Yes, they certainly weren't designed for easy maintenance. I started taking one apart to look at the RF section, but once I got deeper into the radio, decided to put in in the "when I get a round tuit" list.

 Hi Rick,
 
Very few of these "supercharged" 7.5" Longwave loopstick PL-380's have been built, so there may not be enough DXers owning them to give you some valid answers, or suggestions. Most of these models currently in use were constructed here and sent out to others in 2011 (to Kevin, Rob and Patrick), although a new model was sent out to Stefano T. in Italy this summer. All of those models were tested out before shipment, and none of them (or my own 7.5" Longwave loopstick PL-380) had the symptoms that you describe. I assume that you removed the stock loopstick from the radio before installing the 7.5" transplant-- if not, that stock loopstick could easily pick up noise from the nearby digital display, which would be picked up by the transplant's Litz wires as they passed over it.
 
One additional fact may be of interest to you, however. This summer I constructed a new 7.5" medium wave loopstick PL-380 to give to Patrick Martin of Oregon, as I passed through his neighborhood on the way to the Cliffs. This was to replace his old-design model made of 40/44 Litz wire, which although of slightly less AM sensitivity, had given him good service for two years. After trying out the new model he complained about digital processor noise in his new PL-380, which did not exist in his old PL-380 model (which he had given back to me). After checking his old model against a brand new PL-380 received this summer from Kaito (via Amazon), I found out that the brand new PL-380 did indeed have some digital processor noise that did not exist in Patrick's old model, purchased in 2010. For this reason, I have been checking all the new PL-380's which arrive here for this additional digital processing noise, and have found that it exists in about half of the brand new PL-380 models. For some unknown reason, the problem seems more prevalent in the models purchased from Kaito via Amazon, than it does in the models shipped directly from China by the eBay seller "Tquchina."

Subject: [ultralightdx] PL-380 screen noise?

 
Hi all, I'm trying to determine if I have a bad sample or if my supercharged PL-380 is acting normally. The radio is hearing its own LCD screen on a large swath of the LF and lower AM band. There ARE frequencies that are dead quiet and it will pick up NDBs just fine so the rig works. How do I know it's the screen? When I touch the screen the noise gets much louder as it couples through my body and into the loopstick. Additionally, when I cycle through the options and display the signal strength, the noise changes in volume and tone (annoyingly). A preliminary attempt to check the shielding of the cpu or screen seems like it will be difficult as it is on the "front" board and will need some extensive un-soldering to get to it.  I have supercharged my PL-380 exactly per instructions and I'm a skilled builder so I doubt there is any reason to suspect a problem with the build. I also tried re-routing the Litz wires to get them off of the board to no avail. I hear the noise on both my LF and AM loopstinks. Now this IS a DSP rig and I don't know if the rf gain or AGC is getting pushed up when no signals are being heard causing the problem. I'd appreciate some feedback on this before I go and purchase a second PL-380 and void its warranty just to find the same performance.

Could be a batch that all have a missing capacitor somewhere, that made it through QA.

Would be worth comparing serial numbers.

I just finished repairing and aligning an Icom IC-R71A that had an annoying "chuffing" sound every 10kHz as you tuned around. Turns out it was missing a decoupling capacitor on the PLL board and had come out of the factory like that. Yikes!

Tim,

I have the DE1126, which appears very similar to yours but adds an mp3 recorder. Mine works well on FM; MW is ok; SW is pathetic. Maybe I got a defective one, or maybe the mp3 recorder interferes with mw and sw. glad you are enjoying yours!

Puyallup, WA Ultralight TP's for 10-14

Hello All,
 
 
What sounded like a very promising band around 1310 hit the skids here around 1330, with Asian propagation seeming to take a swoon just before the usual peak sunrise enhancement time. Early on (around 1315) there were many potent signals from the big guns on 594, 747, 774, 828, 972, 1053 and 1566, along with some interesting mid-band Chinese signals on 918, 927, 936, 1017, 1035 and 1044 kHz. 558-HLQH, 603-HLSA and 738-BEL2 were in and out with fair signals, and 657-Pyongyang was managing a fairly vibrant tirade. This all started to change pretty dramatically around 1330, when both the big gun and second-tier Asians started to slide downhill-- leaving everything sounding pretty mediocre by 1400. The big guns on 594, 747, 828 and 972 were still around at anemic levels, but the second-tier Asians had dived into the noise for good. This was the first session this season that had such a dramatic collapse, without any sunrise enhancement at all.
 
 
Before the band hit the skids in mid-session 1044-CRI managed its best audio of the season here at 1320, with its Japanese service at a fairly vibrant level. The best Asian signals were from 747-JOIB, 774-JOUB and 972-HLCA, which all had excellent audio early on (around 1315) before propagation went into the tank. Some fair mid-band Chinese signals on 918, 927 and 936 were also showing promise around 1320, but I figured that they would all rise up dramatically around 1400 during peak sunrise enhancement-- so they were pretty much ignored until the propagation swoon took them out prematurely. Overall it was a pretty frustrating session, but at least 1044-CRI's seasonal best audio at 1323 was recorded before the band went into the clunker mode.

Sony radios are manufactured by an affiliated company based in Japan, namely
Towada Audio. "Made in Japan" Sony radios (e.g. ICF-SW7600GR) are produced in a
factory in Akita Prefecture, Japan, and "Made in China" Sony radios (e.g

Puyallup, WA Ultralight TP's fpr 10-13

Gary DeBock
 

Hello All,
 
Nigel is certainly correct that this was a very unusual morning. At 1320 a quick check of the band (on a modified ICF-2010 spotting receiver) revealed the Asians to be in full clunker mode, with only a few wispy carriers from big gun TP's like 774-JOUB and 972-HLCA. Figuring that there was no reason to sacrifice sleep by chasing anemic audio from such stations, I made a final check at 1340-- only to discover that  clunker propagation was still in full force. Most likely a few big gun Asians made it out of the noise during full sunrise enhancement from 1400-1420, but such a prospect wasn't sufficient at motivation at 1340 UTC to get up, go out into the cold back yard with the 22-pound 12" FSL, 30" loopstick ICF-2010, 7.5" loopstick PL-380 and Sony ICD-SX57 audio recorder... so the wise decision was made to stay in bed,  leave the big gun TP chasing to others, and read the full description of their kind efforts later (after sufficient sleep), at a much more convenient hour.

Dear Gardner,


I think that Tecsun's worldwide distributor based in Hong Kong also deals with Degen products. It is unusual to take charge of products from a rival company, but I suppose it is due to management efficiency.

"Made in Japan" Sony radios (e.g. ICF-SW7600GR) are produced in a factory in Akita Prefecture, Japan, and "Made in China" Sony radios (e.g ICF-S10MK2 and SRF-59) are produced in a factory in Dongguan City, Guangdong Province, China.

Also, Degen might be weaker quality control than Tecsun or Sony. My first DE321 tuning pointer indicates at around 675kHz when receiving 711kHz HLKA (KBS Radio 1 Seoul), while the second one's indicates at around 800kHz when receiving the same broadcast. In addition, the sound from the built-in speaker is slightly different. The speaker sound from the second one is slightly richer.

I heard that QC problems sometimes occur at DE1103, etc. Degen produces radios that are inexpensive, still cheerful in performance like Tesun does, but Degen should make more efforts on QC.

Mr Gardner,

I don't believe that Degen and Tecsun are the same company. The company names and locations are different: Tecsun in Dongguan and Degen in Shenzhen.


However, Kaide and Kchibo (who make "cheap" and poor SW radios) are either the same company or the highly afflicted manufacturers to each other, though.

Puyallup, WA Ultralight TP's for 10-12 (Conclusion)

Gary DeBock
 

Hello All,
 
 
The low-band Asian signals were much improved here this morning, with overall results very similar to those reported by Bruce (although with a slightly different cast of leading characters). Whereas Bruce had 594, 747, 774 and 972 with good audio, here it was 594, 603, 657, 747, 972 and 1053 with the best signals. Low-band second-tier Asians were particularly vibrant, with 531-JOQG, 558-HLQH, 639-CNR1 and 648-VOR all reaching fair to good audio at times. 648-VOR was unusually persistent from 1330-1400 with its Chinese service, managing to get through the oppressive 650-CISL splatter for about half an hour. 
 
 
The strongest big guns here were 594, 747, 972 and 1053, with 972-HLCA again producing a monster signal around 1355. 657-Pyongyang was strong and persistent with its Korean tirades around 1410, and 738-BEL2 was back with fair Chinese female news at 1402  As reported by others, the high band never seemed to join the party, with 1134-KBS, 1566-HLAZ and 1575-VOA anemic at best. In keeping with this trend, the second-tier high band stations on 1323, 1377, 1503 and 1593 never got out of the noise here, while the Chinese middle band stations on 936, 963, 1017, 1035 and 1044 were struggling to come up with any audio at all. Overall it was a pretty exciting session, with the low-band Asian mainland stations showing some energy for the first time in about a week. 
 
 
603  HLSA  Namyang, S. Korea   Strong Korean
            pop music at 1352, // 558-HLQH
 
648  VOR  Razdolnoye, Russia   Fair Chinese
            service at 1335 through CISL splatter
 
738  BEL2  Penghu, Taiwan   Fair Chinese news by
            female announcer at 1402 (standard programming)
 
972  HLCA  Dangjin, S. Korea   Usual monster signal at
            1355 with Korean pop music and female-male talk;
             best TP signal of the morning
 
 
73 and Good DX,

Re: Proper DX

I think Bruce and others are correct in that it's individual and ought to be fun.

I maintain a log, as much for reference as anything else, but I rarely bother with
totals of anything, because, as Bruce points out, conditions change dramatically
in terms of interference, stations causing QRM and of course equipment. Some
don't even keep formal logs.

Bottom line, whatever gives you pleasure from the hobby is good.

I've been following the "Proper DX" thread, and it's interesting to learn how various DXers evaluate their catches.  I prefer to keep it simple.  I maintain two separate online logbooks; international (outside Canada and U.S.) at http://www.bamlog.com/2013logbook.htm and domestic (Canada and U.S. only) at http://www.bamlog.com/domestic2012.htm.  The domestic logbook was restarted in 2010 and the international logbook is restarted annually to retain relevance.  While it can be interesting to read about DX from 30 or more years ago, it lacks relevance with conditions today, i.e. receiving 640 KFI as an east coast regular in 1975 vs. co-channel interference today, so I keep score simply by a total of domestic reception this decade including locals.  International DX is more fluid due to atmospheric conditions and the number of nations switching to FM and digital platforms, so I restart the log annually to better reflect the current status, but I don't keep an overall total score like domestics.

To me, most importantly "Proper DX" includes sharing your logs with the DX community in a timely manner so that others may benefit from your experience.  Share your logs via email lists like this group, club newsletters such as those published by NRC and IRCA, and online if you have website publishing capability.  It's a good way to grow the hobby too.  The point value one assigns to DX is secondary.

Last but not least, "Proper DX" means having fun.  Enjoy what you do.  Don't get too bogged down with keeping score or keeping up with the Jones'.  I especially enjoy listening with my cat curled up in my lap, while sipping Newfie Screech on ice or a cup of coffee.  And it's fun to get together with others a couple times a year on DXpeditions.
