Just a suggestion, a LSP hard and fast rule is 44100hz, 16pit pcm, and 128 kbs and stereo for your music files or you will eventually have issues. Audacity usually does the fix to set all of these settings.
Good point especially for MP3 files. I use all WAV files for the reasons I stated. Once I figured out my FM Transmitters Audio Response specifications, and then filtered the music WAV files, the sound is unbelievably clear and crisp coming from my EDM FM transmitter. If you tune to my station, you can't tell I'm an armature, Low Power, Non-License station out in front of my house. I am so glad I got that unit.
Hi CJ, where did you buy your EDM Transmitter? Sounds like I might have to upgrade.
I am extremely impressed with this Transmitter. I bought EDM-LCD-CS-EP, 100mW PCB, Parts, Antenna, Regulated 12V PSU, Includes metal enclosure, Adjustable RF output, 1-10mW and 2-100mW.
It's important that you have a metal case, so do not operate an FM Transmitter without a metal case, you will be disappointed in performance.
It cost me $159.00 and I bought it directly from EDM's web site at You are not allowed to view links.

Mine already had the PIC chip installed, so all I had to do was solder in the Power Cord adapter and go to Radio Shack and get some adapters to connect my CB Coax from the PL259 to an RCA jack. It was easy and EDM answers your email spot on. There is nothing bad I have to say about this unit. For the money, it's outstanding. I build my own 1/4 ground plane antenna, see the WiKi on FM Transmitters and I turned down the RF output to 1mW and get exceptionally good performance. You won't be disappointed.
