[IRCA] TP 3 Dec Victoria version

[Nick Hall-Patch]

A different morning again.   The Chinese didn't really appear, 
especially later, though some action from China after 1300UT.   More 
Japanese inclined conditions overall, as early as 1100UT, plus HLAZ 
didn't stop delivering its final audio until 1827UT.






pretty darn good audio (all of it understandable by a native speaker, 
at least briefly):


594 JOAK Japanese man in Japanese 1505UT
774 JOUB man in Japanese 1508UT
828 JOBB briefly at this level //774 1509UT
972 HLCA woman in Korean 1459UT, then pips, dominating 970 if both 
included in an AM passband






Reasonable audio  at  times during the period (much of it 
understandable by a native speaker, though often battling w/splash or noise):



567JOIK woman in Japanese //594 1514UT
747 JOIB man in Japanese 1508UT
873 JOGB man in Japanese //774 1506UT, woman talking underneath (N. Korea?)
1053 Korean jammer 1400UT
1566 HLAZ man in Chinese 1521UT, only briefly fair during sunrise 
enhancement, but wouldn't quit, just kept fading up, with one 
particularly good one at 1734UT woman in Korean over piano music, 
equal to earlier peak levels.  Last audio, "O Come All Ye Faithful" 
carol 1827UT




not so reasonable audio, occasional words or phrases in splash or 
noise could be understood by a native speaker:




702 NHK2 woman in Japanese //774 1509UT
837 man in Chinese 1348UT, then another man shouting, 
sports?   CNR5?? no parallels available though 1116 may have had a 
hint of shouting on it.  Next time.

945 CNR1 man in Chinese //6125 1513UT
963 CRI man in Russian 1311UT
1134 JOQR briefly w/womn in Japanese 1502UT
1206 Yanbian man in Korean 1315UT
1287 JOHR man in Japanese to another man on phone 1520UT




Burbles in the splatter and noise (if lucky, language might be 
guessed at by cadence of talk, or parallel established by changes in 
talk or music)



603 soft music, man talking slowly 1518UT
666 JOBK Japanese man //594 1501UT
693 JOAB man in Japanese //774 1516UT, sneaking past murderous 690 splash
918 no pips at 1400UT, news sounder,  woman talking, Chinese inflection?
954 man and woman talking Japanese inflection 1520UT
981 woman talking insistently, Chinese? 1305UT
1044 CRI faint traces of fanfare in the murk 1400UT
1143 woman talking Chinese inflection 1502UT
1242 man and woman talking Japanese inflection 1529UT
1422 woman talking Japanese inflection 1521UT



Strongish het, no or "near imaginary" audio (either undermodulated or 
ravaged by splatter) lots of near audio here



531 855 909 936  1035 1098 1116 1269  1422 1476

It's mostly just carriers on 1215 and 1089 here for the moment 
(0400UT).  Still, that is far more than has been heard recently from Europe.

[IRCA] Alberta TPs for 3 December 2016

[Nigel Pimblett]

 I knew full this morning that reception was unlikely to match 
yesterday's stellar performance.   That indeed turned out to be the 
case, as the Japanese big guns again did well, down only a little from 
yesterday, but the second tier Japanese in general weren't making audio 
today.




594JOAKTokyo, JAPANAlready good at 1259 with woman in 
Japanese, then time pips at the hour.


639	unID	JAPAN	Heard NHK time pips at 1300, but not enough signal to 
know whether it was NHK1 or NHK2.


666JOBKOsaka, JAPANInstrumental music, then man talking in 
Japanese at 1415, //594.


693JOABTokyo, JAPANDidn't do much until 1330, when noted 
with man in Japanese thru splatter.  CBU was more potent than normal 
today for some reason.


729	JOCK	Nagoya, JAPAN	Nothing like yesterday's signal, but heard time 
pips, then man in Japanese at 1300.


747 JOIBSapporo, JAPAN   Man in Japanese, good level at 1405.

774JOUBAkita, JAPANNot quite at yesterday's level, but still 
had a potent signal at 1403 with man in Japanese.


828JOBBOsaka, JAPANFirst noted at 1300 with time pips, then 
few seconds of music before going into language lesson.  The strongest 
TP at 1300.


1071unIDHeard NHK stye time pips at 1300, but little else.  JOFK?

1098	V7AB	Majuro, MARSHALL IS	Weak signal, but the vocals had a distinct 
island flair, so assume Marshalls.  This at 1057.


1116	unID	Back to 4BC heard today, with man talking at 1259, then time 
pips and into news by woman.


1188	JOKP	Kitami, JAPAN	Poor, with woman in Japanese at 1259, then NHK 
time pips.


1566HLAZCheju, S.KOREAFair with Christmas hymn at 1257, then 
talk in Japanese.



If I hadn't experienced yesterday, today would have seemed quite lively 
relative to recent weeks.  774 was actually doing well at 0655 last 
night, even before I went to bed.

[IRCA] Puyallup, WA Ultralight TP's for 12-3

[d1028gary]

As Bill and Richard have reported it was another good day for Asian signals, 
with several second-tier TP's joining the usual big guns with decent audio at 
times. Propagation seemed to shift a little from the Chinese stations to those 
of Japan and Korea, though. 

A long session in the cold back yard started at 1200, with very good audio from 
the Japanese big guns on 594, 693, 747, 774, 828 and 1287, along with the 
Koreans on 972, 1053 and 1566. Although the Chinese stations on 936, 1017, 
1044, 1206 and 1323 were managing some weak audio at times their predawn 
signals never quite matched yesterday's levels, and the usual second-tier 
Asians on 603, 657 and 738 also didn't repeat their predawn levels. About the 
only Chinese stations that went against the trend were the 1035-CNR1 synchros, 
with their distinctive echoes slightly stronger this morning. The Japanese big 
guns were especially strong both prior to and after dawn, with 594-JOAK, 
693-JOAB, 747-JOIB and 774-JOUB reaching excellent levels at times. 972-HLCA 
and 1566-HLAZ also had their moments of excellent audio in the predawn darkness 
from 1200-1400, although their signals seemed to taper off after daybreak. 
603-HLSA, 657-Pyongyang and 738-BEL2 all got somewhat of a boost during d
 awn enhancement (along with 1035-CNR1), but overall ended up weaker than 
yesterday's levels. The CRI stations on 1017, 1044, 1206 and 1323 also played 
hide-and-seek during dawn enhancement, with none of them maintaining decent 
audio for more than a few seconds at a time. By comparison they all had better 
peaks during yesterday's dawn session. Best signals of the session (all 
excellent) were from 594, 693, 774, 828 and 1566 in the predawn darkness from 
1300-1330.

Re: [IRCA] North Korean MW Jamming

[Richard N. Allen]

Chris:

Thank you for the interesting report about radio jamming in the Koreas.   
Sadly, it's doubtful I will ever hear any other than on 1053 kHz here in 
Oklahoma.  It took me down memory lane to the jammers I use to hear in England 
in the late 1960s.  The most memorable was the East German one used against 
RIAS-Berlin on 990 kHz.  There were others but it's the one stuck in my mind.

Re: [IRCA] TP 2 Dec Victoria version

[Nick Hall-Patch]

Thanks for looking these over Chris.  Yesterday was a "deeper" 
morning than most, with a Chinese flavor, but this morning was back 
to a more normal Japanese collection of stations near local sunrise.


If you're interested, 
http://www3.telus.net/public/shallpat/test/display.htm will show you 
rough signal strengths here in Victoria on a minute by minute 
basis.  Yellow/orange/red coloring on the bars shown indicate likely 
audio receptions, and signals are peaking here in the 1400-1530UT 
time period, though HLAZ has been occasionally impressive up to a 
couple of hours after local sunrise .


best wishes,

Nick

Nice catches!! You got really far inland on those, so I'd call that 
a big success. I'm impressed!!!


Your 972 would be Henan Economic Radio most likely, 100kw. It 
regularly is heard behind 1500kw 972 in Seoul and is a really hard 
signal to shake. I've IDed it a few times under there and 972 is 
under 40 miles away. Nothing else with enough power to hear on that 
frequency in Chinese, anywhere.


918 would be Shandong People's Radio, Jinan (200kw). It's a mess of 
echoes in Seoul because there are other 50 and 10kw affiliates on 
the same frequency.


819 I'd imagine is Pyongyang. I doubt you'd hear MBC (never say 
never I guess). But that Korean inflection is drastically different 
between north and south. The northern media dialect (which doesn't 
resemble normal speech patterns) is very distinct, but sometimes 
they also run more normal programming with normal speech patterns.


1377 is obviously CNR-1 in Zhengzhou //Beijing (the reason your 972 
is even more obvious). That's far inland, but they get out strong 
into Seoul even at 600kw. I wonder about the distance of that, geez! 
They're the only CNR-1 on the frequency as well and the frequency 
isn't busy at all in the region.


756 is CNR-1 Harbin, 100kw (or one of the many smaller CNR-1s, but 
doubtful given your other stations from up that way). 756 is almost 
exclusively owned by CNR-1. There's a 10kw station in Japan and no 
stations whatsoever on 756 in Korea to hear.


1242 is obviously Nippon, Tokyo, 100kw as you likely suspect anyway. 
They play music and their unique cuckoo clock TOH ID sound. Nothing 
else to hear on there and 1242 in Korea recently went on super-low 
power. At 40 miles, you can barely hear the thing anymore whereas it 
used to pummel Tokyo, but no more.


All the others I'm sure you obviously know, such as the two 
Changchun signals (981, 1017) and Beijing. Anything else would be 
mere speculation on my part as you obviously have a fair number of 
10kw signals in there that you got.

[IRCA] Oklahoma TP DX 12/3/16

[Richard Allen]

It was a bit of a hit and miss DX session here with too many of the latter.  
But overall the best morning for awhile (LSR @ 1326 GMT).

567 JOIK? a trace of a signal (no audio) at 1228-1230, nothing later.
594 JOAK a barely audible-to-poor signal fading in and out from 1213 until 1334.
692 JOAB unreadable audio in KGGF-690 slop at 1330.
702 unID carrier from NW at 1311.
747 JOIB poor on SDR at 1131; barely audible with KNNJ splatter at 1223 & 1315 
on ULR. 
774 JOUB audible at 1118 to 1318 fading in and out, occasionally peaking at 
fair-to-good.  Best signal from JOUB since September, even audible on barefoot  
PL-310 for a time.
827 JOBB? het at 1228, very strong (sadly no audio) at 1330
972 HLCA? weak het in KCFO-970 QRM at 1322.
1566 HLAZ barely audible in XERF-1570 splash at 1300-1310; 
1593 unID (CNR?) traces of a signal at 1325.
No signals detected on 603, 657, 1053, 1134 1206 or 1503 when checked/

I finally resorted to using my old faithful PL-310 which was used barefoot to 
logged many of  the Asian signals heard in 2009-2010.

Re: [IRCA] North Korean MW Jamming

[John Fisher]

Hi Chris,

Thanks for an excellent piece of research on the Korean jammers and for 
sharing the audio clips. It is really informative, to hear all of the 
different styles of jamming.


I only wished that I had access to this type of information a number of 
years ago, when I used to frequently visit Korea for work.


Cheers

To follow up on my recent posting about South Korean jamming, here's some 
examples of what's going on north of the border, including an FM bonus 
clip. A radio acquaintance is operating a KiwiSDR node about 8 miles to 
the south of my Seoul location, but those 8 miles are just enough to lose 
the Pyongyang jammers that were typical within the city, so my recordings 
may actually be relatively rare and likely some of the only examples of 
North Korean jammers on many of these frequencies. They may exist here and 
there in the local Korean DX community (seemingly unlikely as well) but 
not in the international forum for sure, especially as bringing a radio 
into the DPRK as a tourist is quite highly discouraged by the government - 
though it has been allowed - as it aids in the spread of... well, foreign 
signals they obviously don't want people hearing in the case you 
(purposely) leave it behind.


I'm unaware of the power these jammers are running but a few are very 
high-powered. It's hard to know as they are naturally jamming local Seoul 
signals and other Korean skywave signals, so there is a fair bit of CCI 
sometimes and it's not as easy to null out AM signals that like to ride on 
top of one another unlike FM. If anyone has picked up these jammers on 
these frequencies across the Pacific, please let me know. On the other 
hand, you may be hearing these noises and not knowing the origins. Now you 
will.


All recordings are from the Seoul-Incheon metro area, which lies 
immediately on the North Korean border (north suburbs lie just a few miles 
from the border).


* * * * *

One of the more impressive jammers is the 75kHz-wide jammer on 711. It 
broadcasts from either the Haeju tower site or Anak tower site. The 
recording starts on 684 and goes up to 756 where 711 is the center of the 
jammer and the frequency it jams, 711 KBS 1 Radio Seoul at 500kw. The 
recording is taken on the coast 11 miles from the local tower site.


http://www.beaglebass.com/dx/external/Jammer_711_75kHz.MP3

The same jammer on 711 sounds different depending on the signal strength. 
The same is true for every jammer. They get highly distorted when under a 
signal or when weak, making it very difficult to tell the true pattern of 
the sound. Here are two examples of the 711 jammer which shows that:


When the jammer signal is heard strong enough, you can hear its true 
sound:


http://www.beaglebass.com/dx/external/Jammer_711_Strong.MP3

However, when the jammer is weaker and/or the local signal is too strong, 
it sounds more like a hum, disguising its full sound (which will also be 
heard with 1566 later):


http://www.beaglebass.com/dx/external/Jammer_711_Weak.MP3

This is the so-called "video game" jammer (my original observation of what 
it reminded me of, which Paul Walker also called the same thing in his own 
post later). This one is the KCBS flagship station, 819 in Pyongyang. I've 
recorded it instead on local 2850 to silence the annoying local jammer. 
This is the sign-off of KCBS and the sign-on of the jammer.


http://www.beaglebass.com/dx/external/Jammer_819.MP3

This is Pyongyang's jamming of 891 Busan, another KBS 1 Radio signal. They 
highly dislike KBS 1 Radio to the point where two signals are even jammed 
in downtown Kaesong (just outside the Seoul suburbs) on FM as well; hear 
that at the end of this posting. 891 Busan is from 194 miles away and 
250kw, but is not strong at all in Seoul. It's hard to hear clearly to 
start with and this jammer is actually quite weak and not extremely common 
to hear as the others.


http://www.beaglebass.com/dx/external/Jammer_891.MP3

Here's the jammer on 900, which is moderately common. The main signal is 
MBC Seoul under 10 miles away.


http://www.beaglebass.com/dx/external/Jammer_900.MP3

This one is only able to be heard atop the buildings in downtown Seoul, 
never at ground level (Henan, China can be heard behind it often at 
ground-level instead). This is local 972 at 1,500kw, 40 miles away and 
aiming north right at me nonetheless. You can null it out atop the 
buildings to the point you can hear the Pyongyang jammer behind it.


http://www.beaglebass.com/dx/external/Jammer_972.MP3

Another example of a hard-to-hear jammer, this is the jammer of local 
500kw 1134 south of Seoul, 21 miles away. It's almost certainly parallel 
to the 1467 and 1566 laser jammers and very likely from the Anak tower 
site. 

Re: [IRCA] TP 2 Dec Victoria version

[Chris Kadlec]

Nice catches!! You got really far inland on those, so I'd call that a big 
success. I'm impressed!!!


Your 972 would be Henan Economic Radio most likely, 100kw. It regularly is 
heard behind 1500kw 972 in Seoul and is a really hard signal to shake. I've 
IDed it a few times under there and 972 is under 40 miles away. Nothing else 
with enough power to hear on that frequency in Chinese, anywhere.


918 would be Shandong People's Radio, Jinan (200kw). It's a mess of echoes 
in Seoul because there are other 50 and 10kw affiliates on the same 
frequency.


819 I'd imagine is Pyongyang. I doubt you'd hear MBC (never say never I 
guess). But that Korean inflection is drastically different between north 
and south. The northern media dialect (which doesn't resemble normal speech 
patterns) is very distinct, but sometimes they also run more normal 
programming with normal speech patterns.


1377 is obviously CNR-1 in Zhengzhou //Beijing (the reason your 972 is even 
more obvious). That's far inland, but they get out strong into Seoul even at 
600kw. I wonder about the distance of that, geez! They're the only CNR-1 on 
the frequency as well and the frequency isn't busy at all in the region.


756 is CNR-1 Harbin, 100kw (or one of the many smaller CNR-1s, but doubtful 
given your other stations from up that way). 756 is almost exclusively owned 
by CNR-1. There's a 10kw station in Japan and no stations whatsoever on 756 
in Korea to hear.


1242 is obviously Nippon, Tokyo, 100kw as you likely suspect anyway. They 
play music and their unique cuckoo clock TOH ID sound. Nothing else to hear 
on there and 1242 in Korea recently went on super-low power. At 40 miles, 
you can barely hear the thing anymore whereas it used to pummel Tokyo, but 
no more.


All the others I'm sure you obviously know, such as the two Changchun 
signals (981, 1017) and Beijing. Anything else would be mere speculation on 
my part as you obviously have a fair number of 10kw signals in there that 
you got.

pretty darn good audio (all of it understandable by a native speaker,
at least briefly):

594 JOAK Japanese man in Japanese 1505UT
747 JOIB man in Japanese //774 (much weaker) 1510UT
972 HLAZ man in Korean 1503UT, had been bothered by a Chinese speaker
a minute or two earlier.
1566 HLAZ choral music 1539UT

Reasonable audio  at  times during the period (much of it
understandable by a native speaker, though often battling w/splash or 
noise):


639 CNR1 man in Chinese, one low pip, one high pip, Beijing time
check 1430UT, news sounder etc.
981 CNR1 woman in Chinese 1508UT, ID'd earlier by parallels
1017 CRI woman in Korean 1502UT




not so reasonable audio, occasional words or phrases in splash or
noise could be understood by a native speaker:

558 HLQH soft vocal music 1441UT  //603 which channel was actually
mostly Chinese talk by woman
603 HLSA soft vocal music 1431UT, //558 which was barely there just then
612 4QR fanfare, ABC news 1500UT
891 JOHK man in Japanese //594 1401UT
918 unID woman in Chinese 1506UT
945 CNR1 man in Chinese, news sounders 1530UT, best on north Flag
1206 Yanbian woman and man in Korean 1501UT
1287 JOHR man in Japanese 1524UT

Burbles in the splatter and noise (if lucky, language might be
guessed at by cadence of talk, or parallel established by changes in
talk or music)

702 2BL man talking //612 1507UT, plus someone else.
819 woman and man talking, Korean inflection 1504UT
837 JOQK man talking //891 1401UT
972 unID woman talking, Chinese inflection during dip in HLCA's signal 
1502UT

1143 woman talking, Chinese inflection 1503UT; something else there also
1242 pop music 1503UT
1323 CRI immense carrier, slightest traces of chimes and fanfare
1500UT, heck, those could have been from one of the other CRI
stations on that channel, they were so weak.   There were a couple of
other carriers on the channel, but no better than 20dB down
1377 CNR1 man talking, news sounders, //639 1502UT

Strongish het, no or "near imaginary" audio (either undermodulated or
ravaged by splatter) lots of near audio here

 621 756 855 936 1008  1035 1098 1107  1152 1179 1251 1278 1386 1422 1476

http://www.beaglebass.com/dx/external/Jammer_1134.MP3

This jammer is on most of the day, as well as the off-air hours of 1143 Radio 
Free Korea, which only broadcasts for skywave. I've recorded it here during the 
actual broadcast of RFK instead of during the off-air hours when it blocks 
Jilin Story Radio, which at 10kw is always behind RFK. RFK's tower is 6 miles 
from my location and is a relatively poor signal to begin

I read today that KMIA 1210 Auburn WA is dropping from 10 KW night to 220 watts 
night. Down here on the Oregon Coast that should really free up the frequency 
at night. I wonder when they will drop?
