Operational Description

APPLICANT: CACHE SALES FCC ID: ZEZ3107T27 Circuit Description Q2 the 27.145 MHz crystal oscillator drives the base of Q2 the main transmitter oscillator. Summed into the same base (Q1) is the modulation provided by U1. The output of Q1 has the matching network consisting of L3, T1, C1, and C2 that limit the trapezoidal filter content and effect the proper coupling of the antenna to the output stage. Antenna, Ground, and Power Source The antenna consists of a 60cm long telescoping chrome over brass tubing. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 9 Volt primary storage cell.

The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100 kHz and the video bandwidth was always greater than the RBW. Occupied Bandwidth: A small sample of the transmitter output was fed into the spectrum analyzer and the following plot was generated. The vertical scale is set to 10 dB per division. Formula…
