Hello To All,


Propagation for the most part has been very good here in the Hope for the past few early mornings and evenings. Noted was an excellent opening from the south early Tuesday morning with a good number of Cuban stations logged.

Radio Paradise from St. Kitts was sounding like a local for a while as well.

Sony SRF-S86 ===audiophile upgrades

Joseph Fan
 

All,

Just got around to opening up my Sony SRF-S86 to upgrade two output caps and one power cap as noted by Xin and wanted to note a few items:

1. The SRF-S86 FM band runs 76-108 and might be a current 2011 Japan exclusive model

2. The SRF-S86 board has been slightly reworked (or just reprinted) compared to the SRF-S83 Xin documented

2.a. a few apparently minor changes (different white printed numbers on the board and a tweak to at least the transparent cover of the large "tuning box")

2.b. the white printed circles around the one 220uf cap and three 100uf caps are now the same size as their respective caps:

==> not so obvious that these should be upgraded to 330uf and 220uf, respectively

==> given the SRF-S86 still has the lousy bass boost switch and board looks essentially similar, I still bet the output caps should be upgraded. The power cap upgrade is a no-brainer

2.c. Just below the 220uf cap, sits a small cap seems to have been downgraded in the SRF-S86 to a 22uf cap
==>what is the purpose of this cap?
==>what was it previously rated at?

TECH: MW dual coil ferrite rod tests, contra vs. non-contra

Steve Ratzlaff <steveratz@...>
 

I tested a dual coil contra-wound compared with a dual coil non-contra wound MW ferrite rod setup, using two Amidon -61 7.5" rods and two PL-380's today just before noon. Results show both are about identical with perhaps a slight edge to the non-contra over the whole range.

non-contra contra
610 kHz 45/25 43/25 (signal strength/RSSI)
810 kHz 32/25 31/25
1060 kHz 30/25 29/23
1080 kHz 17/06 15/05
1250 kHz 30/25 30/25
1360 kHz 24/21 24/20
1400 kHz 22/18 20/16
1420 kHz 36/25 34/25
1430 kHz 22/03 19/02
1510 kHz 25/24 25/23
1610 kHz 23/24 22/23

(Last night on 1700 kHz with the California sports station, both were reading 52/25 on peaks.)

Both coils were 50 turns 40/44 Litz with a small spacing between them, with the coils near the center of the rod. The DM4070 LCR meter was used to set each coil close to 580 uH than taped in place on the rod. With both coils in parallel, that gives about 420 uH; in series, about 1700 uH. The coils were used in parallel for the MW check. As noted before, use of dual coils seems to give somewhat better sensitivity for weak signals than a single coil.

Re: Two New ULR Logs This Afternoon- the hard way

John Cereghin <jcereghin@...>
 

I was able to ID my unidentified TIS station I reported last night on 1630:

1630 WPVT502. Avalon NJ, mentions of www.avalonbeach.org and many
mentions of Avalon, heard in Camden DE at lunch in a swampy area, not
really heard elsewhere in the Dover-Smyrna area. The salty water
helped the groundwave.

The South Jersey TIS stations have been in well lately, making it
across the Delaware Bay at about 40-60 miles. Heard on the PL-310.

And I had my ULR totals wrong- I'm now at 797 stations.

Had another TIS station on 1630 but was way too weak to make out.

Both stations heard about 40 miles away, I have to work out the distances.

Now at 794 ULR stations.

TECH: contra coil vs. non-contra coil Q tests

Steve Ratzlaff <steveratz@...>
 

Since the xtal set DX world likes the contra-wound dual coil arrangement, and since my own ferrite rod dual coil experiment did not use contra-wound, I did some air coil tests today with the HP4342A Q meter, comparing the two winding techniques. I used the standard styrene 4.5" diameter form that the xtal set DXers use to make extremely high Q solenoid coils (with 660/46 Litz), and wound two pairs of coils, one contra-wound and one non-contra wound, using a separate form for each pair; 25 turns for each coil using 75/44 Litz that I have a large spool of. Q for the various configurations should be substantially higher if one type of winding is superior to the other. (Q, or "quality" of a coil is a dimensionless quality, with higher Q at a given frequency being better. The sytrene solenoid mentioned wound with 660/46 Litz can give in excess of 1500 Q at MW mid-band frequencies. For the xtal set builder this directly translates to narrower bandwidth, which is desirable to better separate AMBC stations. Since Q decreases with frequency, as high a Q as possible at the upper part of the band is desirable.)

A good discussion of actual method of winding the contra coil is given by Dave Schmarder http://makearadio.com/coils/contracoils.php . (Thanks to the several folks who emailed me that link.) I used his cylinder coil example except I used 25 turns for each coil instead of the 22 turns he used. He also used higher-count Litz than I did, but that should affect only the Q readings, which should be higher with the 165/46 Litz he used. He gives some results using his homebrew non-Q meter method of Q measurement, and tested at 600, 1000 and 1600 kHz. I used the same frequencies for my tests--his results are different (lower Q) from what I obtained for my 75/44 Litz using the HP4342A Q meter.

Results:
Non-contra wound coil
First coil 128.4 uH, 311 pF to resonate at 798 kHz, Q 451 at 798 kHz
Second coil 130 uH, 308 pF, Q 450

Parallel coils 1600 kHz 91.5 uH, 98.5 pF, Q 605 (poorer than contra)
Series coils 1000 kHz 371 uH, 67 pF, Q 660 (better than contra); 600 kHz 198 pF, Q 515 (better than contra)

Contra-wound coil
First coil 129 uH, 310 pF to resonate at 798 kHz, Q 448
Second coil 129.5 uH, 308 pF, Q 441

Parallel coils 1600 kHz 91 uH, 101 pF, Q 665 (better than non-contra)
Series coils 1000 kHz 378 uH, 64 pF, Q 603 (poorer than non-contra); 600 kHz 195 pF, Q 480 (poorer than non-contra)

Overall I don't see a large difference between the two winding methods.
For dual coils on a ferrite rod, the same general findings should apply except Q will be lower--take your pick of non-contra or contra winding depending if you want the high end emphasized (contra) or the middle/low end (non-contra).

I've also done some MW comparisons with a single coil compared to a dual coil using 40/44 Litz on the 7.5" Amidon -61 rod, with the PL-380. Signal strength/RSSI readings are similar for both on stronger signals, but weaker signals appear to be noticeably better both in strength and s/n ratio with the dual coil. Other folks should repeat these tests for themselves and report what they find.

Re: signal boost from unlikely sources.

Jay <jaypolicow@...>
 

Eb,

No surprise at all. What you have is a large grounded antenna. For portable AM radios with no antenna connections, one good way to couple to an external antenna is to bring the antenna near the radio (wrap it around it if it's a wire) then ground the near end of the wire. I discovered this as a kid quite by accident when I leaned my portable radio against the old BX metal-cald wire coming up from the ground to feed power to a garage. The metal covered wire was the antenna, it was grounded and the signal increase was huge.

After installing 2 new batteries(I always carry some AA's to such

around the store to find better reception,I noticed an increase in
volume and found myself next to one of several large steel arches
supporting the building.Orienting the radio closer to this beam,
volume increased to comfortable listening levels.
As I had heard about such phenomena previously,it occurred to me
that my 36 foot tv tower could do the same.I used the KGO signal
for level comparison with a PL-380.
Here are my readings:stock loop 30/25, 350Uh/7.5 #61 rod 50/25,
PL-380 with stock loop placed into a U-shaped section of the
towers ground cable 50/25,the strongest I could find at various
spots around the base.This even though the tower is bolted
to the hardware in the concrete base.I admit,the tower is neither
ultralight nor portable,but similar placements may be possible in
other locations.I strongly advise against use of utility poles
and other hazardous locations,always heed NO TRESPASSING signs.

I would venture to suggest caution before letting the telescopic
antenna touch any metal - just in case there is a jolt to the
frontend of the radio, especially if without adequate diode protection...
An odd length of wire and crocodile clip or a loose capacitive wrap over
the telescopic aerial would be safer.

Re: Kchibo KK912T and KK-9803- DSP or not really? - FARMERIK

ferrite61 <dxrx@...>
 

I very highly doubt these two receivers has DSP. It is not printed on the radio itself, and the specs are horrible for even a R911/R9012 set. Also Kchibo's with the DSP had model #s that began with a *D* like the D92L or D96L.

Caveat Emptor on these two.

I don't know, but at those prices, it's hard to believe they could really have DSP, unless Kchibo has figured out a way to produce a DSP-equipped receiver at much lower cost than we've seen up till now. More likely they are comparable to the Tecsun R-911, R-9012 class of receivers.
 
On the other hand, they're cheap enough that it wouldn't be that much of a financial risk to order a couple to try out ;-).

In my watching for the new TECSUN PL-2010 DSP analog, I noticed these Kchibo radios advertised as DSP. Does anyone know if they really use a DSP radio chip, or just have a DSP audio circuit?

Both are sold by one Ebay store, deskfi.

Here is the auction number for one.-

Rik-
 
I don't know, but at those prices, it's hard to believe they could really have DSP, unless Kchibo has figured out a way to produce a DSP-equipped receiver at much lower cost than we've seen up till now. More likely they are comparable to the Tecsun R-911, R-9012 class of receivers.
 
On the other hand, they're cheap enough that it wouldn't be that much of a financial risk to order a couple to try out ;-).

Two New ULR Logs This Afternoon- the hard way

John Cereghin <jcereghin@...>
 

Lunchtime DX today with very good X-Band conditions brought two TIS
stations across Delaware Bay on the PL-310:

1670 1230 WMBQ847, Stone Harbor NJ, TIS info, mentions of Stone
Harbor, heard in Camden
1640 1235 WQGS571,North Wildwood NJ, TIS, heard in Camden, mentions of
North Wildwood

Had another TIS station on 1630 but was way too weak to make out.

Both stations heard about 40 miles away, I have to work out the distances.

Now at 794 ULR stations.
