Quick question about the latest FSL antennas for the PL-380

ku4a@...
 

A friend of mine and I here have started pulling together the parts needed for the FSL antennas. We both have PL-380s.


I have downloaded construction articles for the 3-inch and 4.25-inch FSLs. On hand, we have the 2-inch pool noodle (fits the 3-inch FSL) and 20 of the "common" ferrite bars (62mm X 12mm X 4mm) (22 required for the 4.25-inch FSL). We also have a good quantity of 250/46 Litz wire, and have already done some "practice" tinning/soldering.


Is it possible to build the 3-inch FSL with the "common" ferrite bars? If so, it would probably require 20 or less, and we have the pool noodle on hand. If we HAVE to go to the 4.25-inch FSL, then we need more "common" ferrite bars, and a bigger pool noodle.


I can imagine that there are performance difference between the two. But either one will be a great antenna for us. So, in summary, am wondering if the 3-inch FSL can be built with the 62 X 12 X 4 ferrite bars. 


Thanks!

Re: 3" Bar FSL on a Tecsun PL310

Hello Gregory,
 
<<<    I had the right Litz on order but did not want to wait. It came today so I built the antenna as per spec, connect to my Tecsun PL 310. Works very well - in fact I'm listening right now to CBC Radio One, AM 990 CBW in Winnipeg, MB, a distance of 1029 miles. This with a local AM 990 station I am able to null almost silent.

I'm Impressed.   >>>
 
I think you'll be happy that you modified your PL-310 model with the recommended 250/46 Litz wire, Gregory-- already five of these FSL-powered Tecsun radios are providing astonishing DX around the world. You are the first to successfully complete such a transplant on the PL-310 model, though-- congratulations.
 
Of course the 3" FSL transplant modification will work great in any of the Tecsun DSP radios-- even the CR-1000 full-sized portable. It would be nice if Tecsun offered it as an option on the PL-380 and PL-310, but I'm not holding my breath.

An Even Wilder 1593-CNR1-NHK2 Mix

Gary DeBock
 

1593 kHz was the scene of a wild S9 mix of CNR1 news and an NHK2 radio drama for an extended period this morning on the "barefoot" 3" FSL Tecsun PL-380. This 90-second segment was recorded from 1537-8, during which the bizarre NHK2 radio drama mixes with the male Chinese speaker to create a spooky, Halloween-type atmosphere

Micro BOG?

Rik
 

I have been looking Online and many sites refer to work done by n4dj with very short BOG antennas 220 feet long. If they work, it would open up use of BOGs to many more people. Does anyone here have a working link regarding such short BOG antennas?

I just tried to email n4dj and I  see CRB Canada sells a 200 foot Beverage kit, so some how this can work.

I do use a 500 foot unterminated BOG and it helps my Log entries adding stations off the ends I never logged before. - FARMERIK

Hello All,
 
Very good high band conditions prevailed here this morning, featuring strong signals from both 1593-CNR1 (with a slight echo effect) and the NHK2 synchros (with a radio drama) during sunrise enhancement. This wild S7-S9 mix was on the "barefoot" 3" Bar FSL Tecsun PL-380 Ultralight this morning at 1439

2 1/2" Ferrite Tube for 3" FSL

Everett N4CY
 

If anyone is interested I just made up a ferrite tube using 10 of the Russian bars that are 5" long. The outside dia is 2 3/8". This should work fine for Gary's 3' FSL. The price is $50 for it and I will pay the shipping in the lower 48. If anyone is interested please contact me at everettsharp@... and I can send a picture. All it would need is the Litz wire and some PE foam to cover it.

"Star Wars" Shootout-- Sony ICF-S5 "Superstar" Vs. "Science Fiction PL-380"

Gary DeBock
 

Hello All,
 
The Sony ICF-S5 classic portable from 1980 has the reputation of being one of the most sensitive AM-DXing portables ever manufactured. Roughly equivalent in sensitivity to the Panasonic RF-2200, it was the Japanese-market equivalent of the legendary ICF-S5W portable-- which usually commands hundreds of dollars during the rare occasions when it is offered on eBay. Back in 1980, the ICF-S5 was marketed in Japan by Sony with the nickname of "The Superstar."
 
The all-new 3" Bar FSL Tecsun PL-380 model has its own advantage, however-- a transplanted FSL antenna enhancing its own AM sensitivity up to a phenomenal level. Of course it also has DSP selectivity, 500 memories, multiple digital search functions and other 21st century refinements-- but such concepts were only "wishful thinking" back in 1980.
 
See how these two awesome AM-DXing portables shake out in the daytime DX reception of 1070-CFAX (10 kW at 99 miles) in the new video posted at https://www.youtube.com/watch?v=VY9u8MReGjk&feature=youtu.be . The link for the "Heathkit-like" full construction article is also included.

Re: CC Skywave for Christmas

Here, just outside of Philadelphia, it's a large problem as the first adjacents to any of the local running it are useless. I'm between 3 and 12 miles from the locals. On FM it is far worse as there are more stations running it, and again, all of the first adjacents are blocked. Between the locals themselves plus the adjacents on FM, they comprise nearly half of the available frequencies

I believe you.
Perhaps, IBOC Hash isn’t a problem until you get some distance from the source.

I don’t know enough about IBOC to know if that is so.
I live in Mid-Michigan, just a few miles west of Lansing, MI.
The IBOC from Chicago’s WSCR “The Score, 6-70”, certainly hampers DXing for our area.

I’m a little curious.
What do you hear on 660 kHz and 680 kHz?

I belong to The Michigan Area Radio Enthusiasts Radio Club.
I just checked our 2015 Medium Wave logs summary.

The only station our members reported hearing on 670 kHz was WSCR.
On every other frequency that has a Chicago Station, at least two other stations were logged for the frequency.

IMHO, something appears to be out of Whack with WSCR’s IBOC.

Lightweight Hard-wired FSL Tecsun PL-380 Models

Gary DeBock
 

In answer to several requests, a lightweight version of the 3" Bar FSL Tecsun PL-380 has been designed, using 5 of the Russian surplus 100mm x 20mm x 3mm ferrite bars. This model is significantly lighter, more portable and less fanatical-looking than the original "Science Fiction PL-380," but doesn't give up much in the way of MW-DXing sensitivity.
 
 
 
 .
A related model using the commonly-available 62mm x 12mm x 4mm ferrite bars has also been designed, This is the lightweight version of the 4.25 inch "Pest Control" PL-380 version, which used 22 of the smaller ferrite bars. This lightweight version uses only 15 of the bars.
 
 
 
 
In what will probably be the last of these "Heathkit-like" full construction articles, the assembly details for both of these lightweight FSL antenna PL-380 models will be contained in an upcoming article. By reference to the FSL sensitivity design formula (coil diameter x ferrite length), the original 3" Bar FSL has a sensitivity rating of 300. The 4.25 Inch "Pest Control" model has a rating of 264, the new 2" Bar FSL model has a rating of 200, while the 3" FSL with the 62mm bars has a rating of 186. All of these models significantly exceed the 7.5" loopsticks in MW-DXing sensitivity, while the original 3" Bar FSL seems to have performance in an entirely different league.

Re: 3" Bar FSL on a Tecsun PL310

Gary DeBock
 

Hello Gregory,
 
Thanks for your comments on the 3" Bar FSL PL-380 article.
 
<<<   Any thought on what my Litz wire substitution might affect?   >>>
 
It's understandable that DXers would like to use the material that they have on hand to build a project like this, but unfortunately in many cases this results in MW sensitivity lower than what the original model provides.
 
In the case of Litz wire, the 250/46 size was chosen as the providing the best possible tradeoff between DXing sensitivity and ease of soldering to the crowded PL-380 circuit board. Larger Litz wire sizes (330/46, 660/46 etc.) provide more DXing sensitivity, but are increasingly difficult to solder to the circuit board without a serious risk of short circuits, or breaking off the antenna connection points from the circuit board foil. On the other hand, using Litz wire smaller than the recommended 250/46 size will result in lower MW sensitivity than in the article model.
 
In general, substitutions should be avoided if top DXing performance is desired. None of these parts are very expensive, and with the exception of the 100mm ferrite bars DXers in the USA should be able to track them all down. DXers in foreign countries have a tougher challenge.

Guys,

I had most of the parts on hand from earlier experiments so today I put together a 3" Bar FSL and hooked it to my Tecsun PL310.   I had to sub in 100/44 Litz wire - all I had on hand.  So far I've not done too much listening - I'll have time later tonight to do some listening and will report back. 

Special thanks to Gary for the excellent article on the FSL.

Any thought on what my Litz wire substitution might affect?

GPSFOOL.
