APPLICANT: COBRA ELECTRONICS CORPORATION FCC ID: BBOPR900DX DATE: APRIL 19, 2001 REPORT #: C\COBRA\432AK1\432AK1RPT.doc PAGE #: 1 2.1033(c)(10) Complete Circuit Diagrams: The circuit diagram is included as EXHIBIT 5 of this report. The block diagram is included as exhibits 4 of this report. 2.1033(c)(11) A photograph or a drawing of the equipment identification label is included as exhibit No. 1. 2.1033(c)(12) Photographs(8"X10") of the equipment of sufficient clarity to reveal equipment construction and layout, including meters, labels for controls, including any view under shields. See exhibits 3a-3f. 2.1033(c)(13) Digital modulation is not allowed. 2.1033(c)(14) The data required by 2.1046 through 2.1057 is submitted below. 95.639 Power Output shall not exceed 50.0 Watts effective radiated power. There can be no provisions for 95.649 increasing the power or varying the power output. 2.1046(a) RF power is measured by connecting a 50 ohm, resistive watt meter to the RF output connector. With a nominal battery voltage of 8.4 V, and the transmitter properly adjusted the RF output measures: OUTPUT POWER: 2 Watts 2.1046(a) RF power output. The test procedure used was TIA/EIA-603 S2.2.1.

The audio frequency response curve is shown as Exhibit 10. The audio signal was fed into a dummy microphone circuit and into the microphone connector. The input required to produce 30 percent modulation level was measured. 2.1047(b) Audio input versus modulation The audio input level needed for a particular per- percentage of modulation was measured in accor- dance with TIA/EIA Specification 603. The audio input curves versus modulation are on the following pages. Curves are provided for audio input frequen- cies of 300, 1000, and 3000 Hz. See Exhibits 9A-9C. 95.637 Post Limiter Filter Each GMRS transmitter, except a mobile station transmitter with a power of 2.5Watts or less, must be equipped with an audio low pass filter. At any frequency between 3 & 20KHz the filter must have an attenuation of 60log (f/3) greater than the attenuation at 1KHz. See Exhibit 8. 2.1049 Occupied bandwidth: 95.635(b)(1)(3)(7) At least 25dB on any frequency removed from the center of the authorized bandwidth by more than 50%up to and including 100% of the authorized bandwidth. At least 35 dB on any frequency removed from the center of the authorized BW by more than 100% up to and including 250% of the authorized BW. At least 43+log10(T) on any frequency removed from the center of the authorized bandwidth by more than 250%. The plots are shown on pages 4 and 5. REPORT #: C\COBRA\432AK1\432AK1RPT.doc PAGE #: 3 2.1051 Spurious emissions at antenna terminals(conducted): The following data shows the level of conducted spurious responses at the antenna terminal. The test procedure used was TIA/EIA 603 S2.2.13 with the exception that the emissions were recorded in dBc. The spectrum was scanned from 0.4 to at least the 10th harmonic of the fundamental. Method of Measuring Conducted Spurious Emissions 2.1051 Spurious emissions at the Antenna Terminals NAME OF TEST: SPURIOUS EMISSIONS AT ANTENNA TERMINALS REQUIREMENTS: Emissions must be 43 +10log(Po) dB below the mean power output of the transmitter. HIGH POWER 43…
