Report #: T:\cus\M\MGT\278u0-report.doc FCC ID: O9TMTX2100 Page Number 2 Date: 3 June 2000 2.1033(c)(11) Photograph or drawing of the label showing the FCC ID and the location of the label – See Exhibit # 1. 2.1033(c)(12) Photographs completely documenting the radio – See Exhibit #’s 2A-2E. 2.1033(c)(13) N/A This is for devices that use digital modulation. 2.1033(c)(14) The data required by 2.1046 through 2.1057 follows; 2.1046(a) RF power output. The test procedure used was TIA/EIA-603 S2.2.1. RF power is measured by connecting a 50 ohm, resistive wattmeter to the RF output connec- tor. With a nominal battery voltage of 12.0V, and the transmitter properly adjusted the RF output measures: INPUT POWER: (12V)(A) = 1.80 Watts OUTPUT POWER: 100 mWatts Efficiency: 5.50% 2.1046(a) RF power output. The test procedure used was TIA/EIA-603 S2.2.1. 2.1047(a) Modulation characteristics: AUDIO FREQUENCY RESPONSE The audio frequency response was measured in accordance with TIA/EIA Specification TIA/EIA-603 S2.2.6.2.1. The audio frequency response curve is shown in Exhibit # 7. 2.1049 AUDIO LOW PASS FILTER Transmitters utilizing analog emissions and meets the requirements of paragraph 90.210(c) therefore no low-pass filter response in included.

(2) On any frequency removed from the center of the author- ized bandwidth by a displacement of (fd in kHz) of more than 10kHz but not more than 250%of the authorized bandwidth: At least 29log(fd2/11)dB. (3) On any frequency removed from the center of the author ized bandwidth by a displacement of (fd in kHz) of more than 250% of the authorized bandwidth: At least 43+ 10log(P) dB. See Exhibit 14. 2.1049 Occupied bandwidth: Using TIA/EIA 2.2.11 Spectrum TIA/EIA-603 S2.2.11 was used to measure the occupied bandwidth. Plots were made of the spectrum modulated by an NTSC generator with a full video pattern. Data in the plots show that all sidebands beyond the authorized bandwidth are less than 0.5% of the unmodulated carrier. The plots show the transmitter modulation with; The spectrum analyzer was set with the unmodulated carrier at the top of the screen. The test procedure diagram and occupied bandwidth plots follow.

Report #: T:\cus\M\MGT\278u0-report.doc FCC ID: O9TMTX2100 Page Number 4 Date: 3 June 2000 2.1051 Spurious emissions at antenna terminals(conducted): The following data shows the level of conducted spuri- ous responses at the antenna terminal. The test proce- dure 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. NAME OF TEST: SPURIOUS EMISSIONS AT ANTENNA TERMINALS REQUIREMENTS: Emissions must be 43 +10log(Po) dB below the mean power output of the transmitter. POWER OUTPUT 43 + 10log(0.1) = 33.0dB Frequency dB below MHz carrier 24250 485050.4 727550.7 970067.1 1212562.7 1455053.7 16975>80 19400>80 21825>80 24250>80 Applicant: M & G Technology, LTD.

The spectrum was scanned from 30 to the 10 th harmonic. This test was conducted per ANSI C63.4-1992 with the exception of briefly connecting the transmitter to a half wave dipole for the purpose of establishing a reference.
