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 INCLUDED IN USER'S MANUAL. APPLICANT: MUSICAL ELECTRONICS LTD.

FCC ID: AUIFRS-100 REPORT #: T:\CUS\M\MUSICAL\MUS46AK0\MUS46A0.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. See exhibit 9. 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 Exhibit 10A-10C. 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 exhibit 11. 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 mo…
