Neil, KJ6FBA


From the documentation: When selecting a page of memory the ATS-909X will scan and select the memory preset for the strongest station. At certain times the strongest station may not be from the country/station of the page selected.

So, the ATS *will* scan its memories, but it is a limited scan of 9 presets per memory page.  There are a total of 39 memory pages for SW.

are there any worries about introducing static discharges-not noise- into the skywave innards.   where do you hook the new plug into the radio??

what about doing similar thing  for an external sw antenna???

thanks    clyde

Tony brought his PL-360 yesterday and I had a chance to both see and use it.   It works well and in his case, the nulling capabilities are impressive.  The antenna was able to change azimuth's quite easily so perhaps a brake mechanism would be a worthy addition.

I have a spare 7.5" Amidon ferrite bar.  Guy, are you shooting in the way of coil impedance?   Perhaps the same as on the PL-380 project?.... was it 552 mh?

My next project is going to add a 1/8" female, stereo jack to the C. Crane Skywave to input a crate loop.  When the loop's tuning capacitor is fully unmeshed, I connect the modified PL-310 to the Loop VIA the now modified for MW, antenna input on the radio VIA a 12" piece of separated, very flexible, speaker wire.  An 18"/ side Crate Loop outperforms the signal catching ability of a PL-380 w/ 7.5" ferrite combo consistently by 10db.   The Skywave is, IMHO a much more "listenable" radio with its 3rd (or 4th?) generation DSP chip.

Good day to all!

Hi Gary,

I remember seeing this Ebay seller from Greece with a similar posting in July, and it's what gave me the idea to try it out with the Countycomm GP-5/SSB (not an official Ultralight :^)

I don't know if this Ebayer winds a new Litz wire coil, but I used some larger Litz left over from a PL-380/Amidon rod project and matched the inductance with an LCR meter. The assembly barely fit underneath the Tecsun antenna's plastic housing; I had to do some gentle X-acto knife carving here and there. Fortunately the clever screw-on caps help hold things together, after drilling out the caps' centers for the longer rod of course.

It did give a major boost to the signal levels, but as you correctly suspected it was unwieldy due to the small 3.5mm headphones jack supporting all the weight. The lack of any "brake" or lock for the antenna's position was the reason I eventually stopped using this modification and went onto other things (like my current digital readout ICF-EX5MK2 project :^)

I think someone could optimize this larger rod antenna with some sort of friction clutch or "brake", perhaps using your own idea of the stiff, rubber tubing section to provide the friction. It may be best though to fix the antenna's position firmly in place, as it's easy enough to rotate the body of the entire, skinny PL-360 by hand.

Ah... I just remembered what my final step in this adventure was. I flipped the included belt clip for the radio upside-down, so it pointed above the radio. Then I extended the loopstick's wiring with a different 3.5mm audio jack and a couple more inches of wire so it would reach the radio's antenna input. The 200mm loopstick was then tie-wrapped to the inverted belt clip after drilling four small holes into the clip. That combo resulted in a sturdy, but removable support for the larger antenna.

I'd upload a photo, but I no longer own this radio... I think my description of the mounting method is clear enough though.

Hello All,
 
While checking the latest eBay listings I came across this 200mm plug-in upgrade loopstick for the Tecsun PL-360 model, sold for $35.00 (+ $9 shipping) from a company in Greece: 
 
A demonstration video of the 200mm plug-in loopstick's MW performance is posted at
 
Since this type of antenna is very similar to the 7.5" upgrade MW and LW loopsticks that I designed for the PL-360 model four years ago (the article posted at http://www.mediafire.com/view/2cqwsqj0bvajf6k/7.5_inch-LS.doc ) 
I thought that I would offer a couple of comments. The $35.00 price seems very reasonable, although no details are given of the loopstick's coil design or inductance. The design lacks any type of locking system like the rubber hose clamp on the 7.5" plug-in loopsticks, which means that the antenna will rotate around freely in the plug-in socket (similar to a ham radio antenna on a tower, with no brake). Finally, whoever shot the video apparently wasn't aware that whenever you change plug-in loopsticks on a PL-360 you must shift the frequency off slightly and then back on, in order for the Si4734 DSP chip to readjust to the different loopstick inductance, and provide maximum sensitivity. In any case, it will be interesting to see how many sales this company will end up with, and the ultimate performance of their 200mm loopstick design.

Re: Sony ICF-P26

Sorry, no with my hands as they are, I am lucky if I don't drop it, and can change the batteries. The only visible screw on the outside of the case is at the whip antenna base. Looks to be glued shut.

I am also wondering if it has DSP. No trouble tuning the analog radio like the KA321 had, but the AVC is extremely close. What I mean is there is almost no difference in how loud the radio sounds on weak and distant stations and local powerhouses. Like the PL-310, you set the volume once, and seldom adjust it after. It also 'sounds' like a DSP radio, less noise of some types I guess, but it is hard to say. I was thinking of asking for clues that a radio is DSP?  It tunes like analog.

Being a SONY product, and the fact SONY has been making IC chips for a very long time, I would expect these radios to use SONY chips. So possibly SONY is using using something like DSP?

It is on the SONY USA site without a price. I expect it will be found at corner drug stores soon. I do not see any Walkman radios at SONY USA. The one I got from NYC on eBay tunes up to 17, but most of the photos show ones which only tune to 16, and that is what is shown on the SONY EU site. - FARMERIK

Can you open up the Sony to see what DSP chip (potentially) is it using?

I don't know how he did his, but I replaced the short ferrite in mine by opening the plastic cover and carefully unwinding the existing litz leaving it attached to the mini plug. 

Then I put a paper sleeve (reversed masking tape, sticky side up) on the end of a longer ferrite of the same width and rewrapped the original wire on this sleeve. 

Be careful not to do it too tightly, or you won't be able to slide the coil to the center once wound. When you finish, you slide the coil to the center (or off center if you prefer) and reassemble the plastic shell, which will include the plug. The end caps can either be drilled out to allow the longer ferrite to protrude, or you can do what I did: just use electrical tape to keep it all together. That also allows you to give a layer of protection to the protruding bare ferrite. 

The result is much more signal, and I like the ability to spin the antenna while holding the radio facing me. My ferrite is about 6 inches long. I had it in a parts box. I thought about using a longer one, but there is a law of diminishing returns at work here. Another 6 inches would be much more expensive, fragile and probably only a fraction more effective. Once you get beyond signal to noise floor, more antenna is just equal to adding volume. 

I also considered using better litz, but there isn't a lot of room inside the form for thicker wire. It's a compromise, but so is the radio. I use my PL 310 for more critical listening anyway. The band width selection helps so much. 

I did the antenna input jack mod on the PL 310, using the unused half of the stereo input to bypass the on board ferrite and allow the chip to tune outboard loops. So for tough conditions I use that radio and a series of air core MW and LW loops.

Is power-cycling the receiver not sufficient to get the chip to
re-evaluate the antenna?

Also, let me add, that it's wicked cool that the chip can actually do that!! :)

Puyallup, WA Ultralight TP's for 10-17

Despite the lackluster reports from Victoria this morning's session did have an unusual offering-- the best signal from the 1035-CNR1 synchros ever received here (fair) around 1345. That was a pretty bizarre reception, though, seeming to go against the trend of a mediocre morning for everything else.
 
Two band checks at 1300 and 1330 confirmed the dreary situation that Colin and Nick had described, with all the Asian signals subdued. The usual NHK big guns and 1566-HLAZ seemed to be struggling, and nothing else was in audio. Figuring that the session would turn out to be a clunker I debated whether to set up the FSL antenna as usual in the back yard, but after hearing an unusually strong carrier on 1035 (with the distinctive, warbling sound of the poorly synchronized CNR1 stations) I decided to do so. Around 1345 these 1035-CNR1 synchros managed a fair peak with Chinese male speech-- their best level ever here in Puyallup. Despite this almost no other Asians sounded healthy at the time, with the NHK big guns and 1566-HLAZ still struggling, and only the 1053-Jammer matching 1035 with fair audio. Around 1400 the Japanese on 594, 693, 747 and 828 finally got untracked, but of these only 594 reached a good level (around 1405). 972-HLCA also came up to a brief good level at 1359, and a weak mix of HLSA and China appeared on 603. Late on in the session both 1575-VOA and 1593-CNR1 came out of the noise to reach fair peaks before collapsing with the other Asians around 1415. Overall it was a bizarre session, without much of interest except the unusual signal from 1035-CNR1 at 1345.
 
972  HLCA   Dangin, S. Korea   Pop music, KBS ID and 3+1 time pips at good level at 1400 TOH
 
1035  CNR1 Synchros   Chinese male speech at fair level (with minor echoes) at 1345-- its best signal ever here

My SONY ICF-P26 just arrived. It certainly is small enough to be an ULR.

Who do I email with the details of how it seems to qualify for ULR approval?

I have done more listening to the larger ICF-306. At night coupled to the BOG AM is very crowded. I logged-

WZON 620 5KW-260 miles
WILK 980 1KW-201 miles
WDCX 990 2.5 KW 302 miles
WRCA 1330 17 KW 52 miles

None are new logs, but are not easy to hear stations by any means here, and it is only mid Oct.

As Colin and Nick have reported Asian signals dropped off somewhat in comparison to yesterday, although a decent sunrise enhancement boosted up a couple of second-tier TP's to better levels. The Japanese big guns and 1556-HLAZ were the only really energetic performers, however.
 
At my 1315 start time only 1566 sounded very healthy, with very good level Japanese speech. By contrast the NHK big guns sounded anemic during the predawn darkness, and the second-tier TP's were completely missing in action. Around 1350 the usual collection of Japanese NHK signals on 594, 693, 747 and 828 began to get a decent sunrise enhancement boost, which brought 594 and 693 up to good levels in and out. 972-HLCA and the 1053-Jammer came out of the noise as well, but never did get much above fair levels. Early in sunrise enhancement the somewhat unusual 1323-CRI also came out of the noise with apparent Russian, but couldn't maintain its weak strength. The situation would have been routine and boring except for a fair mix of 603-HLSA and 603-China that came out of the noise at 1405, and an unusually good signal from 1134-JOQR at 1407, playing instrumental music during the late night in Japan. Other second-tier TP's (558, 657, 738 etc.) stayed down in the noise for the entire session, though, and none of the Japanese big guns matched yesterday's levels. Overall it was a pretty typical lean-season session, although 1134-JOQR's signal at 1407 was the best that it has managed here fro a couple of years.
 
693  JOAB   Tokyo, Japan   NHK2 Chinese lessons at good strength at 1356
 
1134  JOQR   Tokyo, Japan   Instrumental music at good strength at 1407; its best signal here since 2013
