Paul:
IMHO the super-replacement DSP AM/SW/FM will be mechanically tuned without a digital display, having a standard Class AB speaker output.
Digital displays are creating shielding problems that are not/can not be solved. Take a R-911 and put the DSP chip in it, replacing a lot of hardware, keeping the audio amp for the speaker. Call it a D-911.

Jay this rings very true. I have recently looked at the specs of the newer SI chips, and they are showing a very stubby ferrite rod as being acceptable. Its about consumers: not enthusiasts.

Re: Degen DE1128 Info

Hi Gary:

Thank for your reply.

The radio is specified as a FM Stereo-MW-SW DSP receiver.

Orders may be made at website http://tecsunradio.com based in Kwangchow (Canton) China. Contact person is Erin via hch@cantonmade.com.

The complete package incl. international shipping is below US$95.00 and arrived in 2 weeks from date of order.

I must agreed with Jay it's a feature-rich radio with MP3 player and recording function built-in.

According to Degen, this product is milestone in 112X series but not to replace the DE1103 which they claimed to have sold over 300,000 units worldwide.

They also cited difficulties in getting components that may run out later for DE1103 and the software interface for design modern receiver like DE1128.

The limitation of MW could be due to the size of the radio to house the ferrite antenna as in DE1126. SW tuning is also limited at 5KHz internal covering from 13m to 120m unlike Tecsun PL210 with full band coverage from 522-29999KHz

As mentioned earlier, the outstanding feature of this handy product is it's connectivity with computer eanble MP3 songs and new podcasts to be downloaded directly and ready on the go...

The receiver is still its primary function but with many more features now!

Dear Mkang,

Thank you very much for posting the detailed information about the new
DE1128 receiver. It sounds very interesting.

Although the LCD language is not in English and the MW band tuning
steps are fixed at 9 kHz, if the new radio has FM sensitivity and
selectivity similar to (or superior to) the Tecsun Si4734 DSP chip
radios (PL-300WT, PL-310, PL-380 and PL-606), I would be very
interested in ordering a sample DE1128 to test out (if you can suggest
an ordering source in China or Hong Kong). Our Ultralight radio
enthusiast group has many FM-DXers, and they would probably be
interested in its performance compared to the Tecsun DSP models. A
translation sheet for the Chinese characters (to English) can be
probably be made up here, if the radio's FM-DXing performance is
excellent.

New radio + New Station

Dave Hascall
 

I received a new Tecsun PL606 on Wednesday.  I purchased it from ebay seller kaito-electronics-inc for $49 shipped, via a traditional auction.  Yup, I saved 99 cents over Buy It Now, :)  The seller ships from California and not China.  Paid last Friday, he shipped Monday and I received it Wednesday.  FAST!

Man this radio is sensitive!Man do I miss direct tuning!  Lol.  Yup, it has some quirks but the radio has good sensitivity.

In the ten minutes I listened, I managed to add a new one to the ULR book - WJLS 560 WV.  Not too bad a start.  Nothing on LW but that was expected, being barefoot.

I will work at learning its operation, such as trying to keep it in fast tuning mode, keeping the light on and so on.

Hi there:

The Chinese Degen DE1128 only support LCD language in Chinese (both traditional & simplified version) & Russia and MW is fixed on 9 KHz...

The radio is a multi-purpose device incorporating receiver, MP3 player, digital recorder and music box functions.

Accordingly to Chinese website, it is supposed to be a milestone product after DE1103. The interface is similar to DE1126 with an additional speaker and numeric keypad to allow direct frequency entry...

The receiver is optimised for FM stereo listening with RDS support. FM coverage from 64-108 MHz, MW from 522-1710 KHz. SW from 2.3 to 23 MHz. A microSD card slot is available for additional storage.

FM & SWBCL for major broadcasters are sufficient on this small radio with whip antenna only, though MW is barely adequate. Volume control from 0 to 31 level but no treble & bass functions unlike other DSP come with variable bandwith control.

The dual speaker system giving crisp and clear sound suitable for both indoor & outdoor hearing. Connectivity to computer for downloading of files and for lithium battery charging is a fast & easy.

This latest offering from Degen 112X smart-radio series is definitely a step ahead of other like the Tecsun PL398MP & Anjan DTS-13... especially with the computer-based control interface which allow user to change the setting at a touch of the button.

Re: FSL Antenna Design Optimization Article

Thanks for the reply Everett. Looks like you have likely cornered the market on those 62 mm Ferrite Bars, since I heard that Combat is out of them for now? Everett, you Gary and Kevin have made those Russian Ferrite sellers a pile of cash which is a probably good thing.  
 
Haven't had a chance to try out the Russian Varicaps on the 20 inch Diameter Cake Dummy FDL  mainly due to mounting problems re my PVC setup.  I'm wondering if the current 9 turns of 660/46 Litz wire  on that 20" Cake Dummy will give enough band coverage with the Russian Caps, but some experimenting will likely resolve that issue.  Might try mounting the Russian Varicap on the PVC elbow, also I think metric screws are available up here. That is encouraging news re its performance above 1000 kHz, so I hope to  try it out soon.

Hi Jerry,
 
Yes it is a aluminum plate that I drilled holes in to fit the Russian varicap. How I did it, is I take a piece of paper and cut a 1/2" hole in it, so it will slip over the varicap shaft and then I take a pencil and rub over the screw holes on the varicap. This is then a template that can be used to mark the aluminum plate for drilling.
The Russian varicap screw holes are metric, however, I re-tapped the holes to a US size. The varicap frame is made of a soft metal, so you can force it to take almost any screw that will fit in the hole, if you do not have a tap and die set.
 
Also Steve R recently did some Q testing on several Varicaps and he noted that on frequences above 1,000 KHz that the Russian Varicap was considerable better then the N-50.
 
What did you end up with band coverage after you added the Russian varicap to Cake Dummy FSL?

Everett, good informative writeup, how did you attach your Russian Varicaps to that wooden frame?  It looks like you used some sort of flat plate.

Hi Paul,
 
I looked at your drawing and with the spacing that you will have between the two coils you could wind them in the same direction, or in contra. With such a large separation between the coils and the ferrite, you will have two FSL's with one common varicap. I am sure it will work, I just don't know how well.
 
What I am finding in some of my most resent experiments is that the Pollydoroff design works much better then two coils wound in contra and it take a lot less wire.
 
 
In the Poloydoroff design the coils are wound in the same direction and the coils are connected in series. So on the 2 coil system the two outside wires are connected together and the two inside wires are connected to the varicap, on the 4 coil system the coils are treated like two pairs of coils, so each pair has it's outside wires connected together just like it is done on the 2 coil system and then one inside wire from each coil pair is connected together and then the two outer most wires are connected to the varicap.
 
I will be doing some more experimenting to see if a 3, or 4 coil, contra wound design is any better then the Polydoroff. But for sure the Polydoroff design is better then a single, or dual coil (wound in contra) FSL.
 
You can see answer to your questions below:

The Polydoroff design has proven to be much better than 2 coils wound in contra. Which I have copied you on my experiments.

I WOULD BE VERY INTERESTED TO KNOW IF IT IS BETTER BY THE SEPARATION DISTANCE

IE DOES THE MEAN DISTANCE BETWEEN THE CONTRA WINDINGS PRODUCE NOTABLE INCREASE IN DX PERFORMANCE.I don't know, however, more spacing does lower the distributed capacitance, which is a Q killer. It also reduces the inductance, thus requiring more coil turns, which I think is all good.
I HAVE MENTIONED TO GARY A DESIGN I AM PLAYING WITH HERE WITH THE YELLOW PAIL DESIGN (SEE PHOTOS SECTION) WHERE THERE IS 300 MM BETWEEN MEAN CENTRES OF THE CONTRA

SO YOUR COMMENT HERE IS INTERESTING FOR ME AS TO WHETHER WE INTREPRET LENGTH IN GARY'S NEW FORMULA OR NEED TO INTRODUCE AREA (OR EFFECTIVE AREA) It looks like there is a correlation between Gary's formula and tubular surface area based on the 3 examples that he had. However, I don't know it will be the same if it is scaled up to a larger size FSL's

AGAIN FOR NOW I AM INTERPRETING A POTENTIAL GAIN IN DX AS A FUNCITON OF WHAT I WOULD CALL EFFECTIVE FERRITE LENGTH EVEN THOUGH MAJORITY WOULD BE THE AIR GAP BETWEEN THE CONTRAS IN TERMS OF THE NEW FORMULA. Again I don't know. About 2 months ago I tried to make up a FSL with the wide spaces between the ferrite, but I could not get enough wire on each of the segments to reach the desired inductance, so I was never able to complete the project.

New one at sunrise 3/28/12

bbwrwy
 

It seemed that whenever Kirk Allen or myself couldn't hear anything new on the AM band around sunrise we would often tune from 900 to 930 kHz and hear something new. This morning, I once again tuned to 910 and there was a new station. So, Billy Bob this one is for you!

3/28/12
1217UT 910 KGME, Phoenix AZ (5 kW 1373 km / 853 mi), fair strength at peak. Ad. for attorneys Lerner and Rowe, Phoenix, at 1217, followed by "Fox Sports Daybreak"at 1218, and promo for "X-tra Sports 910" at 1229. Signal faded out under KVIS at 1233. Barefoot SRF-T615.receiver. New station #992 (barefoot #981).

With the K-Index elevated I expected only signals from the south this morning. But that wasn't the case as I was able to hear stations from every direction.

Buena DX.

Richard.

Two at sunrise this morning

Allen Willie
 

Hello To All,


Around sunrise this morning I heard the following:


1070 - WNCT - Greenville, North Carolina 8:50 UTC Mar 28
Oldies including "Lady Willpower" then into WNCT.com and ID
(Last heard April 9, a week after arriving at new location here)

1700 - KVNS - Brownsville, Texas 9:10 UTC Mar 28
"Dancing In the Moonlight" then into "Classic Hits 1700 KVNS ID)
(Strongest signal heard from this one ever)
lists as 880 watts nighttime


Receiver : SRF-M37V barefoot

Good DX

Hi Allen,

It's great to hear that you've started to DX from high elevation spots
overlooking the Atlantic Ocean.

Ultralight radios (and compact antennas, like the FSL and smaller air
core loops) are ideally suited to take advantage of the superior
transoceanic DX propagation at these ocean view spots-- and on the
Atlantic coast, you wouldn't even need to get up at a bizarre local
hour like 0300 to enjoy the best LW and MW propagation (like we need to
do here on the west coast :-) The 400' ocean view spot on the Oregon
coast provided some fairly exotic South Pacific DX catches for me last
year, and I hope that the same thing will happen for you with exotic European, African and Asian DX coming in at the Atlantic Ocean view
spot.

73, Gary DeBock (in Puyallup, WA, USA)

Hello To All,

Haven't checked in for a while so we thought we would update everyone
as to what's been happening lately here in the "Hope".

With the weather a bit warmer here lately we thought we would start
Dxing with the ULR's outside occasionally at a newly discovered spot
with a front row seat overlooking the Atlantic Ocean a bit further east
of our location. It is at a point much higher in elevation than our
home location ( about 400 feet above sea level)

With ULRs in hand and an approaching sunset time, an initial half hour
or so was spent this evening monitoring the band.

The two strongest signals were from Libya on 1251 and of course the
Saudi Arabia powerhouse on 1521 khz. Both extremely strong.

It will be interesting to DX from this location over the coming months
at sunrise and sunset times as well. More detailed reports to come

There is a newly uploaded photo of the view from that location in the
Ultralight photo section in the VO1001SWL folder.

Good DX
