Antenna:The antenna should be a half or quarter wavelength long(for 100 MHz, this is 150 cm or 75 cm). I suggest you use a 75cm piece of wire or an old extendable <strong>FM</strong> radio antenna(like the one shown here).Battery:I suggest you run this circuit from a 2x1.5 V battery set. I donot recommend using a common 3V DC supply since thoseare not well regulated, and the variations in their voltage might affect your circuit. If youdecide to use a DC power supply, however, I suggest you use a heavily-regulated DCsupply (or add a regulator yourself) to get the best results.Use a CD or mp3 player as the input to your circuit, then use an <strong>FM</strong> radio to listen to yourtransmission. Be prepared to present your work and answer any questions I ask about yourcircuit.Page 2 of 2
