| Development
of the Tecsun BCL-2000, from idea to design to manufacture of
an engineering prototype has taken about a year.
The
BCL-2000's primary strength is in FM DX, with a range of some
200 km (125 miles). The radio has its own antenna and can be
fitted with external ones as well.
BCL-2000
uses 4 integrated circuit (IC) chips, with fast or slow turning
system (speed ratio of 4 to 1). Its standby current is 80 mA,
the display precision is 1 kHz; it has a built-in power transformer;
and employs a 3 unit variable capacitor tuning system.
Frequency
ranges are: FM, 87-108 MHz, MW 520-1610 kHz, SW1 3-8 MHz, SW2
8-17 MHz, SW3 17-28 MHz.
The
radio has no PLL. It's a single conversion design, with no stereo
headphone jack, and no memories.
Dimensions: 272 by 173 by 88 mm. Sensitivitywas tested by a
listener using the the telescopic/internal antenna and claims
it to be equivalent to the Sony ICF-SW7600GR on FM, and better
than the Sony or the Sangean ATS-909 on MW/SW..
Thanks
to Tao Jian and HongKongRadioer for sharing these photos and
a preview of what might be an interesting offering from Tecsun
when it becomes avalable for sale.. This preview would not
have been possible if not for Ali Nikseresht who sent these
photos along and helped to edit Tao Jian's preview. Good job
fellas!
