FCC ID: H8A1210 Circuit Description The 370MHz IC oscillator drives the base of Q1 the final/buffer amplifier. The modulation provided by Mic., U1 and U2. The output of the matching network consisting of L1 and C1 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 6Volt (“AA” x 4) primary storage cell.
