Circuit Description The 88.1, 88.3, 88.5, 88.7, 88.9, 106.7, 106.9, 107.1, 107.3, 107.5, 107.7 and 107.9MHz IC oscillator drives the base of IC2 the final/buffer amplifier. The modulation provided by Audio Input. The output of IC2 has the matching network consisting of L5 and C23 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source There is no external antenna. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3 Volt ("AAA"size battery x 2) primary battery
