Hi All,
I just got a FM transmiter module from supplier, after my test, its
every channel occupy almost 0.5MHz of range.
For example, when I tune to 100MHz, I can hear it from 99.7MHz~100.2MHz
and only 99.7MHz didn't show "Stereo" tag on screen, others (
99.8~100.2MHz ) all show "Stereo" tag.
How is this quality ? I test general FM radio music, the range is not
so big. ( about 0.2MHz~0.3MHz.) and only 0.2MHz range with "Stereo"
The FM module occupy 0.5MHz range, is that too big for worldwide use?
btw, I can feel the quality is not as good as FM music radio, does that
mean the FM module chip's audio quality is not good enough ? it seems
that I didn't see the quality spec ( SNR ...etc ) on FM module
specification.
