The data presented on figures 1 and 2 demonstrates compliance with the appropriate technical standards. 3. OCCUPIED BANDWIDTH - Paragraphs [2.1049, 90.211(a)] Figures 3 and 4 contain pictures taken from a Hewlett Packard 8558B Spectrum Analyzer. The transmitter was modulated with a sine wave tone at 2500 Hz at a level 16 dB above the required to produce 50% modulation at the frequency maximum response. Paragraph 90.210(d) requires that the mean power of emissions shall be attenuated below the mean output power of the transmitter by the following amounts: -- On any frequency removed from the center of the authorized bandwidth f0 to 5.625 khz removed from f0; Zero db. -- On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in khz) of more than 5.625 khz but no more than 12.5 khz. At least (fd – 2.88khz)db. -- On any frequency removed from the center of the authorized Bandwidth by a displacement frequency (fd in khz) of no more than 12.5 khz. At least 50 + log(P) or 70db, whichever is the lesser attenuation. 4. SPURIOUS EMISSIONS AT THE 50 OHM TEST POINT ON THE TRANSMITTER [2.1053, 90.209 Emission Mask D] The transmitter was modulated per paragraph 2.1053. The spectrum was checked with the spectrum analyzer from 10 MHz to the 10th harmonic of the carrier frequency. Observed emissions not reported are attenuated more than 20 dB below the permissible value of 40 dB, i,e., 50 + log (.50W) = 47 dB given by Section 90.209. The data in Table 1 verifies that the test sample complies with Paragraph 90.209(c)(3).

To: Stan Lyles, FCC Applications Processing Branch From: Jeff Olson, Engineer, Tactical Technologies Inc. Date: November 1, 2002 Sub: Your correspondence: REF: 24122 FCCID: IP9751V Mr Lyles: Here are the answers to the 3 questions you asked us. Thanks in advance. ---------------------Æ 1.) Thank you for correcting this for us. 2.) Rf Power Output Measurement The output power was measured with a Hewlett Packard Microwattmeter at the RF terminal of the transmitter. The electrical characteristics of the RF load were 50 ohms resistive. A 30 dB pad was inserted between the RF terminal of the transmitter and the wattmeter to avoid overloading the wattmeter. The RF power output measured .50 Watt at 9.0 Vdc. 3.) Field Strength Of Spurious Radiation 2.1053 and 90.209 Conditions: Battery Power: 9volt dc Battery Radiation into antenna - Table 2 Minimum Standard: Part 2.1053 The power of any emission shall be attenuated below the carrier power (P) by at least (50 + 10log P) dB or 70dB, whichever is the least attenuation. Calculation of Radiated Power Limit: The emissions limit is the equivalent power that would have to be fed into a dipole antenna in order to produce the same electric field strength. E = (49.2 P)1/2 / R Where: E = electric field intensity V/m P = power in watts R = distance in meters For this case E = 1.65 V/m = 124.4 dBuV/m Attenuation Requirement: Part 2.1053 requires that the spurious radiated emissions is attenuated at least (50 + 10log (.5) = 47 dB below the unmodulated carrier field strength. The limit @ 3m = 124.4 – 47dB = 77.4 dBuV/m TABLE 2 Spurious Radiated Emissions Radiation into Antenna Generator Ant.

Test Result: The strongest spurious emission was the second harmonic of 173.9 MHz test frequency with a level of 64 dBuV/m @ 3m. This is 13.4 dB below the limit, and 50 dBc. Radiated Spurious Emissions: TIA/EIA-603-A-2001 2.2.12 The radiated spurious emissions was measured from the transmitter transmitting into a antenna which was placed on a table 3 meters away from the test antenna. Each spurious frequency that was recorded was taken by raising the test antenna from 1 to 4 meters until the maximum reading was obtained. The transmitter was then replaced with a substitution antenna, which was fed from a Rf Signal Generator. The output power of the generator was adjusted to match the transmitters radiated emission at that frequency and antenna height.
