Direct Input

It looks like I am going to have to go with a FM Modulator. Is there a web site that rates these devices. At this time, I'm using a cassett interface to connect to my MP3 player. Im interested in the frequency response thats reproduced and will it sound as good as an FM broadcast.

I really don't know that they are even worth rating, the sound quality will be fairly poor with pretty much any of them. To answer to your question, I know of no such site.

Ok, well thats what I need to hear. I have a sirius sat radio that has a fm trans and that sounds the same way. Like an AM radio. Well it looks like I'm going to just persue making a direct input to the circuitry. Thanks for the feedback ............... Rick
