Date   

Phillipines to Ireland on an UL!

Paul Logan
 

Hi all,

have been out of the UL loop recently but had one logging yesterday which made me very very happy and got my interest going again.

VOA Poro Point, Luzon, Phillipines, 1170, 1635 UTC om in special English talk about Pakistan / Afghan politics - fair peak, distance: 6658 miles / 10715 km

I first logged this a few days back on my regular set up ( even that was a shock) and wondered could I manage it with the barefoot SRF 39FP. After about twenty minutes of listening around sunset the English local Magic 1170 went into a deep fade revealing VOA in the clear.

It was a really thrilling moment. Almost makes me ashamed of playing with bigger radios!.

Paul Logan,
Lisnaskea, N. Ireland

Re: Anybody know a quiet mid-atlantic area?

Claudio Leite
 

Thanks, folks. Looks like the eastern shore of MD is the place to go.
I'll take a trip to Assateague Island State Park on Sunday. The MW scan
map is totally blank for a pretty big radius. The website says it's open
year-round and you can park by the beach.

I'll report whatever my results are.

The only major downside I can see is that you still have Philadelphia,
NY and Boston near or at the same angles as most of Europe, from a quick
look at a great-circle map. But at least no close-by BCB transmitters.

And wow--Kevin, that map makes me amazed that I've managed to DX from my
home location.

Thanks again.

Hi Claudio:

You can have it plot all of the known MW stations and see where the

(around Salisbury) and the piece of Viginia just south of that on the
peninsula are about the sparsest. If you're going south of that, Stumpy
Point, NC looks like an RF-desolate place.

I've copied the screen image and sent it to your email address, so
hopefully you'll get it.

Try http://fmscan.org/form.php?r=m&m=m&ex=1 , and enter the

would like to DX from, Claudio. If the link doesn't work, go to
http://fmscan.org/, then go to: maps, expert mode, AM, and the same
page will appear. A lot of good stuff on that site, though I wouldn't
swear to it having NRC log accuracy.

Good luck.

I didn't make note in my log, but KWAM 990, Memphis TN, was heard
between 1400 and 1500 UTC. Also there was a weak het on 594 kHz
around sunrise (1337 GMT).

Overall it was a good night for DXing. I spent too much time
listening to 940 kHz trying to hear CINW, Montreal. I would like to
log Quebec and that appears to be my best bet.

It's suppose to turn very cold here tomorrow morning. So, that means
I have no excuse to wander far away from my little ULR's. Best wishes
for a good DXing weekend to all.

Timed Recordings With an Ultralight

John H. Bryant <bjohnorcas@...>
 

I'll be putting together a little report on doing timed recordings from an Ultralight.  As I mentioned previously, I've wanted to apply the techniques that many GY DXers use to general hands-off DXing with an Ultralight. The general idea is to set the radio and antenna combination up on a specific frequency, with nulling, etc. set for an interesting direction and then leave the radio on all night. You connect the audio of the radio to a computer (laptop in my case) and use one of the software audio recorders that can be programmed to record periodically to  record TOH audio from the radio.

With Ultralights... unless you own a LOT of batteries, you need to supply a DC source to the radio, since it may run 24/7. The Eton e100 that I use has an input port for 3 vDC and Eton sells an aftermarket wall wart sized appropriately.  I was unable to find the specs of that little power brick, so I've ordered one to test.  In the meantime, I've been feeding the E100 with regulated 3.0 VDC from a regulated bench power supply.  I wound the feed line through a ferrite torroid 8 or 9 times as a noise choke, just to be cautious and I've not been able to detect any noise induced in the radio by running on "mains power."

I connected the headphone jack of the e100 to the microphone jack of the laptop with an audio cord that also had a ferrite noise choke. Since there is an impedance mismatch, setting the recording level and the volume of the receiver audio takes some care, but is easily accomplished. I use High Criteria's Total Recorder software. It is one of the two most popular amongst the GYers, I believe The other is ReCall Pro.  either recorder is easy to program for timed recordings and works like a charm.  I record from xx:58 before TOH until xx:08, well after any five-minute news plus commercials is over.

I'm using the Slider E100 with an outside antenna, so having the E100 close to the laptop is not a problem.  I think that this same strategy could work well with the Ultralight and the computer separated by a long audio cord (10'?  25'?)

I've got Total Recorder set so that it automatically titles each recording with the date and time of the recording, so I just have to know what frequency the radio was tuned to.  It takes me about 20 minutes to go through a complete over-night TOH recording and, so far, I've been getting one or, usually, two new stations each night.  I find it particularly interesting to watch the mix of stations change as the night passes from sunset through evening to very late night and then to dawn and post-dawn. Its often quite a parade.

As one of the older mossbacks in this hobby, I share the mossback concern as to whether this remote recording strategy is "really DXing at all," and I avoided it for years for that reason.  Last year, though, when I got involved with Graveyarding, I quickly concluded that it was really the only way to DX GY and maintain any sanity at all; after I began the remote recording, I found that I quite liked it.

In any case, once I have the data on the e100 wall wart and give a try to remote recording a Barefoot unit with a long audio cable, I'll do a more formal report...  If you are curious and have a bit of time over the Holidays, you might give remote recording a try!

I hope each of you and yours are enjoying this Holiday Season and are not too trapped by the weather!

ULTRALIGHT DX.......3 NEW STATIONS!!

robert ross
 

Hi Guys:

Well...it looks like a good few Days to stay holed up in the house and
do some Serious ULR DX'ing!!!! We are smack dab in the middle of a MAJOR
SNOWSTORM as is a large part of the Mid West and Great Lakes Area!! She's
howling pretty good out there right now with High Winds and LOTS of SNOW!!
This is a real Weird storm as the SNOW is coming outta the West....but the
Winds are outta the EAST.....and any storm we ever get from the east is
bizarre!! I filled the Gas Tank on the Snow Blower this morning....and
later tonight when this is all over (Hopefully)...we'll go out and ride it
around for a few hours!!

I did a little DXing in Mid afternoon yesterday..and again late last night
and this morning...and was able to find 3 More NEW STATIONS for the ULR
Log......One of which is also NEW to the OVERALL LOG as well.
I was surprised to hear SASKATCHEWAN on 620 Khz last night!!

Also another GRAVEYARDER for GY # 42 on Ultralight Radio!!

Radio used for this DX was.........SONY SRF-T615 with 2 1/2 Foot Homebrew
Tuneable Box Loop.

ULR LOG TOTALS are now.......................582 Stations heard.

Hello John,
 
     You have some excellent ideas for chasing GY stations, especially for those of us with no chance to spend long hours at the dial.
 
     Maybe the time has come for the final experimental frontier--  the "SDU" (Software Defined Ultralight :>)

Re: 7.5" Slider Loopstick DT-200VX Created-- Equals Slider E100's in Sensitivity

John H. Bryant <bjohnorcas@...>
 

Great Going on the DT-200VX Slider, Gary!  That is our first multi-coil unit... we both sure thought that it would work, but KNOWING is a different matter, eh?

After you finish the shootout and its report, possibly you can do a page or two-long report on the new Slider, with coil turns count, etc.... I suspect that there will be several folks owning either DT unit who could use a major boost in sensitivity.

John B.

Hello Guys,
 
     In preparation for making an ultra-sensitive Sangean DT-400W model, an experimental loopstick consisting of a movable coil of 40/44 Litz wire was wound on an Amidon type 61 7.5" ferrite bar, and transplanted into a Sangean DT-200VX model (which has the same loopstick as the DT-400W).  The result was another ultra-sensitive radio, with weak-signal capability exceeding that of the stock ICF-2010 and E1, and equal to that of the new Slider E100's.
 
     The DT-200VX/ DT-400W stock coil system consists of a base coil of .196 microhenry inductance (at the 600 kHz peak position on the ferrite bar), and a smaller "piggybacked" coil of .016 microhenries.  The piggybacked coil is wound on the side of the base coil closest to the center position of the ferrite bar.
 
     Initial tests at night revealed equal sensitivity with the new Slider E100 radios, which have become very popular among the Ultralight enthusiast group.  Two weak nighttime signals were used to check this-- the Yakima TIS on 1610 kHz, and the INE beacon on 521 kHz.
 
     Despite the supremely high sensitivity, the Slider DT-200VX lacks the relative signal strength bar graph of the E100, making the coil peaking strictly an audio judgement task.  It also lacks the E100's ability to tune in 1 kHz increments, making it unlikely to compete with the new Slider E100's in popularity among transoceanic DXers.  As might be expected, the selectivity with the stock IF filter is also a shade less favorable than the Slider-only E100, matching the relative selectivity performance of the stock models.  However, for those with dreams of making their Sangean DT-200VX or DT-400W models ultra-sensitive for supreme weak signal DXing, the new Slider DT-200VX is an exciting reality.

Re: 7.5" Slider Loopstick DT-200VX Created-- Equals Slider E10...

Gary DeBock
 

Hello John,
 
     Greetings from frozen (28 degrees) Puget Sound, and thanks for your comments.
 
     The Slider DT-200VX is indeed another sensitivity monster like the Slider E100's, but there are several reasons why this "Sangean Slider" will probably not be as popular as the Monster E100's. Although fully equal in astonishing sensitivty (and superior to the stock ICF-2010 and E1 models), the DT-200VX Slider lacks quite a few stellar attributes of the Monster E100's:
 
     1)  There is no bar graph, to peak the coil on the DX station's frequency.  It's an audio judgement only.
     2)  There is no 1 kHz tuning resolution, so there can be no trick like moving the Slider E100 1 kHz
               away from QRM.
     3)  There are four coil leads, not two like the E100.  And the four circuit board connections are truly
               microscopic, much trickier than those of the E100.
     4)  There is no premium 450 kHz ceramic filter available for razor-sharp selectivity (like the E100's
               Murata CFJ455K5).  There are some modest 450 kHz filters, however (like Guy used).
     5)  The DT-200VX and DT-400 cabinets provide a challenge to find any spot for attaching a
               loopstick mounting frame.
     6)  The 19 AM memories seem pretty lame, compared to the 200 of the E100's
     7)  The Sangean units have no simultaneous display of time and frequency, like the E100's
     
     Despite these limitations, the Slider DT-200VX and Slider DT-400W models would certainly be a popular choice for domestic DX, and far superior to the stock models in weak signal capability.  If Guy has some spare time this winter, perhaps we could work together like we did for the E100 transformation last summer, and find out what the top DXing performance level of these "Sangean Slider" models really is.  And I'll certainly be happy to write a detailed article on this transplant, hopefully right after the 2009 Shootout.
 
     73 and Stay Warm,

srf-59 selectivity

lrdheat
 

Tonight, my 59 has been much more selective than it's usual good capability. Locals on 1550, 1490, 1410, 1000, and 890 have always made it a challenge to find much of a window 10 KHz up or down from them. Instead of the usual narrow portion of a 360 degree circle that I could null out the locals +/- 10 KHz (indeed, on the 1490, it has always been very difficult to find a clear spot on 1500 or 1480), I was free of ALL of those locals 10 KHz up or down from them over the 360 degree sweep! The radio seemed to be hot! What in the world would cause a change in selectivity? Hope it lasts!

In reviewing my report, this was first heard on my Sony SRF-59 which I paralleled against a Sony ICF-2010 as WGR 550 in Buffalo New York carried the same program although there was a delay of several seconds between the two stations. ULR QSL #2. Very nice to see stations actually mailing postcards again.

7.5" Slider Loopstick DT-200VX Created-- Equals Slider E100's in Sensitivity

Gary DeBock
 

Hello Guys,
 
     In preparation for making an ultra-sensitive Sangean DT-400W model, an experimental loopstick consisting of a movable coil of 40/44 Litz wire was wound on an Amidon type 61 7.5" ferrite bar, and transplanted into a Sangean DT-200VX model (which has the same loopstick as the DT-400W).  The result was another ultra-sensitive radio, with weak-signal capability exceeding that of the stock ICF-2010 and E1, and equal to that of the new Slider E100's.
 
     The DT-200VX/ DT-400W stock coil system consists of a base coil of .196 microhenry inductance (at the 600 kHz peak position on the ferrite bar), and a smaller "piggybacked" coil of .016 microhenries.  The piggybacked coil is wound on the side of the base coil closest to the center position of the ferrite bar.
 
     Initial tests at night revealed equal sensitivity with the new Slider E100 radios, which have become very popular among the Ultralight enthusiast group.  Two weak nighttime signals were used to check this-- the Yakima TIS on 1610 kHz, and the INE beacon on 521 kHz.
 
     Despite the supremely high sensitivity, the Slider DT-200VX lacks the relative signal strength bar graph of the E100, making the coil peaking strictly an audio judgement task.  It also lacks the E100's ability to tune in 1 kHz increments, making it unlikely to compete with the new Slider E100's in popularity among transoceanic DXers.  As might be expected, the selectivity with the stock IF filter is also a shade less favorable than the Slider-only E100, matching the relative selectivity performance of the stock models.  However, for those with dreams of making their Sangean DT-200VX or DT-400W models ultra-sensitive for supreme weak signal DXing, the new Slider DT-200VX is an exciting reality.

Yes--Kevin Schanilec's article. Here is the direct link for those who
haven't seen it yet:

I suppose you could call it a type of diversity reception, but it's
really far more low-tech than that. It's just a scheme I read on
dxer.ca
where you connect the output of two identical receivers such that
one is
electrically out of phase with the other and feed the result to a
mono
earphone. The method then is to set both radios on the same
frequency,
but to place one so that it maximises a strong station while a
weaker
station is tuned on the second receiver. By adjusting volume and
placement
one can somewhat cancel out the strong station to better hear the
weaker
station's audio.

Obviously it's no replcement for antenna phasing and much less
efficient but it is interesting nevertheless.

I think the original article on dxer.ca (sorry, I can't remember the
author's name) describes it much better than I do.

new Cuban log

Carl DeWhitt
 

I logged a new Radio Reloj freqqquency last night at 2223-2229 EST on
12.17.08.poor to very poor reception with a couple of Radio Reloj
i.d.,s by om announcer and the telltale.
'RR" cw i.d.,s with WBAP nulled.This was barefoot on the SRF-59.
Station totals here in Tennessee are now at 223.My logs of Cuban
stations have definetly gone up since i moved to east Tennessee from
Oklahoma.I will post my Cuban totals soon.
