H78KPIATS100 VHF transmitter in quantity, for use under FCC RULES PART 22 & 90. 2.983 (d) TECHNICAL_DESCRIPTION (1) Type of Emission: 10K0F3E & 10K0F2D For 25KHz 10K0F3E & 10K0F2D For 12.5KHz For 25KHz Bn=2M+2DK M = 3000 D = 2.0KHz (Peak Deviation) K=1 Bn = 2(3.0K) + 2(2.0K)(1) = 6.0K + 4.0K = 10.0K ALLOWED AUTHORIZED BANDWIDTH = 20.00KHz. For 12.5KHz Bn=2M+2DK M = 3000 D = 2.0KHz (Peak Deviation) K=1 Bn = 2(3.0K) + 2(2.0K)(1) = 6.0K + 4.0K = 10.0K ALLOWED AUTHORIZED BANDWIDTH = 11.25KHz. 90.209(b)(5) (2) Frequency Range: 148-174 MHz (3) Power Range and Controls:There are NO user Power controls. (4) Maximum Output Power Rating: 2.0Watts, into a 50 ohm resistive load. (5) DC Voltages and Current into Final Amplifier: POWER INPUT FINAL AMPLIFIER ONLY Vce = 13.2 Volts Ice = 0.51 A. Pin = 6.70 Watts (6) Function of each electron tube or semiconductor device or other active circuit device: APPLICANT: KP ELECTRONICS INC. FCC ID: H78KPIATS100 REPORT NO.: F:\CUS\K\KP\KP145U8.RPT PAGE #: 1 2.983(d) (7) Complete Circuit Diagrams: The circuit diagram is included as EXHIBITS 4-7. (8) Instruction book. The instruction manual is in- cluded as Exhibits 3A-3B. (9) Tune-up procedure. The tune-up procedure is given in Exhibits 10A-10D. (10) Description of all circuitry and devices provided for determining and stabilizing frequency is included in the circuit description in the instruction manual. 2.983 (11) Description of any circuits or devices employed for suppression of spurious radiation, for limit- ing modulation, and for limiting power. In addition to the interstage filtering the multi section low pass filter made up of L13, L14,L15, L16, C96, C89, C97, C90, & C94. Limiting Modulaton: The transmitter audio limiting circuitry is con- tained in the loop filter U6. Limiting Power: There is no provision for limiting power. (12) Digital modulation. This unit does NOT use digital modulation, it uses 900 & 1500Hz in the AFSK transmission of data in addition to the voice. 2.983(e) The data required by 2.985 through 2.997 is submitted below.

RF power is measured by connecting a 50 ohm, re- sistive wattmeter to the RF output connector. With a nominal battery voltage of 13.6V, and the trans mitter properly adjusted the RF output measures: POWER HIGH INPUT POWER: (13.2V)(0.51A) = 6.73 Watts OUTPUT POWER: 2.0 Watts Efficiency: 29% /-----------\ /---------\ |Transmitter|---------------------|50 ohm | |under test | |Resistive| \-----------/ |Wattmeter| | \---------/ /-----------\ |Power | |Supply | \-----------/ 2.987(a) Voice Modulation_characteristics: AUDIO_FREQUENCY_RESPONSE (a) See Exhibit 15. 2.987(a) AUDIO_LOW_PASS_FILTER The audio low pass filter is included and the plot is Exhibit 17. Rules 90.210(b,d, & e) for mobile stations with a low pass filter. 2.987(b) Audio_input_versus_modulation A plot of the audio input versus deviation is shown in Exhibit 16.

On any frequency removed from the assigned frequency by more than 100%, but not more than 250%: At least 35dB. On any frequency removed from the assigned frequency by more than 250%, of the authorized bandwidth: At least 43+log(P)dB. 90.210( d) 12.5KHz channel bandwidth equipment. For transmit- ters de signed to operate with a 12.5KHz channel bandwidth, any emission must be attenuated below the power (P) of the highest emission contained within the authorized bandwidth as follows; (1) On any frequency from the center of the authorized bandwidth f0 to 5.625kHz removed from fP0: Zero dB. (2) On any frequency removed from the center of the authorized bandwidth by a displacement frequency(fd-2.88kHz)dB. (3) On any frequency removed from the center of the authoriz…
