Date   

3" FLTecsun PL-380 TP-DX for 3-31

Gary DeBock
 

While I was still in Puyallup it was a great morning for the NHK big guns and 1566-HLAZ but certainly lacking the variety of Asians showing up yesterday. Except for the usual regular 603-HLSA my results were almost identical to those reported by Bruce. A very late rally by the CRI stations on 1044, 1206 and 1323 around 1345 provided a little variety but the band folded before they could come close to yesterday's levels.
 
At my 1250 start time both 594 and 1566 had very good signals, and these were joined by 693, 747 and 774 during the predawn darkness. First daylight around 1320 didn't change propagation much, except for 603-HLSA and 972-HLCA coming out of the noise to reach fair levels in and out. By the 1330 start of the NHK2 Chinese lessons the signal from 747-JOIB was the strongest that it's ever been on these hot-rodded portables, and 594 and 693 weren't far behind.  603-HLSA reached a slightly stronger level than yesterday (fair) around 1340, and 1575-VOA was also slightly improved, keeping steady fair audio during sunrise enhancement. The late mid-band CRI rally might have gone somewhere except for the band's general collapse at 1350, another example of Puyallup's lackluster propagation in comparison to ocean beach areas. That won't be a problem for the next 4 days, as a collection of hot-rodded PL-380's, FSL antennas and digital recorders is eager to hit the salt water beach next to the Walsh Motel in Grayland ($180 for 4 days, as long as you don't set up large external antennas or put ground stakes through water lines).      
747  JOIB   Sapporo, Japan   Very good level Chinese lesson start at 1330; strongest signal ever on these models
 
73 and Good DX,

Glad to be of assistance.
The firefighter driving the rig suffered a medical emergency and struck several vehicles while others in the truck eventually stopped the truck. He was the only injury and is expected to make a full recovery.

Thanks to a great tip from Kevin Asato
I searched for for station KSL / Salt Lake City, Utah / 1160
kHz and was able to capture it at 5:40 AM  yesterday
morning with a fantastic local station signal level of 63 /
25 on the Tecsun PL-380 with attached 3"
FSL from here in
Winnipeg - distance is 953 air miles.
 The announcer said conditions in Utah country were cloudy
with a temperature of 37 degrees. KSL started fading out at
6:45 AM. 
At 6:30 AM Los Angeles Station
KFI  / 640 kHz / 1532 air miles distance was again picked
up for the 2nd time in 3 days with a strong clear signal
level of 47 / 25 - Coast To Coast show was on. The news
broadcast mentioned something about a fire truck crash in
North Hollywood or Van Nyes. Temperature in Burbank was 48
degrees and they were requesting listeners to sign a
petition at: KFIAM640.com to prevent the FCC from cutting
back their sunrise conditions Transmit power. KFI completely
faded out at 7:05 AM CST Winnipeg time. Hope they are
successful with the petition so that us DXers can still
pickup KFI which is an amazing catch.

New ULR station 3/31/16

bbwrwy
 

I logged a new station this morning, 3/31/16.

KLBJ-AM, 690 kHz, Austin TX (5 kW @ 683 km/425 mi) was heard from 1259 to 1306 UTC, identifying as "Newsradio KLBJ". Faded under KXSP, Omaha NE, at 1304. Receiver: Tecsun PL-606. ULR station #1057 (barefoot #1044).

I'm surprised I hadn't heard KLBJ-AM before.

Good DX everyone.

Only one Asian station was heard on 3/31/16 (LSR @ 1217 GMT) using a PL-606 receiver and 8-inch FSL.

1144-1152 JOUB 774 poor to fair strength at 1144 with moderate lightning static, improving to fair at 1146, peaking at good strength at 1150. Signal was audible on barefoot PL-606 at 1150.

1200-1202 JOUB poor with man and woman talking. Moderate static and slight QRM from local daytimer KSPI 780 (s/on 1200).

3" FSL Tecsun PL-380 TP-DX for 3-30

Gary DeBock
 

Thanks to Richard for his TP-DX report from Oklahoma. It was a pretty good morning here for Chinese stations, with both 738-BEL2 and 1044-CRI managing audio on the "Science Fiction PL-380" model during a generous sunrise enhancement. Other Chinese stations on 936, 1035 and 1323 reached threshold levels at times, but couldn't quite stick around for more than a few seconds each.
 
My session started at 1300 with the usual big guns on 594, 693, 747, 774, 972 and 1566 already in and out with fair audio, along with 603-HLSA and 1575-VOA at similar levels. There were some promising Chinese carriers on 936 and 1035 at my 1300 start time, with both stations managing threshold audio for brief periods between 1300 and 1330 (but not strong enough for positive language identification). At 1335 the Japanese service from 1044-CRI broke into clear audio with male and female speech, easily the best peak it has ever had on these hot-rodded portables. Shortly thereafter 738-BEL2 (with the usual hyped-up male announcer) faded in with its first pop music peak at 1337, to be followed by a slightly stronger peak at 1347 shortly before the band folded here. The 1035-CNR1 synchros had a pretty strong carrier for most of sunrise enhancement but only managed ghostly echoes on peaks, while 936 seemed stuck in the twilight zone between readability and noise. During sunrise enhancement almost all of the NHK big guns were potent indeed but most of the attention here was on the unusual Chinese stations. Both 738-BEL2 and 1044-CRI had pretty decent signals at times, considering the 3" x 4" antenna of the stand-alone FSL PL-380 model. As such, the session was another total blast (despite the weaker Chinese stations that couldn't quite seal the deal).
 
738  BEL2   Penghu, Taiwan   Chinese pop music with fair peaks hosted by the usual hyped-up male announcer at 1347
 
1044  CRI   Jiangsu, China   Male and female Japanese speech and Chinese music during Japanese service at 1336

I was able to hear JOUB 774 between 1148 and 1201 GMT using my Skywave receiver with the 8-inch FSL. The signal strength was poor at best. No other TP signals were observed.

Re: Amazing Los Angeles - Winnipeg AM DXing Station Capture with 3" FSL

jerry popiel
 

Thanks for the detailed listening info Kevin. I will check out those frequencies, the only one that won’t work is KNBR at 680 kHz as we have CJOB at 50,000 watts here in Winnipeg. I did capture KFI - at 640 kHz again this morning @ 6:40 AM for about 5 or 6 minutes but it was much too noisy and erratic (nothing close to as clear as yesterday) for any meaningful listening all I caught was a station ID in between commercial info on what sounded like the George Norrie Show. Thanks for your help.

Peter Rankin
 

I am in Oshawa Ontario and often hear Winnipeg,Minnesota and out that way also to the east Montréal Ottawa .The FSL has helped a lot.I sometimes hear Georgia and Florida to the south.I will try to log some reports .I use the Sony SRF-T615,SRF18 for the super dxing,but often use old vintage stuff with RF amps or tuned RF stage.Thanx for letting me chime in Gary... this is a great place for all us MW addicts.... and we know who we are hahaha 73

Hello Zort 7,
 
<<<   I built a hackneyed FSL to help out my MW dxing.I used 8 6.5" ferrites scavenged from the parts pile.They are tywrapped around a hunk of 1/2" pvc insulated by a toilet paper tube and then about 35 turns of used Litz tied to an old cap with verneer drive a band a big old knob.Tunes handily ffrom 500-1750.It works great about 3" from the set.I will try and post a pic soon.No science to this homejig but it works amazing!Thx for spurring the iidea friends   >>>
 
Congratulations on your successful completion of the homebrew FSL antenna.
 
Steve R. and I were two of the original FSL experimenters (after Graham Maynard's introductory article in February of 2011), and we always have interest in new variations of this small but effective antenna. Good luck!

Re: Amazing Los Angeles - Winnipeg AM DXing Station Capture with 3" FSL

kevin asato <kc6pob@...>
 

Some information on what you heard -

AM Radio Station KFI broadcasts at 640KHz with 50KW power day and night in the Los Angeles Market Area..

What else to listen for -
Another clear channel 50KW day/night broadcaster is KNX at 1070KHz (in my backyard). Just below KFI is KTAR in Phoenix, 620KHz, which publishes it's power output at 5KW. You can possibly hear this if tuning just below KFI. i have managed to pick KTAR out of the background noise of KFI on a crystal set here in Los Angeles County. Going up to the north There are KNBR in San Francisco (Belmont) at 680KHz and KSL (1160KHz) in Salt Lake City that are also granted clear channel privleges of 50KW output power.

Happy Hunting!.

Thanks for the replies and info Jay and Gary. Gary,
I still can’t believe yesterday’s LA Stn capture in the
South / West direction as well, I will be looking at 640 kHz
more often from now on!


Re: 2" FSL Tecsun PL-380 TP-DX for 3-25 (Preliminary)

Hello Michael,

I have built two FSLs using packing foam that I purchased at my local U-Haul trailer rental store. Seems to work great for me. My latest 12 inch wide by 7.5 inch diameter really kicks a$$. I have compared it to the CCrane twin coil active antenna and the FSL EASILY outperforms it. Good luck on your project.

Thanks, Gary, that should be enough to play
with. I got a
dozen old AM radios from a

defunct  hotel. Their ferrites  and  litz should
do. I have foam
that looks ok - but of course

it might be impregnated with lead - or worse.  I am
sure I'll
find something that works!

(Anybody tried materials other than Oatey for an
FSL?)



Must get one built so I can hear The Incumbant's
victory speech
if the digital networks all go down...

Michael, I've attached a design photo
with a close-up
of the 2 inch FSL
antenna construction.
 
There is no Funnoodle used in this
model-- there is
simply a 4" length of 1/2" outer
diameter PVC pipe with
a couple of wraps of Oatey foam used as the
padded base
for the 5 Russian surplus 100mm x 20mm x 3mm
ferrite
bars. These bars are no longer sold on eBay,
so they are
in great demand currently. I don't mind
shipping an
Oatey foam pack to the U.K. (for the cost of
postage),
but as with most of the DXers who are
interested in this
model you will need to track down suitable
ferrite bars.
Hopefully another eBay source for these
100mm bars will
open up in eastern Europe (without knowledge
of how much
they are in demand, of course).

3" FSL Tecsun PL-380 TP-DX for 3-29

Gary DeBock
 

Unlike yesterday both the low and high band Asians received a major propagation boost during sunrise enhancement, with 558-HLQH finally strong enough to get through the KPQ splatter on the hot-rodded PL-380 at 1342. 531-JOQG also built up enough strength to confirm the 594 parallel around the same time, while 1503-JOUK was the star of the high band with a vibrant run during sunrise enhancement.
 
At my 1300 start time the band sounded pretty subdued, with only the Japanese big guns on 594 and 693 and 1566-HLAZ managing fair strength in and out. Asian signals stayed at a modest level until around 1320, when 747-JOIB suddenly came out of the noise to a very good level with its English lessons. The other NHK regulars on 594, 693 and 774 got the same boost, while the KBS2 parallels on 558 and 603 both reached steady audio around 1328 with speech by the deep-voiced male (with 558 fighting the KPQ splatter). The strength of 558-HLQH reached an exceptional level around 1330, which was fortunate because most of the time the only way it could be recorded (through the KPQ splatter) was to record it on 557 kHz. By 1340 almost all the low band Japanese were on potent runs, and I decided to check a long-term target on these hot-rodded portables, 531-JOQG. Sure enough it was there at a weak level with Japanese male and female talk // 594, the 19th TP station to be received on these FSL-enhanced PL-380's (after 558-HLQH was #18). The high band also had one standout performer around 1345, with 1503-JOUK going on an energetic run similar to the low-band Japanese around 1345. Besides these there were fair signals in and out from 972-HLCA and the 1053-Jammer throughout the session, and threshold audio from the CRI stations on 1044 and 1323 (but never strong enough for positive language identification). On the other hand the strength of both 531-JOQG and 558-HLQH was the best that either station had managed during the entire season here, with 558's strength at 1330 similar to those of the bi gun Japanese signals on 594 and 747.

Thanks, Gary, that should be enough to play with. I got a dozen old AM radios from a
defunct  hotel. Their ferrites  and  litz should do. I have foam that looks ok - but of course
it might be impregnated with lead - or worse.  I am sure I'll find something that works!
(Anybody tried materials other than Oatey for an FSL?)

Must get one built so I can hear The Incumbant's victory speech if the digital networks all go down...

Michael, I've attached a design photo with a close-up of the 2 inch FSL antenna construction.
 
There is no Funnoodle used in this model-- there is simply a 4" length of 1/2" outer diameter PVC pipe with a couple of wraps of Oatey foam used as the padded base for the 5 Russian surplus 100mm x 20mm x 3mm ferrite bars. These bars are no longer sold on eBay, so they are in great demand currently. I don't mind shipping an Oatey foam pack to the U.K. (for the cost of postage), but as with most of the DXers who are interested in this model you will need to track down suitable ferrite bars. Hopefully another eBay source for these 100mm bars will open up in eastern Europe (without knowledge of how much they are in demand, of course).

I built a hackneyed FSL to help out my MW dxing.I used 8 6.5" ferrites scavenged from the parts pile.They are tywrapped around a hunk of 1/2" pvc insulated by a toilet paper tube and then about 35 turns of used Litz tied to an old cap with verneer drive a band a big old knob.Tunes handily ffrom 500-1750.It works great about 3" from the set.I will try and post a pic soon.No science to this homejig but it works amazing!Thx for spurring the iidea friends

Thanks for the replies and info Jay and Gary. Gary, I still can’t believe yesterday’s LA Stn capture in the South / West direction as well, I will be looking at 640 kHz more often from now on!

Here at WTIC we don't have formal QSL cards but our enginers do answer QSL's personally.

Hi Jerry,
 
<<<     Gary, nice compact Antenna. Is that the 250/46 Litz Wire and how many turns for the 5 - 100 mm Bar unit? Does it have the 1/2"PVC inside the Funnoodle?   >>>
 
This new 2" FSL model has no Funnoodle, but simply uses a couple of Oatey foam turns around the 1/2" outer diameter PVC pipe. I've attached a design photo with this email.
 
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. Based on your successful completion of the 3" FSL Tecsun PL-380 model, I think that it will be  breeze for you-- and this tiny model is a real DXing thriller.
