Subject: Re: FM transmitters - any suggestions ?

RE: FM transmitters - any suggestions ?Actually an MP3 is much higher quality than a FM Stereo broadcast...do a lil'reasearch and youll find that FM cuts out ALOT of frequency. Any how if ya want a decent FM transmitter you need to spend about $100 - 150 http://www.ramseyelectronics.com/ sells a FM25b for $140 and http://www.freeradio.org/ has an exciter for $115 ...both are 1watt kits and legal. I have been operating a FM25a for years I really like it. Both listed here are kits and require asembly (soldering). Takes about an hour or two to do.

  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
  http://www.ccrane.com/fm_transmitter.asp
  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.
