pt. Reyes National Seashore).  As such, I think that really FAR OUT horizon view in your photos in this article is also an added factor WHY TP DX is so superior there (as it was atop Mt. Vision for me).

73 and thanks a lot!,

SPMcGreevy "OFSL" (open FSL) loop test-results and photos

Stephen P. McGreevy
 

It has been a few months since I reported on the results of what I now call my “OFSL” or “Open Ferrite Sleeve Loop” that I had constructed around a 16 oz. / 453g size Folgers “Classic Roast” plastic jar, in that the six 200mm (R40C1 type) are not adjacent to each other as I have seen of Gary’s designs, but are widely spaced around the jar (I had only ordered six of the rods for initial testing/experimentations).
The OSFL loop - previously I’d dubbed “the Ugly Duckling FSL”  - employed an external (and large/heavy) old Soviet 60-600 pF var. cap. that is designed for transmitting with widely spaced rotor/stator plates), and it was rather “kludgy” to rotate easily.
It occurred to me that a smaller open-air var. cap. could be mounted inside the jar’s red lid along with a small SPDT switch to switch in the off-center tap of the Litz winding and some fixed “padding” caps of about 330pF.  As such the loop is “dual-band” and goes down to about 340 kHz just incase I wish to use it in the upper NDB band and in the former Maritime segment (430-510 kHz).
The result(in the photos) is a very robust and quite water-resistant OFSL that is lightweight and marvelous for taking on Expeditions - even just into a knapsack as I walk out of my small town into a noise-free location.
In-yard comparisons with a considerably larger air-core “diamond” loop find that the OFSL has vastly higher-“Q” (sharper tuning) and it also has higher-gain than the larger stand-mounted diamond open loop due to its larger induction-field and the advantages of Litz wire.
I can’t wait to take this on a flight to Hawaii (maybe this November 2019) on a DXpedition tentatively planned in a similar fashion to Gary’s Kona (Big Island) Hawaii DXpeditions.  
Include a couple of photos for presentation here.  The OFSL makes AM stations with “barely audible audio” in the daytime to clear/clean copy provided there is no local noise nor QRN (such as 740 KCBS, 620 KIGS, 1070 KNX and many others).  Tests were made with one of my two trusty Sony ICF-SW6700GR portables.  I can imagine with a modified ultralight portable with switchable pass-band filters, this would be even more superb for coastal DXpeditions!

For the benefit of those who cannot attend the IRCA convention in Seattle, an 8-page article has been written detailing the recent innovations in ferrite antennas, including the latest "supercharged" travel portables and the airport-friendly FSL models demonstrating superior performance on exotic overseas ocean beaches.

The article details the four types of antennas offering four levels of ferrite antenna gain, and also four different types of DXing sites offering enhanced propagation for superior results with ferrite antennas. This is the same outline as the speech that will be given at the convention on Saturday, although the article contains additional photos and links  https://dreamcrafts.box.com/s/kp487ahn3wm3dd7rkb6thvddyt7wixgb

For those who can attend the convention on Saturday there will be a chance for "hands-on" daytime DXing with these ferrite antennas in the afternoon (weather permitting), including the 17" diameter Monster FSL (the world's largest, heaviest and costliest :-) Hope to see you there!
