EXPOSITORY STATEMENT/DESCRIPTION The AEK992249R "The Beetle" is a superheterodyne receiver. The RF input signal enters the LSI (Large Scale Integration) via a permanently attached wire antenna. The antenna length is approximately 15". The superheterodyne receiver operates with an IF frequency of 1 MHz, 49.86 MHz carrier minus 48.86 MHz LO. The LO oscillator frequency is generated by the following external circuit components: - X1 Xtal - 48.86 MHz - X2 - 2.2 uH Coil - X5 - 56k resistor - X3 - 0.68 uH Coil - X4 - 100 pF Capacitor The LSI IC then extracts, internally, the digital modulation control codes from the signal and supplies these control signals to the receivers motor drives for forward/reverse and left/right vehicle functions. The digital control codes are then delivered to the motor controls via the two digital comparitors, IC2 and IC3. These comparitors then control the two electric motors, M1 and M2, to allow the vehicle (toy car receiver) to advance forward (left/right) and reverse (left/right). The receiver system operates on 9 VDC, supplied via one 9 VDC battery. No external ground system is needed or used with this device.

EXPOSITORY STATEMENT/DESCRIPTION FCC ID:AEK992249R The BEETLE The relaxation oscillator receives the RF signal from the transmitter then amplifies and detects the control signals and subsequently supplies the digital control signals to the comparitors and motor drive circuits for controlling the movements of the receiver. The superregenerative receiver is comprised of the superregenerator relaxation oscillator circuit, which consists Q1, and its associated passive components, and the detection circuitry located within IC1. The digital control signals are then supplied to the comparitor circuit and motor drive circuits, via IC1's control signal output ports labeled FWD (forward), BACK, RIGHT, and LEFT. The receiver is powered by a 6 VDC battery pack. No external grounding is used or required. The only tuning required is to tune the relaxation oscillator, L2, to receive the RF from its associated transmitter, and is performed at the manufacturing facility by qualified technicians.

GENERAL TEST CONDITIONS AND PROCEDURES Measurement procedures were used as outlined in MP-1, as specified in Part 15.31, except as noted herein. The open field tests were performed on a three-meter range maintained by Carl T. Jones Corporation at the Springfield facility. Complete description and measurement data for the site have been placed on file with the Commission. Carl T. Jones Corporation is listed by the FCC as a facility available to do measurement work for others on a contract basis. Prior to open-field testing, the equipment was placed in a shielded enclosure and scanned at a distance of 1 meter to determine its emission characteristics. IV. RADIATED EMISSION MEASUREMENTS The receiver was assembled on a rotatable wooden test stand approximately one meter in height. The receiver's antenna was fully extended. Because of the superregenerative nature of the receiver, an FCC ID:AEK992249R 3 unmodulated RF signal was transmitted to it during testing in order to insure proper functionality. The emission spectrum was examined from 30 MHz to 1000 MHz using a Hewlett-Packard 8568B spectrum analyzer and Compliance Design "Roberts" tuned dipole antennas. At each emission frequency, the EUT was rotated 360 degrees, and the antenna was raised and lowered from one to four meters to determine the maximum emission levels. Measurements were taken using both horizontal and vertical antenna polarizations. The spectrum analyzer's 6 dB bandwidth was set to 100 kHz. The analyzer was operated in the CISPR quasi-peak detection mode for measurements of all emissions less than 1000 MHz. No post-detector video filters were used. The EUT was investigated in three orthogonal planes. There were no detectable emissions observed during the EUT's initial scan. Test Results: Because there were no detectable emissions observed during the 1-meter initial scan, the EUT was not taken to the open-area-test-site. See attached spectral plots. The EUT complied with the FCC Limits. Note: SEE ENCLOSED INITIAL FREQUENCY SCAN SPECTRAL PLOTS. The actual field intensity in decibels above one microvolt per meter (dB μ V/m) is determine by algebraically adding the measured level in dB μ V, the antenna factor (dB), and the cable loss (dB) at the appropriate frequency. FI a (dB μ V/m) = FI m (dB μ V) + AF (dB) + CL (dB) FI a = Actual Field Intensity FI m = Measured Field Intensity AF = Antenna Factor CL = Cable Loss FCC ID:AEK992249R 4 As a sample calculation, assume a particular device emits a signal with a frequency of 49.96 MHz. The received signal level is measured as 42.0 dB μ V. The total attenuation factor (antenna factor plus cable loss) for 49.96 MHz is 4.7 dB. The actual radiated field is calculated as follows: 42 dB μ V + 4.7 = 46.7 dB μ V/m In no case did the radiated emissions exceed the limits specified in Paragraph 15.109(a) of the Commission's Rules. V. POWER LINE CONDUCTED EMISSIONS MEASUREMENTS Measurements of the power line conducted emissions were not performed since the EUT has no means for connection to the public utility power grid.
