总的来说:老外认为价钱便宜,虽然无SSB和同步检波,但具有极好的性价比.
Pros: Incredibly sensitive, Great sound, Low price
Cons: Mediocre construction, no SSB/Sync, Tuning challenges
I picked up the Tecsun BCL 2000 from an Ebay auction, having been
drawn to the black color scheme. Once it arrived from Hong Kong, I
excitedly opened the box, and, in an attempt to avoid the scrutiny of
my ever-watchful wife (what, ANOTHER radio?), I set it up on my
garage workbench. Seeing that the supplied manual was written
entirely in Chinese, I was left to my own devices to get the radio
operational; This proved to be only a minor challenge. The control
layout made perfect sense, and within 30 seconds, it was up and
running.
Being about 0200 UTC, I tuned to 31 meters. With only the whip
antenna, I was expecting to faintly hear some major broadcasters, but
I was totally stunned: This little radio was pulling in signals, big
and small, with booming audio clarity!
Is it the ultimate receiver? For $100, of course not. It held it"s
own with my SW77 and Grundig 800 on the lower frequencies in
sensitivity, with a sound fidelity better than the Sony, and equal to
the (much, much larger) Grundig Satellite 800 on most stations. For
weak stations under tough conditions, I"d take the Sony or the
Grundig...at four or five times the price. That being said, the
narrow filter position did a nice job of filtering interference
without overly muffling the audio.
It did a respectable job on medium wave. It"s hard to tell with all
the local light dimmers that I have to put up with. The nod for
fidelity goes to the CC Radio, but not by much.
The down side? The external cabinet seems about average, although the
knobs are downright delicate. I"m worried that with one good twist,
they"ll come right off. The antenna is solid, the battery life is
great. Tuning is an experience. It requires a delicate touch, and is
apt to drift. Hey, it"s a $100 analog set for goodness sake!
Sure, no Sync or SSB, but for doing what it was designed to do,
namely, listening to Shortwave Broadcasts, it is an awesome box.
One final story. My technologically-jaded 15-year-old started playing
with the tuning knob, and after a short while, was hooked. Having
lived his entire life in a push-button-direct-entry world, he had
made an analog "connection" with this little radio, and couldn"t take
his hands off it.
Like son, like father.
