Re: All-Time Worldwide Ultralight Radio DX Distance Record Broken

I'm a Show Room Stock ULR guy so really don't have a horse in this race, but a thought popped (struggled?) into mind.  I don't have my references at hand, but there is a gazzilion watt Moroccan broadcaster on, I believe, 207. It was occasionally arm chair copy in northern California where I used to live.  I would think this would be doable from an arc of roughly Broome to the York Peninsula in Australia and would add some kilometerage to the new record. I've done some casual listening in Broome, Darwin and the base of the York Peninsula and it is a kick.

New Zealand certainly has ocean cliffs every bit as good as Rockwork 4, but the U.S. still seems to have the edge in DXer fanaticism (i.e., in the willingness to set up on them). Even the Perseus-SDR enthusiasts Chuck and Tom seem to be adjusting very well to the Rockwork 4 site.

Re: Lower RFI TV, LED or LCD Screen or something else???

Paul Blundell
 

We have multiple TV's in our house, some are "good" as far as RFI go, others cause some issues. Multi-way power boards also seem to be an issue....

It does not have RCA video input which our present Cox cable box needs. We will have to check our next bill to see if we own or rent the cable box. It is the first one we got when cable became available here in our very rural location as a promo offer.

I really know nothing about TV especially modern sets. I did build a Heath Kit color TV for some one back in the 1960's. What ever I knew then I forgot. It will be for the news and sometimes History/Natl. Geo/Discovery, we don't follow sports or watch movies much, which I guess are why people want really large screens.

Thanks for all the replies so far. My son picked this one from New Egg in a quick search after measuring the cabinet it MUST fit in. The cabinet opening  is 26.25  inches wide, and plenty tall enough for the wider and  shorter modern sets.

Hi Chuck,

Thanks very much for your generous comment on the 558-6WA reception.

Instead of getting too comfortable in holding the record, however, I'm just waiting for my ULR-DXing buddy Tony King of Greytown, New Zealand to receive something like 693-BBC in the U.K. to get the record back :-) Unlike here in the U.S., medium wave propagation to New Zealand is phenomenal.

Several points in these posts are excellent. 39"/120Hz sounds about right, replace any power-switched device with Xformer, and reduce contrast and brightness. I would also look for 1080p resolution at the 39" level... 60Hz is OK as a tradeoff.

Change to my blog

Paul Blundell
 

Some people might have already noticed this. Over the weekend I have migrated my blog, all posts and content from it's old URL (http://ultralightdxing.blogspot.com.au) to a new site http://vkpc7pb.blogspot.com.au/

Over the past few months my interests have changed slightly, while I am still very active in the ultralight dxing hobby I am also expanding in to some new / different areas of the radio hobby, I will be much more actively blogging about this so the time was right to change my blogs names and URL to something that more closely reflects what I am doing.
The old URL will redirect to the new site for a period of time.

Software - DB4SWDX

Paul Blundell
 

I have always had an interest in computer programming, recently I have combined this with my hobby of radio dxing to create my own custom radio loggings database, this is called DB4SWDX (Database for Shortwave DXing).


This database allows you to enter and then search your loggings of shortwave stations, this can be easily modified for Mediumwave or FM DXing loggings. 


This program is written in Just Basic, it is fully self contained in it's own folder and does not require any other software to work. I have added a couple of "nice to have features":

- The database file is encrypted so that other programs can not access / damage it.

- The database is automatically backed up each day, the backup files live in the "Backups" Folder.

- When entering new data the previous entries data is set as the default, this makes data entry easier and faster as only the data that is changed needs to be entered.

- When undertaking a search, the search results are saved in the "Reports" folder for easier access / posting to websites or forums. 


More details and the download link can be found here: http://vkpc7pb.blogspot.com.au/2015/08/software-db4swdx.html

Re: Lower RFI TV, LED or LCD Screen or something else???

I once took a Degen1103 tuned to 7MHz for a  walk around my block.  From the street,  I could tell every house that had a TV in use and I could pick up one plasma TV from five houses away.   

When selecting a new TV, why not take an ultralight tuned between stations and listen to the RFI emitted by each TV (and power supply)?  Noisy, switch-mode external power supplies can be replaced by transformer-based, analogue regulated power supplies.

Subject: [ultralightdx] Lower RFI TV, LED or LCD Screen or something else???

 

It may be time to finnally replace our 27 inch Zenith CRT TV which is probaby more than 20 years old. Both it and the cable box cause RFI, each less when turned off and none when unplugged. I am looking for a fairly cheap plain TV just for use with cable. I think  there are both LCD and LED displays, but I am not sure. It has to fit in the corner cabinet we have which should take no larger than about a 30 inch diagonal screen. What sort of screen is likely to cause less RFI ?

Our cable box is pretty old, and only has an RCA jack video output. I still have to look into if Cox Cable would replace it with a more modern one, and at what cost. I believe HDMI is the new standard, and RCA for video  is hard to find now. - FARMERIK

Technically, yes. However the industry, users, even engineers at one time or another drop to calling typical LCD video displays and televisions "LED", even though some for some reason many would like to see their very souls rot...but all are forgiven.

Many OEM's call them LED televisions, as too many humans are alive that remember the now older LCD screens for electronics, where the majority of those were "weak", dismal and "inferior" contrast compared to today's LCD and LCD panels with LED back-light.

In many cases, true LED panels are best suited for outdoor or very large indoor viewing, as the almost stunning brightness, contrast and other perceptual emanations would ruin ones eyes in short order.

So-called LED TVs are LCD with an LED backlight. Older LCD TVs used a fluorescent backlight.

LCD TVs generally have lower RFI than plasma TVs. Fortunately for radio listeners, plasma TVs seem to be going away, although they generally offer better video performance than LCD TVs of the same price, especially with respect to black level.

Keep in mind that the size of a 16x9 TV must be multiplied by 0.75 to get the equivalent 4x3 TV. So a 30" 16x9 TV is equivalent to a 22.5" 4x3 TV, as far as image size (height) is concerned. A 36" 16x9 TV would have the same image height as a 27" 4x3 TV. If you're used to a 27" 4x3 TV, you may find a 30" 16x9 TV too small.

ALL TV's, old or new, emit some measure of RFI / EMI.

We have done well with a "not too big, just right for us" 39 inch / 99cm Vizio 120hz LED HDTV TV unit, and it's going on four years old.

EMI and RFI from the Vizio are very minimal, and when we are rarely cleaning it inside, the reason being that Vizio uses a lot of common-sense shielding in at least this line of their video products.

Also, the TV unit is upstairs, somewhat away from the Computer and Communications Dungeon, which is happily located downstairs at our humble abode.
 
Hope this is of some assistance.

Rockwork 4 DXpedition-- Top Ten Signals from the South Pacific

Gary DeBock
 

Hello All,
 
Exceptional propagation to both New Zealand and Australia made the recent Rockwork 4 ocean cliff DXpedition (from August 6-10) one of the most thrilling ever conducted. My DXpedition partners Chuck and Tom both set up small broadband loops for Perseus-SDR spectrum capture at the narrow Highway 101 turnoff (with a plunging 400 foot sheer cliff), while I chased South Pacific DX with a modified Ultralight radio and monster (17") FSL antenna. A photo of the DXpedition setup at the cliff on August 7th is posted at https://app.box.com/s/fa2heca0v3ll2umbc84ko7zq2oj9k8uy 
 
Posted below are links for the ten strongest DU stations heard at the ocean cliff site with the 7.5" loopstick C.Crane Skywave Ultralight radio and 17" FSL antenna. Thanks to my DXpedition partners Chuck and Tom for sharing information on DX catches at the site.
 
567  RNZ   Wellington, New Zealand  (50 kW)   Consistently the strongest Kiwi station on the band each morning, this was a big change from last year (when 531-PI was the top signal). This big band music on 8-7 was typical of the station's strength.
 
576  2RN   Sydney, Australia  (50 kW)   A powerful signal when Aussie propagation kicked in, but MIA when New Zealand was favored. Playing a variety of exotic music, its strength made identification of the ABC RN network parallel signal 585-7RN possible during good propagation
 
603  Radio Waatea   Auckland, New Zealand  (5 kW)    Maori language broadcaster parallel to 765-Kahungunu during early mornings in NZ, it often hit S9+ peaks during favorable Kiwi propagation. This awesome signal (with beautiful Maori music) was recorded at 1244 on the first day (8-6)
 
702  Magic   Auckland, New Zealand  (10 kW)   Depending on propagation, this new-format station (ex-Radio Live) playing classic oldies was either running wild over the Aussie co-channel 2BL, or showing up with anemic signals far underneath it. This S9+ recording was made during awesome Kiwi propagation on 8-7, during which the station sounded very much like one of the Oregon coast locals
 
738  Radio Polynesie   Mahina, Tahiti  (20 kW)   Blistering strong signals usually showed up from this French language blowtorch once each morning, whose R&B music seemed to get a boost whenever the Kiwis were favored. This awesome recording of African and French pop music was made on such a morning, at 1307 on 8-7
 
765  Radio Kahungunu   Napier-Hastings, New Zealand  (2.5 kW)   As always, this Maori-language overachiever had incredible signals for its 2.5 kW power. Who would ever have thought that this near-S9 level Maori language music came from such a low power station? Another of the wackiest ocean cliff mysteries...
 
774  Radio Sport   New Plymouth, New Zealand  (5 kW)   With its relay of the American network Fox Sports News after local midnight, the NZ network Radio Sport stands out like a sore thumb with its Yankee-accented English. This booming signal (way over the Aussie 3LO) was recorded during excellent Kiwi propagation on 8-10
 
936  Chinese Voice   Auckland, New Zealand  (1 kW)   How about something really wacky? This 1 kW ethnic station was giving its best imitation of a Kiwi big gun on 8-10-- something that only bizarre ocean cliff propagation could manage!
 
1008  Newstalk ZB   Tauranga, New Zealand  (10 kW)   Usually managing equal signals with its 1035 parallel, this Kiwi talk station was consistently one of the better DU performers. Here it is on 8-10, way over Aussie co-channel 4TAB
 
1035  Newstalk ZB   Wellington, New Zealand   Powerful talk signals were usually the order of the day with this Kiwi big gun, // 1008 and other frequencies. Although the network concentrates on talk and news, it has recently started playing music as well
 
73 and Good DX,

RE: Jay << Radio is reputed to have nice audio for its size but to be a battery eater...actually that's the only negative I've every heard about it. Have you found that? >>

The YB-500 / Yacht Boy 500 WILL munch on batteries IF one leaves the BOOST on, that straps the audio pwr out to a max of  about 1W.

BOOST is best used with the 9V transformer / linear AC adapter or when powered by non-small battery sources.

BOOST being "off" isn't too bad in that the audio is thusly limited to about 400-500 mw max, then of course the three AA alkaline batteries have a propensity to last longer...:)...

Perchance of interest...Out in the field, I use a 12v-to-9v regulated cable that I snuck an added 2200uf electrolytic filter and .01 + 7809 into. Works quite nicely.

BTW, the YB-500's 9v DC-In is sensitive, or rather is the audio amp, to any remaining AC adapter hum / ripple, and even if using say a LM317 or similar regulator -- set to 9v out of course -- where the 317 totally eliminates any ripple / hum as it regulates...

... I added a 2200uf @ 25v inside the YB-500 case on the 9v leads, and hum or no hum / ripple, it's the cat's meow, and the YB-500 remains a happy camper, er, I mean receiver.

Pssst!  Jay, you never did review this somewhat surprising and perhaps interesting receiver. No time like the present or shortly thereafter (hint, hint)
