That's OK, Richard. Concentrating on hearing trans-Oceanic stations has been slowing my number count for about 3 years now :-) Rob has logged about 4 times as many stations as me, but I probably have him beat in overall DXing mileage. Too bad there's no award for that, but I'm not complaining (because I can make up a fake Award Certificate up anytime I wish).
 
73, Gary

It was good to see your see your message to Kirk. I'm sorry to read of your the loss in your family. Let me warn that I'm not sure retirement is all it suppose to be.

At the rate you're going, you will probably log 900 before I make it to 800. I did manage to log station 777 last week. Concentrating on hearing trans-Oceanic stations definitely slowed my number count.

Best wishes and continued good DX.

Keep Chuggin' Kirk.................

Kirk.........Great work on your recent New Catches bringing your ULR Totals close to the 700 Mark!!! I'm confident you will hit # 700 very soon!! When we all started DXing with these Tiny Marvels a few years ago...we never imagined we could log 700 Stations with them....heck I didn't even think 500 was possible...but we've sure blown that outta the water eh!!???

Your efforts to continually dig out the new ones are what gives other Dxers in this group the motivation to stretch the limits of ULR DXing!! Keep up the good work Kirk....and we look forward to issuing your 700 Stations Heard award very soon.

I, on the other hand have been slacking off in the New Ones Department due to a death in the Family which has re-directed my priorities for the last 2 months. I don't think I was able to even turn on the Radio during the month of October!! Nothing new logged here in a LONG TIME....it seems like I've been stuck at 844 Heard for eons!! However, things are slowly returning to normal, but it looks like my Dream of hitting 900 Stations Heard on a ULR by the end of 2010 is not going to materialize! However my Retirement is quickly approaching as I now have only 38 Work Days left...but who's counting eh!!?? After Jan/18th....I will find myself with lots more time to DX, and enjoy other things that there just aren't enough time for now.........

Hope to be back at the Dials soon....in the meantime, I'll be rooting for Kirk in his quest to log 700 Stations on a ULR!!

Contests?

cdhascall@att.net <cdhascall@...>
 

Have there been any more (or will there be more) contests? I took part in the "Sprint" and the "Fall Follies." I added dozens to the ULR book and a few to the overall log and had great fun, in doing so.

Gary is indeed the man. He hooked me up with an Eton e-100 for which I am grateful. Curtis Sadowski in Illinois helped me get my first ULR, a Sony SRF-59. These guys, along with Kevin S., the late John Bryant, Steve Ratzlaf, Robert Ross and on and on have been very helpful too.

I'm certainly not complaining...I personally would include the G6 as a ulr...yet, respectfully accept the ulr group definitions and reasoning. I'll add that the joy of the hobby shines through in the posts from groupmembers, and the amazing generosity (actively spreading the good gospel of the great hobby of ulr dxing) of folks like Gary to alligned stock ulr's or add 7.5" ferrite bars (installed!) is remarkable.

I have always felt I am a welcome guest in this group. Many very knowledgeable members have very patiently answered my questions and pointing me in the right direction. As a guest, I never complain about my hosts furniture or the food offered. There has been little or no change in the rules about ULR's since I have been here, and even if there had been, it would have been done by the hosts who work very hard to run this group. - FARMERIK


Re: Your DSP radio readings on/±20kHz strongest midday signals (incl. nulls)?

I would, if so many of the stations I wanted to listen to in the daytime (560-KBLU, 580-KSAZ, 660-KTNN or 660-KWVE, 680-KNBR, 700-KALL (as for last 2, 77kW 690-XEWW 32 miles distant could be a challenge), 720-KDWN, 770-KCBC or 770-K780-KAZM, 810-KGO, 840-KXNT, 870-KRLA, 890-KLFF, 920-KPSI (5kW 910-KECR at 9.3 miles is probably a challenge here), 960-KIXW, 970-KNWZ- 980-KFWB, 1010-KXPS, 1100-KFNX, 1110-KDIS, 1140-KNWQ (being 6.3 miles from 10kW 1130-KSDO probably doesn't help), 1150-KTLK, 1180-KERN (being 9.3 miles from 50kW 1170-KCBQ I'm sure doesn't help), 1200-KYAA, 1230-KXO, 1260-KGIL, 1290-KZSB, 1300-KROP, 1320-KKSM, 1340-KCLU, 1350-KTDD (5kW 1360-KLSD splatters and covers the desired signal on my PL-380 from 8.3 miles away even in 1kHz BW mode, like the previously mentioned pests also do to their nearby desired signals), 1380-KLPZ, 1400-KESQ or 1400-KKZZ, 1430-KWST, 1440-KFNY, 1460-KTYM, 1490-KGBA or 1490-KSPE, 1510-KSPA, 1520-KVTA, 1560-KNZR) weren't so badly obliterated by desense, or in some cases, splatter. Most of the listed stations, except a few, are completely unreadable on my Panasonic RQ-SW20 in the daytime, my previous radio for which I've been trying to find a replacement that will hear at least most of those stations as strong as possible without any side splatter. I would have added a few more stations to the list, but IBOC from some stations 10kHz away would have covered them up anyway, and only 1 or 2, IIRC, were barely readable before the stations started using IBOC.
I'm basically wondering if my PL-380 is the only one that desenses so badly near strong signals. For example, 1170-KCBQ (non-IBOC) reads 77,25 on the G8 (which is going back to the store today), and on my PL-380 reads 45,00 on 1150 and 43,00 on 1190. The manual for the PL-606 states selectivity as >60dB at +/-9kHz in 3kHz BW mode, and therefore I'd expect to see 17,00 on 1161 and 1179 kHz on that radio (I don't have one) without any trace of audible splatter at all (which is audible to some degree from 1155 to 1185 on my PL-380 in 3kHz BW mode).

I've already proven that the elevated RSSI readings is actually desense and not just high ambient noise, by the reduced readings when the strong signal is nulled. Interestingly, the audible noise is actually LOUDER on the signals that aren't desensed so bad (for example, noise on a 15,00 sounds considerably louder than on a 45,00 channel). This seems to indicate to me that although there's no audio splatter heard very far beyond a channel, there could still be some form of side signal in there somewhere that's made it through the radio's filters. Also, I've noticed at least one, if not more cases, where a signal was noticeably more readable at a location farther away from a nearby pest, even though it was also farther away from the desired signal. For example, KDIS-1110 indicates about 43dBu RSSI, 0dB SNR a couple miles south of El Cajon, CA (112 miles to KDIS, 10kW pest 1130-KSDO is 72,25 on the G8 from 6.3 miles away), and is about 15dBu RSSI, 10dB SNR at Cameron Corners, CA (135 miles to KDIS, KSDO's directional signal reads 25,25 here on the PL-380).

I'm looking forward to learning more about the PL-606's performance, for example to see if it measures up to the specs in the manual. If it does, then maybe that radio might at least enable me to hear some of the stations I want to hear. (I didn't originally come here to participate in contests, I originally came to see about finding a radio with which I could hear several stations I wanted to listen to that were usually inaudible on my Panasonic RQ-SW20, and I knew I wanted to keep it in the ultralight size and price range, as I was looking for a not-too-expensive pocket AM radio.)

signals (incl. nulls)?

 
Mine:

1110      43,00 | 30,00 | 20,00
1130-KSDO 72,25 | 43,25 | 19,00
1150      45,00 | 34,00 | 19,00
1170-KCBQ 77,25 | 54,25 | 15,00
1190      43,00 | 29,00 | 15,00

First is when facing the transmitter, second is when rotating for a null (radio
is still horizontal) and third is when tilting for maximum null.  In my case, I
have two strong stations 40 kHz apart, both basically north of me.  The
strongest one, 50kW 1170-KCBQ, is 9.3 miles away, heading 7°, and the runner-up,
10kW 1130-KSDO, is 6.3 miles away, heading 350°.  The difference in heading, and
the fact that the tilt null is extremely narrow, accounts for why the 1110 tilt
reading is higher than the 1130 reading, which was higher than that of 1170 -
KCBQ's signal was upwards of 50-something dBu IIRC (I didn't take a note of it
though) when 1130 was tilt-nulled.
On 1110, KDIS is faintly audible, but doesn't come anywhere near pushing through
the 0dB barrier.  On 1190, I can barely make out KXMX, but I think KTLK is too
far under the desense on 1150 to be heard.

Now... how do your DSP radios behave?  I'd like to know the readings on the
strongest station, and the readings +/-20kHz.  (If your radio has selectable
bandwidths, set it to 3kHz to level the playing field.)  If there are audible
stations on those frequencies, either post only the one that doesn't have any
audible station (unless the SNR is 0dB), or post the +/-15kHz readings, unless
it's an IBOC station.  Also, like I posted, I'd like to see the numbers when the
strong station is nulled.  (You don't have to do the tilt null, unless you want
to.)  If your strongest station is such that you're getting 49,00 or 50,00
readings, then post over what range of frequencies you get those readings.  For
example, at my grandma's house in San Gabriel I get somewhere around 85-90dBu if
not more on 23kW 1300-KAZN and 50kW 1430-KMRB, both of which are diplexing from
1/3 mile away and visible from her front yard.  There, I get 50,00 readings from
about 1200-1550 and 49,00 from about 960-1710.

Is my PL-380 and the G8 (which is going back to Radio-Shack tomorrow, although I
may buy another one later as I didn't get to finish some comparisons I wanted to
do) the only radios that show high RSSI levels on channels around strong
signals?  I'm hoping to see some data, and compare to my own PL-380.  I
especially would like to know if the PL-606 lives up to spec.  The manual states
60dB selectivity in 3kHz BW when tuned +/-9kHz.  If that's true, should I
expect a 75dBu station to be reading 15dBu at +/- 9+ kHz, or a 90dBu station to
be reading 30dBu at 9kHz (and lower when tuned farther off at a rate of
9.5dB/kHz, calculated by assuming the BW is +/-3dB, and dividing the dB
difference (60-3=57) by the frequency difference (9-3=6) - 57/6 = 9.5)?

Latest DX From Ponca City

Kirk <kirk74601@...>
 

For the last couple of days I've been DXing from a different QTH here in Ponca City, OK. I was VERY surprised that there's absolutely no electrical noise at all! This is by far the best DX site I've ever had within any city limits. (Hope I didn't just jinx myself.)

I have three new stations to report along w/an interesting UNID station. All of these were logged on the trusty E-100 Slider and a SAT.

THANKS TO RICHARD ALLEN FOR THE TIP ON THIS ONE!
1580, KGAF, Gainseville, TX, 0530 UTC, 11/1/10, this one was fading in and out along w/ what sounded like 10 other stations. Faint C&W mx(I think) followed by an ID. "Your hometown radio station, KGAF..."
ULR Sta #695

1580, KXZZ, Lake Charles, LA, 0611 UTC, 11/1/10, this one faded up to a G lvl for abt 5 minutes. Call ltr ID was hrd along with urban mx.
ULR Sta #696

700, XEDKR, Guadalajara, Jalisco, 1230 UTC, 11/1/10, Seemed to be all tlk. Vy nice IDs were hrd. "Radio Red AM, tu radio."
ULR Sta #697, LAm #124

1580, UNID, 0600 UTC, 11/2/10, I'm not sure what this all about, but I hrd a sta there carrying XERF (1570) pgm'g. Checked this one four different radios, and this was hrd on all of them. I've no idea if this is some sort of spur or another sta simulcasting XERF. Vy strange. Does anyone know anything abt this one??

Wishing you all good DX...hope the TAs and TPs start picking back up. Gary, I can hardly wait to use the Murata E-100 for these!!
73 and good DX to you all!

Puyallup, WA Ultralight TP's for 11-2

Gary DeBock
 

Hello All,
 
     Asian signals never really sounded very healthy this morning, although fair TP audio was in and out from various stations for almost the entire DXing session (from 1300-1450). The "big gun" Asians (594, 738, 747, 828, 972, 1134 and 1566) took turns fading in and out from 1300-1400, when the entire band seemed to take a momentary dive (also noted by Walt). TP signals slowly recovered up to a mediocre level around 1415, but the sunrise enhancement didn't provide any additional signal boost, and the same collection of "big gun" Asians stuck around at a fair level until the band collapsed a little early, around 1450. A few stations like 648-VOR, 936-Anhui and 1377-CNR1 occasionally managed fairly decent audio to escape the mediocre trend, but it was gone in a flash. In general, the session was nothing to shout about.
 
     The following were heard on a C.Crane SWP Slider model (7.5" loopstick) inductively coupled to a 9' sided PVC tuned passive loop (in the back yard). A modified ICF-2010 (30" loopstick) was used as an SSB spotting receiver:

Hi Richard,
 
The Asians weren't all that much stronger here on the west coast this morning, although we did have some anemic audio on the "big gun" TP's. Some fair audio from 1215-Absolute showed up in the Victoria, BC area last night, but a 1210 Spanish pest wipes out that frequency here. Still waiting for the first TA audio of the 2010 Fall Season, after 6 stations from Europe (and west Asia) were received here last year. TP reception on the east coast seems equally mediocre.
 
73, Gary

It was another rotten morning of not hearing TP signals in the heartland. I listened at 1225-1304 UTC and heard carriers, with no audio, on 558, 648, 702, 774, 792, 828 and 972 kHz. The strongest signals were 828 (JOBB?) and 972 (HLCA?). Receiver: Tecsun PL-310 with 7.5-inch loopstick. Local sunrise was 1254 UTC.

I listened briefly last evening and heard barely audible talk on 1215 kHz after 0619 UTC.

Good DX all. And for those still trying to figure it out, DX is whatever you want it to be. There is no definitive answer. So set a goal and attempt to reach it. Once you've achieved that, reach a little further.

Oklahoma TP's 11-2-10

It was another rotten morning of not hearing TP signals in the heartland. I listened at 1225-1304 UTC and heard carriers, with no audio, on 558, 648, 702, 774, 792, 828 and 972 kHz. The strongest signals were 828 (JOBB?) and 972 (HLCA?). Receiver: Tecsun PL-310 with 7.5-inch loopstick. Local sunrise was 1254 UTC.

I listened briefly last evening and heard barely audible talk on 1215 kHz after 0619 UTC.

Good DX all. And for those still trying to figure it out, DX is whatever you want it to be. There is no definitive answer. So set a goal and attempt to reach it. Once you've achieved that, reach a little further.

Re: ferrite vs sensitivity

Pollock,Raphael E <rpollock@...>
 

Dear George: These graphs are very interesting, especially the implications concerning length of ferrite as a function of inductance. I have worked with 125 mu bars, and it is apparent that extra length in 125 mu bars beyond somewhere around 16" doesn't really appear buy you an advantage; at that length of bar you are already on the shoulder of what appears to be a logarithmic plot--again, thank you for providing this information.
 
As a practical matter, I would be very interested to see how you would apply these findings in the design of an "optimal" ferrite booster bar type antenna to be inductively coupled to a radio with an internal ferrite bar antenna, seeking to come up with the best possible combination of parameters; i.e., bar length, bar diameter, bar inductance, coil position on bar, coil wire composition, "tightness" of coil wrap, etc.
 
Any insights would be deeply appreciated!

Thank you for the kind remarks.  I promised to post some more graphs
so here are my latest.

I stopped assuming in my calculations that the permeability of a
ferrite rod was fixed because this simply was not true.  I found an
approximation in Google Books which I use now to account for the fact
that permeability changes with rod length.

Looking at my updated graphs, the matched condition that I mentioned
before still exists but it occurs at lengths so small - like 2" for a
D=.5" rod and 4" for a D=1" rod - that it doesn't really matter.

From Faraday's law of induction, we know that flux flowing through a
loop causes a voltage to appear across it.  So the more flux the more
voltage we can get out of one turn.  Around the point where the rod is
long enough to reach its initial permeability lengthening it will only
ever so slowly increase the amount of flux in the rod, as you can see
in the following graphs.  In the graphs, B is the flux density, in
Tesla, E is the E-field, in V/m, and H is the H-field, in A/m.  H is
derived from E using H = E/377.  B = mu0*H where mu0 is the
permeability of free space.  B was then used to calculate the flux in
the rod.


http://img193.imageshack.us/img193/2166/flux40.png

I also plotted the voltage output at 1 Mhz for the various rods.  Each
rod is wound with the right number of turns over its full length to
reach 250 uH.  The formula used to calculate the voltage output of
the loop is Q*2*pi*f*N*flux_in_rod, where N is the number of turns.
Plots at other frequencies give similar results when tuned at the same
capacitance.


http://img844.imageshack.us/img844/6829/dbv40.png

I also tried the other formula I've seen, Q*2*pi*f*N*Area*mu0*mu_rod*H.
The results look the same except the voltage is about 10 dB more.
Reality is probably somewhere in between since B and H influence each
other.

Re: Kchibo D96L woes

Guido Santacana <foxam2001@...>
 

Hi Robb,

  It seems to be that way. The noise level is just overwhelming. If you hold it in your hand, you have to touch the telescopic antenna with your finger to hear any stations or everything is swamped by noise and interference from locals. This happens mainly on SW. On medium wave there is a motorboating sound coming at 520kHz when the display is lit up. This sound becomes a hash at higher frequencies and makes it difficult to tune. On the Tecsun PL300 I can hear WWV at 5000 kHz with the telescopic whip. On the D96L it pops up sometimes above so much noise. I have found that at least stronger SW stations can be heard as long as you don't touch the case. The external antenna is of no use at all. It increases the noise to intolerable levels. I am about to open it up and check if all the connections are ok or something happened in transit. I read about someone having a similar experience.

Best,

Guido

Dear Guido,
 
It sounds like you may have a dud radio. You mentioned the G8 performing much better, so this shows something drasticlly wrong with the kchibo. However, as I have learnt, the DSP seem to hate "radio blasts" from high powered local stations, it could perhaps be the case? But since this is not just on a few frequencies I sadly beleive you are simply in the possession of a bad fuctioning radio. I am very sad when I purchase a bad radio and spend nearly 1/2 the price posting it back. I'm sorry my news wasn't positive. Don't give up ;-)

Re: Tecsun PL-606 AM-FM-SW DSP Receiver-- First Impressions

pianoplayer88key
 

I'd be interested in knowing if it performs up to spec. For example, the manual specifies selectivity to be >60dB when BW = 3kHz and you tune +/-9kHz. If 1450-KSUH reads 75dBu, should I expect 1441 and 1459 to read 15dBu?
If it does as the manual says, it would significantly outperform my PL-380, which reads about 43dBu or so when tuned 20kHz off a 77dBu signal (measured with the G8 as my PL-380 caps at 63dBu).
Also, is the tuning knob built better than on the PL-380? And could you by any chance post comparison pics with a few units (PL-606, PL-380, others of your choice) so we can get a visual idea of the size difference?

Hello All,

Tecsun's newest Si4734 DSP-chip Ultralight radio has apparently
attracted some serious interest among our enthusiast group, judging from the 76
members who have already downloaded the PL-606 owner's manual (at
_http://www.mediafire.com/?msaeidp58598crt_
(http://www.mediafire.com/?msaeidp58598crt) ). Judging from initial testing here, this latest Tecsun 1 kHz DSP
model will do a fine job of meeting expectations.
Arriving 5 days after an EMS order was placed with the eBay seller
"Anon-co," my black colored PL-606 was eagerly unpacked, along with multiple
accessories. At first glace, the compact radio resembles a slightly
shrunken PL-380, minus the direct-entry keypad. The radio is noticeably smaller
and lighter than either the PL-310 or PL-380, and uses only two AA batteries,
instead of the three powering the larger radios. For those who thought
that the PL-310 was a little large for their shirt pocket, the PL-606 should
be a very comfortable fit. Like the PL-380, the radio uses thumb wheel
tuning, instead of the PL-310-style tuning knob. The dual 1/10 kHz tuning rate
is still used (depending upon the rotation speed of the thumb wheel), but in
the PL-606 the system seems more user-friendly than in the PL-310, with
the 1 kHz tuning rate sticking around unless the thumb wheel rotation is very
fast.
In the test which will probably draw the most interest, the new
PL-606's AM sensitivity was thoroughly checked against that of both the PL-310
and PL-380. Because of the PL-606's smaller cabinet expectations were not
high, but the new radio actually outperformed the PL-380 in S/N and RSSI
readings on both the 530 and 1650 kHz TIS stations, and at least matched the
PL-310's AM sensitivity on both stations. The PL-606's audio signal recovery
on both frequencies was superior to that of the PL-380, and equal to that
of the larger PL-310. These testing results were quite unexpected, and
immediately provided motivation to order a couple more of these overachieving
little wonders for loopstick replacement experiments.
Further testing will include soft-mute comparisons, SW testing and FM
performance, the detailed results of which will be included in the
upcoming AM-DX Shootout review. In summary, the newest Si4734 1 kHz DSP model
seems like a real winner, and may well be the compact Transoceanic-DX
Ultralight that many members have been waiting for.
