Here is a great entry-level kit that will teach the basics of FM Broadcast Transmission while finding many uses around the home or dorm room. The FM10C has plenty of power to cover your home, back yard, or city block. Our manual goes into great detail outlining all the aspects of antennas, transmitting range and the FCC rules and regulations. You'll be amazed at the exceptional audio quality of the FM10C. Tunes through the entire 88-108MHz band in three separate ranges with a tuned LC circuit. Re-broadcast your favorite music commercial free and with the dynamic range the musician intended, without all that nasty compression the big boys use to make their station sound louder than the competition. Compression produces a noticeably muddier and less dynamic sound. The unit runs on internal 9V battery, external power from 5 to 15 VDC, or an optional 120 VAC adapter is also available. Includes the matching case & knob set for a professional finished look. Case size 5"W x 1.5"H x 5.25"D Note: The FM10C is a do-it-yourself learning kit that you assemble. The end user is responsible for complying with all FCC rules & regulations within the US, or any regulations of their respective governing body.
