This problem is specific to the PL880. I cant speak for any other models. There are pictures and/or posts that Gary posted when he dissected both versions of the radio to try to get to the bottom of the noise that was being noticed on newer models. It appered that Tecsun ran out of or changed to a different part in newer models that was not compatible with the original shield so they just simply stopped installing the shield. Trouble is, that part was clearly an oscillator or resonator can that really should be shielded. Without the shield, noise radiates through the lcd window and is able to get picked up in the rf front end. This can be proven or expierimented with by simply placing a thumb over the window while tuning around the lf band and parts of the am band. As you might expect, the problem is more noticable in quieter locations but many times is far above the local noise floor even in noisey locations. So what can you do about this if it bothers you? Well if you are really good you could perform surgury and fashion some sort of shield. You will need to be really good though because just getting to the area requires a complete disassembly of the radio and the area to shield is small with many chances to short out traces etc. Mere mortals may want to get their hands on an older model. Somewhere there is a post that explains the location of some identifying text on the box flap otherwise there is no other way to tell. Since I'm in a unique situation of having both models supercharged and I have access to some really nice equipment, I figured I'd do a quick measurement to confirm what has been heard. Do not take the data out of context though. The plots are just relative plots in the amplitude domain. I had to put each radio within inches of an antenna that is calibrated for 1 meter to get any results at all. If you are having problems with an active antenna overloading the front end of another model, the data on that plot will not help you at all. You are going to have to keep fishing for answers one of which may be switching to a real tabletop radio with a real 50 ohm antenna input.

No my issue isn't with noise from local sources... I used a pa0rdt active antenna this weekend.... The radio worked fine without it, but I wanted the added amplification. I used it on my 909 and it did the same thing. I have to do a bit more troubleshooting. It shouldn't overdrive the
radio. The 380 works fine with the external ferrite sleeve antenna. I put the jack back in so I could use external antennas for LW and SW But the pic is the first I've heard of internal radio noise issues. Anyone have info on this shield or mods?... With my cover off there are no shields on the back... There are some in between the boards and on the front I think. Best Regards Phil WA2069SWL Lat: 40.8367633 Long: -74.1768412 From: "n3ikq@...

Sent: Monday, July 28, 2014 2:22 PM Subject: Re: [ultralightdx] New file uploaded to ultralightdx The picture shows nothing more then the noise being generated within the radio. The measurement was taken in a shield room that is free from all outside rf signals. It has nothing to do with how the radio responds to wanted radio signals. Even with the noise issue, the supercharged PL-380 (old or new) is a wondrous thing. You just have some noise pop up at certain frequencies as you tune the dial. If YOUR radio is overwhelmed by external noise the first thing you need to do is move to a park or other quiet location to make sure the problem is not coming from a local source of which there are thousands and go from there.

I hope this is not going to turn into a systemic penny pinching move across their entire line... I have always thought Tecsun cut corners mostly where it didn't matter, but this is something that will put them on the fast track to making pure junk! I'm down a radio and was thinking of getting another Tecsun PL-380... now I don't which one to buy.... I wonder if they have messed up the PL-310ET too?? Mark B. N8PGV

Hello,
How can volume/tune knobs being used when faulty. Are there ways to connect the pins of the volume/tune knob, so that they can be tuned? I have added pictures under Files---->6 Alignment & Modification---->pl380-pl390 volume tune knobs Anybody any ideas? A simple try to connect some of these pins, and give some voltage to the volume knob didn't work ... Marc -- The "Penguin" has arrived - and he's not going away - ever.

Hello,
This email message is a notification to let you know that a file has been uploaded to the Files area of the ultralightdx group. File : /Tecsun PL-380.jpg Uploaded by : n3ikq <n3ikq@...> Description : Difference between the old and new version of the Pl-380. The new version PL-380 had some component changes and does not have a crucial shield installed as evidenced by the 20dB higher noise. This is just visual confirmation that the newer units suffer from some very annoying noise that degrades their LF and low BCB band performance even when (or especially when) supercharged.

July 13-19 Rockwork 4 Ocean Cliff DXpedition Loggings and MP3's
Hello All,
From July 13-19 another major ocean cliff DXpedition was conducted at the "Rockwork 4" site, located about 15 miles south of Cannon Beach, Oregon on a narrow Highway 101 turnoff. During the one-week search for South Pacific DX a 7.5" loopstick Tecsun PL-380 Ultralight radio was given inductive coupling boosts by a new 15" FSL antenna, which was set up right on the edge of a 400 foot (122m) straight-down plunge to the Pacific. On two of the days (July 16 and 17) I had the privilege of welcoming noted DXpeditioner Chuck Hutton to the narrow site, and he in turn enjoyed two days of exceptional New Zealand DXing results with his Perseus-SDR and 15' by 15' Flag antenna.
Listed below are my own South Pacific DXing results with the 7.5" loopstick PL-380 and 15" FSL antenna combo, which (like Chuck) received potent transoceanic DX signal boosts from the sheer ocean cliff. MP3 recording links for most of the receptions are listed with the loggings, and signals which pegged the PL-380's S/N display at the 25 maximum at least once during the recording are identified with a double asterisk (**). For those interested, a July 2014 Rockwork 4 DXpedition video has been posted at http://www.youtube.com/watch?v=lNSSJIVV6Zg , and an "Apples and Oranges" DXpedition video showing Chuck's listening setup and mine is posted at http://www.youtube.com/watch?v=tAZaY8b4Eec . Finally, a demonstration video of the reception of the 5 kW Kiwi station 531-PI on the modified PL-380 at the ocean cliff site just after sunrise on July 19th has been posted at http://www.youtube.com/watch?v=ITBJ31cEAH0 Chuck also had superb Perseus-SDR DXing results at the cliff, and we have a plan to combine our loggings for a final DXpedition report at a future date.
**531 PI Auckland, New Zealand (5 kW) The strength of this Samoan-language NZ station over the 7 day trip was
exceptional-- it pegged the PL-380 S/N every morning, and always kept the Australian co-channels way down.
This particular signal at 1230 on 7-19 was the strongest DU signal that I've ever heard in any DXpedition.
531 UnID Australian In general the Australian stations on this frequency had a very rough time breaking through the
heavy 531-PI signal, but in this recording at 1233z on 7-17 there is an Australian pop music station mixing with
PI at a fair level, with a female presenter giving some speech from :08 until :17 into the recording. Not too much to
go with, but possibly 2PM in Kempsey, which was heard last July at this site (headphones recommended)
531 UnID Australian Another Aussie signal under PI's overwhelming speech at 1258 on 7-16. Apparent male talk format,
but this may simply be news just prior to the TOH. Don't know if this is the same Aussie as above, or not
558 Radio Fiji One Suva, Fiji (10 kW) A big surprise at 1233 on 7-18, this station was received for the first time in 4
years. As the last surviving Fiji MW outlet there is no parallel to check, but it's the only DU on this frequency with
a Polynesian mx format. Received at a fair level when South Pacific propagation was no so Kiwi-slanted
**567 RNZ Wellington, New Zealand (50 kW) This Kiwi big gun usually hit an exceptional strength level every morning,
although it occasionally had issues with 570-Seattle splatter. With music, news and interviews, it was a
convenient signal to confirm reception of other RNZ stations across the band. It almost always pegged the PL-380
S/N at least once a morning, and was the strongest RNZ outlet in the network
576 The Word Hamilton, New Zealand (2.5 kW) Obscure, low-powered Kiwi station was a big surprise on 7-16 at 1246,
with Bible reading at a fairly good level because of a completely absent 2RN. This was an apparent all-time new
west coast DU logging by Chuck and I during this DXpedition, with Chuck also mentioning reception of the 1.5 kW
transmitter on 540
576 2RN Sydney, Australia (50 kW) MIA during much of the DXpedition, this RN network big gun finally reclaimed its
usual spot over the low-powered Kiwi at 1241 on 7-18. Since The World broadcasts Bible reading 24 hours
a day, the Australian big gun was always easy to distinguish
585 Radio Ngati Porou Ruatoria, New Zealand (2 kW) This underperforming Maori-language station is one of the
toughest Kiwis to track down, and it only appears during exceptional propagation. The only way to identify it is to
check its programming against late-night parallels on either 603 or 765, and it's rarely strong enough to do this.
Fortunately this was barely possible at 1236 on 7-15 (17 seconds each of 585 and the 603 // on the MP3)
585 UnID Australian This fairly weak signal was definitely not // 603, so it wasn't the weak Kiwi. Both male and
female presenters are audible, although it's tough to dig out any detail. "Outback Radio" 585-2WEB has
been heard here three times during previous DXpeditions, but ABC station 7RN in Hobart is also a possibility
**594 NZ's Rhema Timaru/ Wanagnui, New Zealand (5 kW/ 2 kW) This relatively low-powered Christian music
broadcasting network blasted into the Cliff with this monster signal on 7-19-- the strongest that I've ever heard
it. Holding strong on the frequency all week, it never allowed to Aussie big gun 3WV to manage a trace
594 JOAK Tokyo, Japan (300 kW) NHK1 big gun crashed the DU-DXing party for about 5 minutes around 1213 on
7-14 before quickly being evicted by NZ's Rhema. This was the first appearance of a Japanese station in July
at the Rockwork 4 cliff; no Asian had ever shown up there for 2 full July DXpeditions
**603 Radio Waatea Auckland, New Zealand (5 kW) Maori language broadcaster plays a variety of Maori and
American R & B music, and is parallel with fellow Maori broadcasters on 585 and 765 in NZ's early morning.
This huge signal (with a Maori ID) showed up on the last day at the Cliff
**657 Southern Star Wellington/ Tauranga, New Zealand (50 kW/ 10 kW) This Christian hymn broadcaster was a real
Kiwi big gun on most mornings, although it typically had some domestic splatter issues. This potent signal was
recorded during exceptional Kiwi propagation on 7-16
675 RNZ Christchurch, New Zealand (10 kW) The second strongest RNZ outlet (after 567), it features music, news and
interviews. Parallel to 567, 639, 756, 837 and other RNZ network frequencies
684 NZ's Rhema Gisborne, New Zealand (5 kW) Usually slightly weaker than its parallel on 594, this station could also
be quite potent at times with its Christian contemporary music and sermons. Here it is at 1244 on 7-14
**702 Radio Live Auckland, New Zealand (10 kW) The potent signal of this obscure Kiwi station was one of the biggest
surprises of the entire DXpedition. Usually buried by (or mixing with) Aussie big gun 2BL, it rode the freakish Kiwi
propagation to this exceptional S9 level on 7-13, pegging the PL-380 S/N readout for almost 3 minutes
702 2BL Sydney, Australia (50 kW) In contrast to the potent Kiwi Radio Live, this RN network big gun usually sounded
pretty Dead. It didn't show up at all until the last day of the DXpedition, with a fair signal seemingly // 774
**738 Radio Polynesie Mahina, Tahiti (20 kW) This French-language blowtorch had no trouble pounding in each
morning, completely shutting out both Aussie big gun 2NR and the obscure 5 kW Kiwi, Radio Live. When it really
blasted in (like with this pop music on 7-18), it could turn the tables, and throw splatter on the SF pest 740-KCBS
756 RNZ Auckland, New Zealand (10 kW) Not one of the stronger RNZ outlets during this DXpedition, as is fairly
typical of its usual performance. Proximity to the major 750-Portland pest doesn't help matters
**765 Radio Kahungunu Napier-Hastings, New Zealand (2.5 kW) The potent signals from this low-powered Maori
broadcaster were nothing short of amazing. Parallel to other Maori stations on 585 and 603 during the early
morning in NZ, it was almost always the strongest one of the three. It blasted in with this signal at 1217 on 7-14
774 3LO Melbourne, Australia (50 kW) Another Aussie big gun completely shut out until the last day of the DXpedition.
Showing up at a fair level through 770-Seattle splatter, it provided an LR network parallel for a couple of other
Australian stations on 7-19, right before the trip wrapped up
783 Access Radio Wellington, New Zealand (10 kW) Fairly good signals from this multi-ethnic Kiwi station all week
long as it enjoyed a complete lack of Australian competition. This temporarily strong music was received on
7-16, one of the most favorable days for NZ propagation
792 Radio Sport Hamilton, New Zealand (5 kW) Dominant on the frequency almost all week, this fairly obscure
Kiwi station shut out the Aussie big gun 4RN until the last day. This fair-level conversation about the WNBA
on 7-15 was typical programming
792 4RN Brisbane, Australia (25 kW) Aussie big gun was MIA until the very last day (7-19), finally showing up with
this fair-level female speech // 576 at 1302
828 Live Sport Palmerston No., New Zealand (2 kW) In this MP3 recorded across the 1300 TOH on 7-15 the station is
apparently relaying TAB TV, as per the PAL listing. Not thought to be the ABC station 3GI because of the
commercial ads ("brought to you by...") after the TOH pause
828 Radio Trackside Palmerston No., New Zealand (2 kW) Same transmitter as above, but broadcasting horse racing
at an anemic level on 7-13 at 1156 (prior to the 1200 TOH when Trackside programming wraps up)
828 UnID-DU This is almost certainly the Australian 10 kW LR network station 3GI in Sale showing up with
fair-level female speech on the last day (like many other Australians), but I wasn't able to confirm the 774 //
837 RNZ Whangarei/ Kaitaia, New Zealand (2.5/ 2 kW) The weakest of the RNZ relays picked up during this trip,
but not surprising when only 3 kHz next to the semi-local 840-KSWB in Seaside. Heard // 567 at 1233 on 7-17
855 NZ's Rhema Hamilton, New Zealand (2 kW) This station was received at an anemic level twice during the
DXpedition // 594, but I was waiting for a better signal to record an MP3. Of course, it never cooperated.
**891 5AN Adelaide, Australia (50 kW) Although many Australian big guns were MIA during the DXpedition, this
South Australian blaster certainly wasn't one of them. This blistering signal pounded into the Cliff at 1253 on 7-14,
as the LR network big gun apparently rode a different propagation path than the MIA eastern Australian stations
936 Chinese Voice Auckland, New Zealand (1 kW) Exceptional Kiwi propagation on 7-17 finally made it possible to
record Chinese from this flea-powered station. This apparently was a new Ultralight radio DXing distance record
for 1 kW station reception in North America, and the first 1 kW New Zealand station I've ever received
936 UnID Australian Weak non-Chinese music showing up on the last day (7-19), one of the few days with any
Australian propagation. No real identity clues, but probably one of the 10 kW Aussies on the frequency (4PB or
7ZR). The flea-power Kiwi station Chinese Voice held down the frequency (weakly) on the other six days
963 Southern Star Christchurch, New Zealand (10 kW) Usually not quite as strong as its 657 parallel, this Christian
hymn broadcaster could occasionally manage good signals. Unlike previous DXpeditions there was no
Australian competition all week long
1008 Newstalk ZB Tauranga, New Zealand (10 kW) This Kiwi news station had a decent signal on most days but
didn't benefit from a blasting domestic pest on 1010. For some unknown reason its 1035 // was MIA despite
several searches during good Kiwi propagation.
1017 A3Z Nuku'alofa, Tonga (10 kW) This somewhat obscure DU waited until the last day of the DXpedition before
showing up before a late sign off, but a Spanish pest on 1020 made reception a little dicey. The usual foreign-
language male speaker rose up out of the 1020 splatter at a fair level at 1154 on 7-19 (headphones
recommended), occasionally speaking "island-style" (bizarre pauses between sentences)
http://www.mediafire.com/listen/el5z3pufpapaf3n/1017-A3Z-1154z071914PL380.MP3 The station returned
with good-level interval music and the same male speaker at 1158 before the 1020 Spanish pest
reclaimed the frequency-- dashing hopes of a vibrant sign-off recording
1017 Radio Sport/ Newstalk ZB Christchurch, New Zealand (2.5 kW) This was the best signal that I've ever heard
from this low-powered Kiwi station, with good level male conversation and a female commercial ("right here in
New Zealand") on the last day of the DXpedition at 1241
**1116 4BC Brisbane, Australia (16/ 7.3 kW) This eastern Oz commercial big gun managed pretty potent signals but
had the misfortune of being only 4 kHz away from the 50 kW Oregon pest KPNW. Despite this it was one of the
few Aussies to provide decent signals each morning, and certainly worthy of a "Top Ten" spot of the strongest
DU signals throughout the DXpedition
1386 Radio Tarana Auckland, New Zealand (10 kW) Female-voiced Hindu music at a good level from this ethnic station
at 1311 on 7-19 (the last day of the DXpedition). This signal (and other high-band DU's) got a serious boost from
the new FSL's dual coil tuning system
1503 Radio Sport Wellington, New Zealand (5 kW) The strongest signals that I've ever received from this high band Kiwi
station at 1248 on 7-13, with a female-voiced "I want some sports..."

Re: Rockwork 4 DU-DXpedition-- South Pacific UnID's and Mysteries
Bill Whitacre
Hi Gary. Now that we’ve established 531 as the ‘benchmark’ of our DXpeditions this year I’ve been listening to it a bit. This morning, 7/23, at Sans Souci was pretty much an Aussie event. Good time to check 531 for something other than PI!
toggle quoted messageShow quoted text
Sure enough on my 1200utc TOH recording I’ve got an Aussie dominant with a program called ‘Help Line’ and a commercial for something with a ‘clubhouse’ near Frederickton with a phone # announced as 65-87-3020. Nothing came up on Google for that, unfortunately. Later in the 8 minute cut I’ve got a commercial for Litz’s [?] News Agency & Takewawy somewhere in NSW. PAL shows only one station in NSW on 531, in Dempsey. I’ll bet that’s what we’ve got. ---

Rockwork 4 DU-DXpedition-- South Pacific UnID's and Mysteries
Hello All,
As usual, the recent visit to the Oregon ocean cliff site resulted in a mix of definite and not-so-definite DU loggings. Most of the mysteries were related to Australian stations trying to break through the strong NZ-slanted propagation.
Posted below are several MP3's of these mysteries, along with descriptions of what I can make out by myself. The 702 kHz recording is pretty strong, so anyone in NZ or Oz could probably tell me the accent of the female presenter. Any assistance would be appreciated!
531 UnID Australian In general the Oz stations on this frequency had a very rough time breaking through the heavy 531-
PI signal, but in this recording at 1233z on 7-17 there is an Australian pop music station mixing with PI at a fair level,
with a female presenter giving some speech from :08 until :17 into the recording. Not too much to go with, but does
anyone in Oz recognize her voice? (headphones recommended)
531 UnID Australian Another Oz station trying to break through PI's hammerlock on the frequency. At 1258z on 7-16
a male-voiced presenter on an Australian station is speaking under 531-PI's Samoan male presenter. Being close
to the 1300 TOH, this may have been some type of news. Does anyone in Oz recognize his voice? (headphones
recommended)
585 UnID Australian At 1238 on 7-17 a fairly weak station was received on 585, but it was clearly not // with 603-Waatea
(i.e., it was not the 2 kW Kiwi station 585-Radio Ngati Porou). This leaves only two Oz stations as real possibilities--
585-2WEB "Outback Radio" (received three times previously on the Cliffs) or the 10 kW ABC station 7RN in Hobart,
Tasmania (never before received). Both male and female presenters are giving either an interview, or news. Any
suggestions from Oz? (headphones recommended)
702 UnID DU This fairly strong station at 1211 on 7-19 is obviously either the Kiwi 10 kw station Radio Live or the Aussie
50 kW big gun 2BL, but since an LR network // wasn't available at the time I couldn't confirm the ABC identity. My
guess is that this is 2BL because of the complete lack of commercial advertising from the female presenter, but
could someone in either NZ or Oz confirm her Aussie accent?
Thanks for any assistance!

Re: Rockwork 4 DXpedition-- Top Ten Signals from the South Pacific
Tony Ward
This was a wonderful trip to follow, and an inspiration! The hobby has moved on a fair bit from some of us sitting on NZ beaches, listening to the "Yanks hosing in", at sunset, as we explained it to our bemused friends. In my case this was with a National Panasonic "9 transistor radio", circa 1960 or so --- though MW DXing started a few years before with "mantle" receivers. KFI was pretty reliable listening from the beach, as were many others! The serious work was done from Lloyd Clayden's legendary Whangaparaoa antenna farm --- but that is another story altogether.
So the next step is to get KAZ and yourself to figure out how to phase these two marvellous cliffs, Perpetua and Rockwork4, to move the game up another notch or two! Well done!! --- Tony (VE3NO) Enhancing Universal Entropy since 1942...

Re: South Pacific DXing Demonstration Video-- 531-PI in Auckland, NZ
Hello Valjoy007,
Thanks for your comments!
<<< I might have missed this in the file archive but....How are you determining the optimum amount of turns of litz for each side of the split band? >>>
Well, during A/B experimentation with two 15" FSL test models the high and low band 1162/46 Litz wire turns were adjusted to cover different frequency ranges on each model, then the two models were tested against each other in actual weak signal daytime DX runoffs. Whenever one model would excel, both models were equalized to the optimal setting, then the turns would be adjusted again to a different range on one model, and the test repeated. Eventually the best Litz wire turns configuration for both the high and low bands was determined, and both models were finally secured in this configuration.
73, Gary

I did note a bit of a "sag" from all that additional weight. I meant the FSL...not you of course :) I might have missed this in the file archive but....How are you determining the optimum amount of turns of litz for each side of the split band? Lol...Kiwi Cliff...good one...V
