International Broadcasters Know DCC
by Ernie Franke
on 10.12.2011
http://www.rwonline.com/article/international-broadcasters-know-dcc/24576
The author, WA2EWT, is a broadcast consultant in St. Petersburg, Fla.
The FCC has formally approved a "green" technique for AM radio stations that
want to
reduce their operating costs. The technique is known as Modulation Dependent
Carrier
Level, or MDCL. Public notice was issued on Sept. 13, extending what had been
an
experimental program in Alaska to all U.S. AM stations.
International broadcasters have been familiar with the concept for many years
under the
name of Dynamic Carrier Control. The purpose of this article is to explain to
U.S. AM stations
a technology already familiar to their colleagues abroad.
With escalating power bills, controlling electricity usage is especially
important to the
international broadcaster. Dynamic Carrier Control, offering significant
savings in power bills
for high-power broadcast transmitters, was proposed more than 75 years ago. It
took the
power of the integrated circuit digital signal processor (DSP) and pulse-step
modulation
(PSM) to bring it to fruition.
Power savings are impressive when DCC is added to 100, 250 and 500 kW
transmitters.
Today, all modern super-power (output power greater than or equal to 100 kW)
shortwave,
and most medium-wave (AM band) transmitters, incorporate DCC capability. Total
power
consumption typically is reduced by 15 to 30 percent, and the effects are
virtually
undetectable to the listening audience.
As a benchmark, the average household in the U.S. consumes about 11,000
kilowatt-hours
of electricity each year. Assuming an average power savings of 25 percent with
DCC, a
single modern 250 kW transmitter, operated 12 hours per day, saves 342,000
kilowatt-hours
per year, or the equivalent of powering 30 average homes.
If we multiply this by the over 1,000 shortwave, super-power transmitters
positioned around
the world, we save enough electrical energy to power over 30,000 homes, a small
city.
The AM modulator impresses the program onto the high-frequency radio wave.
BACKGROUND ON AMPLITUDE MODULATION
Amplitude modulation occurs when a voice or music signal?s varying voltage (fm)
is applied to
a carrier frequency (fC). The resultant AM signal consists of the carrier
frequency, plus upper
and lower sidebands, known as double sideband amplitude modulation (DSB-AM),
more
commonly referred to as plain AM.
When a carrier is amplitude-modulated, only one-third of the total RF power is
contained in
the information-bearing sidebands. The other two-thirds of the RF output power
is contained
in the carrier, which does not contribute to the transfer of information. The
intelligence is in
the sidebands, and the carrier is aptly named for its purpose of merely
carrying the
modulation.
With a complex modulating signal, such as voice or music, the sidebands
generally contain
only 20 to 25 percent of the overall signal power; thus the carrier consumes 75
to 80 percent
of the total output power, making AM a very inefficient mode of transmission.
This raises the question: "How can the transmitted waveform be modified to
reduce power
without reducing received quality in simple AM receivers?"
WHAT DOES THE CARRIER DO FOR US?
The carrier in any AM system has two functions: to translate the information
signal to a higher
frequency that is suitable for transmission and to suppress static noise and
interference
during silent intervals in the program. When the amplitude of the audio signal
is significantly
less than that required for 100 percent modulation, it is possible to save on
the power
consumption of the transmitter by reducing the amplitude of the carrier,
without affecting
demodulation of the sidebands. Power savings of 15 to 30 percent (depending on
program
material) are feasible if carrier power is reduced 3 to 6 dB (carrier reduced
one-half to one-
fourth) of the rated output power when modulation is low, with little or no
effect on reception
of the signal. DCC is designed to keep the carrier at sufficient amplitude to
achieve 100
percent modulation, even during the low-level portions of the audio program.
WHAT IS DCC?
The spectrum of AM signal shows the wasteful carrier power compared to the
information-
bearing sideband power.
Traditionally, AM systems have provided a fixed carrier level and applied
modulation up to
100 percent (or +125 percent positive). Using DCC, during periods of low or no
modulation,
power consumption can be significantly lowered by automatically reducing the
carrier level
and restoring the carrier level when modulation later increases.
The transmitter is adjusted for full carrier power output when the audio input
appears at 100
percent modulation. If the audio input level falls, the carrier level will
dynamically adjust itself
to maintain modulation at 100 percent. If modulation is totally removed, the
carrier level will
fall to a pre-selected minimum level (-3 dB to -6 dB). Typically a front-panel
switch or remote
control offers selectable levels and types (different transfer curves) of DCC.
With a typical 0.1
ms attack and 200 ms release time, DCC retains the ability to modulate to
positive 125
percent as we do now. At +125 percent modulation, the carrier remains at the
same level
corresponding to 100 percent modulation.
ORIGIN OF DCC
This amplitude modulation energy-saving mode was devised in the late 1930s. DCC
was not
implemented in transmitter designs until the 1980s, because of the complexities
of the
control circuitry. If we journey back in time to the 1930s to the village of
Gliesmarode in
Germany, we find the first trace of DCC with Professor Pungs, who was involved
in the
development of broadcasting technology. His system was known as "HAPUG"
Modulationsverfahren, incorporating the last name of each of the three
inventors: Harbich,
Pungs and Gerth. This system never made it beyond the experimental stage, due
to a lack of
computing and processing technology.
PULSE STEP MODULATION
The transfer function between the program audio and the actual level of the
carrier has
evolved to a curve that reduces the carrier power by a factor of four in the
mid-volume range,
but retains half-power at low audio moments.
The advent of PSM in the 1980s and DSPs in the 1990s allowed the implementation
of DCC
in all modern, high-power transmitters today. Using signal processing, we can
readily break
the modulation voltage waveform into a large number of steps. These small
increments are
used to turn a series of switches on or off. Thus modulation losses are now
reduced to very
low switching losses, increasing the efficiency of the modulator itself to
better than 95
percent.
The modulator typically consists of 48 series-connected modules, mimicking the
sampling
levels, which are switched into and out of operation to superimpose high-level
audio onto the
high-voltage DC anode (plate). The switching is accomplished with insulated
gate bipolar
transistors (IGBTs). A low-pass filter follows the series-connected modules,
which removes
the switching signals and allows the DC and audio signals to pass to the RF
amplifier. To
further refine the linearity, each power supply step is pulse-width modulated,
creating a
smooth transition from one step to the next.
PROGRAMMING TYPE AFFECTS POWER SAVINGS
As might be expected, actual power saving over that of non-DCC usage is highly
affected by
audio program content, with talk programs giving more power-saving than most
music
programming. Even the short blank spaces between spoken words allow the carrier
to be
reduced in conjunction with the decrease in modulation power.
Popular music programming dwells longer at modulation peaks, as evidenced by
the higher
degree of modulation index. Audio processing, which artificially increases the
average level
of modulation, tends to reduce power savings and increases the total power
consumption.
Tests using processed music programs consistently produced a power saving of 18
percent,
whereas talk programs produced power-savings in excess of 22 percent.
DOES DCC AFFECT THE LISTENERS?
In AM transmission systems, the signal-to-noise ratio (SNR) is largely
determined by
sideband power, not by carrier power. Thus, if an AM transmitter is modulated
at 50 percent,
a listener will have to turn the volume up 6 dB (x4) to get the same loudness
as a transmitter
modulated at 100 percent, consequently bringing up the background noise level
by the same
amount. If the carrier level of the same transmitter is lowered to obtain 100
percent
modulation, no change in sideband power will occur. A receiver?s automatic gain
control
(AGC) circuitry will bring the volume up much as a volume control does, and
background
static noise will also increase by the same amount. Thus the SNR remains
constant.
The advent of the digital signal processor (DSP) and the solid-state pulse-step
modulator
(PSM) have allowed DCC to emerge as a `green? technology.
When folks seriously discuss the quality of the received signal over audio,
they are most
likely talking about local AM or FM, where small imperfections are readily
noticed. The quality
of audio over shortwave or international medium-wave is inherently low, due to
atmospherics,
fading and noise. Laboratory tests on subjective listening quality using DCC,
even with co-
channel interference, showed no degradation.
Today, with so many Web-controlled, remote monitoring receivers, it is easy for
a
broadcaster to access their signal audio via the Internet. This allows the
broadcaster to
monitor their signal and make their own assessment of DCC under real-world
propagation
effects when transmitting to remote areas on shortwave. DCC tends to have
little effect on
listener perception because of slow receiver AGC. Experience has shown that
when running
a transmitter with DCC, response time is best set to fast attack/slow decay
(0.1 ms attack /
200 ms release) and carrier suppression, with no modulation, is set to -6 dB
for first-hop
targets and -3 dB for third-hop targets.
HOW DOES DCC AFFECT THE TRANSMITTER?
DCC extends the life of transmitter components because the transmitter operates
below its
design capability. One first notices that the power amplifier (PA) current
meter now starts to
wiggle with DCC energized. PA current will decrease with low-level audio as the
carrier level
is dynamically in accordance with the average modulation. Without DCC, the
majority of PA
current was needed just to produce the large constant-amplitude carrier power.
This variable power-line loading can cause audio modulation on the AC mains if
the power
lines are exceptionally long to the broadcast station. This is especially true
at large
transmitting centers, where two or more transmitters are simultaneously
broadcasting over
different bands, but using the same audio program. When powered by diesel
generators,
feedback control circuitry in the generators must be modified to handle these
increased load
swings on the AC power line.
WHO OFFERS DCC?
DCC?s effectiveness and acceptance by broadcasters is indicated by the fact
that all of the
super-power shortwave transmitter manufacturers - Continental Electronics in
Dallas, RIZ-
Transmitters in Croatia, Thomson Broadcast & Multimedia in Switzerland and
Nautel in
U.S./Canada - offer it as built-in or optional. Nautel has long offered DCC on
its NX series
of high-power medium-wave models. Harris Corp. offers DCC in its line of
high-power AM
transmitters.
The addition of DCC can pay for itself in as little as a few months, based on
the broadcast
power level and the price of oil. Transmitters more than 30 years old evidenced
an overall
efficiency of only 70 percent. With the use of switch-mode Class D and
pulse-step
modulation, the overall (AC power-to-RF power) efficiency has improved to
nearly 80 percent
for high-power shortwave and nearly 90 percent for high-power medium-wave
transmitters.
FOLLOW THE MONEY TRAIL
DCC?s appearance can be linked to NATO nations trying to save energy as a
result of the
ripple effects of OPEC-related oil supply crises. Eastern European
manufacturers of
shortwave transmitters never adopted DCC because Russia, in particular, had no
energy
crises due to its abundant supply of oil.
International broadcasters are indeed interested in "going green," and even
more so in the
future as power bills continue to esculate. Not only do all the manufacturers
of high-power
transmitters offer DCC, but all the broadcasters use it to help contain
expenses. DCC was
pioneered by the broadcasting giant British Broadcasting Corp. (BBC) and AEG
Telefunken
in the late 1980s.
As the cost of electricity steadily increased, others such as Voice of America
(VOA), Trans
World Radio (TWR), HCJB (Voice of the Andes), Radio France Internationale
(RFI),
Deutsche Welle (DW), Radio Canada International (RCI), Far East Broadcasting
Co. (FEBC),
Australian Broadcasting Corp. (ABC Radio Australia), Radio New Zealand (RNZ)
and Radio
Netherlands Worldwide (RNW) quickly joined the fray. As a simple matter of
economics, it is
to be expected other broadcasters will add to the numbers, as they are able to
make the
switch.
In April 2011, the FCC authorized the use of DCC on non-commercial AM stations
in Alaska
as long as notification was given to the commission. The high cost of
electricity in the state
was a factor in the decision to allow stations to use DCC experimentally.Power
reductions of
30 to 35 percent were reported, with no deterioration of received sound and no
complaints
about reception from listeners.
The experimental operation appears to have been a success, confirmed by the
recent FCC
action to allow DCC for all U.S. AM stations.

Peculiar Russian shortwave numbers station is an unlikely internet star
Posted on October 12, 2011 by Paul Riismandel
http://www.radiosurvivor.com/2011/10/12/peculiar-russian-shortwave-numbers-station-is-an-
unlikely-internet-star/
Page from the UVB-76 station log dated 2005.
Anyone who has spent some quality time scanning the shortwave radio bands has
likely
come upon what are known as numbers stations. To the uninitiated the stations
air what the
name describes, someone reading of a sequence of numbers. They can be in any
language,
but most commonly are in English, Spanish or Russian. They are believed to
transmit secret
coded messages to agents overseas, but nobody really knows for sure what
they?re purpose
is.
The Russian shortwave station UVB-76 is a peculiar example of a numbers
station, mostly
because it is known to air a wide variety of noises and sounds besides numbers.
Thanks to
an Estonian blogger (full disclosure: I?m half Estonian) the Russian station
has become
somewhat of an internet sensation. Or at least more of a sensation than most
shortwave
stations that aren?t streamed on the internet.
The October issue of Wired magazine features an article on the station and the
mystery
surrounding it, as well as an interview with blogger and tech entrepreneur
Andrus Aaslaid
who decided to start streaming the station.
I can really identify with Aaslaid when he tells Wired,
"I?ve spent nights just randomly browsing and sometimes getting really,
really drunk,"
Aaslaid says. (His drink of choice is Aberlour A?bunadh, a single-malt Scotch.)
"In the era of
the Internet and corporations, people?s lives are so well planned and
predictable," he says.
"In some ways, UVB-76 represents the good kind of unpredictability and
mystery." ...
"Imagine somebody with a Morse key or a reel-to-reel tape deck in the
middle of the
Namibia desert, running a shortwave transmitter off a diesel generator and
sending music or
messages toward the ionosphere. In the middle of the night, it does not get any
more spiritual
than that."
Reading that makes me want to stay up late with the lights off, wearing
headphones,
scanning the shortwave dial.
Damn, I?ve got work in the morning.
More on point, on Tuesday Aaslaid posted that supposed pages from a logbook
used at the
station in 2005 have surfaced in a Russian radio online forum. It even includes
a mention of
the station?s guard dog, noted to be on duty at 18:30 on October 4.

Digital Radio and the Future of Shortwave
by James Careless
on 10.16.2011
http://www.rwonline.com/article/digital-radio-and-the-future-of-shortwave/24599
Digital shortwave radio is no dream: It exists today. Right now,
foreign-service broadcasters
in Europe, Asia, Africa, Oceana and the Americas are providing regular digital
radio
broadcasts over shortwave, using the DRM30 transmission standard.
"The Digital Radio Mondiale AM solution operates worldwide," said Ruxandra
Obreja. She is
chair of the DRM Consortium, the international not-for-profit group of
broadcasters,
transmitter/receiver manufacturers and broadcasting unions, who use and promote
the
DRM30 standard for short, medium and longwave and DRM+ for VHF. "In the past 18
months, India and Russia have already adopted it [DRM30] as their digital
solution and have
earmarked serious investment for its implementation."
In July 2010, Indian public-service broadcaster All India Radio issued a tender
for 40 new
medium-wave and five new shortwave transmitters for DRM operation, as well as
the
upgrade of 36 other transmitters to support DRM30.
RELIABLE SYSTEM
DRM30 is meant to replace interference-prone analog AM broadcasting with a
reliable digital
signal that delivers high quality audio plus a host of data features. However,
the system has
been stymied by a limited availability of receivers.
DRM?s progress to date has been "very little in Europe and North America," said
Andy
Sennitt, longtime shortwave radio watcher and editor in charge of the Radio
Netherlands
"Media Network" website. "Most emphasis now seems to be on India, China and
South
America."
However, at the IBC2011 trade show in Amsterdam, the situation showed signs of
changing.
At several events during the exhibition, the DRM Consortium highlighted new
partnerships
with receiver manufacturers that are expected to bring several new models to
market over
the coming year, including new standalone, USB-based, in-car and professional
receivers.
Also, chipmaker Frontier Silicon announced that it was adding implementations
of DRM30
and DRM+ to its Kino 3 radio processor, one of the most widely used digital
radio IC chips on
the market.
However, these positive signs have been a long time in coming.
Gerhard J. Straub, director of the Broadcast Technologies Division at the U.S.
International
Broadcasting Bureau (IBB); the agency that runs the Voice of America and Radio
Marti', says
the slow uptake of DRM30 are shared by all digital radio systems, which have
not benefited
from governmental mandates the way digital television has.
"I think the consumer is overwhelmed with media choices today and unless there
is
compelling content available on a specific platform, what incentive is there to
migrate to a
specific technology over another one?" he said.
Then there?s the issue of supply and demand: Broadcasters don?t want to switch
to DRM30
unless there are enough receivers in use worldwide. Meanwhile, receiver
manufacturers
have been reluctant to commit to DRM, due to a lack of programming.
"DRM is not seen as a profitable line for the major manufacturers," said
Sennitt. "A few
smaller manufacturers have produced DRM receivers, but the unit cost is still
too high, and
there simply aren?t enough DRM transmissions audible at any one location to
stimulate
consumer demand. It?s a classic chicken and egg situation - which comes first,
the
transmissions or the receivers? The broadcasters and the receiver manufacturers
are each
waiting for the other to move first."
ADDITIONAL RECEIVERS
The decisions by Russia and India to adopt DRM30 for domestic broadcasting may
be
changing that equation.
"Our experience over the past year has been that chipset and receiver
manufacturers are
increasingly interested in creating DRM platforms or very often multi-standard
platforms that
accommodate several digital audio solutions including DRM," said DRM Consortium
Chair
Ruxandra Obreja.
In fact, Obreja said. "Our membership has increased in the last 12 months and
it is no
wonder that the companies which have joined us are the top manufacturers of
radio chipsets
in the analog and digital world."
Receiver partners MSway, Frontier Silicon, Chengdu NewStar Electronics and
Himalaya all
highlighted their DRM30/DRM+ receiver solutions during IBC2011.
With the potential DRM30 audience in India and Russia, use of the system in
medium wave
may prove feasible, but for shortwave it may be too late.
While DRM30 theoretically has what it takes to resurrect shortwave into a
digital radio band,
the real culprit behind shortwave?s decline is the Internet: After the Web
arrived, many
shortwave listeners had a better, far more reliable way to get the content they
wanted. In the
developed world, this killed much of the demand for shortwave broadcasts from
international
broadcasters.
In the developing world, however, the need for shortwave radio remains, but
listeners do not
have the money to buy expensive DRM receivers.
"Unless a company comes along with a DRM receiver that can cost less than $40
for
countries in the developing world, it won?t happen," said Keith Perron, founder
of shortwave
program producer PCJ Media.
In the context of a Web-dominated world, can DRM30 save shortwave radio?
"Definitely not,"
said Andy Sennitt. "There are too many other factors that have sealed the fate
of shortwave."
OTHER USES
Glenn Hauser, host of "World of Radio," does hold out some hope for DRM30 on
shortwave,
seeing it being useful for "single-hop coverage at limited distances, as feeder
to relay stations
as with Radio New Zealand International to the Pacific."
In fact, Thomson Broadcast demonstrated a DRM30-based rebroadcasting system at
IBC2011 which would facilitate delivery to local FM stations programming via
shortwave.
"Maybe we should ask that question from another angle," says IBB?s Gerhard
Straub. "If
traditional shortwave broadcasting fades away, someone is going to use that
spectrum for
something, and we can be almost certain it is going to be used with a digital
system. I think
the DRM system has the ability to revitalize the HF spectrum, but I think it is
up to the
broadcasters to find a way to utilize the technology to give the audience
something that they
cannot get somewhere else."
In response to these doubts, the DRM Consortium?s Ruxandra Obreja poses a
question of
her own: "Is there a demand for digital radio or will analog do? The obvious
answer is that in
a digital world, with very congested and limited spectrum resourStandard rig :

** CANADA. 750, Oct 17 at 1202 UT, amid QRM, Canadian news in English about HIV

** CHINA. Firedrake, Oct 17, before 1200:
12230, very poor at 1142; no others found 7-17 MHz by 1151. Higher bands still
mostly dead before sunrise
Before 1300:
7970 and 10300: nothing at 1250
12230, very good at 1256
13970, very good at 1257
16100, very good at 1258
18200, good at 1259-1300*. Yes, 18200, not 18180; none on other bands
Before 1400:
16700, very good at 1348; yes, not 16900
16100, very good at 1348; none in the 15s, 17s, 18s
14700, very good at 1351
13970, very good at 1354
13920, very good at 1354
12230, very poor at 1354; none in the 11s, 10s, 9s, 8s, 7s
(Glenn Hauser, OK, DX LISTENING DIGEST)
** COSTA RICA [and non]. 5954+, Oct 17 at 0347, I can detect a carrier here
under heavy jamming (not 5955), presumably still R. Rep?blica via ELCOR. I hear
that their schedule has been reduced to roughly 0200-0400, and no longer on
daytime 9965, which also continues to be fiercely jammed (Glenn Hauser, OK, DX
LISTENING DIGEST)
** CUBA [and non]. 6150, Oct 17 at 0523, RHC`s crummy squealing and
undermodulated transmitter is gone! But probably not for good. English remained
on redundant 6010, 6050 and 6060. This allowed AUSTRIA to be unimpeded in
German on 6155.
13880, Oct 17 at 1353 I am not hearing RHC`s leapfrog mixing product altho
fundamentals 13680 and 13780 are strong enough, S9+22. Can RHC have suppressed
it? Or made some change in transmitters and/or antennas which are less subject
to intermodulation (Glenn Hauser, OK, DX LISTENING DIGEST)
** CYPRUS. 25985-26010, Oct 17 at 1411, OTH radar pulses presumed from here; no
others at the moment from 22 to 27 MHz (Glenn Hauser, OK, DX LISTENING DIGEST)
** IRAN [and non]. So much for personal diplomacy. Despite my explaining the
collision on 11920 both to delegates from RRI and from VIRI at Dallas HFCC a
month ago, they are still both on the frequency. Oct 17 at 0348, ``Voice of
Justice`` in English is good and clear on 11920, stronger than // 9605, but at
0358 recheck, as usual RRI is on early with domestic service relay in Romanian,
music and announcements before 0400, and is stronger than Iran, a bad mixture.
Who cares about the listeners? It`s so much easier not to do anything, and just
wait for the next seasonal change to take care of it. For B-11, neither will be
on 11920. VIRI plans to move English back to 0130-0230 on 7220 Kamalabad, 333
degrees, and 7230, Sirjan 313 degrees, both for N America, and the latter also
for Europe; While RRI plans to have an English broadcast at 0400-0500, on 6130
and 7305 to NAm, 11895 and 15220 to Asia (Glenn Hauser, OK, DX LISTENING DIGEST)
** MEXICO. Pre-sunrise MW DX Oct 17, UT, with Cant? then IRCA lookups:
670, Oct 17 at 1206 UT, TC as 7:06, ``la voz del pueblo`` slogan again twice,
maybe a program title which seemed to be ending, full ID as Radio Ranchito, mil
watts, including street address in Colonia Ampliaci?n Los ?ngeles, Torre?n,
Grupo Radio M?xico. Then to live DJ mentioning date 17 de octubre
670 XETOR Radio Ranchito Torre?n, Coah. 1,000 250
670 XETOR Coah Torre?n 5000 250 Radio Ranchito, X-E-Tor 1200-0600 NOR/RAN OIR
So they claim only 1000 watts, not 5000, and it sounds like the lower
680, Oct 17 at 1210 UT, greeting listeners who are pescadores, or in Municipio
de Angostura; 1212 mentions ``el sur de Sonora, y Chihuahua``; loops E/W or so.
Greeting fishermen implies it`s near the coast. Altho there are surely several
Angosturas, there is one SE of Guasave near Guamuchil, so these clews lead once
again to:
680 XEORO La Mera Jefa + FM 93.7 Guasave, Sin. 1,000 500
680 XEORO Sin Guasave 1000 500 La Mera Jefa, X-E-oro 1200-0600 RAN RDIO
680, Oct 17 at 1228 UT with KNBR nulled, TC for 6:29, ``noticias en punto``,
news of an event Thu-Sun, norte de M?xico, mentions people coming from diverse
states including BCS, Hidalgo, Durango. CCI from another Mexican with music.
XEORO is also UT -6 but now it`s likely the more northerly one:
680 XEFO ?xtasis Digital Chihuahua, Chih. 5,000 250
680 XEFO Chih Chihuahua 1000 250 W Radio, ?xtasis Digital 1200-0100 JUV CIMA
(Glenn Hauser, Enid OK, DX LISTENING DIGEST)
** NIGERIA. 15120, Oct 17 at 0535, VON is the SSOB at S9+8, report in English
on banking, with background noise, distortion, awful hum. Became slightly
better when returned to the studio (Glenn Hauser, OK, DX LISTENING DIGEST)
** NIGERIA [non]. 9610, Oct 17 at 0530, fair signal and good modulation with
Hamada Radio International ID immediately in Hausa, the clandestine, oops
target broadcast via RMI via M&B due south from Wertachtal, GERMANY, M-F
0530-0600 (Glenn Hauser, OK, DX LISTENING DIGEST)
** OKLAHOMA. 32, since first noticed last week, KXOK-LD, Enid has continued to
broadcast RTV in DTV both on RF channel 31 as listed, and on weaker RF 32, such
as Oct 17 at 1445-1700+ UT. I dropped by the TV-OK office in the Broadway Tower
Friday afternoon, but it was dark. Now I phone them and the person who answers
is unaware of this, but the CE Shawn (Sean?) is supposed to call me back.
I asked Doug Smith of WSMV and W9WI.com and he cannot imagine how there could
be a DTV image or spur on an adjacent channel to the real one. 32 was their
original analog channel. Perhaps the old 40-watt transitional DTV transmitter
on 31 has been moved to 32 as a standby/backup? But it still ought to be on 31
as authorized, not 32.
FCC TV Query has KXOK only on 31; on 32 in OK there are 5 LP CPs, none near
here, and one LP DTV licensed in Altus, certainly not what I am getting (Glenn
Hauser, Enid, DX LISTENING DIGEST)
** ROMANIA [and non]. See IRAN [and non] re 11920 collision all A-11
** RUSSIA. 28555-USB, Oct 17 at 1407, RN3AC, George in Moscow, making hasty
contacts, `beaming stateside` but interrupted for a quickie in Italian, then
English with KA1SJD, Jim in Massachusetts. QRZ.com:
RN3AC
George B. Melnikov
Rossoshansky pr. 2-2-153
117535, Moscow
Russia
Lots more signals on 10m up to 28600 (Glenn Hauser, OK, DX LISTENING DIGEST)
** THAILAND. 9575, Oct 17 at 1358, gong IS and English ID as ``HSK9, Radio
Thailand`s World Service, broadcasting from the Public Relations Department in
Bangkok``, repeat IS and ID. Good and clear signal right after Australia closed
9580. However, off at 1359* and back on weaker at *1400 just in time for pips,
ID as ``Radio Thailand, AM 9-18, time for the 8 pm news magazine``. Must be
delayed an hour since local time is now 9 pm (UT +7). And Udorn must have been
late, making the beam switch from 54 degrees for the 1330-1400 Thai broadcast
to 132 degrees for the 1400-1430 English. Should have done so before the IS/ID
break (Glenn Hauser, OK, DX LISTENING DIGEST)
** TURKEY. 9540, Oct 17 at 1357, VOT IS, Arabic ID, fair. Could be long-path;
is 250 kW, 150 degrees from Emirler at 14-15 (Glenn Hauser, OK, DX LISTENING
DIGEST)
** U S A [non]. 17530, Oct 17 at 1315-1320, R. Sawa interrupts pop music for
fast-paced newscast including axualities, one of them Sarkozy starting to speak
French. Previously heard the other hourly newscast lasting only one minute at
:45. 17530 is 13-15, 250 kW, 285 degrees from Kuwait, and well heard even here
(Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. TP MW DX 9-kHz-step scan on DX-398 with internal antenna only in
offset USB mode, Oct 17 at 1225-1228 UT: very weak carriers on 1044, 828, 774,
747, 738 (Glenn Hauser, Enid OK, DX LISTENING DIGEST)
UNIDENTIFIED. 17535, Oct 17 at 1304-1305* and right back on *1305-1306*, strong
and steady open carrier, just like Greenville used to do a few minutes later on
17820 preparing for the 1700 VOA Portuguese service. Then I check 17820 for a
few minutes past 1315, but DW Hausa is not impeded by an OC, so maybe GB got my
message and decided to find a clear frequency for warmup? Still on 17820 at
1725 check. HFCC A-11 has Riyadh registered on 17535 at 12-14, but I`ve never
heard it there, so presumably wooden (Glenn Hauser, OK, DX LISTENING DIGEST)

70th Anniversary 1941-2011
Six New Features Released
India-Burma WWII
_________________________
The Radio Heritage Foundation releases six new features celebrating
AFRS radio stations in India and Burma during the 1940's at its
global website www.radioheritage.com.
2011 is the 70th anniversary of American Armed Forces Radio
broadcasts, and the six new features look at AFRS radio in a part of
the world that few people today know once had these temporary radio
stations.
AFRS India-Burma looks at the network of 16 stations set up in what
are now India, Pakistan, Burma and Sri Lanka to entertain and inform
US forces during WWII and the campaigns to both protect India and
help the Chinese war effort.
AFRS The Ledo Road visits the network of AFRS stations along the
famous Ledo Road built to bring supplies by road from Northern India
to China via Burma. This feature was written as the stations were
closing down.
AFRS WOTO Bhamo is a contemporary look at the 'Wings Over The Orient'
radio station in northern Burma, one of the stations along The Ledo
Road. This is a fascinating visit inside the operations of one of the
most isolated AFRS stations in the region.
AFRS VU2ZP Bangalore introduces the personnel and programs that made
this local AFRS station one of the most popular in India during its
short time on the air. Rare photos from the private collection of one
of the original VU2ZP broadcasters bring extra meaning to the written
words.
AFRS VU2ZP Signs-Off is a retrospective of the Bangalore station,
including its sleepless monitoring that helped it be the first
station in India to report the end of the war in Europe. Again, rare
photos of staff and VU2ZP studios make this a special feature.
AFRS VU2ZS Misamari is another contemporary indepth look at the
people and programs of the small AFRS station at Misamari.
These six new items are in addition to the introductory feature AFRS
China-Burma-India already at www.radioheritage.com. This also covers
stations in China and remains the only comprehensive listing of the
stations involved.
The features have been made possible by CBI veterans and their
families preserving a variety of original resources such as magazines
and photos and we encourage support for their projects. We're pleased
to help bring them to a broader audience.
Many other AFRS radio features at www.radioheritage.com include rare
photos and personal memories and stories from the past 70 years of
AFRS operations.
The Radio Heritage Foundation is a registered non-profit organization
connecting popular culture, nostalgia and radio heritage at its
global website www.radioheritage.com.
Sponsors now get a free World Radio TV Handbook 2012 shipped
worldwide for their support of this international project. You can
also choose your personal favorite feature to sponsor - included in
your sponsorship - for even greater public acknowledgement. Full
details are at www.radioheritage.com.
