March 19, 2008 FCC Office of Equipment Authorization To Whom It May Concern: ATTESTATION STATEMENT I hereby certify the measurements and test results were made and recorded in accordance with accepted engineering practices and do constitute an accurate representation of the product performance of the documented MIZAR 30 transmitter. Signed, President

March 22, 2008 THEORY OF OPERATION—MIZAR 30 The overall theory of operation for the MIZAR30 is provided on this page. Detailed theory of operation is outlined in the technical manual for each major sub-assembly (synthesizer, power amplifier, etc.) The audio signals comprised of left and/or right channel audio, and any subcarrier generator audio are fed to the mother board and the coder board. These two boards contain the necessary pre-emphasis and stereo encoding as required for the audio signal employed. The composite audio signal is then fed to a limiter to prevent overmodulation and sent to the voltage controlled oscillator (VCO). The VCO creates a linear FM waveform on the actual RF channel to be transmitted as programmed by the synthesizer. The synthesizer generates the proper frequency for the designated frequency channel and it uses a temperature compensated crystal controlled oscillator to control the carrier frequency to the prescribed FCC frequency tolerance. Once on the correct frequency, the RF driver amplifies the RF signal to a level that can drive the RF power amp. The RF power amp receives the RF signal from the driver and amplifies the signal to 30 watts. At the output of the RF PA, a filter is employed to prevent harmonics from reaching the output connector. Each one of the subassemblies mentioned in this paragraph uses a DC voltage. The DC voltages are generated by the switching power supply that receives its control signal from the controller assembly. The controller assembly provides a user interface and sends the appropriate voltages to the various subassemblies to program the correct mode of operation, the frequency of operation, the output power level, engages the cooling fan, etc. The controller also monitors specific parameters of the subassemblies and displays that information as selected from the front panel.

TEST REPORT ELETTRONIKA S.r.l FM TRANSMITTER TECHNICAL REPORT INTRODUCTION The following information is provided to verify the technical performance of the MIZAR 30 FM transmitter. The following information is supplied for FM broadcast service according to applicable portions of Part 2 and Part 73 of the FCC rules and regulations 1. Power Output Measurements as indicated by FCC Rule Part 2.1046 and 73.267. 2. Frequency stability measurements associated with variations in ambient temperature and with variations in line voltage as specified by 73.1545. 3. Occupied BW of the FM signal as specified by FCC Rule Part 73.297, 73.317, 73.322, and 73.1570. 4. Measurement of conducted harmonics and spurs outside its assigned channel as specified by FCC Rule Part 73.317. 5. Demodulated Amplitude versus Frequency response measurements of the transmitter compliant with the Engineering charts identified in 73.333. 6. Measurement of cabinet radiation of spurs and harmonics as specified in FCC Rule 2.1053 and 2.1057. 7. Measurements of voltage and current to final amp stage as outlined in FCC Rule 2.1033. Measurements were conducted at power output levels of 30 watts and 7.5 watts and constitute the range of power for which type certification is sought. FIGURE 1--TEST EQUIPMENT CONFIGURATION The test equipment used for the measurements is listed at the back of this exhibit. All test equipment had been calibrated prior to the use of the equipment by the supplier of the test equipment. RF Power Output Stability vs Line Voltage The equipment was configured as shown in Figure 1. The loss through the RF output cable and directional coupler and attenuator was calibrated at the carrier frequency of 98 MHz. The audio generator was not energized. The transmitter was energized at room temperature at an initial power output of 30 watts. Power was read on the Bird 4391A Power Meter and a reference level was established on the Advantest R131 Spectrum Analyzer. The line voltage was varied from 94 volts to 126 volts using a variac to adjust the voltage. The test was repeated at an output power of 7.5 watts. The data is tabulated on the next page.

The loss through the RF output cable and directional coupler and attenuator was calibrated at the carrier frequency of 98 MHz. The audio generator was not energized. The transmitter was energized at room temperature at a power output of 30 watts. Power was read on the Bird 4391A Power Meter and a reference level was established on the Advantest R131 Spectrum Analyzer. Next the temperature was varied from 0 C to +50 C. Data at the extreme temperature limits and at room temperature was recorded regarding power output. The transmitter was adjusted to 7.5 watts and the procedure was repeated. FRQUENCY STABILITY The equipment was configured as shown in Figure 1. The loss through the RF output cable and directional coupler and attenuator was calibrated at the carrier frequency of 98 MHz. The audio generator was not energized. The transmitter was energized at room temperature at a power output of 30 watts. Power was read on the Bird 4391A Power Meter and a reference level was established on the Advantest R131 Spectrum Analyzer. The line voltage was varied from 94 volts to 126 volts. The output frequency was read on the spectrum analyzer with the counter mode engaged. The results are tabulated below.

Below 25dBc => Pass Markers at 240kHz from the carrier. Below 35dBc => Pass Markers at 600kHz from the carrier. Below (43+10logP)= 58 dBc => Pass 5 Marker more than 10MHz from the carrier. Below (43+10logP)=58dBc => Pass As can be seen in the above graphs, in the mono and stereophonic modes, the emissions meet the requirements as outlined in FCC Rule 73.317. The rule stipulates emissions between 120 kHz and 240 kHz from the carrier frequency are -25 dB or better, emissions between 240 kHz and 600 kHz from the carrier are -35 dB or better, and emissions greater than 600 kHz from the carrier are at least 43 + 10 log P o , or -58 dB referenced to the unmodulated carrier (top of the screen for these graphs). PILOT FREQUENCY AND 38 kHz LEVEL The frequency of the pilot tone was measured to be 19.000 kHz. Its deviation was set at 7.5 kHz, using the FMAB. The deviation of the subcarrier of the pilot tone (38kHz) must be no more than 0.75kHz. This is measured by means of the FMAB, and confirmed by using the spectrum analyzer in order to display the subcarrier level. The photo below demonstrates the frequency to be 37.98 kHz and the amplitude is 43.5 dB relative to the pilot frequency. 6 CONDUCTED HARMONICS Conducted harmonics are sampled in the output transmission line and converted to the corrected value (using the directional coupler coupling value and cable loss) and then compared to the power output of the unit under test. The correction factor and measured level are used to find the actual l…

MIZAR 30 SUPPLEMENTAL TEST DATA FREQUENCY STABILITY VS TEMPERATURE PERFORMANCE The equipment was configured as shown in Figure 1 of the test report block diagram with the transmitter enclosed within a temperature chamber. The loss through the RF output cable and directional coupler was calibrated at the carrier frequencies of 98 MHz. The audio generator was not energized. The transmitter was energized at room temperature at a power output of 30 watts. Power was read on the Bird 4391A Power Meter and a reference level was established on the Advantest R131 Spectrum Analyzer. The temperature was then varied from +50 °C to 0 °C per FCC rule 2.1055 (a) (3) and the frequency was measured with spectrum analyzer. The temperature was allowed to stabilize at each one of the measurement points. The output frequency was read on the spectrum analyzer with the counter mode engaged. The results meet the FCC tolerance requirements outlined in 73.1545 and are tabulated below.
