Re tests on amateur radio band frequency 7105 kHz of these Made in China
BBEF transmitter from Radio Bangladesh Betar Khabipur site on August 14th.
This is causing very harmful interference to the Amateur Radio Service
world wide. The Amateur Radio Service has an exclusive allocation in this
range.
As the range 7000 - 7200 kHz is allocated world wide to the Amateur Radio
Service, these transmissions are causing very harmful interference to the
Radio Amateurs world wide.
See United Nations ITU Radio Regulations of ITU 4.5
and Circular Letter of ITU Switzerland CR/282 3.2!
The Radio Amateurs of the world have the right to use their exclusive
Amateur Radio frequencies without the very harmful interference of
"Bangladesh Betar".
Dear radio amateurs, thank you very much for taking action on this matter!

Now at 1940 UT another bcast of S=9+25dB noted on 7105 kHz.
This segment of ITU plan belongs to Amateur Radio worldwide from 7000 to
7200 kHz.
The first broadcast channel is 7205 kHz and upwards.
I'll inform the IARU and ITU bandwatch organizations immediately, to stop
these unlawful behaviour of - most probably - Bangladesh Betar Radio
broadcaster.

Nice clear S9+40dB signal here at 1820, very little interference or
fading, music and English commentary. Audio still seems indistinct in
AM mode, much better clarity in USB mode
