The sound signal is input by microphone, amplified by Q1, Q2 transistor, then through R7, C3, D1 attenuator, at last the loud voice is filtrated by C5, C6, thus in this way to avoid the bandwidth exceeded 200KHz. The sound signal is transmitted by Q3 transistor to reach frequency modulation. (Please refer to the diagram). 2. The transistor oscillator circuit is composed of Q3, R11, C7, C8, L2, C11, and C13. FM signal is combined by C10, after resonated by L1, C12, C15, then through L3 and antenna to be launched outside. (see the diagram) Chinese version: 1. 声音信號經過咪頭輸入後, 經過Q1, Q2三極管放大, 再經R7,C3,D1衰減音頻信號後再經C5, C6 過濾 “高音”, 以防調幅超過200KHZ。 声音信號通過晶體管Q3, 逹到調頻(見圖). 2. Q3, R11, C7, C8,L2,C11,C13構成晶體振動綫路。調頻信號由C10耦合，再經過L1,C12,C15諧振 後經L3, 天綫發射出去。 Thank you for your support. Best Regards, Karen / Fanny, Columbia Telecommunications Ltd.

FCC ID: GAFMIC2 Circuit Description The 98MHz LCR oscillator drives the base of Q3 the final/buffer amplifier. The modulation provided by MIC. The output of Q3 has the matching network consisting of C15 and C12 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
