EXPOSITORY STATEMENT/DESCRIPTION The Beetle R/C Transmitter (FCC ID:992249) is a crystal controlled low- powered digital transmitter. It consists of one large-scale-integrated (LSI) circuit, one crystal, RF amplifier stage, and passive switch controls. See attached block diagram. The LSI chip produces the digital baseband modulation that will be modulated onto the carrier. The carrier is produced via the crystal and RF amplifier stages. The crystal oscillator circuit is comprised of X1 (49.86 MHz) and Q1, its associated passive components. The RF signal from the oscillator circuit is modulated by the digital baseband signals at the base of the RF amplifier stage (Q2). The output of the RF amplifier is attached to the antenna via a matching circuit consisting of C6, L3, and C8 - a “pi” circuit. See attached schematic. The device operates using a single 9.0 VDC Battery. All tuning and verifications are performed by the manufacturer and no external ground is required or used with this transmitter.

(10)N/A. III. GENERAL TEST CONDITIONS AND PROCEDURES Measurement procedures were used as outlined in ANSI C63.4-92, 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 close distance to determine its emission characteristics. IV. RADIATED EMISSION MEASUREMENTS The transmitter was assembled on a rotatable wooden test stand approximately 0.8 meters in height. The transmitter's antenna was fully extended. The emission spectrum was examined up to 1000 MHz using FCC ID: AEK992249 3 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 peak detection mode for measurements of emissions less than 1000 MHz. No post-detector video filters were used. The highest emission amplitudes relative to the appropriate limit were measured and have been recorded in Table 1. All emissions not reported were more than 20 dB below the specified limit. The actual field intensity in decibels above one microvolt per meter (dBuV/m) is determined by algebraically adding the measured level in dBuV, the antenna factor (dB), and the cable loss (dB) at the appropriate frequency. FI a (dBuV/m) = FI m (dBuV) + AF (dB) + CL (dB) FI a = Actual Field Intensity FI m = Measured Field Intensity AF = Antenna Factor CL = Cable Loss As a sample calculation, assume a particular device emits a signal with a frequency of 49.86 MHz. The maximized received signal level measured as 71.4 dB μ V. The total attenuation factor (antenna factor plus cable loss) for 49.86 MHz is 4.8 dB. The actual radiated field is calculated as follows: 71.4 dB μ V + 4.8 dB = 76.2 dBuV/m or 6,456.5 μ V/m (peak) The field strength of the fundamental did not exceed 10,000 uV/m (average) at 3 meters, as specified in Paragraph 15.235. FCC ID: AEK992249 4 As per the requirements defined in 15.209(a), the radiated emission limit at the band edges is 40.0 dB μ V/m (100 μ V/m) at 3 meters. As per the attached spectral plot (Figure 1) the highest emission level at the lower band edge approximately 40 dB below the modulated carrier peak level. At the upper band edge the highest emission level is approximately 40 dB below the modulated carrier peak level. Note: Because the the EUT complies using peak detection (worst case), quasi-peak detection was not used. Based on the maximized peak radiation measurements of the carrier, these emission levels are: Lower Band Edge 76.2 dB μ V/m - 38.0 dB = 38.2 dB μ V/m (at 3 meters), or 81.3 μ V/m Upper Band Edge 76.2 dB μ V/m - 37.0 dB = 39.2 dB μ V/m (at 3 meters), or 91.2 μ V/m All other emissions were found to be in compliance with the restrictions of Paragraph 15.209(a) of the Commission's Rules. Because the emissions were below the limits using peak detection, duty cycle correction factors were not calculated. V. OCCUPIED BANDWIDTH MEASUREMENTS In order to demonstrate compliance with the band edge restrictions of Paragraph 15.235(b), the occupied bandwidth of the EUT was measured. Paragraph 15.235(b) specifies that the field strength of any emissions appearing between the band edges and up to 10 kH…
