From: Herbert Graf Subject: [EE]: FM transmitter problems >I built an MP3 player out of a Pentium PC and installed it in the car. Oh my, anyways try piping signals from two different sources into your FM stereo transmitter L & R channels, and see if it creates the same .5Hz fading. Perhaps there is some kind of wierd correlation between how L-R signal is encoded on the CD, and encoded in FM stereo. Try switching L & R channels too. hit from yahoo search of "stereo FM transmitter subcarrier L-R" http://members.tripod.com/~transmitters/stereo.htm Scott -- http://www.piclist.com#nomail Going offline?
