Kalurghat Betar resumes operation
By BSS, Dhaka
Mon, 18 Jun 2007, 12:58:00
The Kalurghat radio station of Bangladesh Betar in Chittagong, which was
affected by excessive rainfall, resumed its operation at 12 noon yesterday
after remaining closed for one week.
Transmission of the 100-kilowatt medium wave transmitter had stopped as
water stood in the station compound after the heavy downpour of June 11,
said a press release of Bangladesh Betar.
However, in the last one week, programmes of the FM band continued to be
aired from Agrabad Bhaban that could be listened to only by the audience in
Chittagong city and adjoining areas.
During the week, Cox's Bazar and Barisal stations of Bangladesh Betar
expanded their sessions from 6am to 10am and 6.50pm to 11.10 pm everyday and
broadcast the Dhaka station's programme for the audiences of greater
Chittagong, especially for those who live at costal region and deep sea
area.
A three-member experts' team of Bangladesh Betar, led by additional chief
engineer of Dhaka station, reached Kalurghat radio station from the capital
soon after the incident on June 11 to assist the concerned engineers in
resuming the operation of the transmitter. The team was able to make the
transmitter fully operational this noon after working round the clock for
the last one week.
The Bangladesh Betar authorities have expressed regret to their audience in
greater Chittagong, particularly those in the coastal areas, for the
inconvenience caused to them during the last seven days, said the press
release.

Dxers Unlimited
Dxers Unlimited's midweek edition for 19-20 June 2007
by Arnie Coro
radio amateur CO2KK
LATE BREAKING PROPAGATION NEWS
Solar flux at very low levels = 67 units
There seems to be an inverse correlation between
very low solar flux and Sporadic E layer events...
Sporadic E openings reported by 6 meters radio amateur operators from
the Caribbean to the Canary Islands and Western Africa
Also many reports of Sporadic E events from North America
to Europe and to Hawaii !!!
Now here is the script of the the mid week edition of the show
Hi amigos radioaficionados around the world and in space... your radio
receiver is tuned to one of Radio Havana Cuba's short wave frequencies,
or maybe you are connected to our Internet streaming audio...that
is available from 05 to07 UTC from our URL at rhc.cu... look for the
loudspeaker icon sign at the top of the home page !!!
Whichever way you are listening is certainly nice to have you here with
me, ready to share about seventeen minutes of all radio hobby related
information. I am Arnie Coro broadcasting from beautiful Havana, where
the weather when I was writing the script of the show around 10. AM
local time , that is 14. UTC, was very enjoyable with a wonderfully blue
sky , a typical summer day here in, but the weather service forecast
says that we may be having afternoon thunderstorms...
And, amigos our T storms are pretty special, with tremendous
lightning strikes that do a lot of damage to radio equipment that is not
properly protected , and talking about T-storms today I am bringing
again at the request of many listeners a special feature from New
Zealand radio amateur ZL3NE, Zulu Lima Three November Echo, in which he
sustains something that I found out and published exactly 41 years ago
in 1966 .
In other words, the New Zealand radio propagation expert is convinced,
as I am too, that T-Storms have are somehow linked to a certain type of
Sporadic E layer propagation openings !!!
More about propagation briefly: solar activity at extremely low
levels... with the 10.7 centimeters microwave radiation from the Sun
around 67 units, a figure considered by scientists to be the baseline
activity of the Sun, and of course, quite normal during the solar
minimum years.
Standby now briefly for a short break and station ID... Dxers
Unlimited's midweek edition will continue in a few seconds.
......
Amigos you are listening to Radio Havana Cuba, the name of the show is
Dxers Unlimited, and here is our special report for today... New Zealand
Propagation expert's information, coming from a link on the DF5AI VHF
propagation research website.
Have paper and a pen ready or your tape recorder at hand, so that you
may be able to copy the URL of DF5AI 's excellent website.
Now here is ZL3NE's report:
He starts his comprehensive analysis by explaining one particular VHF
propagation event that happened
on the 22nd of May of 1999. Looking at the North American weather map
which showed where thunder / lightning storms of high intensity were
located, and above the location of the Millstone Digisonde station there
was a sign of good activity. This looked interesting, so I looked at the
dxworld.com 6 meter page and here we had contacts taking place from
Canada to the United States directly over the Lightning storm as shown
in the map.
Armed with this information he connected to the Millstone web page and
looked up the time list, down loaded their charts and there it was
showing up very nicely. Their chart showed that the E layer had reached
12.5MHz. Taking the usual multiplication factor of 5 we now had
propagation recorded for 6 meters. A confirmed mode of propagation
induced by lightning, (otherwise known as sporadic E), as we had the
weather map showing the lightning storm, the contacts and the ionsonde
charts showing ionization to 12.5 MHz all at the same time.
When the storm died out, the ionsonde data returned to normal and
propagation ceased.
Here is now another very interesting report, that has a tremendous
scientific value, because the phenomenon repeats itself with amazing
identical effects on the Southern Hemisphere, the event happened on
December the 21st 1995 at 6pm. ZL3 NE describes that on that day from
5pm to 6pm he had a poor opening on 6 meters to Sydney. At two minutes
past 6 pm the band suddenly opened with Sydney stations S9+, then I
found I had VK6 stations S7. (Western Australia 5000 km ).
After exchanging reports with these I switched to two meters and yes the
Sydney stations were S9 on two meters. Just before 7pm I listened to the
TV weather for my lightning update, and what did they say? A very
aggressive thunder storm started at two minutes past six, and that it
was located in the center of the path between Auckland and Sydney. That
was exactly the same time as both bands opened here! Local stations
further north or south of Auckland did not get the propagation like we
had, as their path was out of the area ionized by the thunder storm.
The next day the news papers commented that the storm died out around
8pm and that was the time when two meters closed to Sydney. For this
type of information it is a do it yourself job and these are things you
have to organize yourself as they are not available of the shelf.
The New Zealand propagation expert then describes yet another very
interesting VHF propagation event when that he heard VK9NS in Norfolk
Island some 1200 km north of his location calling ZL4BTN.
He had perfect copy of VK9NS by back scatter with a lightning storm
centered between him and the ZL4.He called Vk9NS and exchanged
reports,but at that moment he could not hear him on the direct path.
This is a perfect example of back scatter with signals being reflected
off the ionization brought about by the lightning flashes.
And ZL3NE underscores that we get a lot of propagation like this as cold
fronts sweep up the South Island from the South and these usually have
lightning storms in the leading edge of the cold front. Half way between
Christchurch and Auckland is an area which grow a lot of apples so when
they get hail from thunder storms the media reports as to how many
thousands of cases of apples etc were destroyed, and yes every time he
gets these reports he finds his log full of 6 meter band contacts with
Amateurs in Christchurch, New Zealand, once again, confirming that
lightning generated during the thunderstorm produced the abnormal
Sporadic E skip propagation.
Now, be ready to copy as ZL3NE is producing a daily VHF propagation
forecast for North America on a daily basis, and this is what he
published at his website on Saturday June 24th. 2005..
VHF Propagation Forecast for
North America, based on the Weather conditions prevailing on Saturday
the 24th of June at midday in W0.
Situation. A long warm front extends from W1 to W5. Lightning from T
storms present in the following US call areas 4,5,7 and 9.
Typical paths. W4 to 5. W4, 5 to 7 and 9. W6 and 7 to W890. Prop from
VE567 south .
Again a quiet day for tropo but watch for Es from over the lightning
storms in W4579.as this is the best time of year for this.
Well amigos, I am now sure that many of you will start looking with
great attention to the most comprehensive weather maps available !!!
That's what I have done here since 1963, when I started to notice a very
clear link between the San Jose ionospheric vertical incidence sounder
recordings and amateur radio reports of 6 meters band propagation , and
also of reports sent to several club magazines by TV and FM band Dxers...
.....
Si amigos we do QSL, we continue to QSL now with our beautiful 45th
Anniversary of Radio Havana Cuba QSL card, on Monday I autographed a big
stack of them so that Irma can send them to RHC listeners around the
world that send us signal reports and comments about our programs. Send
your reports via e-mail to
[EMAIL PROTECTED]
again ,[EMAIL PROTECTED], or VIA AIR MAIL, send a postcard that is of course
less expensive, to Arnie Coro, Radio Havana Cuba, Havana, Cuba...
Now here is our next item , our popular technical topics section, that
will feature today information on how to prepare a special extension
cord for your radios that will protect them and also help to reduce the
noise coming from the power line. Here is HOW TO do it..
Obtain a length of around 3 meters but no more than 5 meters of good
quality number 14 three conductors flexible power wire, a 100 by 100
millimeters or 4 by 4 inches plastic junction box and a three prong male
power line plug .
Fit the three wires to the male power plug carefully, watching that you
follow the color code for the ground wire approved by your electricity
board, and proceed then to put on the box two dual power line female
receptacles, that will give you 4 connecting options.
Connect the other end of the power cord to the two dual
female receptacles , and then place in parallel with each of them a
SURGE SUPPRESSOR rated for 130 volts AC.
The SURGE SUPPRESORS are sold under different names.. like TRANSZORB ,
SURGEKILLER etc...and they are rated for specific applications.
That will complete phase one of your equipment surge protected homebrew
extension cord, so now we can proceed to add the four 1 kilo volt .01
micro farads disk ceramic capacitors that are connect from each side of
the power line to ground.
After the ceramic disc low inductance capacitors are added , your
extension cord plus junction box will also help to bypass radio
frequency noise to ground before it reaches your radio's power supply.
You may want to add a toroidal core of large enough diameter and wind
the two live wires trough it for at least 10 turns, but if you can't
find the toroidal core, I have achieved good results using a ferrite rod
and winding ten to fifteen turns of the two plastic insulated wires that
are live.
The other option available, that will cost you practically nothing and
could be a last step in assembling your homebrew extension cord, is to
search for a discarded TV or computer CRT monitor, disassemble the
horizontal output transformer square ferrite core, and use it to wind
about 10 turns of the three wire cable as near as possible to the
junction box.
Of course that you can use a bigger box and instead of 4 female sockets,
you can have 6, 8, 10 or even 12 sockets to connect your equipment .
Tests done at my home QTH and at several more locations show that using
this homebrew extension cord fitted with transient suppressors, and
radio frequency blocking devices helps to reduce the noise picked up by
the typical low or medium prized radio receivers.
As you may had realized , homebrewing this power cord doesn't require
the use of special tools... as a matter of fact a screwdriver set and
diagonal cutting pliers are all the tools needed to assemble this very
useful addition to your listening post of ham shack...
.....
And now amigos, as always at the end of the show, here is Arnie Coro's
Dxers Unlimited's HF propagation update and forecast... Solar activity
is at extremely low levels, sunspot count during the past several days
was ZERO, repeat ZERO, and the equivalent daily solar flux is at rock
bottom levels, not even reaching 70 units and not expected to move up
soon, but because solar scientists are detecting signs of increased
activity at the Sun's limb, an indication of an active sunspot group
about to rotate into view this quiet Sun condition may change later
during the week.....
Don't forget to send your signal reports, radio hobby related questions
and the all important for me comments about this program amigos.
Your comments do help a lot to select the topics
to be dealt with here, and also which radio hobby questions are most
important for the audience of Dxers Unlimited...send mail to
[EMAIL PROTECTED] or VIA AIR MAIL to Arnie Coro, Radio Havana Cuba, Havana,
Cuba. See you all at the weekend edition of the show, on the air
Saturdays and Sundays UTC...
