Hi,

I just want to know is Kiwa filter an absolute requirement for 2010?
What would be shortcomings of 2010 without it. Does Kiwa filter make
major/substantial perfomance impact?

The Sony 2010 comes with two filers: The wide is approximate 9.4kHz
with a shape factor of 1:19, meaning signal is down 60dB at 17.9dB.
That's what I would expect in a $25 portable radio. The narrow is
appoximately 4.3 with a shape factor of 1:2.4, meaning signal is down
60dB at 10.3.

Compare those figures with a Grundig Satellit 500: Wide is 6.6/13.2,
and narrow is 4.2/8.0.

SONY got by using a CHEAP wide filter because of the sync detector.
The narrow filter produces too much distortion for me, and wide filter
is so wide I sold my 2010. The Satellit 500 has EXCELLENT wide AND
narrow filters and does an excellent job of rejecting adjacent
signals. Also, the narrow filter on the Grundig doesn't produce so
much distortion, yet it is narrower than the Sony. Sony is a loser in
my book. I got rid of mine because of the cheap filters and replaced
it with a superior Grundig.
