I found out ebay seller Mkmak222 does sell the 1162/46 litz by the foot. You have to order the whole spool and include a note in the order specifying length needed. He then refunds the difference back to your paypal account.

Litz for air core loops?

Rik
 

I have a 4 foot loop my son made for me wound for LW which I don't use much. I am thinking of having it rewound for AM and wondering if Litz wire would be better or sharper tuning?  I have the 15 to 386 or so cap with 8:1 tuning for it as well.

So far from reading in the files section here, it looks like Litz windings can be laid closer together and still have less capacatance, although my frame is wide enough for LW so I can space the far fewer AM turns out.

Would the length of the Litz wire be the same as ordinary wire in an air core loop? 

What would be the best Litz type for AM?

If I add a coupling loop for co-ax to a table reciever, should that be Litz as well or will that not matter?

My 4 foot loop is square, does it matter if a smaller coupling loop inside is square or round?

Puyallup, WA Ultralight TP's for 11-22

Gary DeBock
 

Hello All,
 
Believe it or not several Asian big guns sounded halfway alive this morning. Shaking off a 12 day slump the Japanese and Korean mega-stations led the revival, with 594-JOAK even hitting a fair to good audio level just after 1500.
 
At first check around 1400 it was already obvious that this morning would feature an improvement over the recent lackluster November propagation. 594-JOAK, 693-JOAB, 972-HLCA and 1566-HLAZ were all managing threshold audio, and 1593-CNR1 was close to doing so. There were even some moderate carriers on 603 and 738-- almost unheard of recently. These big guns generally rose up to fair levels in and out by 1430, and a late sunrise enhancement boost around 1500 gave additional strength to 594-JOAK and 1593-CNR1. Both of these diehards hit very brief good peaks around 1510 before collapsing back into the noise with the other Asian big guns. It wasn't exactly a thrilling session, but after the recent TP-DXing doldrums it certainly was a vast improvement.
 
73 and Good DX,

1010  MISSISSIPPI  WMOX, Meridian.  2235-2237 Good with ID and ad string.  10 November

1300  FLORIDA   WFFG, Marathon.  Noted at 0350 as an UNID running talk, rising out of the scrum at times, peaking nicely around 0355 with mention of Jim Bohannon show, into ads for Marathon area, then ID around 0400.  Fair signal  when it was in, though mixing with many.  13 November

1480  GEORGIA  WYZE, Atlanta.  Caught at 2206 with ID and slogan as "Atlanta's Gospel Voice", into African-American gospel programming.  Good on 11 November.

1520  FLORIDA   WXYB, Indian Rocks Beach.  Presume the one at 0045-0050+, with Greek programming including ads with 727 area code, good on 13 November.  Also:  0315 VG w/Greek music and Greek M ancr, 0328 with ads, including Kontas (?) market, ID at 0330.  Dominating Okahoma City and Buffalo. This on 21 November, so they're still at it. Though I'm only about 100 miles away, this 600-watter is probably getting out a fair distance since it has a pretty good signal at times.    Listed as 600w daytime, with an application for nights at 17w per NRC.  Worth checking.

1520  FLORIDA  Apopka.  WBZN.  2220 ads, ad for "Blue Darter sports" (assume local HS),  2225 ID and into syndicated "Powering America Radio".  Very good signal.  Looking for, but not finding, WXYB this early. 21 November

1540  IOWA  Waterloo-Cedar Rapids.  KXEL.  0255 with ads under Nassau,  ID by M at 0302 as "KXEL, The Voice of Panther Basketball", VG in ZNS null.  21 November.  Yeah, I know it's 50kW on a clear chanel, but it's yet another example of me doing so much of my prior MW DXing in an RF environment saturated with Cuba (or in this case, the Bahamas).  Back in the Keys, you would never hear WJR, WCCO, and WHO, let alone this one.    21 November

1570  FLORIDA  Auburndale.  WTWB, "La Raza", SP XE format, with ads for Bartow Ford and a doctor in Haines City, then ID.  2224-2227 all at local level during sunset skip.  21 November

Re: litz wire for FSL antenna

Gary DeBock
 

Well, Tony, having personally experienced the "propagation pipeline" between NZ and North America, I think that I'll go out on a limb-- and predict that your new Litz wire loop will work great!  :-)
 
Good luck, and if you need any other construction components, just give me a shout.

Re: 5" FSL Antenna Construction Project Update

Gary-

You have a good memoty, thanks.

Do you credit the sharp tuning more to the ferrite or the Litz. What would happen if an air core loop was made of the same Litz wire? How big would you guess it would have to be to compete reasonably well with this FSL?

Thanks- FARMERIK


Re: 5" FSL Antenna Construction Project Update

Gary DeBock
 

Hi FARMERIK,
 
Great to hear from you again!
 
<<<  Can a FSL antenna be used at home where there is some RFI?   >>>
 
Sure-- most FSL antennas are actually used indoors, and they provide good reception as long as you don't place them next to a computer, plasma TV or other heavy-duty RF polluter. Almost every home has some RFI issues, but you can minimize the problem by placing the FSL antenna away from the RF polluters, and close to an external window facing the desired direction of DX signals.
 
<<<   Is the pick up pattern on an FSL terribly narrow so it must point exactly toward a station?    >>>
 
No, the pick up pattern of an FSL antenna (like all figure-8 antenna patterns) is fairly broad, so unless you are close to a null direction (with the ends of the ferrite rods pointing directly at a station) you should get good reception. On ocean coast cliff sites I can direct the FSL's optimal reception at 270 degrees, and receive signals from both Australia (240 degrees) and Japan (300 degrees) at the same time.
 
What IS critical about an FSL antenna is the razor-sharp tuning adjustment. You need to be right on frequency for the best inductive coupling results, and this is why the 8:1 drive variable capacitors are so important. This high-Q tuning arrangement helps to reduce the splatter from off-frequency pest stations when you use it correctly, but it can also reduce the signal quality of the DX station if you don't carefully adjust the variable cap to an exact frequency match.

Not as successfully.  They are sensitive to RFI.  However, because of the cold weather I use mine 
indoors.  Just unplug as many appliances as possible, especially anything using AC/DC power 
adapters like the ones used with an iPad or iPhone. 

Good DX.

Thanks to Dan Sheedy for his ULR Shortwave Tip …Radio Impala……

robert ross
 

Hey Dan….Thanks for posting your ULR Shortwave Loggings from the Beach yesterday!! One of your logs was for the Clandestine Station RADIO IMPALA on 17540 Khz. They broadcast to RWANDA from the Talata-Volonondry, Madagascar Transmitters.

I needed that Clandestine Station for my Logbook…so I tried for them today….and I am currently listening to them from 1702 UTC Sign-on til now 1745 UTC. They are BLASTING in here @ 30 Over S9 Signal, with Talk in the Kinyarwanda Language after signing on with a Female giving S-on Announcements and a short Musical Interlude. Lots of mentions of RWANDA and Live Interviews. Hoping for a Nice Sign-off announcement too!!

Glad to add this one to my Logbooks…..Thanks for the Tip!!!

Re: 5" FSL Antenna Construction Project Update

I made the mistake of buying the 1200/46 litz from Canada last winter. I was unimpressed with the performance of my 5" FSL with that wire. It was slightly better than my select-a-tenna but worse than my 18" air core loop! So it sat on a shelf unused ever since. I should have listened to Gary when he said don't substitute litz. Live and learn I guess. If anyone wants to buy the remaining 62' of 1162/46 litz(the good stuff) for $50 shipped and insured(US only), please let me know.

November 8-10 Grayland, WA Ultralight DXpedition

Gary DeBock
 

Hello All,
After a rare opportunity opened up to get away on Veterans Day weekend an impromptu 3-day trip to Grayland, WA was made from November 8-10, providing a chance to test out the latest in FSL antennas and hot-rodded Ultralight radio gear. Because of the sudden decision to take off it was impossible to schedule a trip to one of the Oregon cliffs, resulting in my first visit to Grayland since a joint DXpedition with John Bryant in August of 2009. Lacking any ocean side cliff the flat beach at Grayland would not be able to provide the transoceanic signal enhancement and back-side signal rejection that seems to be typical at the Oregon cliff sites like Rockwork 4 and Cape Perpetua, but since my wife still had indelible memories of "that nasty one-star (Grayland) Motel," she absolutely refused to go along-- so I was able to cram my compact Toyota Corolla with three large items that could never be accommodated during our "family vacations"-- the new 17" MW DXpedition FSL antenna, the 12" Longwave FSL antenna, and the 30" loopstick Sony ICF-2010 SSB spotting receiver.
 
November TP propagation had been dreary at home, so DXing expectations were fairly low as I took the 2-hour trip to Washington's Pacific coast. By the standards of the current lean solar year the propagation turned out to be a mixed bag-- above average on the first morning (the 8th), below average on the second morning and somewhat in between on the third. Dicey weather on the last two days contributed to the challenge of DXing outdoors (at the picnic table near the end of Grayland Beach Road), with heavy rain and wind on the second day (the 9th) and a subfreezing wind chill on the third.
 
The first morning featured fairly good reception from Japan, Korea and China on the middle and high band, with 5 of the Chinese CRI stations being received (963, 1017, 1044, 1206 and 1323)-- the last three at very good strength. A mix of three TP stations was received on 1044, and Chinese stations on 936, 981 and 1593 showed up. The low band didn't seem to share much in the bonanza, though, with only 603-HLSA and 657-Pyongyang having potent signals besides the Japanese big guns. A fairly potent sunrise enhancement boost around 1500 brought up the signals of 954-JOKR and a few other second-tier Asians on the middle band, and 972-HLCA was still at an S9+ level well past 1600. The second morning turned out to be somewhat of a clunker, with both dreary propagation and weather combining to make the DXing effort pretty miserable. Propagation on the third morning was nothing to shout about, but the new 17" FSL was able to track down some TP mixes on 864 (HLKR and an UnID, possibly Japanese) and 873 (JOGB and a Chinese station). 864-HLKR was also received at good strength during the morning's freezing wind chill, as well as a weak Japanese-sounding station on 846.
 
Overall the weekend DXpedition was an enjoyable experience, with the new 17" FSL antenna tracking down some interesting DX despite nasty weather, solar flares and other distractions. Although exotic signals weren't really part of the expectations, proximity to the salt water did provide far more DXing variety and signal strength than watered-down inland propagation. For a DXer who had been bored chasing wispy signals from the big gun TP's at home in Puyallup, the impromptu weekend of ocean beach DXing was just what the doctor ordered.
 
The following stations were received on a 7.5" loopstick Tecsun PL380 Ultralight radio inductively coupled to a 17" FSL antenna at the end of Grayland Beach Road in Grayland, WA from November 8-10, 2014. MP3 recording links are given for most of the stations, and the TP stations which pegged the PL-380 S/N display at the 25 maximum at least one time during the MP3 recording are identified with a double asterisk (**).
 
531  JOQG   Morioka, Japan  (10 kW)   Anemic Japanese speech // 594 at 1315 on 11-8; low band propagation wasn't the best
558  HLQH   Daegu, S. Korea  (250 kW)   KBS2 deep-voiced male at weak level at 1520 on 11-10; barely strong enough 
           to confirm // with 603-HLSA  
**567  JOIK   Sapporo, Japan  (100 kW)   NHK1 interval music at strong level at 1423 on 11-10, // 594
585  JOPG   Kushiro, Japan  (10 kW)   Heard weakly at various times // 594 but never strong enough for a decent MP3 recording
594  JOAK  Tokyo, Japan  (300 kW)   Lack of potent low band propagation on 11-8 made this NHK1 big gun sound rather ordinary
603  HLSA   Namyang, S. Korea  (500 kW)   Very good level Korean pop music at 1240 on 11-8 hosted by KBS2 Korean female
           Pre-TOH fanfare by deep-voiced male, KBS2 network ID and 3 + 1 time pips at good level at 1500 on 11-8
603  China?   Believed to be the weak station under HLSA's female pop music at 1417 on 11-8; these two stations often mix 
639  China Synchros   Heard weakly around 1430 on 11-8, but too much KFI splatter for a decent recording
657  Pyongyang BS   Kangnam, N. Korea  (1500 kW)   Ancient martial music w/ Korean female tirade at good level at 1332, 11-10
          Good level Korean female speech with calm tone (not angry) at 1420 on 11-8 
666  JOBK   Osaka, Japan  (100 kW)   Received at fair levels on 11-8 // 594, but losing the battle with domestic splatter
675   NHK1  Synchros   At peak propagation around 1445 on 11-8 ghostly speech on this frequency seemed to be // 594
693  JOAB   Tokyo, Japan  (500 kW)   Fairly good signals through domestic splatter at 1415 on 11-8
702  NHK2  Synchros?   More ghostly Japanese speech on this frequency at 1450 on 11-8, but too weak to confirm 774 //
738  Radio Polynesie   Mahina, Tahiti  (20 kW)   Usually around at a fair level on all three days, but getting plastered by
           KCBS splatter. Lack of any cliff-provided splatter attenuation was most noticeable on this station, which usually stands
           out at the Oregon cliff sites
747  JOIB   Sapporo, Japan   Potent signals on all three days, but horrendous splatter from 750-Portland (much more so than
           at the Rockwork 4 cliff, only 75 miles from Portland) 
756  KBS   Yeoju, S. Korea  (100 kW)   Weak Korean speech at 1455 on 11-8, but never strong enough for a decent MP3.
           Tried at various times for CNR1 but it never showed up.
**774  JOUB   Akita, Japan  (500 kW)   Very strong signals on all three mornings but usually had serious Seattle splatter
           Solemn music and NHK2 sign-off chimes at 1422 on 11-9 (recorded inside the Grayland Motel Room 11 during bad Wx)
**828  JOBB   Osaka, Japan  (300 kW)   Very strong English lessons at 1248 on 11-10; better signals overall than usual
846  UnID   Japanese-sounding speech at 1353 on 11-10 but too weak to check the 594 //
864   HLKR   Gangneung, S. Korea  (100 kW)   Korean male speech at good level at 1527 on 11-10
864  UnID   Apparent Japanese-sounding station mixing with HLKR's music at 1347 on 11-10, but no real identity clues
873  China   Unknown Chinese station temporarily dominant over NHK2 English lessons at 1258 on 11-10
873  JOGB   Kumamoto, Japan  (500 kW)   Dominant over Chinese UnID with 3 + 1 time pips and English lesson fanfare at 1300
891  JOHK  Sendai, Japan  (20 kW)   Heard at weak level // 594 on 11-8 but never strong enough for a decent MP3 recording
918  China   Some weak Chinese heard on this frequency around 1410 on 11-8 but it quickly dove into the noise
936  China  (Anhui?)   Fair level Chinese female speech at 1408 on 11-8; only received on the first day
954  JOKR   Tokyo, Japan  (100 kW)   Good level Japanese male conversation late in sunrise enhancement at 1538 on 11-8
963  CRI   Huadian, China  (600 kW)   Chinese music and apparent Russian speech at fair level at 1533 on 11-8
**972  HLCA   Dangjin, S. Korea  (1500 kW)   Korean mega-station usually had excellent signals on all three days, with
           apparent immunity to any propagation drop off. Korean female music followed by Korean speech at 1429 on 11-8 
           Still at a blowtorch level for the 1600 TOH fanfare on 11-8; audible almost until 1700
981  CNR1   Changchun, China  (200 kW)   Fair-level Chinese female and male speech at 1412 on 11-8 
1017  CRI   Changchun, China  (200 kW)   CRI's Korean service at a fair level through some splatter at 1523 on 11-8
1017  UnID   Unknown station mixing with CRI's Korean female speech at 1523 on 11-8 (last 10 seconds of the MP3 recording)
1035  CNR1   Chinese Synchros   Poorly synchronized stations having echo effect during Chinese female speech at 1401 on 11-8
**1044  CRI   Changzhou, China  (600 kW)   CRI's Japanese service at a very strong level at 1356 on 11-8; this was the strongest
           signal that I've ever received from this station, and the first time that it's ever pegged the PL-380 S/N readout (at end of the
           MP3 recording) 
**1044  KBS   Samcheok, S. Korea  (10 kW)   Surprisingly, this lower powered Korean station was briefly dominant over CRI's
           music with Korean male speech at 1254 on 11-8, with the mix briefly pegging the PL-380 S/N readout 
1044  UnID   High-pitched, raspy-voiced female at weak level mixing with CRI's Japanese female and KBS' Korean male during
           the first minute of this MP3; no idea who it is, but the station only showed up during peak propagation at 1354 on 11-8 
**1053  Korean Jammer   Pegging the PL-380 S/N at full ocean coast strength at 1253 on 11-8; the strongest I've ever heard it
**1134  JOQR   Tokyo, Japan  (100 kW)   Very strong male-female giggling contest pegging the PL-380 S/N over a weak KBS
           at 1355 on 11-8; this station was one of the strongest Japanese signals over the entire weekend
1134  KBS   Hwaseong, S. Korea  (500 kW)   Despite its stronger power, this station was a poor second to the Japanese
           commercial co-channel all weekend long. Audible in the above MP3 with a serious male voice under the Japanese noise
**1206  CRI   Yanbian, China  (150 kW)   CRI's Korean service pegging the PL-380 S/N at an awesome level with male speech
           at 1527 on 11-8; the strongest that I've ever heard it during a DXpedition
**1287  JOHR   Sapporo, Japan  (50 kW)   Very strong interval music and Japanese male speech pegging the PL-380 S/N at 1518
           on 11-8; the strongest signal it's ever managed for me
1323  CRI   Huadian, China  (600 kW)   CRI Russian service at a very good level with female speech at 1250 on 11-8
1377  CNR1   Yingyang, China  (600 kW)   Heard briefly with male Chinese speech around 1400 on 11-8 but dived into noise
1503  JOUK   Akita, Japan  (10 kW)   Not one of the better Japanese performers, but usually at a fair level // 594 around sunrise
**1566  HLAZ   Jeju, S. Korea  (250 kW)   Overall, this was the second strongest TP signal during the weekend (after 972). Almost
           always pounding in at a blowtorch level, here is was pegging the PL-380 S/N with its Japanese service during the nasty
           weather at 1325 on 11-9 
**1575  VOA   Rasom, Thailand  (1000 kW)   Female Asiatic language speech pegging the PL-380 S/N at 1446 on 11-8
1593  CNR1   Changzhou, China  (600 kW)   Male Chinese speech at good level in and out at 1440 on 11-10
1593  NHK2 Synchros  NHK2 Chinese lessons mixing with CNR1's Chinese speech at 1445 on 11-10-- sounding like two Chinese
           stations on the frequency 
 
73 and Good DX,

Hi Ryan,

Since I have never used this 1200/46 Litz wire for any antenna project I can't really make any recommendation one way or the other. However I have heard many warnings from the crystal radio group to STAY AWAY from the bright-colored Litz wire sold from Canada.

My own recommendation for the highest-sensitivity Medium Wave Litz wire currently on the market is the 1162/46 Litz wire sold by the eBay seller Mkmak222, at the following listing. This is the Litz wire that I have used for all FSL antenna projects since April of this year (the dual-coil 12" model, dual-coil 15" model and dual-coil 17" model), and it works extremely well. Using it in the 5" FSL project (instead of the 660/46 Litz wire, called for in the original article instructions) should provide a significant boost in MW sensitivity for the 5" FSL antenna.

Thanks for the litz wire recommendation Gary. The problem is I only need 37' out of the 100' spool. I wish he sold it by the foot. Does anyone want to buy the remaining 63' for $50 shipped/insured(US only) from me after I buy it? That's .18/ft cheaper(.79 vs .97) than ebay. Here's the link Gary provided>

Hi Phil,

When the FSL construction craze started in early 2011 (after the late Graham Maynard's introductory article) there was a great demand for the larger-diameter Litz wire, which provided the best sensitivity. Unfortunately the Ultralight radio loopstick tinkerers (like me) had no experience with this huge Litz wire, which was too big to fit on radio-sized loopsticks. We depended on the advice of crystal-radio enthusiasts like Steve Ratzlaff, who had a lot of experience building the highest-Q crystal radio antennas using this large Litz wire. The warnings from this group were all the same-- stay away from the bright-colored Litz wire sold by the eBay seller in Canada, and go with either Ming Mak's Litz wire from China (the best value for the price), or some of the USA-made Litz wire sold by Dave Schmarder. As for the reasons why they found the bright-colored Litz wire from Canada unacceptable, I really can't tell you. Maybe one of them will read this, and provide further information.

Hi Ryan,

Since I have never used this 1200/46 Litz wire for any antenna project I can't really make any recommendation one way or the other. However I have heard many warnings from the crystal radio group to STAY AWAY from the bright-colored Litz wire sold from Canada.

My own recommendation for the highest-sensitivity Medium Wave Litz wire currently on the market is the 1162/46 Litz wire sold by the eBay seller Mkmak222, at the following listing. This is the Litz wire that I have used for all FSL antenna projects since April of this year (the dual-coil 12" model, dual-coil 15" model and dual-coil 17" model), and it works extremely well. Using it in the 5" FSL project (instead of the 660/46 Litz wire, called for in the original article instructions) should provide a significant boost in MW sensitivity for the 5" FSL antenna.

Hello All,

Asian propagation must have gone south to Arizona this morning, since no TP audio managed to show up here in Puyallup. It was almost a complete clunker session, with only a ghostly carrier on 1053 just prior to 1500 UTC. Fortunately there are some recent Grayland recordings here to enjoy, as somewhat of a substitute for comatose TP propagation (as Nick and Bruce also seem to be doing :-)

Hello All,

For Ryan Martin or any others who plan to construct one of these 5" FSL antennas this winter, there is some updated information that may be helpful.

The original 5" FSL antenna construction article ( http://www.mediafire.com/view/9ze98h293s85p86/5%20inch%20FSL.doc ) was written in February of 2012, and has been downloaded almost two thousand times from the MediaFire site. A demonstration video of this 5" FSL antenna is posted at http://www.youtube.com/watch?v=A1gfUeoQhHQ

1) Because of the purchasing demand for the 140mm x 8mm Russian surplus ferrite rods called for in the article (and also called for in the 7" FSL construction article) the Ukrainian eBay sellers have raised their prices many times for these rods, taking advantage of the many hobbyists who have ordered material for these projects. This has driven the cost of purchasing these ferrite rods far above the original (February 2012) price, which in turn has driven the construction cost of the entire project above the original $95 target

There is nothing magical about the 140mm x 8mm size of ferrite rods called for in the article! A very reliable eBay seller is offering 125mm x 8mm ferrite rods at less than half the price per rod ( http://www.ebay.com/itm/Small-balun-ferrite-rods-8x125-mm-Lot-of-50-/400706626766?pt=LH_DefaultDomain_0&hash=item5d4bf9e4ce ) and the FSL performance difference between the two sizes of ferrite rods would be negligible. Save yourself some serious $$ by purchasing the 125mm x 8mm ferrite rods, and simply add a couple of extra Litz wire turns to compensate for the slight difference in ferrite rod inductance.

2) Since the February 2012 article was written some new, higher diameter Litz wire (which provides more FSL sensitivity) has been introduced on eBay by Mkmak222, a very reliable seller. My recommendation is to go with the new 1162/46 Litz wire instead of the 660/46 Litz wire called for in the article. This higher diameter Litz wire (available at http://www.ebay.com/itm/Type-2-Litz-wire-1162-46-AWG-100-feet-/151156887668?pt=LH_DefaultDomain_0&hash=item2331a71074 ) will provide a significant sensitivity boost for your 5" FSL antenna. Bear in mind, however, that since this new Litz wire is of a higher diameter than the 660/46 wire the resulting FSL coil will be significantly wider for the same number of coil turns, spreading out to cover the ferrite rods to a much greater degree. The same number of coil turns should be used as called for in the article, however (26 for the 140mm x 8mm ferrite rods, but 28 if you use the much less expensive 125mm x 8mm ferrite rods).

3) The supplier of the "N50P" variable capacitor (Crystal Radio Supply) is no longer in business. An acceptable substitute for the variable capacitor (of almost the same size and construction) is the "365-8-1" offered by the Midnight Science crystal radio parts suppliers at http://www.midnightscience.com/catalog5.html#part3

Good luck to all who are considering the 5" FSL project!

Re: litz wire for FSL antenna

Hi Phil,
 
When the FSL construction craze started in early 2011 (after the late Graham Maynard's introductory article) there was a great demand for the larger-diameter Litz wire, which provided the best sensitivity. Unfortunately the Ultralight radio loopstick tinkerers (like me) had no experience with this huge Litz wire, which was too big to fit on radio-sized loopsticks. We depended on the advice of crystal-radio enthusiasts like Steve Ratzlaff, who had a lot of experience building the highest-Q crystal radio antennas using this large Litz wire. The warnings from this group were all the same-- stay away from the bright-colored Litz wire sold by the eBay seller in Canada, and go with either Ming Mak's Litz wire from China (the best value for the price), or some of the USA-made Litz wire sold by Dave Schmarder. As for the reasons why they found the bright-colored Litz wire from Canada unacceptable, I really can't tell you. Maybe one of them will read this, and provide further information.

Any reason why its NOT recommended... performance , construction, stiffness etc?
 
BTW - I got my wire and ferrite rod, now just have to put my LW antenna together...
Service was great on both orders
