re: MLI - CHN relay site contract.That means due of limited local main power circuit, the origin
BBEF 150 kW type manufacture called TBH 522 of 2005 year,
were in use as limited down to 100 kW only. Despite the MLI - CHN diplomatic contract mentioned of 150 kW units
to be used at the African CRI relay site ?
RTM 4783 and 4835v were only by 50 kW of power.
MALI Checked yesterday Monday March 11:
7295even MLI CRI Bamako in Mandarin at 23.10 UT in BEL/GER only tiny S=4 or -98dBm, l o w modulated signal,
S=8 in Doha Qatar SDR unit,
S=9+5dB -68dBm in Massachusetts US state,
in New Jersey and
S=9+10dB or -63dBm in Cape Canaveral Florida too. 11975even MLI CRI Bamako in Mandarin at 23.14 UT 11975 was tiny weak in MA at S=4-5,
S=7 or -86dBm in New Jersey,
S=8 -80dBm in Cape Canaveral FL at 23.17 UT,
S=7 or -86dBm in Doha Qatar ME. MALI 5995.000 even plus a half Hertz ...
RTM Radio Mali Bamako, the 50 kW unit heard l o w modulated
in French annmt and long lasting guitar mx program 22.56 to 23.02.30 UT
then French talk followed, S=7-8 or -83dBm noted here
in west European SDRs.
Much QRM by adjacent RHC Quivican TITAN San Felipe outlet
across the Atlantic on even 6000 kHz. Compared IBB BBG VoA Botswana relay transmissions at same time / meterbands
were always a S-step stronger than Bamako Mali transmissions. 73 wolfie df5sx ----- Original Message -----

re:
the contract between our station and Mali had expired, (...)
The new Bamako site was erected in new China antenna design in
2003-late2004/spring 2005 year,
til came into service in July 2005 and was reported in DXpress then.
I've some CRI Bamako entries in my archive then.
And also visible first in G.E. images of this 2004/2005 year.
So seemingly there was a 15 years contract,
came into effect between August 2003 and last til 2018,
when CRI forced to stopp their Africa/NE broadcast service there,
... and DXers told that the world last year.
cloned SW and MW units worldwide (...),
At this era 2003 - 2005 the Beijing transmitter firm
Beijing BBEF Science & Technology Co., Ltd
erected a lot of 50 kW units,
the website also presents the 50 kW variant TBH 422, 100 kW (in Albania renamed to 'SW100F'), 150 kW type manufacture called TBH 522
(in Albania renamed to 'SW100A'), cloned SW and MW units worldwide. by Beijing BBEF Electronics Group Co. Ltd.,
like totally new Bauta-CUB site refurbished by 6 x 100 kW
and erected a total new antenna field there, Cerrik-Albania refurbished in TX and antennas,
have got 6 x 150 kW, and an antenna combined switch net
to put 2 TXs together at 300kW of power.

"Seemingly" of course means that this is a description of presumed
arrangements. I have never seen any details about the Chinese engagement
in
Mali. The question about the site is in fact a very interesting one. First there
is the shortwave-only station at Kati: https://binged.it/2u2i3v5
Then there is the MW/FM/TV station between Bamako and Kati which has also
shortwave antennas, essentially the same set of bearings than at Kati:
https://binged.it/2u23rLW
These antennas are of a design that appears to be connected with a use of
US-made transmitters. And now take a look at this:
https://www.swcountry.be/mli.html Anything else remains plain speculation (including the question whether
the
alleged three transmitters from 1996 have now been refurbished or perhaps
completely replaced; all the previous equipment appears to have been
decommissioned already years ago, leaving only 2 x CRI plus 9635/5995
ORTM),
but at least it is obvious that the history of the Bamako shortwave
operations is a bit more complicated and interesting. By the way, any memories how the Radio Beijing relays sounded when they
begun in 1987? Was it the same 200...3400 Hz crap with lots of nonlinear
distortion as still heard via Switzerland, Russia and France during the
nineties? Kai --------
Here's an old (2009) news item about 3 SW transmitters installed by China.
Header says 150 kW but text says 2x100 kW for CRI and 1x50 kW for Radio
Mali. But who knows. I get an impression these are near Bamako (some 10
km)
on the Kati Road. Nearby there is also radio center called Point G - I
guess
for TV etc. operation. The text says the two shortwave transmitters are
leased to China for 10 years (2007-2017).
