Gary:

I had to be Enid early this morning, so I wasn't able to listen like I wished. I did turn on a barefoot PL-310 for a couple of minutes before 1100 UTC and there were weak carriers on 774 and 972 kHz. Last evening, the France Info station on 1377 kHz was audible with the best signal of the fall. Hopefully TP signal propagation will be better tomorrow.

Re: Puyallup, WA Ultralight TP's for 11-3

I would have tried for some TPs this morning, but I slept right through my 6:15am alarm. (Sunrise is 7:15am for local AM stations, at least until DST goes off next Sunday.) (Maybe I should use something other than KFI, although now that baseball postseason is over it's not going to be XEPRS, at least till next spring probably.)

As for checking the soft-mute of the PL-606, I would like to suggest one way to do it. Find a signal that's somewhat weak but readable (and above any soft-mute threshold that may exist) when you aim at the transmitter, that can be nulled completely by rotating the PL-606. While listening to the signal, you can slowly rotate the radio to weaken the signal until it sinks down into the noise. If you hear any steps in the level, it definitely has soft mute. (As for how to actually measure it, though, I'm not sure how to do that.)
Alternately, if you're getting similar midday AM skip that I seem to be experiencing right now, you could find a weak to medium signal toward the upper end of the band (usually above 1500 kHz) that's normally unreadable midday in summer, and listen to it.
A third way would be to take a relatively steady weak-to-medium signal (barefoot SNR shouldn't exceed about 15-20dB or so), then take one of the smaller loops near it and slowly detune the loop to notch out the signal, listening for any steps in the audio level.

Also what does the barefoot PL-606 read on 1450-KSUH and on 1430 and 1470 (or if stations are audible there, 1435 and 1465), when facing KSUH, and also when nulling KSUH?

Hello All,

This morning's Asian signals ranged from comatose (at 1300) to fair
(around 1420), with some moderately good "big gun" TP audio during brief
moments. The first band check at 1300 was miserable indeed, with even all the
Asian carriers way down in the noise (this was probably the same situation
that Bill noted). The comatose band gave every impression of being down for
the count, although around 1330 the dead carriers started springing to
life, and before 1400 a few "big guns" like 747 and 774 were producing fair
audio through the domestic splatter. The situation continued to gradually
improve until around 1420, when 738-BEL2 produced enough fair Chinese audio
for a "soft mute" test of the new Tecsun PL-606 Ultralight radio model (more
later). The second-tier TP's never really got out of the gate this morning,
though, and the usual Chinese overachievers like 936-Anhui and 1377-CNR1
were silent. Several Asian powerhouses like 648-VOR and 972-HLCA were decent
around 1430, though, and 657-Pyongyang got in a few weak Korean tirades
before the band collapsed around 1445. In general the morning's session was
lackluster, but certainly much better than its prognosis at 1300.

The following were heard on a C.Crane SWP Slider model (7.5"
loopstick) and a new Tecsun PL-606 stock model, inductively coupled to a 9' sided
PVC tuned passive loop (in the cold back yard). A modified ICF-2010 (30"

For those interested in the new Tecsun PL-606 (the newest 1 kHz DSP
Ultralight model), a "soft mute" test was run on the fair signal from
738-BEL2 (Taiwan, in Chinese) at 1420 this morning. The new PL-606 was
inductively coupled to the 9' PVC loop, and a recording was made on 738 kHz for the
first 20 seconds, and then on 737 kHz (1 kHz farther from the 740-KCBS
splatter) for the next 21 seconds.

Although the KCBS splatter and 2 kHz heterodyne disappeared on 737, so did
much of Taiwan's signal, unfortunately. In this respect the new Tecsun
PL-606 may resemble its PL-310 sibling, more than the reduced-soft-mute PL-380
model. Further tests are planned later today on the highly sensitive new
radio, the most compact 1 kHz DSP Ultralight on the market.

Anyone need a Tecsun PL-380

neilbellgroups <neil.bell@...>
 

Two months ago a friend of mine asked me for a suggested radio for him to get that was small but good enough to receive SF Bay area stations while he traveled up and down the California Central Valley. He works for a farm equipment and fertilizer supplier and the radio I got for him was a PL-380 which met his needs very well.

Now he was just promoted to a desk job here in the bay area and no longer travels or needs his Tecsun and asked me to try and sell it for him. He paid about $60 to a Hong Kong shipper and has asked me to try and sell it for $45, which includes shipping by priority mail.

I have his radio and it checks out 100% okay, no dings or scratches and has the manual, USB / AC plug-in supply for charging batteries, earphones, antenna, original box and protective zip-up case. It is just 2 months old.

If interested contact me via e-mail please.

Re: So what is DX let me tell you.

ferrite61 <dxrx@...>
 

The first example is quite doable at 12.8 km/Watt, the other one is over 300 km/Watt. I wouldn't spend too much time listening for the latter. I will say that 4 Watts at 40km eludes me, but 40 Watts at 400 km does not. As a matter of fact, anything under 20 Watts at any distance amounts to 2 receptions here. Could be a power floor along with that noise floor. ;o)

Good morning, fellow DX'ers!

I was having trouble staying asleep - I have a really big work task that is stressing me out - so I put in my earbuds, turned on my Sangean DT-400W, and was rewarded with a new station!

I had been tuning around earlier last night and had left the radio on 1250 kHz, so that's what it was on this morning.  I adjusted the radio to get rid of the splash from local KQUE-1230 and heard "X-E-S-J 12-50," which is one of my target stations.

Yep!  I had heard XESJ 1250 in Saltillo, Coahuila, Mexico!  I heard two good ID's, one at 0814 GMT (3:14 AM CDT) and the other at 08:21 GMT (3:21 AM CDT).  I'm not as good at identifying Mexican musical styles as others on this list, but the music played between ID's sounded like either "Ranchera" or "Nortena."

With the new station heard, I drifted to sleep.  It's amazing what DX'ing can do to frazzled nerves!!

73 and Great DX!

Re: Newfoundland Ultralight Trans-Atlantics Report Nov 1

Hi Allen and all,

I listened last night on 1179 from my location in Blackpool, England.

I caught an ID of "Cadena SER" - audible on the following clip: http://www.youtube.com/watch?v=P8j6HlslbUg
which was probably Valencia (50kW). (Several Cadena SER freqs earlier had a parallel commentary of Valencia v Rangers UEFA Champions' League). The other station was Deutsche Welle, I heard an ID during an earlier English segment, which had included a talk about relations between Russia and the USA in American English. I also heard a French segment. The video has a German News bulletin (22:00 UTC). I can't find this listed, although there is a listed 10kW transmitter in Germany, this is down as relaying RFI not Deutsche Welle. Comments anyone?

Both of these stations were caught on my barefoot Sony SRF-59, Eton G8 and Sangean ATS-909 (The latter two radios are in the video)

Peter, Blackpool UK

An interesting frequency in the logs now is 1179 khz as Radio Sweden often heard here prior has shut down on that outlet. Spanish
songs ,Blue Seude Shoes

1179 khz – Unidentified 20:17 UT/1 Unknown language (News clips in English)
1179 khz – Unidentified 19:47 UT/1 Spanish by 2 men and a woman (presumed SER Valencia possibly )

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).

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!!

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.)

Subject: [ultralightdx] Your DSP radio readings on/±20kHz strongest midday
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!
