Trans-Pacific MW and Tropical Band Loggings
 

It's been a pleasant surprise to find trans-Pacific mediumwave signals
making it through the RF jungle this week. I didn't think I could hear
overseas mediumwave at home near my Seattle/Tacoma area powerhouses, but I'm
happy to have been proven wrong! However, the tremendous boost in the noise
and splatter level when locals increase their power at sunrise precludes any
DXing past 1330 these days.

The best antenna by far this week was the NW Beverage. I found no hints of
Down Under reception, as conditions were dominated by a northwesterly path
to Asia.

------------------------------------------

MEDIUMWAVE

594 JAPAN JOAK Tokyo NHK1, Sep 5 1250 - Strong signal with male announcer in
Japanese; 'NHK' network ID in middle of traditional Japanese music at 1254
before fading. Noted with audio at 1330 recheck. (Atkins-WA)

657 UNIDENTIFIED , Sep 4 1302 - Weak audio by male in unidentified language.
Most likely the powerful North Korean station on this frequency, given the
predominance of Asian MW DX this week. (Atkins-WA)

666 JAPAN JOBK Osaka NHK1, Sep 5 1318 - I noted a weak signal of Japanese
language by male on this frequency at 1318, but it never improved. Likely
JOBK, the only Japanese outlet on 666. (Atkins-WA)

693 JAPAN JOAB Tokyo NHK2, Sep 5 1258 - Japanese audio with male announcer
heard at tune-in; time pips at 1300 and into news items. Fair to good at
peaks. (Atkins-WA)

738 UNIDENTIFIED , Sep 5 1309 - Very weak signal in unidentified language;
kept checking back but signal never improved. Best reception on NW Beverage,
so possibly the strong Korean HLKG, given the Asian propagation and other
Koreans audible. (Atkins-WA)

747 JAPAN JOIB Sapporo NHK2, Sep 4 1310 - Weak audio in Japanese by male and
female announcers. Also heard August 5 at a better level. (Atkins-WA)

774 JAPAN JOUB Akita NHK2, Sep 4 1317 - Fair audio by female announcer in
Japanese; signal slowly drifted downward into the noise. (Atkins-WA)

972 SOUTH KOREA HLCA Dangjin, Sep 5 1314 - Very good audio during fade-ups
with man and woman announcers in Korean; orchestral music during later
recheck at 1325. (Atkins-WA)

1053 JAPAN JOAR Nagoya, Sep 5 1314 - This was coming in at a good level with
male and female announcers' bubbly talk in Japanese, until the Korean jammer
on the frequency rose in strength to make reception tougher. (Atkins-WA)

1062 UNIDENTIFIED , Sep 5 1321 - Faint audio heard on 1062, possibly Korean.
If so, this may have been HLKQ in Cheongju (50 kw). (Atkins-WA)

1134 JAPAN JOQR Tokyo, Sep 4 1320 - Fair signal of man and woman announcers
in Japanese, and bouncy Japanese pop music before fading at 1325. Also noted
on August 5th with audio. (Atkins-WA)

1575 THAILAND VOA Ayutthaya, Sep 5 1323 - Female announcer in a SE Asian
language such as Vietnamese or Burmese. Presumed log, but John Bryant to the
north of me has been hearing VOA on this frequency at good levels this week,
so likely them. (Atkins-WA)

----------------------------------------------

SHORTWAVE

CHINA 3900, 1331-1400, Hulun Buir PBS, Hailar, Nei Menggu Sep 3 Tentative.
Weak reception of man and woman announcers in Chinese, with Chinese flute
and vocals at 1335. Back to male in Chinese 1336, and buried by noise
shortly thereafter. (Atkins-WA)

INDONESIA 4604.9, 1326-1458*, RRI Serui Sep 4 Caught tail end of RRI network
broadcast, with RRI promo and announcements leading up to 'RRI Serui' ID by
male, 'Waktu Timur' time check, other announcements, and into very nice lagu
hiburan music. ID again at 1336. Excellent, pounding signal at tune-in; best
ever heard. Signal only weakening slightly past local sunrise. Low studio
modulation ID by male and voice-over steel guitar type instrument at 1454;
Love Ambon tune at 1455 (slightly upbeat, peppy version I've never heard
before), and announcer with ID, time check, frequency, and announcements
1456. At 1458* Love Ambon ended with Serui sign-off (1-1/2 hours past local
SR). Also heard at great levels on August 5. Can Serui really be just 500
watts? Sounds more like 10 kw. (Atkins-WA)

NEW ZEALAND 3935, 1314-1319, ZLXA Levin Sep 6 This station continues at
better than usual levels, as noted a week ago and as also reported by Walt
Salmaniw. Two men in a panel discussion in English at 1314; fair signal.
(Atkins-WA)

SOUTH AFRICA 3255, 0416-0420, SABC Meyerton Sep 2 BBC World Service news or
commentary by man, with discussion about US Bush adminstration's dealings
with Mexico, and into business news 0420. Fair signal at Meyerton sunrise,
and parallel to 5975. (Atkins-WA)

SOUTH AFRICA 3320, 0432-0438, R. Sonder Grense Sep 2 Tentative. Weak signal
of what seemed to be Afrikaans lang. by male. Ute QRM on frequency also,
disturbing the copy of Sonder Grense. Fading signal just past Meyerton
sunrise. (Atkins-WA)

Thanks for the logs! Those are enviable... we who live in the north-central
US (Minnesota) do not usually receive the nice Trans-Pacific MW or even SW
stuff that you folks do in the Pacific Northwest. However, I have been
focusing on MW this past weekend, and I have noticed a big jump in catchable
signals here in MN. I've logged quite a few stations that weren't coming in
to my location at all even last week. I am usually sleeping during the wee
hours, when the pursuit of MW DX is most fruitful, but even at 10:00 pm CDT,
I was getting stations from 2,000 miles hence.

Have fun!

Hi Jackie,

I noticed the Boulder mid-latitude "K" Index had been low for a few days
straight. When coupled with relatively low solar flux numbers, this very
often indicates good mediumwave and lower shortwave conditions.

I suppose if I had tuned some of the domestic 10 kHz channels I might have
heard a number of Alaskan stations, which are moderately difficult from
Washington State (along with Hawaii). But with the foreign stations coming
in, it was an easy decision to try for the "splits".

These stations I logged from Japan and Korea on mediumwave are common
catches during my DXpedition trips to the WA coast (usually to the small
community of Grayland), but this is the first time I've had much success
inland and near my mediumwave locals. It takes really good receivers and
antennas to pull in the (usually) weaker trans-Pacific MW DX amongst the
powerful stateside signals.

It can be tough to roll out of bed early enough to catch the DX, though!

Good Listening,

Guy

Congratulations and well done on some superb logs as usual, especially from
suburban Puyallup.

RRI Serui is interesting. I see that it is now moved from 4606.6 to 4605! -
I think reception in U.S. is favoured by the fact that the Serui TX has the
large mass of Irian Jaya mainland behind it and the high mountains. In my
empirical experience this would favour transmission to your QTH as some of
the transmitted signal would bounce off the mountains in your direction.
Received here in Montagu at 2100 utc, bang on local Serui sunrise. Very
faint though and confirms it's 500 watt power. Only managed a very faint RRI
"Radio Republika Indonesia" ID. Signal was barely readable and only came in
for about ten minutes.

OTOH I received RRI Fak Fak also at 2100 utc booming in quite clear with
excellent ID's on 4790 Khz. According to my theory Fak Fak is located on a
large bay with its outlook pointing directly to South Africa and mountains
behind the TX favouring reception in my area. This is also confirmed by the
fact that the signal is so strong here that it gives the impression that the
TX power is much more than the listed 1 Kw, but bear in mind that it is not
received in the U.S. at all.

Both Serui and Fak Fak were received at 2100 utc on 040906
They are both equidistant from Puyallup and Montagu - some 7,500 miles.

Fak Fak signal still holding up well here, SCI (Song of the Cocoanut Isles) at 1200,
mentions of Indonesia, then into presumed news, and the ocean radar (swisher), has
faded a bit. Like a lot of stations, the voice modulation seems a bit low, but the
music comes through quite well.

One of the better Indo's on the band this morning.

Steve, I congratulate you on getting RRI Fak Fak - I'm sure it doesn't come
in everyday in Holland Michigan.
Okay, I have not seen Fak Fak logged recently in the U.S. but have seen
several logs for RRI Serui, hence my comment.
Also, Guy Atkins in Puyallup, an extremely experienced DXer did not log Fak
Fak alongside his Serui log, although he was sure to have tried for it.

You have mentioned befo

but I beg to differ with your opinion. Here in Montagu, my QTH is surrounded
by high mountains and long distance DX comes in very rarely compared with
say a coastal site or a location on a flat plain. I'm not saying it NEVER
comes in, because, of course, my logs show that it does, but that is
occasionally. OTOH if I go on a DXpedition to the coast, then the very long
distance DX come's in everyday very easily.

It has also been written about in professional radio books and by
experienced DXers that long distance DX is very "low angle", which confirms
my own experience that high hills and/or mountains blocks out some of the
exotic long distance DX signals.

I have been on very many DXpeditions to a wide variety of locations and have
formed the opinion that better DX results are obtained if you are in a
"bowl" with its opening out towards the path of the TX site you are trying
for. This is even more enhanced at the coast if you are in a bay backed by
hills or mountains, and the mouth of the bay opens out towards your intended
target area. Magical results can be obtained under those circumstances.

Lastly, I receive more far distant DX from areas that have an open path to
my QTH, whereas getting Peru from over the Andes is a very rare occurrence.
Hence my opinion that mountains block long distance low angle DX signals.

Hi John & dxAce,

I didn't try for Fak Fak when I logged Serui because I was concentrating on
trans-Pacific MW last week. I was just briefly checking a few of the weaker
Indonesian frequencies, like Manggarai on 2960 and Serui.

I note in my logs that I last heard Fak Fak on July 9th at a Grayland
DXpedition. Here's the log:

INDONESIA 4790, 1233-1313, RRI Fak Fak Jul 9 Soft lagu romantik tunes in
Indonesian, continuous from 1233 tune-in. Powerhouse signal level, but some
swisher QRM. No break or announcers at top of hour. Male announcer with ID
at 1310, and back into music. (Atkins-WA)

Regarding Serui's frequency, John, I've noted them on 4604.9v lately.
However, back at the end of August they were 4606.5.

In my opinion, Steve and John's reception of Serui is more impressive than
mine, given your topography and QTH, local noise sources, and antenna
limitations you may have. Although my DXing in Puyallup is in the RF
"shadow" of strong Seattle/Tacoma broadcasters, my reception is enhanced by:

-Kiwa BCB filter + extension filter for shortwave DXing (*really* helps the
RF blocking/desense from the local MW powerhouses)
-underground AC power mains for about 1/2-mile radius from here
-2 Beverage antennas, one "aimed" right at PNG/Irian Jaya
-no horizon blockage
-although I'm about 90 miles inland from the ocean, it's a mostly water path
from here to my favorite targets

Ya wanna talk tough DX targets from my location? All of Latin America (not
really a region of interest for me though) and Africa (which I'd love to
hear more often). African DX is loads of fun on morning longpath, with a
southwest Beverage antenna at the coast, around local sunrise. I've had the
strongest African signals on the morning longpath. BTW, mid-winter is best
for this.

Guy

Hi Guy,
You raise two points of interest.
One is that it is a fairly regular feature of S. African DXing for us to get
N. American MW stations, but it seems very difficult indeed for U.S. MW
DXer's to get the 100 Kw powerhouse omnidirectional TX's that we have here
in S. Africa in the U.S.A. Even Mark Connelly on the East coast and a
Canadian DXer up in Nova Scotia seem to have great difficulty.

The Canadian fellow achieved what for me must be the ultimate DX catch in
Nova Scotia - he claims to have got our 100 Kw R. 702. Now this TX has a
very effective antenna system beamed only to the South West, so the signal
to him could only have been long path - an astounding 17,000 miles away. If
you go just North of the 702 TX you will get BBC on 702 from Europe. Since
this path lies near Grayland, you might like to try for that when conditions
are next good???

Also, I have a good friend in France who DX's NDB beacons on LW and he has
also commented that European DXer's seem to get more N. American catches
than Americans getting Europe. Go figure.......

Second, your experience is that your best most exotic DX is caught in mid
winter. My experience down here is that the equinox - around 21st March and
21st September have given me markedly better results than any other time.
That applies both to my home QTH and various DXpeditions.

There are some other anomalies too - Although getting U.S. East coast and
Brazil here are fairly common, getting Mexico and Central America is so rare
as to be an occasion to break out a bottle of champagne if you ever get
one..... Also, even though Brazilian catches are common here, right down to
the very South of the country, Argentina, right next door, hardly ever comes
in. I really have no logical explanation for this.

The CODAR transmitters are causing some serious QRM on the tropical
bands in the range 4500-5000/Khz. I've emailed some of the operators,
which are usually universities, to remind them that their transmitters
are disrupting certain international broadcasts. However the FCC
encouraged them to use these frequencies because shortwave listeners are
at the bottom of the barrel when it comes to interference from licensed
stations such as CODAR. The current FCC chairman doesn't seem to care
about the possible interference from the proposed BPL systems, so I
doubt he's concerned about CODAR interference to shortwave listeners.

I get interference on two bands. The high end of 25 meters and the low
end of 22 meters. About as annoying as the Bryant interference on RRS.

I am getting what I believe to be CODAR on two areas of the dial, centered on
these freqs.: 4546 and 4800 kHz. As I am located on Long Island, NY I expect
that these are originating from stations on the New Jersey shore.
