FCC ID:KT6B-7007 Circuit Description The 89.125MHz oscillator drives the base of Q2 the final/buffer amplifier. The modulation provided by Mic. The output of Q2 has the matching network consisting of L3 and C3 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source The antenna consists of a 19cm long metal wire. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3 Volt (“AA” size battery x 2) primary battery The transmitter (EUT) is a 3 button transmitter. The EUT continuous to transmit while the button switch to “TX” position. EUT is voice transmissions, so modulation provided by mic. user FM radio turning the same frequency to EUT, then it will received sound from EUT. Modulation type - Frequency modulation Signal type - Narrowband signal Information being sent - voice transmissions Pulse repetition rate - 3 msec

TEST REFERENCE: FCC Rules Part 15 section 15.239(88.00-108.00 MHz) TEST CONDITION: Normal TEST DATE : 2000-12-02 RESULTS AND NOTES The bandwidth of the emission shall be no wider than 200kHz of the center frequency for devices operating within 88.00MHz to 108.00MHz. The bandwidth is determind at the points 26dB down from the modulated carrier.
