I am looking for investigating if it is possible to buy a multi
frequency FM transmitter. I want to broadcast a FM signal out on the
whole range of 87.5-108 MHz. i want the output to be limited to about
a couple of hundred meters of diameter, does anyone have a clue if

I have a few various car chargers that accept USB cables, attaching to
various devices with a mini-USB connector.  Each has its own output,
from 500 mA to 1000 mAmps.  I just purchased a new device (Callaway uPro
GPS).  Its car charger has an output of 500 mA.
