Puyalup, WA Ultralight TP's for 10-30

Colin apparently picked the right time to tune in this morning as a clunker band at 1250 and 1330 finally received a potent sunrise enhancement boost. Asians which had been dead rose up out of the noise around 1400, including some relatively unusual stations like 603-China.
 
At first check around 1250 there was no Asian audio anywhere on the band, with only the somewhat unusual 1323 managing a decent carrier. Propagation didn't improve much by 1330, with only a few more decent carriers showing up on 972, 1017, 1044 and 1053. Just before 1400 the Asians got a potent boost, however, with 972-HLCA leading the show with good signals in and out.by 1405. 603-China came up out of the noise all alone (no HLSA) to reach fair levels in and out, along with a presumed 738-BEL2 and 1017-CRI. The Japanese big guns didn't seem all that impressed with the situation, though, with only 594 and 747 reaching fair audio between 1400-1430. The rejuvenated Asians didn't really stick around for long, however, with almost all of them bailing by 1435 here. Best signal of the bizarre session (by far) was from 972-HLCA, with good signals in and out just after the 1400 TOH.

Puyallup, WA Ultralight TP's for 10-29

As Walt and Colin have reported most of the Asians had already bailed by around 1400 this morning, although there were quite a collection of them about 50 minutes earlier. Similar to a Halloween movie, they behaved like ghostly creatures scared off by the daylight, with the exception of 1575-VOA (the sole survivor of a negative sunrise enhancement).
 
At my 1310 start time several big gun Asians were managing fair audio (594, 747, 1053, 1566 and 1575) while second-tier stations on 603, 738, 1017, 1035 and 1044 seemed ready to reach threshold level. The typical swoon happened between 1330-1400, with all of these bailing except for 1575-VOA. This lone station rode out the rest of the session with fair signals in and out until 1445, when it also packed it in. Not exactly an exciting session, but definitely better than yesterday.

Puyallup, WA TP Carriers for 10-28

Gary DeBock
 

Asian conditions took a nosedive this morning as even decent carriers were tough to find. A band check at 1330 revealed only an anemic carrier on 972, with ghostly ones on 1053 and 1566. Increasing daylight at 1405 brought the 972 carrier up to a moderate level, but sank the ones on 1053 and 1566. The 972 carrier might even have reached ghostly audio for a few seconds after that if someone was inclined to stick around and wait for it-- which I definitely wasn't. Usually a clunker band here includes some type of carrier from 738-Tahiti, but even that was too much to ask for this morning. The clunker session at this lackluster location could well indicate a productive DU morning in Victoria.

Re: Construction: how to shield CPU noise?

policow6@...
 

I think the Skywave already has the DSP noises well under control so I wouldn't expect much, if any improvement. But I got a huge improvement on the Eton Field 550 as I outlined in this article:


Eton/Grundig Field 550

and I would expect many other, especially earlier DSP radios with lots of spurious noises, could benefit greatly from some simple shielding.

Re: Mid day Quick shoot out-FARMERIK

That is one I don't have [yet]. It looks nice though. All my SONY radios are very good on battery life, and the ones which come with SONY  batteries, those cells seem to last forever. If you go to one of the SONY Corp.  sites for different continents, they always list battery life on each band in the SPECS sections , some times for both Alkaline and 'regular' batteries. It looks like this new line may replace a number of SONY models. I could not find ANY Walkman radios on SONY USA recently, but maybe I missed them. The P26 is a little larger than the Walkmans, but shirt pocket size, and the newest tiny SONY speakers are better than before.

My ICF-B08 has a speaker opening only about 1 and 1/4 inches, but the sound is not nearly as bad as I expected. That is the wind up / USB charger / LED flashlight or area light / AM FM radio with USA tuning ranges. Lots of other versions on eBay with different  tuning ranges, some have solar cells on top instead of an area LED light. Too thick to be an ULR, like the P26, but about 3X5 inches. Since I had the ICF-B08 out, I plugged in stereo head phones and both channels work, so these new models are not the first SONY portables to have stereo compatible headphone jacks on mono radios as I thought.

There are just SO MANY SONY portables in production, I know I'll never have more than a small % of them.

Only the PL-310ET has the Easy Tuning Method scanning built in. Last time I did both a manually tuned AM 'scan' and used the ETM feature  with the PL-310ET and there was not a big difference in results. So I just did the one PL-310 ETM scan for comparison because I figure band conditions could be different on different days.

Remember this is just a quick test, so all results could be + or - maybe 10%?

I listed them in the order I did the scans too.  If I was focused on fewer radios the scans would be closer in time. Probably would not make much difference. 11:30 AM to 1:00 PM is all Midday.

The three new SONY radio models with extremely similar specs are looking promising. Unfortunately only the smallest, the P26 should qualify as an ULR. In the evening I definitely  hear more on the largest of the three, the ICF-306. The mid size P36 is still on its way from the UK. I will compare those three if there seems to be any interest. I still can not figure out exactly what is different about them as I tune from station to station.

Have you tried the SRF-18? A just-larger-than-ultralight with stereo speakers. I had gotten once just before the last big NEUS storm and is ran for days on batteries when we had no power. Handled very much like a grown-up SRF-59 with speakers.

Thanks - sounds like a plan.

question.  was the survey done using the radios scanning features or going up the band by hand???    thanks   clyde

Re: Construction: how to shield CPU noise?

I added some shielding recently between the boards of the C. Crane Skywave radio, and have made similar additions to other portables before. My usual approach is to target the DSP chip first of all, and DC-DC converters or display driver chips if I can identify them.

Sometimes the extra screening works best if it is floating (not connected to a ground point), but usually grounding the shield is the way to go.

Construction-wise, I like to make up a sandwich of thin tin sheet metal with clear plastic tape on opposite sides for insulation. For the Skywave radio I didn't have any more tin sheet metal around so I used a layer of aluminum foil with the tape on both sides. Because I couldn't solder to the aluminum, I made a mechanical connection of a short length of wire under the tape, and then routed the wire to a ground point on the Skywave.

I'm not sure I noticed any noise level improvements with the Skywave, but I felt better knowing I'd added more extensive coverage than the minimal stock shielding. With other radios the improvement has sometimes been dramatic.

Construction: how to shield CPU noise?

m_a_schuster
 

I'm not talking about noise from a nearby computer. I'm referring to hash generated by the radio itself, which then finds its way into the audio output.

 

Rare on Tecsun radios, I've seen it with cheaper brands but most especially with Degen models. Also Kchibo. Why some brands/models handle it well, and others not, is a mystery to me.

 

Sometimes it can't be fixed easily. The Ccrane pocket radio suffers from it. Their solution: add a button to turn of the display. Hmm. Well, it works.

 

Case in point: the Degen DE-11 (Kaito KA-11), an aging, tiny little PLL multiband styled like previous better-made Sony models. All of MW, and a good portion of SW, is drowned out by buzzing unless you have an S9 signal.

 

If one would attempt to add a shield, where would you start? At the source (CPU? display driver chip? how to identify) or the target? Any generic pointers from someone who has successfully tackked this kind of thing.

Just a 'quick' AM scan comparison from the same spot in my radio room with the radios held in the same direction just to be fair. All 'understandable' stations counted, which is subjective. I did not take the time to slowly  turn 90 degrees on each frequency  and get more stations. Testing both analog and digitally tuned radios would have been hard not to miss some without taking hours to complete the test when band conditions might have changed. This took about 1.5 hours 11:30 AM to 1:00 PM local time Mon 26 Oct 2015.

PL-600=32
PL-310ET auto scan=16
CC Pocket=13
SONY ICF-M260=32
SONY ICR-P15=25
SONY ICF-P26=40


Just to describe the SONY models-


ICF-M260 On the market for years, digital. Selectivity not good as strong stations can be heard 10 KHz away. I was surprised how well it did. It is just about the max size for an ULR. Around $40


ICR-P15 acts completely analog, AM band only, sold in Japan for at least a few years and some times seen on eBay around $30 Shirt pocket size well under 20 CID.


ICF-P26 This is a new model sold in Europe and Asia and listed on SONY USA. eBay under $25.

Puyallup, WA Ultralight TP's for 10-26

Gary DeBock
 

As reported from Victoria there were some moderately interesting Asian signals this morning, with better variety than over the weekend. The mid-band Chinese stations on 1017, 1035 and 1044 made weak appearances here around 1330 while the usual NHK big guns struggled somewhat to get out of the noise. Like in Victoria 1575-VOA was the star of the session, reaching fair to good levels both in the predawn darkness and after daybreak.
 
The multiple CNR1 stations on 1035 managed a fair, warbling carrier at my 1320 start time, and came up to poor audio (with their typical echoes) shortly thereafter. About the same time both a presumed 1017-CRI and 1044-CRI managed threshold audio, but neither stuck around for more than a few seconds at a time. 972-HLCA, 1566-HLAZ and 1575-VOA all had good peaks in and out during this predawn darkness, but the Japanese big guns were unusually subdued. A moderate sunrise enhancement around 1410 brought 603-HLSA out of the noise to reach a temporary fair level, while the mid-band Chinese stations sunk back into the noise. 594-JOAK and 747-JOIB joined 972-HLCA and 1575-VOA with fair to good audio peaks around 1415 while a presumed 738-BEL2 and 1134-JOQR came out of the noise to reach brief threshold audio. That was pretty much the story of the session, with several weak Asians providing more variety but no really strong TP stations showing up anywhere on the band.

Tunes and behaves differently than the SRF59. Probably competitive with it, but I no longer have the walkmen here to compare. It is close enough so it would take quite a bit of time DXing to compare them. I could do additional day time station counts, besides the PL-310 and R9012, but I have no idea what other radios people are interested in, and I don't have all that many.  I should have an ETON Traveler III here, but haven't seen it  lately.

I spent hours DXing with the SONY ICF-S22 and never heard any interest it that after I posted results here. I'd be glad to do a station count though. Just ask if I have the radio you have. - FARMERIK


Re: ETON Traveler III MISS tuning- FARMERIK

Hi FARMERIK,

Mine does the same thing. It's annoying. I have heard of others having the same problem. Seems to be the nature of the beast.

It's a beautifully made radio otherwise. They really skimped on the tuning encoder. I expect it will fail totally in short order.

ETON Traveler III MISS tuning- FARMERIK

My ETON Trav III miss tunes either by skipping steps or not responding to turning the knob, and sometimes changing step after I have stopped turning the knob. Could either compressed air or DeOxit help? Or is it hopeless? - FARMERIK
