Gary:

It appears that you've  found a winner.  Maybe you won't have to lug the heavy weight FSL antennas to the Oregon coast in the future.

Good DX.

Richard.


New ULR station logged 3/26/16

bbwrwy
 

I logged a new station this morning, 3/26/16.

WNDZ, 750 kHz, Portage! Indiana (15 kW @ 1058 km/658 mi) was heard at 1159-1206 UTC. Station signed on at 1159 with woman saying "Good morning, this is WNDZ, Portage, Indiana", followed by a man speaking Spanish at 1200. The signal faded away at 1206. ULR station #1056 (barefoot #1043). Receiver: Sony SRF-T615.

Sadly, because of personal health issues, WNDZ is the first new station heard here since last April. I returned to using my tiny, mighty-mite SRF-T615 receiver this week. It's the one I'd logged most of my ULR stations on, including my first six Japanese stations. Recently, I've experimented using it with an 8-inch FSL with success. It's absolutely the best ultralight receiver, especially for domestic DXing.

Good DX everyone.

Gary, this one looks reproducible with scavanged MW radio ferrite bars.
I would  just take pot-luck with the foam :-)

Could you please  post an end-on jpg or sketch showing the dimensions,
ie concentric radius dimension of each layer.

Thanks!

Michael

After completion of the related construction article (about a week off), I do plan to send another package to Winnipeg with all the parts that you still need to make the model.

Sounds like virtually the same signal on both the 3” and 2” FSL’s. So for 3 less 100 mm bars (i.e. 8 versus 5 Ferrite Bars) resulting in a lighter weight, the same signal is heard - hard to argue with that!! Gary are there any upper bandwidth issues with the new 2” FSL?

Gary, wow, thanks a lot for your generous package offer to Winnipeg for the 2” FSL construction. I would be thrilled to have a go at this new FSL, - one item I have been trying to locate is hunting down the proper diameter of that blue spaghetti (heat shrink) wire from the inside of the Tecsun PL-380 to the Coil. If you have a piece to spare that would be great. Also I can reimburse you for any additional parts I will need, and for postage here to Winnipeg, Manitoba, Canada. Please let me know.

3" and 2" FSL Tecsun PL-380 Models-- 1575-VOA Reception A/B Comparison

Gary DeBock
 

For those interested, the exact same 33 second long signal of 1575-VOA was recorded on both a 3" FSL Tecsun PL-380 model and a 2" FSL model yesterday morning during the Thailand station's powerful fade in at 1341 UTC. The two models were separated by about 25 feet so that there would be no interaction, and both of them were set up 4 feet high above the ground.
This signal was recorded on the original 3" FSL Tecsun PL-380 model (with 8 of the Russian surplus 100mm ferrite bars)
 
This signal was recorded on the new 2" FSL Tecsun PL-380 model (with 5 of the same bars)

2" FSL Tecsun PL-380 TP-DX for 3-25 (Conclusion)

Gary DeBock
 

As reported previously, Asian propagation cooperated very well for the first TP-DXing test of a new 2 inch "Baby FSL" Tecsun PL-380 model (having 5 of the Russian surplus 100mm ferrite bars, instead of 8 as in the 3" model). From 1335-1355 there was a monstrous run from 1575-VOA in Thailand, managing its best signal here over the past couple of years. The new 2" FSL PL-380 model recorded various S9+ peaks from the long range DX station, resulting in one of the most interesting sessions this year.
 
At my 1255 start time the usual NHK big guns on 594, 693 and 747 were in and out with good signals, along with 1566-HLAZ. Early on 738 had a strong carrier which stuck around for most of the session, although until increasing daylight it was lost in the KCBS splatter. By 1325 the San Francisco pest started to bite the dust, though, and 738-BEL2 (with the usual female news announcer) rose to weak Chinese audio in and out for much of the rest of the session. This was the 16th TP station received on these stand-alone FSL-enhanced PL-380 models. Besides this and an unusually strong signal from the 1053-Jammer around 1330 it seemed like it would be another Japanese big gun-dominated session, until 1575-VOA came out of nowhere to rise up to a blisteringly strong signal by 1338. The tiny 2" FSL PL-380 model looked pretty ridiculous pulling in the 7,329 mile DX station at a local-like level, but that's exactly what happened at 1339 (another bizarre photo of this is posted at https://app.box.com/s/w0zkef8vxhiuk25alko7ay70pygxxu6l  )
Although the rest of the high band was distinctly anemic 1575-VOA stuck around at a potent level from 1335-1355 while the NHK big guns on 594, 693, 747 and 828 faded in and out (along with an anemic 603-HLSA) until a general collapse around 1400. Overall the session was pretty astonishing, with 1575-VOA's overpowering signal the best that it has managed here since 2013.       
1053  Korean Jammer   Fairly strong jam session at 1331; best jam signal yet on these hot-rodded PL-380 models
 
1575  VOA   Ban Phachi, Thailand   Another S9+ recording with female speech and interval music at 1338; the station stayed
             steady at this blistering level for a full 10 minutes

<<<   Wow, this is fascinating indeed!

There must be a research-niche to compare overall FSL diameter, number of ferrite bars, dimensions of the same,
litz-windings etc so as to evince the overall best compromise FSLs for stock-limited  ferrite hoarders.

I impatiently  look forward to further reports!   >>>
 
Thanks, Michael. I plan to write a full report on this Baby FSL experimentation after more detailed testing and TP-DXing. The ultimate goal is to come up with a (commonly available) 62mm ferrite bar FSL version which will be a worthy representative of the "science fiction" genre. Too bad we didn't have these little DXing monsters as teenagers-- who knows what we could have accomplished as ocean beach radio fanatics? :-)

Wow Gary….if you keep making these FSL's smaller and smaller and keep getting the same good results,
pretty soon you'll be back to the Original Ferrite Loopstick that was in the radio when you got it in the first place!! HAHHAHAHA…….

You may eventually invent the "Micro FSL" that will fit into the Radio's Case instead of being stuck to the top of the case…….

You're definitely breaking new ground here…….

Thanks, Rob! As you might guess, I'm having a total blast here... these Baby FSL's pack a very mean DXing punch!
 
Too bad I didn't have these little monsters available when I asked for Canadian volunteers to test out the SRF-59's back in January of 2008-- you probably would have tracked down 300 TA's in 30 days!! :-)

Thanks Guido but that's not it. The map you sent though is great! -jake


Re: Map created by a member

Rik
 

This might be really handy for me since I am setting up a spread of BOG antennas and seeing on a map the direction for each log would help judge the real patterns they have. Topaz Designs shows distance and  bearings to and from an AM BCB station I log, so I have been adding the bearing to more recent logs, but seeing it on a map would be better still.  -FARMERIK
