Re: Thoughts on antenna mounting to Gary DeBock
Hi Phil,
<<< I'm making a longwave antenna for my PL380. Any thoughts on mounting the antenna on the outside next to the MW antenna? The MW antenna is internally wired to a phone jack. >>>
If your MW antenna is outside of the PL-380 cabinet, Phil, then I assume that you have attached it to an orange plastic frame, as called for in the PL-380 "Supercharging" instructions posted at http://www.mediafire.com/view/du3sr5cd9thqvau/7.5inch-LS-PL380.doc
In general, though, it's not a good idea to have two independent loopsticks in close proximity, since they would tend to interact with each other. A better approach would be to use a dual-band loopstick, such as the MW-LW loopstick designed for the PL-380 by Steve Raztlaff about three years ago. Using a multi-coil system, Steve was able to get good PL-380 reception on both MW and LW, although I can't track down his original design in my files. I'll post this response on the Ndblist reflector as well as the Ultralightdx list, in the hope that Steve will see and respond to it. As I recall, Steve was able to get excellent reception on the MW frequencies with his dual-band loopstick, and LW reception almost as good as the dedicated PL-380 LW loopstick that I designed in early 2011.

Do you thing the antennas be opposite each o

Re: November 8-10 Grayland Ultralight DXpedition Article
Paul Blundell
Thanks for posting this Gary, made for a really good read. Paul From: D1028Gary@... [ultralightdx] Sent: 1/12/2014 5:49 PM To: ultralightdx@... Subject: [ultralightdx] November 8-10 Grayland Ultralight DXpedition Article
Hello All,
For those interested, a full article describing the 3-day Grayland Ultralight DXpedition conducted with the new 17" FSL antenna on Veterans Day weekend has been uploaded at http://www.mediafire.com/view/k7boymq62q2p5v1/November_2014_Grayland_Ultralight_DXpedition.doc , and will shortly be uploaded to the Yahoo Ultralightdx file site. Describing the rare chance to take oversized items like the 17" FSL antenna and the 30" loopstick Sony ICF-2010 model to the ocean coast, the article includes multiple photos of the TP-DXing setup at the end of Grayland Beach Road, along with MP3 links for 39 Asian DX recordings made at the site. Thanks very much to Phil Bytheway for already posting summary articles of the DXpedition to the club bulletins-- this full DXpedition article was something that I had not planned to write, but suddenly decided was more interesting to complete than chasing wispy TP audio during dreary sunrise DXing sessions at my landlocked home location :-) 73 and Good DX, Gary DeBock (in Puyallup, WA, USA) |

Ultralight DXing Report - Launceston Tasmania - 6/12/2014
Paul Blundell
Date: 6/12/2014 Time: 19:00 – 19:40 Location: Home, Launceston Tasmania Radio: 7.5” Loopstick Tecsun PL-380 Total stations logged: 36 New stations logged: 0 Furthest station logged: 2RN (New Castle) 1032km Notes: Tonight I managed to grab a 40 minute block of time to myself, our daughter was born this week so I have been spending a lot of time at the hospital, her and my wife have come home today so things can now become the “ new” normal. For the foreseeable future most of my sessions will be at home or very close by. In the 40 minutes I had I was able to log 36 stations, all of these I have logged previously. All the normal Tasmanian / Victorian stations I would expect to hear came in with fair to good audio, some NSW stations were also logged with the top end of the band between 1152kHz and 1512kHz being where these were mostly found. A number of these NSW stations maxing out the PL380's signal meter. I did a quick listen on my NZ check frequencies but no signals were heard, given the early time this session was undertaken this was to be expected.

Re: moderating spam
Actually Michael….it's much simpler than that even….we have "One Person" in the administration who can remove the spammer from the List…and at this time we just can't contact him!!! As soon as we can contact him….the spammer will be gone!! We would like to have 2-3 People who can control the ship….but because the Person who co-founded the Group and had control of the Buttons we need to push has passed on (The Late John Bryant)….we can't add administrators to the Group. That's why we have the Back-Up List should things get too hairy on this one…and so far since 2008…I think things have been pretty good here, and not worth moving everyone to a new list!

Check the tree-structure for infiltrators, as far as you are able. In the meantime I have no problem : I just delete. Unless you follow the link, there is near-zero risk. Group members should always ensure protection is updated.

Re: Ultralight quality control: Sangean DT-400W
David,
The Sangean DT-400W was one of five Ultralight Radios which were given very thorough reviews in the 2008 Ultralight Radio Summertime Shootout article, posted at http://www.mediafire.com/view/2t5godzzyaw/2008UltralightAMRadioSummertimeShootout.doc The other Ultralight Radios covered in the review were the Eton E100, the Sony SRF-S84, Sony SRF-M97 and Sony M37W models.
The Ultralight Radio Shootout reviews were some of the most popular articles that I've ever written, and there were also major "Shootout" reviews in the Spring of 2008 and in the spring of 2009. These pocket radio reviews really helped the ULR craze get off of the ground.
I personally have two of the DT-400W models, and both of them have worked very well during the rare times that I've turned them on the past 6 years.

Re: Ultralight quality control: Sangean DT-400W
Rik
I have literally hundreds of portable radios, and there are many times more failures in Sangean than SONY, so mostly I buy SONY now days. Untimely 'deaths' of SONY radios are extremely rare in my collection and mostly when they employed new technologies years ago.
More and more SONY radios are actually assembled in China, but use SONY chips [ I think]. I have have many non ULR's from SONY which do a very good job in the $50 class. I had good luck DXing with the ULR model ICF-S22 and the AM only ICR-P15 certainly hears a lot of stations and would be interesting to DX with if approved.. Both my first two versions of the CCrane radio had total failures just out of warrante involving the displays, so Sangean certainly has had time to correct that sort of problem over the years if they wanted to. -FARMERIK |

Happy December to all & thanks to Paul for the kinds words about what i've been hearing lately..a good, mostly noise-free location (with a semi-spectacular ocean view) & the PL606 are a nice combo (occasionally patience & imagination help, too).. 7465 (Kranji)/17640 (Ascension) BBC 1635+ 30 Nov. Sat back & enjoyed play-by-play of the Tottenham/Everton match. 15420 BBC (Meyerton) 1545+ 2 Dec. Sports news w/ feature on the Trinidad/Tobago women's soccer team getting close to qualifying for the World Cup, weak w/ //7465 much better. 15940/15970 CNR1 1553-1600* 30 Nov. Jamming SOH here, on 7385 echo-jamming RTI, & 7570 jamming VOA (after 1600) + regular sked on 7305/7365. 13810 RTI (Issoudun) 1641-1657* 30 Nov. EG with closing ID..Aoki says jammed, but it sure doesn't sounds like it. 11517 VoT (Dushanbe-Yangiyul) 1435-1500* 1 Dec. Site presumed & apparently an alternate freq. to 11512..TB chat w/ nice musical interludes..CNR1 jammer only a vy weak carrier on 11510 @ 1435 but much stronger by 1455 (just in time to close @ 1500 with a flourish), 1439+ 2 Dec. as well, so perhaps this is a "permanent" freq. change? CNR1-11510 jammer much stronger today, but just as ineffectual. **11530 RP (Islamabad) 1435-1500* 28 Nov. Thanks to Ivo Ivanov's info on the HC-DX site, my unID seems to be Pakistan--seriously disturbed audio/wobbly carrier..recheck 1442-1500* 1 Dec. found much cleaner audio but modulation still very sub-par..occ. Urdu words & some songs made it through..sked 1330-1530 & irregular @ best, but still a treat to hear..2 Dec. RP only "imaginary-level" audio @ 1440 check. 11635 TWR-India (Yerevan-Gavar) 1503-30* 1 Dec. Chat & "sub-continental" style hymn-y tunes, Post Box #s for listener comments @ :15, more chat & slightly more "Bollywood" style tunes to BOH w/ TWR website/POB in Maharashtra, music box IS & off..sked in Gamit 1500-1515, Mouchi 1515-1530 on Mondays & Urdu 1530-1600, but unless they started the Urdu programme pretty late, it wasn't on today. 15580 VOA (Selebi-Phikwe) 1539+ 1 Dec., 1532+ 2 Dec. Listeners' requests (including MC Hammer "Can't Touch This", Britney Spears, Taylor Swift) during Larry London's music show..sked 14-16 & usually puts in a nice signal daily..also hearing (in a wishful thinking sort of way) VOA (Selebi-Phikwe) on 4930 in // (even with the PL606 hooked to the 6m Xwire, the signal is extremely marginal @ best), still, the possibility of a ULR logging of a 60M African via LP is intriguing. Hope everyone has a fine week..good listening, y'all.. Dan WB6FJD |

I realize that it is a great Ultralight and there are certainly a number of very positive reviews to support that viewpoint - going back to the 2008/2009 Ultralight Shootouts (see the group Files section). As a non-DSP Ultralight, out of the current models it would appear only second to the iconic (and pricier) Sony SRF-T615. I have seen reports of the issue with the volume control that occur with some units, including (as per some reviews on Amazon) failure of the volume control itself. So between that and the display reports, I thought that I would throw the question out. These problems would seem to be isolated, but worth noting. It's useful to get a feel on all Ultralight radios in general - both on older units to see what issues occur over time and on more recent production units, to help those Ultralighters (like me) that are tempted to add another one to the shack. It's always good to be an informed consumer. 73 David On Nov 30, 2014, at 11:09 PM, Stephen Ponder stephen_ponder@... [ultralightdx] wrote:

Re: Supercharging the ICF-2010 SSB Receiver

Hi Gary,
Thanks for the update.
No pressure. I was just concerned that I might have missed it.
I realise it requires a lot of testing, and we are all grateful to you for
devoting so much time [and ferrite] to the issue. I'm happy that it will be
worth the wait.
Best Wishes

No, you haven't missed anything yet. The major revision of the May
2008 article (at http://www.mediafire.com/view/404c61oxxbd992n/SuperchargingtheICF2010LargeComplete.doc )
has been delayed due to limited time for testing out various Longwave upgrade
loopstick models.

Hi David,
<<< Did I miss this?
My 2010 emerged from a storage crate earlier this year, and I was going to try the 'new improved' loopstick. I didn't see the update, and couldn't find an article in the archive.
If I missed it, could you resend the link? >>>

The upgraded Medium Wave loopstick (based on coil inductances from the stock model) was the easier part of the project, and was wrapped up fairly quickly. It is composed of two Amidon 7.5" Type 61 ferrite rods, wound with 100/44 Litz wire, and supported on a 16" orange plastic frame glued to the top of the ICF-2010. The Longwave loopstick design is the more challenging part of the project, starting pretty much from scratch in creating an all-new loopstick design radically different from Sony's stock antenna. The only way to do this is to create multiple Longwave loopstick test models and test them out (in competition) with signal generator inputs-- a very time-consuming process. This was the same process used in designing the all-new Longwave upgrade loopsticks for the Tecsun DSP Ultralight models (like the PL-380) in early 2011.

For those who are interested, a major update of the May 2008
article (posted at http://www.mediafire.com/view/404c61oxxbd992n/SuperchargingtheICF2010LargeComplete.doc ,
to greatly increase the MW and LW band sensitivity of the classic Sony ICF-2010
SSB receiver) is in the works. The updated article should be completed during
the Fall season, and will provide specific instructions for transplanting
and securing a much more sensitive loopstick into the Sony portable's
circuitry. The new loopstick will be based upon recent Litz wire
improvements.
