Small indoor terminated loop antenna article now available

Kevin S <satya@...>
 

Hi all:

Living in a small townhouse with all of its restrictions on antennas, a
good EWE, Super Loop or other highly directional terminated antenna was
always just a dream, until I discovered that such antennas can be placed
indoors with good results. Just posted to DXer.ca and the Yahoo
UltralightDX group is an article which describes the construction and use
of a Super Loop that fits in my DX shack but has significantly increased
what I can hear, especially TA/TP reception. I closely compared Slinky
versus wire construction, the advantages and disadvantages of different
size loops, the effect of PVC construction, and how small terminated loops
stack up against commercially available active antennas. I also give a
very positive review of the new Wellbrook FLG-100, designed for terminated
loop use.

As more and more DXers find themselves in restricted quarters with little
room to work with, smaller antennas like these, whether used indoors or
outdoors, may be the best option available. In combination with the
remote termination unit that I posted a little bit ago, my DXing has taken
a definite step up, whether coupling the output to an Ultralight or
feeding it to a desktop communications receiver.

Here's the DXer.ca link:

Hmm. My new PL-380 from ANON-Co, s/n 36920091000223, dated 11/2009 has two screws. Don't know if it's relevant, but FWIW.

I was leaning towards the 310 but now see there may be an upgraded PL-380. Any thoughts on waiting for the newer 380


Re: 7.5" Loopstick PL-380 vs Stock PL-380... Daytime DX Sh...

Gary DeBock
 

Hi Jim,
 
Thanks for your comments.
 
The RSSI and S/N ratio readings were averaged out in each case, since the PL-380 repeatedly samples the readings every few seconds.
 
The "00" S/N readings for several weak fringe stations did not give an accurate measurement of the relative reception capabilities of the two radios. In cases where both radios showed a "00" S/N ratio reading, the volume on each radio was raised to maximum, and a judgement was made on the signal quality. As the table indicates, on several fringe stations the modified PL-380 actually had fairly good reception, despite the "00" S/N reading. On the same stations, the stock PL-380 had no reception at all. Apparently the S/N reading from the PL-380 display is not a very accurate indicator of actual signal quality, at least as far as weak fringe stations is concerned.
 
73, Gary

It's interesting (to me, anyway) that in six out of eight, the signal level increased by 13-22 dB, but the S+N/N ratio did not improve. The increased ratio on 1110-KWDB is significant, >20 dB. The ratio between signal and noise is what ultimately makes it possible to hear a station. If the noise level increases as much as the signal, there is no net improvement in readability.

Intuition leads one to think a resonant, high-Q antenna would improve S+N/N ratio more uniformly. These numbers imply that 75% of the stations could be heard as well on a stock radio, simply by turning up the volume control. The huge difference on 1110-KWDB is inexplicable.

New article on terminated loop remote resistance control

Kevin S <satya@...>
 

Hi all:

For those of you using or looking at a EWE, Super Loop, Pennant or other
terminated loop antenna, just posted to DXer.ca and the Yahoo UltralightDX
group is an article about a controller which precisely varies the
resistance over a selected range. In experimenting with a Conti Super
Loop, I have found that a single resistance value will not provide
acceptable nulls for the entire band (the optimum value can vary by
several hundred ohms depending on the target), and that the ability to
fine-tune the resistance can make a big difference, since being off by
50-75 ohms might miss the null altogether. This remote termination design
allows you to stay in front of the radio while you tweak the resistance
for the best null. Thanks to Steve Ratzlaff for the bulk of the design
and construction!

Re: G8 vs CR-1100 preliminary AM BCB report-FARMERIK

Gary DeBock
 

Hello Richard,
 
Yes, you are absolutely correct.
 
The radio is the new Redsun RP007, a waterproofed, shock-resistant AM-FM-SW portable radio apparently designed by Redsun according to a demanding order by the Russian military. The radio is specifically designed to withstand severe weather conditions, so that a special agent out in the field could receive radio communication despite rain, severe cold, or even dropping the radio in a river (!).
 
The original plan was to report to the group about the awesome survival capabilities of this new portable radio (which actually has very good AM reception, similar to an RP2100 with better IF filtering), but for some reason Redsun never found a seller to market the radio on eBay for export (the Chinese domestic price is around $140 on Taobao), so until an eBay seller offers the model for sale, I don't have any source to recommend to potential purchasers. To make this story even more bizarre, the anonymous eBay seller who sent me this free radio (which he received free from Redsun) is now no longer selling on eBay, having gone through a stretch of poor health, which caused delayed radio shipments to send his feedback rating from 100% down to 97%.
 
The entire episode is like something straight out of a spy thriller. So my free Redsun RP007 (despite its awesome survival construction) now still awaits a purchasing source for North American hobbyists, before I can post a full review on it.

Hello Farmerik,
 
All of the radios you mentioned (G8, PL-380, CR-1110 and PL-600) are on hand here, in this overcrowded shack.
 
The CR-1110 is a rather odd bird that has far better AM sensitivity on the high frequencies (especially the X band) than on the middle and low band. It was tested extensively against an aligned Sony ICF-S5W on all frequencies from 530-1700 kHz, and was found inferior in sensitivity to that classic model on most AM frequencies, but clearly superior on the X band. It also did not suffer from the ICF-S5W's severe image reception issue, of course.
 
I did a mini-review of the CR-1100 back in June, which may be of interest to you. Some of the information is dated (such as the praise of the PL-300WT, the only DSP model available at the time), but the rest should give you detailed impressions on the model. Hope you enjoy it!
 
73 and Have Fun,  Gary  
Hello All,

Very impressed with the performance of the new Tecsun PL-300WT DSP-enhanced
 Ultralight radio on medium-wave, it was a natural decision to place an
order  with Amazon.com for the new full-sized Tecsun CR-1100 AM-FM portable,
which uses  the same innovative Si430/31 DSP chip from Silicon Labs. Today my
new  CR-1100 portable arrived from Kaito Electronics after a 4-day delay,
and payment  of $69.99 plus $13.00 shipping (by USPS Priority Mail).

The CR-1100 is strictly a Chinese-market portable, to the extent that all
of the controls are labeled only in Chinese. Despite this, Kaito has
provided a  very basic (and poorly translated) English manual, as well as the
standard and  far more thorough Chinese manual. The AM frequency steps have also
been  reprogrammed to 10 kHz, matching the North American market.

Immediately after arrival, the radio's out-of-the-box AM performance was
tested against a fully aligned Sony ICF-S5W portable (which has had the
frequency coverage extended to 1700 kHz). The comparison of these two radios
proved to be very interesting, and showed that while the CR-1100 has  some
good DXing potential on AM, it also has some puzzling  shortcomings.

In comparison to the PL-300WT's sharp DSP-enhanced selectivity, the CR-1100
 had a tough time going up against the ICF-S5W, with its common 455 kHz
Murata filter.  Local slop on the CR-1100 was more troublesome than on the
PL-300WT, making it seem like Tecsun programmed the DSP chip to provide a
wider  selectivity setting on this music-oriented receiver. The ICF-S5W was able
to  weakly receive KPQ-560 in the null of semi-local KVI-570 in the early
afternoon,  while the CR-1100 could only produce KVI splatter. Low-band
sensitivity on the  CR-1100 was very good, but not quite up to the class-leading
ICF-S5W  standard. Although the CR-1100's low-band sensitivity will match
that of  the PL-300WT, unlike the PL-300WT, the CR-1100 cannot tune in 1 kHz
steps,  making it impossible to chase TP's on the 9 kHz splits.

The CR-1100 versus ICF-S5W contest became much more competitive on the high
 band, however, and on the X-band the new Tecsun was clearly far more
sensitive than the classic Sony portable. In fact, the CR-1100 sets a new
standard for X-band sensitivity among portables, having weak signal performance
never experienced in extensive testing here. Weak fringe stations that were
barely audible on the ICF-S5W had solid audio on the Tecsun.

Also notable in the CR-1100 was the complete freedom from image reception
of local stations, a major shortcoming of the classic ICF-S5W. The Sony's
image  reception detracts greatly from its otherwise stellar performance, but
the  Tecsun DSP chip appears to have solved the problem entirely.

After the out-of-the-box performance test, the CR-1100 was disassembled to
check the loopstick construction, and the possibility of alignment. Both
the  PL-300WT and CR-1100 were designed to have a "no alignment" RF system, in 
which  the DSP chip ensures maximum performance without loopstick peaking,
or  adjustment of a 1400 kHz trimmer. In the CR-1100, there is a 4.25" x 
.36"  single-coil loopstick in the middle of the cabinet, which seems rather
odd  because of the extensive cabinet space on both sides which would allow
placement of a much longer ferrite bar, if desired. Alignment was attempted
by shifting the coil, but this had no effect on the CR-1100's sensitivity on
any  AM frequency. Apparently DXers will need to accept the CR-1100's
sensitivity as delivered, unless they wish to transplant a larger ferrite bar
with a coil of equal inductance (which is certainly possible with all the
extra  cabinet space).

The CR-1100 also has a sensitive FM section, although again, for some
unknown reason it seemed slightly less sensitive than that of the PL-300WT.
Perhaps there is a greater impedance mismatch with the CR-1100's short whip
antenna, but in any case the PL-300WT Ultralight can receive more weak FM
fringe  stations here than the CR-1100.

The CR-1100 has a large music-oriented speaker and excellent audio,  with
analog tone and volume control knobs. The 8-ohm speaker has a 1-watt  rated
output. The radio also has 300 memories, and various digital tuning
capabilities. It operates on 4 "D" batteries, and comes in an attractive
black-brown cabinet. It is available from Amazon.com (via Kaito  Electronics) for
$69.99 plus $13.00 shipping.

So after the full evaluation, what would be the CR-1100 verdict for a
dedicated medium-wave DXer? If you are a domestic DXer that concentrates on  the
upper frequencies (especially the X-Band), the new CR-1100 would be  tough
to beat. Its upper-band sensitivity (and generally good  selectivity) is
likely to set a new standard for contemporary portables. Urban  DXers will
appreciate the complete freedom from image reception, and general  freedom from
spurious products. Hobbyists who enjoy music reception will not be
disappointed in the CR-1100's audio qualities. However, if you wish to  chase
transoceanic DX, or wish to experience the maximum potential of the  exciting new
Silicon Labs DSP chip, my recommendation would be to pass on the  CR-1100--
and go for the new PL-300WT Ultralight model. Its 1 kHz tuning ability  and
stellar selectivity (plus superior FM sensitivity) make it the obvious
choice for most medium-wave DXers.

73 and Best Wishes,

Gary DeBock (in Puyallup, WA)



 
 
OK, now I get it. Sort of like the audio version of the screen break-up on digital video. I can see why it would be a problem for really weak signal DXing, however on my G8 I don't think I will miss any station strong enough to actually listen to.
Both the G8 and CR-1100 hear weak stations with less noise and interference than my analog radios, but miss all the really weak signals entirely. The CR-1100 is significantly more sensitive and has less noise on its weak stations though. Anyone have a PL-380 AND a CR-1100 to compare? My new PL-600 seems MUCH more sensitive than the CR-1100. - FARMERIK

I tuned three ten 'channel' bands, 700-790, 1000-1090 and 1500-1590, and took notes on each station I heard. I'll summarize here. The CR is noticeably better on about 50% of the frequencies, and about 1/3rd of those are substantial improvements. I got stations on all but 6 of the 30 frequencies on both radios, so it is a good night here in Connecticut.

7.5" Loopstick PL-380 vs Stock PL-380... Daytime DX Shootout

Gary DeBock
 

Hello All,
 
Thanks very much to Nick for posting the detailed observations on his PL-380 loopstick experiments. His measurements of coil "Q" for different loopstick configurations is especially appreciated, and will be useful in creating new loopsticks for the PL-310 model.
 
 Continuing the testing of the newly modified PL-380 model with the 7.5" external loopstick (described in an article posted on the Ultralightdx file site, and on dxer.ca (as well as directly linked at  http://www.mediafire.com/?jjcvkzxnztj ), further testing of relative daytime DXing capabilities was conducted yesterday around local noon.
 
The following table details the RSSI readings (in dBu) and S/N readings (in dB) received on both units while receiving various fringe stations here in Puyallup, WA during these daytime DX conditions
 
 
                              Stock PL-380                          External Loopstick PL-380
 
 
530-TIS                    18 dBu, 12 dB                               40 dBu, 18 dB
610-KONA                17 dBu, 00 dB (no reception)          30 dBu, 03 dB (fair reception)
750-KXL                   29 dBu, 00 dB (weak reception)      42 dBu, 00 dB (moderate reception)
1110-KWDB             30 dBu, 00 dB (trace)                     37 dBu, 21 dB (moderate reception)
KJOX-1390               34 dBu, 00 dB (no reception)          49 dBu, 00 dB (weak reception)
1510-KGA                29 dBu, 00 dB (no reception)          43 dBu, 00 dB (weak reception)
1600-KVRI/KOHI       17 dBu, 00 dB (no reception)          35 dBu, 00 dB (weak reception)
1640-KDZR               19 dBu, 00 dB (no reception)          39 dBu, 00 dB (weak reception)
 
As posted earlier, this 7.5" loopstick PL-380 also provided good reception of two TP stations as a stand-alone receiver here early this morning, with 972-HLCA and 738-Taiwan having decent signals around 0900 UTC during the Asian sunset period.
 
73 and Good DX,

HI Guys:

I'm camped out on 101.9 Mhz and I'm hearing the odd Meteor Scatter
ping today!! Nothing long or ID'able yet.....but it's Pinging away!!
I'll leave the FM Tuner on 101.9 all day and see if anything makes it thru!!

It MAY be possible to hear some MS DX on your ULR on FM if you have a Nice QUIET OPEN Frequency!!

Booming Night Owl TP's on the 7.5" Loopstick Tecsun PL-380

Gary DeBock
 

Hello All,
 
Thanks to Nick, Nigel and Bill for their sunrise TP reports this morning.
 
Having also experienced the recent mediocre strength of the TP's during our west coast sunrise period, I've occasionally checked the propagation to Asia around 0900 UTC, during the Asian sunset period. Although the west coast hour is far from convenient (0100 local), this early morning the Asiatic TP's were really strong on the newly modified Tecsun PL-380 DSP receiver-- with many having the best signals heard for over a month.
 
Although the $45 Tecsun model has no "S" meter, HLCA-972 was like a solid "9" on the stand-alone modified PL-380 at 0906 UTC, with this vibrant signal from the Korean YL announcer:
 
 
Tuning around and checking the other Asiatic signals (while the more sensible west coast DXers were sleeping), I found equally strong Japanese signals from 594-JOAK, 747-JOIB and 774-JOUB. 1134 kHz also had a nice mix of JOQR and the KBS Korean, while 657-Pyongyang had some serious strength behind its YL's tirade. Finally I checked 738 kHz, hoping to find a nice signal from the KBS Korean, but instead it was all Taiwan Fisheries with their Chinese call-in program, having this fairly good signal on the modified PL-380 around 0926: 
 
 
Because of their freedom from the "soft mute" issue affecting other DSP radio models, the modified PL-380 (and barefoot PL-380's) can tune 1 kHz farther away from domestic splatter to improve reception, and to eliminate heterodynes with domestic stations. This was done with the modified PL-380 during both of the above recordings, so that the 972-HLCA recording was actually made on 973 kHz, and the 738-Taiwan recording was made on 737 kHz. This trick eliminated the 2 kHz heterodynes, and helped the DX stations escape domestic splatter.

Scott,

It looks like Keith may be right on the money about the station you've been hearing. Although I couldn't find a date associated with this info, here's what I just ran across on the Texas Music Office website @ http://governor.state.tx.us/music/directory/radio/radio.panhandle/

"KIKZ-AM 1250
Owner: Gaines County Broadcasting, LLC.
105 Northwest 11th Street; Seminole, TX 79360
(432) 758-5878; (432) 758-5878; Fax (432) 758-5474
kikz-ksem[at]SPAMAWAYmywdo.com
Country, Tejano
KIKZ (1250 AM) is a 1,000-watt country, German and Spanish language music station. We are community oriented providing local news and sports."

Hope this helps a little.

Scott,

I don't know the answer, but two possibilities occur to me:

Number one, your c & w station may be undergoing a format change. Sometimes when stations are in the process of flipping formats, e.g. from country to oldies, they may play a lot of songs in a row, with few or no voice announcements, maybe just a brief, five or ten second recorded station i.d. at the top of each hour. This can go on for hours, even several days.

Number two, sometimes stations are "brokered," that is, instead of having commercials, they sell blocks of air time to basically anybody who wants to go on the air and can afford the time. This is similar to the infomercials you see on TV for the Snuggie, Sham-Wow, etc. There's a station in my market, Seattle, KKNW, "Alternative Talk 1150", that does this. Programming can be radically different from one hour of the day to the next. I've heard programs on astrology, followed by Christian religious programming, following by Russian language programming, followed by high-school sports, all in the same day on the same station!

Regards,
Keith

Hey everybody!

Thanks for the wonderful welcome, but I've got a problem
here. Today, at about 1330 MST, I was band-scanning on MW
and came upon something extremely odd. Instead of country
music, which is what 1250 KIKZ (Seminole, TX) usually plays,
I heard Regional Mexican music. Then, it faded out. Then, I
heard someone speak in wha sounded like Arabic. Then, the
language changed to German-sounding. There was a song or two
played along the way, one in Spanish, and another in
English, before the transition into the weird languages (no
music, just straight talking). And, during the whole of
about 45 minutes of listening, not a single discernable
station ID. Someone help! I gotta figure this one out so I
can get it logged!

Thanks!

From Mexico to Canada

Kirk <kirk74601@...>
 

I was able to scrounge up a few new stations overnight, the first ones for the new decade. I parked on 1410 and 1420 for long time both this morning and Fri morning trying to nail IDs from previously UNID stations. Persistence paid off because these definitely didn't just fall in my lap, hi hi.
Logged on SRF-59 w/ SAT.

1410, KGSO, Wichita, KS, 0740-0800+ UTC, 1/3/10, It took 2 evenings to pry an ID out of this one. Hrd w/ sport stalk, some net ads then ID @ the TOH. Fox Sports affiliate. Mixing w/ some XE's as well as another sports sta (ESPN) which is still UNID here.

1420, XEF, Ciu. Juarez, CH, 1108-1233 UTC, extremely difficult to follow the pgm'g on stations occupying this freq. XEH, Monterrey, is a huge problem for logging other stations here. Hrd this one w/ mx & talk by M ancr. Canned IDs possibly were "Linea Deportiva Chihuahua." Also noted the call ltrs @ 1126. VP copy. -LAm #150-

1420, XEEW, Matamoros, Tamaulipas, 1108-1233 UTC, 1/3/10, Best I could tell, this sta was all tlk. Hrd many Grupo Formula IDs. "Grupo Formula W" IDs confirmed this one. VP copy. Not sure, but I think XEXX was also audible.

800, CKLW, Windsor, ON, 1243-1301 UTC, 1/3/10, nice sig peaks @ t/in and also near the TOH. Paid programming was hrd. "Be one of the first thousand to call...." ID was "AM 800, CKLW" @ 1259. Current temp was -17 C. -ULR Sta #370-

73 for now,

THANKS! I never thought of checking Wikipedia. Every once in a while I receive a station strongly in what I would expect to be the Null. A mystery to me, but so are a lot of other things. - FARMERIK
