Subject: RE: FM transmitters - any suggestions ?
From: Simon, Wesley (wsimon_at_lsil.com)
Date: 2003-01-08


I'm curious about all these FM transmitters that are being talked about.
Has anyone taken into consideration the bandwidth these things are capable
of transmitting? I was under the impression that you could only pack about
the equivalent of an 56Kbps mp3 sample rate into the bandwidth of an FM
radio station. So, one must wonder if frequencies are being dropped by the
transmitter or if it's sampling at a low rate.

I'm looking at buying a new head unit for my truck and have decided that an
input jack on the face is mandatory. To me, it doesn't make sense to spend
$200 - $300 on a player, ~$1000 on a stereo system, then limit the quality
by buying an FM transmitter that will degrade the quality to that of an mp3
file that I (or most people) wouldn't even download given the opportunity.

I'm not really being picky here, but I would offer these thoughts for
everyone to consider before purchasing the FM transmitter.

I get acceptable results (not trouble-free, but good enough that I do
listen) using the C.Crane

in Chicago and suburbs. Usually I can find a free channel, but college
stations come and go, so sometimes I have to change frequencies while
driving.

I have to admit, a modulator-only unit, such as the "Microboss" modulator
which Thierry mentioned
http://www.microboss.de/mp3/mp3_english/mp3carrock.htm
sounds like a better idea for the car, and cheaper.

The only advantage to the transmitter is sometimes it is handy to be able to
bring it into friends' houses and play through their radios without need of
cables.
