Hi Paul.
Iv'e heard 2LT here in Melb fairly audible after 11.00pm at night. Now I know which one was always fighting with 7AD when that was on MW. 
On 558 6WA could always be heard late at night here too as it was easy to null out 7BU. 4GY may be more of a challenge but I'll be listening for it. 
Any news about 7SD 540KHz moving to FM? 
Cheers. Dan.

Hi Paul. I think you'll like the AR1780, Iv'e had a lot of fun with mine, On MW it is more sensitive than the PL-660 I have. 
Cheers. Dan.

Thanks for posting this.  It is great to see and hear about your testing.

Next I wound about 45 turns of the Litz wire - all of it (60feet/~17m) on the form, and initially taped the windings down, but I made sre to make a tap at about 2/3rds of the coil (or 1/3rd - approximately) so I could select either the ends (1 and 3) or 1 and 2 or 2 and 3 - "2" being the tap point.

1 to 3 (entire loop) came to ~380 uH.  The winding to the tap (2) 1-2 were 118 uH; and 2-3 was ~260 uH approx.)

And I came up with my "McGreevy quasi-FSL ugly duckling loop, and you all know what - an initial check-out using a "Soviet" 60 to 615 pF var. cap. and my older well-traveled Sony ICF-SW7600GR had amazing and VERY hi-Q of a few stations I checked (daytime reception at about 09:30 PDT here in Keeler in eastern, California).  Hi-Q totally blowing Q levels compared to my open-wound diamond loop in the shop building - gain" due to its larger induction-field was wonderful!

338 RYN Ryan/Tucson NBD fine carrier and ident; 540 Tijuana solid / 560 KSFO SF fair-poor but copyable / 740 KCBS SF near perfect reception with KBRT so. CA nulled.

WOW!  The Q is so high that is auguments the Sony's modest-selectivity- it is very noticeable!  I truly am amazed, and seeing and DXing is now believing, gentleman!

I can only imagine how a full-sized Gary-style loop at the OR-Cliffs with big land-attenuation to the east there/Hawaii/DX lands would perform if my "ugly loop" (well I covered it all up with the black tape afterwards).

Wow! Attached  (if OK) are some photos... just a basic starter "quasi-FSL" but now I am convinced - lightweight and totally portable for transport, yet very hot performer.

Thanks for all fellows!  73 for the mo,

Who Is Tassie Radio Rxer?

Paul Blundell
 

I live in Launceston Tasmania, a city of around 68,000 people. I have always had a passion for radio and anything technical. Over the years I have moved between a few different areas of the radio hobby:
UHF CB
Amateur Radio (Ex VK7FPGB)
Radio Scanning
Ultralight DXing
Shortwave Listening

Recently my passion for radio scanning has been lost, we have had a few users move to DMR and other digital modes. Combine this with the poor public image of radio scanning and my own lack of passion for it has seen my return to a different side of the radio hobby, this is a focus on the RX side of the hobby. This includes:
Mediumwave Broadcast Band RXing
Long wave RXing
Shortwave RXing
VHF FM broadcast band
VHF air band

My focus is on any signals I can receive, not just DXing. For me it is just about logging any frequencies I can hear, if a signal is a low power signal from 10km away or a high power signal from 5000km, it makes no difference to me. This is why I refer to what I do as RXer, not DXer.
I am in the process of sorting and updating my files, I need to post a lot more content to my new blog (URL below) as I update it, I decided a fresh start required a clean blog with a slightly different approach to what I post.

Re: My first 6-rod quasi-FSL built 08-09 April and it really is HOT and very Hi-Q!

Stephen P. McGreevy
 

Additional thoughts: Please pardon my typos. If I find a var. cap with less minimum-capacitance than the big Soviet (transmitting) one (maybe 10-15 pf - and I have a few air-core ones purchased from an HK seller), it would resonate to the top of the MW-BCB, rather than 1420 kHz (or so) max.  Goes down to 315 kHz, so good for NDB DXing also.  Steve

Tasmanian Changes

Paul Blundell
 

Some recent changes here in Tasmania.
558kHz - 7BU: Now moved to FM, this means 4GY and 6WA are DX targets on this frequency.
900kHz - 7AD: Now moved to FM, this means 2LM and 2LT are now DX targets on this frequency.

Ultimate Portable Radio Kit - June 2019

Paul Blundell
 

This case is one that I have had for a few months, it has been used in a few different ways. Firstly, it was used with my radio scanners and then for storage at home.  It was purchased from Super Cheap Auto for $12.

More often these days I am carrying my radios with me, due to this I wanted to provide the best possible protection for them. Last night I had some spare time so I sat down and set up this case. The main thing was making sure my radios were protected the best way possible. I build a frame out of cardboard and foam to protect my 7.5" loop stick PL380, wrapping this up with a great level of protecting around it, I then cut this to the correct height for this case. I added some thinner foam to the bottom of this. I then installed this in to the case with some doubled sided tape on the bottom and back, the front is secured with some tape to hold it in place. This also helps to protect the other bits and pieces I have in the radio case. My Digitech AR-1780 fits in to a small neoprene case, these are designed to hold a small tablet. I have enough spaces for my ear phones and some spare batteries.

Overall, I am very pleased with how well this case has worked out, I am able to carry and store my ultralight radios and everything I need for a portable session. It is also small enough to fit in my back pack. While this case was designed for my ultralight radio kit, the same ideas could be used for other areas of the radio hobby.

<<<   I just received a batch of litz wire and a batch of ferite rods from your group's recommended seller for these items on eBay.  gary's receptions in HI are wonderful/like his DX at the Clffs in Oregon!   >>>

Thanks Steve,

Your comments are appreciated-- and I think that we have only scratched the surface in Hawaii!

<<<    As a former Point Reyes NP DXer (former Marin County resident and native until 1996 escape to less expensive locale here) rolling out Beverges in the early 80s at Point Reyes (North Beach and Mount Vision) and then in Hawaii (alone in my car with long 1100 ft. Bevs on the Big Island or DXing at good friend Dr. Richard E. Wood's home QTH too), it was really cool to DX the now gone Oceania Island stations (1188 Wallis for example! - etc. etc.).   >>>

Yes, I have also been inspired by Richard's Hawaii loggings since I was a teenager in 1969. He would routinely report reception of graveyard stations from all over the USA. Shortly before he passed away he sent me a long, handwritten letter expressing serious interest in our new (at the time) Ultralight radio group.

<<<   Gary's more recent DXpeds. in 2015 onwards PROOVE the FSL's superior DX capabilities to the maximum!  Therefore, I will construct a similar style loop and maybe can get to the coast out of this deep Mojave Desert locale for some top-notch DX like you FSL using dudes do at the OR coast and abroad or in Hawaii!  Kudos! And most importantly, big THANKS for your input for all of the MW DXing community globally!   >>>

Actually, Steve, we are having the thrill of our lives developing these hot little new antennas, and using them for exotic DX around the world. Nobody needs to thank us for having such a blast! Even in a "worst case scenario" place like Hong Kong (with which you are very familiar), if an FSL can't be conveniently deployed, a 7.5" loopstick will provide some "supercharged" DXing excitement (Africa, Eastern Europe and the Middle East). I'm just hoping that the Commies in Beijing don't ruin the place before a return trip next April.

73, Gary

     


Re: New Design (2019) FSL Antennas

Interesting development!

Has anyone tried an FSL for the 160m amateur radio band?

Where noise is a problem on 160m, a remotely tuned FSL might make
a big difference for reception, obviously switching to another aerial
for transmission.

Thanks Tony,

That article is interesting indeed-- Kiwi ingenuity at its finest!

For those of you who have ever desired a remotely tuned FSL system and/ or a 50 ohm output to use an FSL with a communications receiver, Bill's design is awesome-- and highly recommended!

Thanks Gary,
I thought I read a few months ago that you had some of these. Just a faulty memory I am sure. Steve R. wrote me offline and sent me a link. Thanks Steve!!  I ordered a couple of what I think are the correct parts.
This is the description:
384pf Air Variable Capacitor with 8:1 planetary reduction drive

I will be interested to see what the differences are with my 7" FSL. Is there anything else I need to do other then just swap the part. I would not think so, but figured I would ask.
Thanks for the reply!

Sorry for the radio silence from my end, I have taken on a new role at work and as such have had less radio time. 

The upside is I now have a new AR1780 which I am  super keen to explore the bands with.

Hi Gary,
Looking forward to the trip very much and some serious dxing.

73 and good dx to all!

Your comments (and efforts as Moderator) are always appreciated. If you can send me your latest mailing address in Tasmania, I'll see if I can send off one of the latest compact FSL's Down Under.

Re: New Design (2019) FSL Antennas

Gary DeBock
 

Thanks Craig,

Your comments are appreciated, but a lot of the early progress with the "Frequent Flyer" FSL antenna was related to your own transoceanic DXing success, especially your breakthrough Princeville, Kauai trip in April of 2017. The awesome Asian recordings on your open-air iPhone videos were enough to convince anyone to make the dream DXing trip of a lifetime, and head for Kauai!

This November we should have some serious DXing fun in Poipu, with four highly motivated participants, an in-house DU English translator (Chris from Melbourne), four of the razor-sharp tuning 5 inch FSL's and four continents to go after (all of Asia, Oceania, and North & South America). Of course that won't stop us from going after the big guns in Europe and Africa if we have half a chance :-)

73, Gary
