LEM287 DXpedition to Lemmenjoki
December 27, 2009 - January
9, 2010
by Mika
Mäkeläinen
My second DXpedition of the season
was pretty successful, but very different from last
year at the same time. Chinese stations ruled the
AM band, and overall reception from Asia was very
good, a stark contrast to the 271th DXpedition in
Lemmenjoki a year earlier, when very few Far East
stations were heard. Limited propagation to the
Western Hemisphere was a bit disappointing considering
that in terms of solar weather all preconditions
for excellent reception did exist. Nevertheless,
we got several U.S. daytime-only stations, which
is always a cause for celebration.
On the road again |
After a traditional Christmas vacation
trip with family to my original hometown Tampere,
I scrambled to repack my car with all the necessary
DXpedition stuff. And there was a lot of it, even
though receivers nowadays take less space than ever.
It seems that external hard drives easily occupy
whatever space is left, and once again, I had more
of them than ever before. You know, you have to
be prepared for those elusive AM DX conditions of
the century - even if listening to the highlights
would take years.
I set out on Monday morning at 8:30 a.m. when it
was still dark, with the aim of reaching Lemmenjoki
late at night. I stopped briefly to refuel myself
and the car in Pyhäsalmi in Central Finland
on Highway 4, and when I got back on the road, it
was already getting dark. I had barely slept at
night, so just staying awake was a bit challenging,
and driving in light snow and slippery roads wasn't
exactly helpful. I saw a couple of trucks stuck
on an uphill stretch. Finally in Rovaniemi on the
Arctic Circle, where I shopped for groceries, I
just had to close my eyes and rest for half an hour
in the car. It made all the difference, and afterwards
it was rather easy to stay awake for the rest of
the journey. I finally arrived in Lemmenjoki around
12:30 a.m., after 16 hours and 1140 km (710 miles)
of traveling.
A sign in Pyhäsalmi
says it is still 287-890 kilometers to Lapland.
Exactly - it depends where in Lapland you're
traveling to! |
Adios Cuba, Nihao China
Fellow DXer Jari Ruohomäki from Oulu had arrived
in Lemmenjoki two days earlier, and left back home
three days earlier than me, but most of the DXpedition
we shared the cabin. On Jari's first two days of
listening stations from the Midwest and the Rockies
had come fairly well. After my arrival reception
of North American signals continued daily from around
2100 UTC to 1500 UTC, or even around the clock if
Alaskan stations are counted. Generally stations
were heard from Coast to Coast as long as a path
of darkness existed between us and the radio stations.
A few daytimers crowned our evenings. On Sunday,
January 3, 2010, reception conditions changed. In
terms of the U.S., nighttime conditions worsened
significantly, mostly Western stations were heard
during the daytime, and Canadians became even more
dominant than before.
Very few Cuban stations were logged, a major difference
from LEM271 a year earlier.
Also other Latin Americans were weak, and we only
got a fleeting taste of the remarkable midwinter
phenomenon of Brazilian and Argentine stations emerging
strong around 0700-0830 UTC. A nice exception was
the rise of Venezuelan and Colombian stations exceptionally
late on Wednesday, January 6. Greenland's national
radio KNR was hardly ever heard, although a year
ago it was a major nuisance covering interesting
trans-Atlantic frequencies. Arctic Radio on 1584
kHz, a special short-term station in Morokulien
in neighboring Sweden, was not heard at all in Lemmenjoki.

- snow mobiles are the way to get around here.

The most pleasant experience was the extremely
strong showing of Chinese stations throughout the
DXpedition, as well as Philippine stations on Friday,
January 8. Also a couple of shortwave catches, Radio
Symban from Australia on 2368.5 kHz and Radio San
Carlos from Costa Rica on 2859.82 kHz, were positive
surprises. Generally AM conditions kept us busy
enough without having to resort to shortwave, where
there would be very few stations to hunt anyway.
A more detailed description of the propagation conditions
on each day can be found in the end of this report.
We both used software-defined receivers, although
Jari also had one JRC NRD-535 for browsing the dial.
I worked with two Perseus receivers and Jari with
an array of SDR-14 and SDR-IQ receivers, enough
to cover the entire AM band. A total of 11 beverage
antennas, each about 1 kilometer in length, all
proved to be useful at one time or another.
Our DXing was very intensive and resulted in sleep
deprivation. The daily DX routine allowed slots
for sleep roughly at 1700-2030 UTC, and again in
the early morning at around 0300-0550 UTC. A couple
of books reserved for pastime in case of very poor
conditions remained untouched.
The coldest and coolest
place in Lapland |
Cold as in Alaska? You betcha!
As everyone knows, sauna is an integral part of
the Finnish lifestyle, and you sometimes hear people
bragging about how high temperatures their sauna
has reached. Well, our sauna was the coldest I have
ever been to - initially just 42 degrees Celsius,
roughly half of what Finns would consider normal
and a third of what the most ardent aficionados
can endure. After spending an hour in the sauna
it finally warmed to a bearable level.
The stove in our landlady's sauna is no longer
in the best possible shape. Still, the cabin itself
- which doesn't have a sauna - is in an even more
rundown condition. The floor is leaning to one edge,
and insulation is so poor that in addition to electric
radiators you need to keep burning wood in the stove
just to keep warm. Elementary, but serves the purpose.
And the weather forecast
for today, looks like it's gonna be a cold morning...
|
On arrival I noticed that the door handle had fallen
off from the outside. Previous dxpeditionists had
replaced it with a metal wire which you had to pull
to open the door. Then one day it broke off, the
door was pretty well stuck, and I was outside. Fortunately
this time around I wasn't visiting the outhouse
semi-naked, but appropriately dressed for the -27
degree temperature outside, as I was leaving to
get some more groceries. The nearest shop is a mere
40 kilometers away. When I returned, a neighbor
helped to fix the door temporarily with a spare
handle.
Lemmenjoki is a notoriously cold place. During
this DXpedition the lowest recorded temperature
was -38 degrees Celsius (-36 F), even though the
national record for this winter is so far "only"
-37 degrees. There are no official weather stations
of the Finnish Meteorological Institute anywhere
nearby, so these cold spells never make it to history
books. Officially, the lowest temperature ever recorded
in Finland is -51.5 degrees Celsius, but at the
same time the temperature in Lemmenjoki was -58
degrees Celsius (-72 F).

(information
collected by Jan Alvestad)
Here's a closer look at the propagation conditions
day by day. Jari reports on the first two days,
and I'm covering the rest:
Sunday, December 27
Jari: LEM287 is now on. I arrived yesterday evening
before 19 UTC. Having given some tulips to our 90-year-old
host Kristiina it was time set up the listening
post. I am not sure about the quality of the conditions
in the night because I had to concentrate on controlling
all the 6 SDRs and 1 NRD in a sensible way and sleeping
as well. There were Yankees all day long till 15
UTC. It seems that the most interesting moments
were before noon. I noticed KROE 930 and KID 590
"on the fly". Next I have to google which
one is broadcasting ESPN Deportes Radio on 1310.
Probably some bull***t from the west.

Monday, December 28
Jari: No morning Brazilians, no La Plata, no Mexicans
and not even high quality Yankees. Quite boring
all night and day long. Canadians and dominants
are booming and it is hard to be "at the right
time on the right frequency". Files of more
than 150 GB should contain some highlights. NRD
loggings: KBSU 730, KUGN 590, KDAL 610, KUBC 580.
The current outdoor temperature is only -15. And
the indoor temp has finally reached +20. That's
today's highlight so far. Yesterday evening it was
-31 and, of course, I was without electricity for
3 hours (17-20 UTC). But now everything is under
control, except that the conditions should be much
more directional and interesting.
Tuesday, December 29
Mika: I got my gear running just before midnight
UTC on Monday evening, when U.S. stations were audible
all across the AM band. Soon conditions covered
a wide area from Colombia and the Caribbean to the
entire North America. WMCA New York NY on 570 kHz
was one of the best catches of the night. North
American stations continued to dominate the dial
even late afternoon, when 930 KSDN and 1060 KGFX,
both from South Dakota, were logged around their
local sunrise. Otherwise there was little directionality
in conditions at any point. The new X-band Canadian
CJEU on 1670 kHz turned out to be an easy catch.
The first Asian stations were noticed around 0930
UTC, but conditions remained mediocre, and spread
over a huge area, so finding anything new is challenging.
A bunch of the most common Philippine stations (such
as 882, 1160.9 and 1314 kHz) were heard loud and
stable. Overall, decent, but not super. The huge
amount of recordings should however guarantee some
nice surprises. Early evening I was happy to hear
Radio Symban from Australia on 2368.5 kHz. The signal
was relatively strong considering that conditions
didn't really favor Australia. Afterwards I heard
from the station that the transmitter power at the
time of listening was 400 watts.

Sanomat did a large article "The decade
of the wires" at new year - without a word
about DXing. |
Wednesday, December 30
North American stations were heard all around the
AM dial by 2200-2300 UTC, but unfortunately the
usual suspects from Canada and the Upper Midwest
tended to dominate the channels. Overnight catches
included WEBC Duluth MN on 560 kHz. Signal strength
was initially very good but weakened a bit in the
wee hours. Hardly anything was heard from Latin
America overnight, and even in the morning reception
was sporadic. Only few Cubans were heard, but Radio
Rebelde still hung around way past 1000 UTC on 1180
kHz. The best time for North America was around
1200-1500 UTC, when also graveyard channels were
decent and many West Coast stations (notably 1290
KOUU) remained audible until 1600 UTC, past its
local sunrise. One of the best catches was KLBS
Los Banos CA on 1330 kHz. From the Eastern Hemisphere,
the first Asians were noted after 0900 UTC. Initially
many of the stations were from northern China, but
gradually conditions covered too wide an area to
make interesting catches - nevertheless, a better-than-average
day for Chinese stations.
Thursday, December 31
Our New Year's Eve began already around 2100 UTC
on Wednesday evening, when stations from Atlantic
Canada and the U.S. Northeast emerged from the noise.
Our best catches include CFSX Stephenville NF on
870 kHz and WHJJ Providence RI on 920 kHz, which
has become a fairly common station this season.
Afterwards relatively poor conditions on the AM
band drove me to shortwave, where Radio San Carlos
from Costa Rica was a neat surprise on 2859.82 kHz
(a second harmonic of 1430 kHz), heard the first
time I ever even tried for it, although without
a proper ID - which I got the following night. On
the Latin front it was also nice to catch Radio
Pachamama from Puno, Peru, on 849.90 kHz. In the
morning reception to all directions was below the
level of preceding days. North America improved
somewhat in the afternoon, and both KKIN Aitkin
MN and KSDN Aberdeen SD were identified on 930 kHz.
U.S. stations nearly vanished around 1400 UTC. A
few Mexicans were heard around midday, including
XEBBB Guadalajara JL on 1040 kHz. JOIF on 1413 kHz
marked the beginning of the Asian influx already
at 0840 UTC. The first Chinese stations were from
the northern part of the country, including Liaoning
PBS on 963 kHz, but later on typical pan-Asian conditions
ensued.

Friday, January 1, 2010
North American stations surfaced gradually around
2100-2200 UTC on Thursday evening, but signals remained
weaker than on the previous night. No new stations
were noted in real time, although it was interesting
to see that KGOW Bellaire TX had shifted from 1560
sharp to 1559.94 kHz. A few Brazilians and other
Latin Americans were heard as well, but conditions
remained below average. On a positive note, it was
neat to hear the New Year being welcomed in different
time zones around the world, and listen to ABBA's
"Happy New Year" for umpteen times. After
1000 UTC U.S. stations came in full force from Coast
to Coast, and many of them airing Coast to Coast
AM. In the afternoon conditions improved on the
upper half of the AM band, peaking at 1300-1400
UTC, with Mexicans joining the mix. One of the best
catches on the Western front was KROE Sheridan WY
on 930 kHz. Around midday we tentatively picked
up Tahiti on 738 kHz and Tonga on 1017 kHz.
Saturday, January 2
The first trans-Atlantic signals appeared by 2100
UTC, but conditions were poor. WRRD Waukesha WI
on 1510 kHz was identified by sheer luck, but otherwise
nothing to listen to - except on the other side
of the world, where Chinese stations came really
well around their local sunrise. North American
stations improved after 0100 UTC and grew stronger
in the morning, continuing past 1400 UTC. Signal
levels were good, but once again stations mixed
from too large an area. There were nevertheless
a couple of highlights, such as WRTO Chicago IL
on 1200 kHz and WRWH Cleveland GA on 1350 kHz. Chinese
stations blasted from 0900 UTC throughout the afternoon,
and the number of Japanese stations was higher than
on previous days. DZAS from the Philippines on 702
kHz was among the best catches heard in real time
from Asia.
Sunday, January 3
North American signals appeared at the same time
as before. Initially East Coast stations came fairly
well, but signals didn't improve to the level of
the previous night. Around 0300-0400 UTC there was
a change in the nature of conditions. Unlike all
previous nights, suddenly only U.S. West Coast stations
were heard, although with rather weak signals. Daybreak
was extremely poor to all directions. However, by
midday U.S. stations emerged again, and instead
of an overwhelming mess on each frequency, stations
were often heard only one at a time. This would
be a good recipe for surprises, but unfortunately
regular Canadians tended to dominate the band also
today. Asian stations became audible later than
on previous days, but improved fast, and overall
conditions to China were rather good, and there
were more Japanese on the dial than on previous
days. There are lots of recorded IDs to be found.
In the early evening we got our first taste of Alaska
(aside from the regulars heard daily), and identified
for example KMBQ in Palintown AK on 1430 kHz.

Monday, January 4
East Coast stations followed cheerleader WEGP (1390
kHz), but after a moderately good start, most of
the night was lousy. Weak signals were heard here
and there, with a slight emphasis on the Canadian
Prairie and the Pacific Northwest by the morning.
In the morning hours the AM band had the marks of
some kind of magnetic disturbance: there was a strong
hiss all across the band, and instead of the usual
mix, few stations. However, this allowed the mumble
of the graveyard frequencies to give way to decent
signals. For the first time during this DXpedition,
local channels had readable signals already around
0700-0800 UTC. During the day conditions were confined
to the Western half of North America. Alaskan and
Hawaiian stations were louder than on any previous
day, but we didn't find anything new. In the afternoon
reception of stations from the West cooled around
1400 UTC, earlier than normally. Conditions to Asia
were good. Stations faded in later and faded out
sooner than normally, but signals were very strong,
focusing again on China, with a very brief opening
to Thailand just before Europeans finally took over
the band.
Tuesday, January 5
Brazilian stations were the first to appear on
the dial around 2130 UTC on Monday evening, followed
a bit later by North Americans. The few North American
stations that made more than a brief appearance
were mostly from Minnesota and the Dakotas, and
of course the Canadian Prairie, which have tended
to dominate the frequencies during our DXpedition.
Conditions to Latin America were similarly poor
and sporadic, and overnight listening reminded me
of typical conditions during less favorable parts
of the solar cycle. However, in the morning at 0730-0800
UTC we got our first morning opening to Brazil and
Argentina. This was modest compared to last year,
but a start anyway. During the day North American
stations were focused west of the Great Lakes, with
Canadians typically dominating. However, graveyard
channels were open, so we expect some nice surprises
later on. Signals deteriorated rapidly after 1400
UTC. Asian stations emerged early and strong. There
were even more Japanese than before (such as JOHG
Kagoshima via Naze, Okinawa, on 792 kHz), but of
course usually not during the few time slots when
identifying NHK's local outlets would have been
possible.

Wednesday,
January 6
Trailblazer WEGP was heard after 2030 UTC, but
only some Canadians appeared after 2100 UTC. Signals
began to improve relatively late, around 2300 UTC,
and included also U.S. stations, especially Upper
Midwest. Right after midnight we got a nice opening
to Venezuela and Puerto Rico, which continued to
the morning when nothing much else was audible.
Around daybreak we had excellent conditions to Venezuela
and Colombia, lasting past 1000 UTC, which we had
never experienced before. After the Latinos lost
steam, the U.S. East Coast came to the rescue, but
in the afternoon conditions to North America were
poorer than on any previous day, and the last signals
faded away around 1400 UTC. From Asia it was Chinese,
Chinese and then some more Chinese stations. I predict
a stunning number of station identifications that
need native help in interpretation.
Thursday, January 7
A few weak signals from North America emerged at
East Coast sunset around 2100-2200 UTC and improved
somewhat around midnight UTC. In general the night
was very poor to all directions. Some Brazilian
and Argentine stations were heard in the morning
after 0700 UTC, until as long as 0830, when Radio
Rio Cuarto on 1010 kHz from Argentina began its
broadcast day. Reception from North America was
miserable even during the daytime, and a bunch of
stations emerged from the background noise level
only when total darkness fell around 1330 UTC -
so much like the solar maximum years. Asia on the
contrary was again very good with loads of Chinese
stations heard for hours. Also more Philippine stations
than before, but at least in real time I didn't
notice any personal new ones. DWXI dominated 1314
kHz most of the afternoon. So far the best station
of the afternoon is HLCX Jeonju from Korea on 855
kHz.
Friday, January 8
Stations from Brazil, Venezuela and the East Coast
of North America all began to make their way here
at the same time, around 2200 UTC. However, conditions
to all directions were poor, and so I decided to
sleep most of the night, for a change. Some Latin
Americans struggled to be heard in the morning,
but North American stations were relatively strong
for a couple of hours. Then signals remained barely
above noise level for most of the afternoon, before
a slight increase of Northwestern stations around
1330 UTC, and disappearing afterwards. Once again
the Eastern front was much more interesting. Conditions
to the Philippines were extremely good around 1030-1300
UTC, and although I already have almost 50 Philippine
stations, I found at least a couple of new ones
(DYEZ 684 kHz and DYSI 1323 kHz). Many Philippine
stations are on split frequencies, which you can
find later in the log. The Chinese were also very
strong, and as conditions were more towards the
Southern part of the country, I expect some nice
surprises on recordings. European stations were
remarkably strong all day, even midday local time.
Saturday, January 9
The last night began with Atlantic Canada, Ontario
and some East Coast stations around 2100 UTC. North
American signals improved a bit after 2300 UTC as
the sun set from Minnesota to Alberta, indicating
a very familiar focus of propagation. In the morning
North America was strong, easily overwhelming Latin
American stations. Before midday signals from Alberta
and the Pacific Northwest were more powerful than
I have ever heard before, and a lot of Alaskans
were heard like local stations. Unfortunately after
midday it was time to pull the plug, and head home.
The LEM288 crew, Jussi Suokas and Jopi Nyman, arrived
after 1000 UTC on Saturday. I briefed them on the
conditions and packed my stuff. For the first time
I did some DXing even during the return trip. I
enjoyed Jari's hospitality - including a hot enough
sauna - at his summer cottage in Muhos, where I
stayed overnight and recorded some 1.5 hours of
Perseus files at sunrise. It was great to be able
to divide the return trip into two days, as I was
really tired from all the DXing. I finally made
it home early Sunday evening, after driving a total
of 2520 kilometers (1566 miles), back and forth
between Vantaa and Lapland. But I plan to be back
in Lemmenjoki in eight weeks time for a third round,
which would make this season a personal record of
northern exposure.
