ENGINEERING STATEMENT For Certification of COBRA ELECTRONICS CORPORATION Model No. PR-2000WX FCC ID: BBOPR2000WX I am an Electronics Engineer, a principal in the firm of Hyak Laboratories, Inc., Springfield, Virginia. My education and experience are a matter of record with the Federal Communications Commission. Hyak Laboratories, Inc. has been authorized by Cobra Electronics Corporation to make certification measurements on the PR-2000WX transceiver. These tests were made by me or under my supervision in our Springfield laboratory. Test data and documentation required by the FCC for certification are included in this report. The data verifies that the above mentioned transceiver meets FCC requirements and certification is requested. _________________________ Rowland S. Johnson Dated: June 15, 2000 A. INTRODUCTION The following data are submitted in connection with this request for type acceptance of the PR-2000WX transceiver in accordance with Part 2, Subpart J of the FCC Rules. The PR-2000WX is a hand-held, battery operated, UHF, frequency modulated, 3 W transceiver intended for voice communications applications in the 462.5500 - 462.7250 MHz band under Part 95 in the GMRS service. B. GENERAL INFORMATION REQUIRED FOR TYPE ACCEPTANCE (Paragraph 2.983 of the Rules) 1. Name of applicant: Cobra Electronics Corporation 2. Identification of equipment: FCC ID: BBOPR2000WX a. The equipment identification label is submitted as a separate exhibit. b. Photographs of the equipment are submitted as separate exhibits. 3. Quantity production is planned. 4. Technical description: a. 16k0F3E emission b. Frequency range: 462.5500-462.7250 MHz. c. Operating power of transmitter is fixed at the factory at 3 watts. d. Maximum power permitted under FCC Part 95 (interstitial) is 5 watts ERP. The PR- 2000WX fully complied with that power limitation. d. The dc voltage and dc currents at final amplifier: Collector voltage: 8.9 Vdc Collector current: 0.55 A f. Function of each active semiconductor device: See Appendix 1. g. Complete circuit diagram is submitted as a separate exhibit. h. A draft instruction book is submitted as a separate exhibit. i. The transmitter tune-up procedure is submitted as a separate exhibit. 2 B. GENERAL INFORMATION (continuted) j. A description of circuits for stabilizing frequency is included in Appendix 2. k. A description of circuits and devices employed for suppression of spurious radiation and for limiting modulation is included in Appendix 2. l. Not applicable. 5. Data for 2.985 through 2.997 follow this section. C. RF POWER OUTPUT (Paragraph 2.985(a) of the Rules) RF power output was measured with a Bird 4421 RF power meter and a Narda 765-20 attenuator as a 50 ohm dummy load. Maximum power was 2.6 watts. (The transmitter was tuned by the factory.) D. MODULATION CHARACTERISTICS 1. A curve showing frequency response of the transmitter is shown in Figure 1. Reference level was audio signal output from a Boonton 8220 modulation meter with one kHz deviation. Audio output was measured with an Audio Precision System One TRMS voltmeter and tracking generator. 2. Modulation limiting curves are shown in Figure 2, using a Boonton 8220 modulation meter. Signal level was established with an Audio Precision System One. The curves show compliance with paragraphs 2.987(b) and 95.633(b). 3. Figure 3 is a graph of the post-limiter low pass filter which meets the requirements of paragraph 95.633(b) in providing a roll-off of 60Logf/3 dB where f is audio frequency in kHz. Measurements were made following EIA RS-152B with an Audio Precision System One on the Boonton 8220 modulation meter audio output. 4. Occupied_Bandwidth (Paragraphs 2.989(c), 90.209(b)(4), and 95.629(a) of the Rules) Figure 4 is a plot of the sideband envelope of the transmitter output taken with a Tektronix 494P spectrum analyzer. Modulation corresponded to conditions of 2.989(c)(1) and consisted of 2500 Hz. 3 C. MODULATION CHARACTERISTICS (continued) tone at an input level 16 dB greater than that necessary to produce 50% modulation at 2149 Hz, the frequency of maximum response. Measured modulation under these conditions was 3.2 kHz. The plot is within the limits imposed by Paragraph 90.211(h) for frequency modulation. The horizontal scale (frequency) is 10 kHz per division and the vertical scale (amplitude) is a logarithmic presentation equal to 10 dB per division. 5.
