Re: Litz wire

Rik
 

Not sure, just guessing, wouldn't three windings of smaller Litz take up more space than one of a higher count? Maybe not. -FARMERIK


Re: Litz wire

Will <will_k53@...>
 

Thanks Steve,

Seems logical but I wasn't sure.  Buy 100 ft of smaller wire and triple it, cheaper than either buying by the foot or having 2/3 roll "surplus"

Cheers,
Will.

Hi Will,
I've had an HP 4342A Q meter for a number of years and have done lots of tests with Litz. I would say that you should expect "near" results doing what you ask about. (The same can be achieved winding them in parallel, not twisted together, and connecting them at the ends, too.) I believe the main benefit comes from reducing the AC resistance, whether using in parallel or twisted.

When you use several litz wires twisted together does it work as if it
was that many strands in one.as regards Q and inductance? There would
be some difference in capacitance. What other effects/differences would

Take 3 200/46 wires. twist together then wind a coil, do the same
number of turns wound from 600/46 is it the same, near or nowhere near?

Use a good 40 watt soldering iron and good rosin core solder. Heat the Litz wire and start applying the solder, it will burn off the varnish and start taking the solder. Then wipe the wire with a rag and apply more solder and wipe again.

Re: 3 Inch FSL Tecsun PL-380 Model-- Construction Parts Required

Michael <michael.setaazul@...>
 

Thanks for the response, Gary.
When the construction details are available,
I guess I could try a mod of the unattached 3" FSL.
That would have the compensation of being able
to rotate the FSL whilst keeping the PL380 fixed
with the display best visible.

The downside here in Europe is that there are
ever fewer stations on AM. France and Germany
closed down MW over New Year. France may close
LW at the end of 2016. Germany already did so.

Other countries, including the UK, are scheming (sic!)
to follow suit... There just might be a re-think following
the flooding in the north of the UK. Digital services were
affected due to local power interruption, whereas AM radio
was able to continue coverage from further away.

If you are not planning to attach your FSL (and frame) directly to the PL-380 cabinet then
you can hook up almost any type of antenna that you wish to the circuit board connection points
(within the recommended inductance range of 180-450 uH) and presumably enjoy
increased sensitivity over the stock loopstick. The drawback of this approach is
that the combination would lack portability, one of the primary objectives of the 3" Bar FSL PL-380

3 Inch FSL Tecsun PL-380 Model-- Construction Parts Required

Gary DeBock
 

Hello All,
 
For those who would like to order the construction parts in advance for the 3" FSL Tecsun PL-380 project, I have attached a detailed photo showing the different items required for the model. These are:
 
1) Tecsun PL-380 AM-LW-FM-SW Receiver (available from many sources, including this eBay listing at $46.99 with free shipping to the USA)  http://www.ebay.com/itm/Tecsun-PL380-DSP-AM-FM-Shortwave-LW-PLL-Radio-Receiver-PL-380-/251783558999?hash=item3a9f783757:g:t0EAAOxylpNTTan7 
 
 
3) 8 Russian surplus 100mm x 20mm x 3mm ferrite bars (availability currently uncertain-- author has limited supply, but would prefer that an eBay source reappear for multiple orders)
 
4) 4" length of 2" diameter Fun Noodle inner foam core
 
5) Precut orange plastic antenna frame (cut from Ace hardware 36" plastic level, with 5" long bottom dimension and 4.5" top dimension-- cutting instructions to follow)
 
6) Rite Aid 1" wide waterproof tape (1 roll)
 
7) Scotch "Extreme" shipping tape (1 roll)
 
8) Tube of Duro Super Glue (or equivalent), .07 ounce
 
9) 6 inches of 1/8" diameter shrink tubing
 
10) Two 18" lengths of 125 lb. test plastic tie wraps
 
11) Two 16" lengths of 75 lb. test plastic tie wraps
 
12) Two 3/4" x 1" strips of 1" I.D. rubber heater hose
 
Because of the limited supply of the 100mm x 20mm x 3mm ferrite bars on hand, an alternative design using the plentiful Russian surplus 62mm x 15mm x 4mm ferrite bars is in the works. These will not provide the same level of MW sensitivity in a 3" bar FSL, but may be a fallback option for those who cannot secure the preferred 100mm long variety.
 
It is recommended that all interested hobbyists wait until the full construction procedures are published before starting the project.

Re: Foam noodles for 3" FSL

Hello Scott,
 
Thanks very much for tracking down these Noodles!
 
The 2" diameter Fun Noodles sold at the following link appear to be a direct replacement for the original inner cores of my 3" FSL PL-380 model :
 
I have placed a serious number of these on order, and we should shortly be swimming in Fun Noodles for anyone who needs them. For those who wish to order individually for the project, please use the link above (which will be referenced in the construction article).
 
Thanks again, Scott, and good luck in your 3" FSL PL-380 project!

Re: 3" Bar FSL Tecsun PL-380 Model-- 100mm Ferrite Bars

Gary,
 
Thanks for your long thoughtful reply to my e mail on new Ferrite Bar Antenna.  I can completely understand the problems with the supply issues involved now
that you outlined them.  It is way too early to talk about kits and having them installed by third parties, considering the difficulties which you stated.
Sometime in the future, if the demand is great enough, perhaps these obstacles will be overcome and  the things I mentioned may be possible, but I was
way off base to suggest them this early on.
 
You are doing a great job in pulling together the loose ends in the supply chains and your work is greatly appreciated.

It would certainly be great if someone had unlimited access to all the construction parts necessary to build the new 3" FSL PL-380 model, but unfortunately not even I am in that position. Interest and demand for this modified portable has been unusually high, causing a scramble for parts that are currently in short supply.
 
At the time of the 3" FSL PL-380's design the Romanian seller (Valtek) had been routinely offering the 100mm x 20mm x 3mm ferrite rods on eBay for many years, but he suddenly stopped selling them. There are apparently hundreds of these still in circulation somewhere in eastern Europe (with some of them already sold by Valtek and others) but with the murky situation in Ukraine and other eastern European countries nobody knows if they will show up again on eBay. I do have a limited number of them still on hand, but probably not enough to satisfy the current demand. There are currently multiple sources for 62mm ferrite bars on eBay, and although these would not provide the same sensitivity and performance as the 100mm bars in a 3" FSL design, I may need to design an alternate modification using these as a substitute in the future.
 
The Funnoodle situation seems to be more stable. My Kiwi buddy Tony King has tracked down a sizeable supply in New Zealand, and we are making arrangements to have them shipped to the USA. The diameter of these swimming floatation aides is critical for the project-- they must be somewhere between 2.25" (60mm) and 2.75" (70mm) in order to work in the project. At the time of the model's design I had only one Funnoodle of this size left over from the summer, and it has been mostly used up.
 
As for assembling the all the parts necessary to make this project into something like  a "Heathkit," it seems unlikely that anyone will have the time and resources to do that. I'm currently drafting "Heathkit-like" construction information with detailed photos and instructions, but I certainly don't have the time to act like a resurrected Benton Harbor company. Everyone who attempts the modification will need to depend on his own skill, experience and resources.

Re: Would anyone modify my pl 380 with the new antenna for a fee?

Rik
 

I can't help you, but have similar limitations. The PL-360 [and later versions which are not ULR's with SSB]  do allow you to connect an external loop to the radio without modifications. I just clip the leads from a multi coil Polydorof antenna to an 1/8th inch plug into the GP-5/SSB and the radio tunes the loop antenna. If easier, you may be able to make an air core antenna. I also use air wound Litz antenna coils from eBay which the radio tunes and they are very low noise. I expect a FSL would be better still, but it appears to be beyond my abilities to assemble. Good luck, I hope you find what you are looking for.- FARMERIK
