Jay, I'd love to get my hands on a TG-39 - but the cupboard has been bare on that for a LONG time, seemingly.  I keep looking on eBay and elsewhere, but it never comes up for sale.

HI Jay!

Agrree! But if you follow the thread to it's original message you'll find that I was answering a question whether the AN-200 was a suitable loop in combination with the Sony SRF-59 pocket receiver for "holiday-style" or "maybe-not-soserious-AM-DXing". I answered with my own experience of the AN-200 (I've got two of those, and I'm pleased with the performance vs. price).

For really serious UL-DXing I'm using a 7.5" x 12" FSL. A beautyful piece of equipment built by Everett Sharp. It did cost me an arm and a leg (plus one kidney for the shipping), but it was sooo worth every penny! ;) Everett is a fantastic craftsman and a very skilled carpenter/cabinetmaker, and the many hours he spent building this FSL made the total cost less important. This FSL actually looks like a piece of furniture, and when not in use, I have it on display in my living room! :)

Hans

Together with my CC Skywave, I received a pair of "CC Buds" - and I love them! Excellent earbuds!

They are retailed for US$12.95, according to the latest C Crane catalogue.

Hans,


While I agree that the AN-200/AN-100 loops work fine for this size category, they are pretty much equivalent to any of the many same size loops available, such as the Terk AM Advantage, The Degen TG39 or the now-discontinued Select-A-Tenna. The size pretty much dictates the amount of gain and they all perform so similarly on direct comparison that I'd say get whichever one you can find at the best price or which one you like the looks of. Here's a comparison review of some of these - if you want to build your own larger one the MTM Scientific is a nice kit and works very well...it is much larger and therefore more powerful. I've got a review of that one on the site as well.

Hi Erik!

Hi Erik!

Very interesting ideed! Maybe I should grab one of these DX-loops from PK-antennas before next season starts. Seems to be a good antenna. One can never have too many AM-loops in the shack... I just love them!

However, it seems that we have "slided" a bit off the original topic here, and I still think that the Tecsun/Kaito AN-200 is an excellent little loop that does what it's designed to do - and it does it very well! In my opinion it's the best little loop you can get, if you're on a tight budget - or just looking for a nice aid for your "holiday-style" AM-DXing.

I have both the medium and largest tuned PK AM loops. They have much more signal than the smaller TERK and Select-a-Tenna. It is pretty much as they say, the bigger the loop, the bigger the signal. The tunable  PK loops are advertised as being 'shielded', and they are more resistant to house RFI such as from the computer I use to help ID DX stations. Both can be within arms reach in my radio room, while the smaller TERK and SAT need to be farther away or I hear computer noise. The PK's are not hard to tune in either, and there is quite a peak on frequency. My impression is if you graphed the peak, it would look like an equilateral triangle. Adjacent frequency stations can be heard at greatly reduced signal levels, but the rest of the band is silent, and the very peak IS sharp enough to favour one station on the same frequency from another, much more so than the smaller loops I mentioned.  In my mind they would graph more like a  narrow sine wave. Many of my Litz wire loops tune so sharply I need gear reduction on the cap not to miss resonance. They would graph as a narrow spike which also narrows selectivity on all but the sharpest tuning radios with VERY narrow selectivity settings. Last count I am past 20 loop antennas here. - FARMERIK

Hans,

The two new FSLs that I am building will also be dual band, but only 7.5" dia X 7.5" long. They are all made, just need to wind the coils and tune. They will look just like yours, but smaller. 

Have fun with your FSL this fall.

Hi Everett!

The FSL is just awesome, and works amazingly well! I also found out that it's an excellent performer also in the longwave band, and your design with switchable LW and MW-coils is nothing but excellent. Been trying some Ultralight NDB-DXing with the FSL and my barefoot PL-310 and results, even now in the middle of the summer, is really promising! Can't wait until the beginning of September, when the real MW/LW season starts up here. This year, I will focus mainly on UL-DX, so I guess that the FSL will travel with me to my "DX-caravan" which is parked on the countryside in a very low-noise environment.

Hi Hans,

How is you FSL, that I sold you, working for you? I started building two smaller ones, but got side tracked on to some other projects, may finish them this winter.

Hi Marc,

Actually, I've been quite curious and was considering ordering the 50 cm "DX-loop" from PK-antennas, but maybe this is a bad idea?

I have no personal experience with the Sony SRF-59, but I'm the happy
owner of a Tecsun (Kaito) AN-200 passive loop antenna. This little loop
is a really good performer, inductively coupled to the ferrite loopstick
in a portable receiver. The antenna is very selective, has a very narrow
and good "null" and will give your little receiver a good signal boost.
I have logged a couple of All India Radio stations as well as
local/regional Chinese and Taiwanese stations on Mediumwave, using the
AN-200 inductively coupled to a barefoot Tecsun PL-380, a PL-310 and
Degen DE-1103.

The AN-200 also allows direct connection to a receiver's antenna terminal, but with somewhat reduced performance. I'm recommending inductive coupling to the internal loopstick in a portable receiver.

In my opinion, the AN-200 is a good and inexpensive entry level piece of equipment for ultralight DX-ing, and it's absolutely ideal for casual "holiday-style" AM DXing!

Here's a little hint: Also buy a "Lazy Suzan", and put both the radio and AN-200 on the device, find the "sweet spot" (best coupling between the AN-200 and the loopstick in your radio). The Lazy Suzan will help you to rotate the whole setup, and you will most probably find that the nulling characteristics of the AN-200 is nothing but amazing!

73's and Good luck!

Re: Participating in Japanese Radio Auctions

Rik
 

I really appreciate the original post making us aware of this service. I have a large collection of SONY radios never offered in the USA, and often have paid as much as 2/3 the cost of the radio to get it here from Australia or the Middle East and shipping costs from Japan seem quite expensive too. So I would not expect fees + shipping  to be cheap from a bidding service in Japan. Some ebay sellers in Japan do say on there Ebay Store to contact them about other Products sold in Japan, but I have not done that yet. In the EU, I believe there is a huge Tax collected on items sold, but larger sellers seem to be able to get around collecting  that when shipping to the USA, so prices with shipping seem like bargains. Some of my Radios came from CHUMS, a large dept. store in the UK, and there are others too. Roberts has quite a number of portables not sold here. A few are rebadged  Sangean radios, but many are unique. I have the Roberts Classic 954 which I like, and happens to be in view as I type.  Off the top of my head, I don't recall radios likely to qualify as ULR from Roberts, but I collect more in the 'lunch box' size range of entertainment portables. - FARMERIK

Oops... Sorry, I meant to type "Ultralight DXers" rather than IRCA members.

I agree with John about his comment on the high fees. The Jauce.com service is the same way. It's worth it though if they help you track down a radio that's just not available through USA sources.

Long Term Ultralight DXing Project - Comparing Different Locations

Paul Blundell
 

Recently we have moved house, as part of this I have ran a small side project where I have compared the average signal level of these stations at the two locations and then graphed them.

All stations were logged at around the same time of day over a few days at each location and then the signal levels were averaged and graphed.


As can be seen below the new location generally provides better signals levels with only 7BU on 558KHz and 7AD on 900KHz being noticeably worse at this new location.
