A draft copy of the instruction manual is included as EXHIBIT 10. 2.1033(c) (4) Type of Emission: 10K0F3E 95.629 Bn = 2M + 2DK M = 3000 D = 2.2K Bn = 2(3.0)+2(2.0) = 10.0K Authorized Bandwidth 12.5KHz 2.1033(c)(5) Frequency Range: 1. 462.5625 8. 467.5625 95.627 2. 462.5875 9. 467.5875 3. 462.6125 10. 467.6125 4. 462.6375 11. 467.6375 5. 462.6625 12. 467.6625 6. 462.6875 13. 467.6875 7. 462.7125 14. 467.7125 MHz 2.1033(c)(6)(7) Power Output shall not exceed 0.500Watts effective 95.637 radiated power. There can be no provisions for 95.647 increasing the power or varing the power. The Maximum Output Power Rating: 500 milliWatts effective radiated power. 95.645 The antenna is an intergral part to the unit, it cannot be removed without rendering the unit inoperative. In order to remove the antenna the case must unscrewed, then the PCB assemblies must be removed then the antenna can be removed. 2.1033(c)(8) DC Voltages and Current into Final Amplifier: FINAL AMPLIFIER ONLY Vce = 4.5 Volts DC Ice = 0.12A. Pin = 0.54 Watts 2.1033(c)(9) Tune-up procedure. The tune-up procedure is included 9A-9B.

The block diagrams are included as EXHIBIT 5 of this report. 2.1033(c)(11) A photograph or a drwaing of the equipment identifica- tion label is included as exhibit No. 2. 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. 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. 2.1046(a) RF_power_output. 95.637 RF power is measured by measuring the radiated power at 3 meters and then replacing the transmitter with a signal generator to determine the effective radiated power. The ERP shall not exceed 0.500 Watts. MEASURED POWER OUTPUT = 500 milliWatts ERP R.F.

FCC ID: MUDKF-2100 REPORT #: T:\CUS\K\KACE\KAC96A0\96A0.RPT PAGE #: 2 2.1047(a)(b) Modulation_characteristics: AUDIO_FREQUENCY_RESPONSE The audio frequency response was measured in ac- cordance with TIA/EIA Specification 603. The audio frequency response curve is shown on the next page. 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. 95.635(b) Post Limiter Filter The filter must be between the modulation limiter and the modulated stage. At any frequency between 3 & 20KHz the filter must have an attenuation of 60log (f/3) greater tha the attenuation at 1KHz. see the proceeding page. 2.989(c) EMISSION BANDWIDTH: 95.633(b)(1)(3)(7) Data in the plots shows that the sidebands from greater than 50% to 100% of the authorized bandwidth must be attenuated by at least 25dB and from 100 to 250% the sidebands must be attenuated by at least 35dB. Beyond 250% the sidebands must be attenuated by at least 43+log10(TP). The transmitter was modulated with 2500 Hz, adjusted for 50% modulation plus 16 dB. The spectrum analyzer was set with the unmodulated carrier at the top of the screen. The test procedure diagram and occupied bandwidth PLOTS follow. APPLICANT: KACE ELECTRONICS (ASIA) INC.
