(Model number CST802VI), is a 1 channel, .2 watt VHF FM synthesized voice transmitter for law enforcement use. The operating frequency is only a 4 Mhz section from 150 – 174 Mhz due to the narrow band antenna. The unit utilizes an internal antenna and a single internal microphone for transmitter operations. The CST802VI can be equipped with an optional scrambler for added transmitter security. Figure 1, The CST802VI Transmitter © TTI Law Enforcement ONLY CST802VI – User Guide, 1.0.3 Introduction © TTI Law Enforcement ONLY Operating Frequencies The frequencies available on the CST802VI are spaced in 12.5 kHz steps beginning with 150.0000 MHz and ending with 174.0000 MHz. Simply put, “12.5 kHz steps” means your frequency must be in any of the following configurations: xxx . x000 xxx . x125 xxx . x250 xxx . x375 xxx . x500 xxx . x625 xxx . x750 xxx . x875 This gives the CST802VI the ability to transmit on any one of 280 available frequencies. Any other frequency selection will result in an error message. Citation Receivers Any of Tactical Technologies Inc. Citation Receiver/Recorder kits (Series 20 and higher) are able to program frequency, power, and scrambling settings into the CST802VI. A special Citation Interface Cable, is supplied with the CST802VI for such an application. See your TTI representative for more information. If you already own a Citation 20 or higher receiver, programming instructions are found in the Citation Operators Manual. © TTI Law Enforcement ONLY CST802VI – User Guide, 1.0.3 Introduction © TTI Law Enforcement ONLY Range of the CST802VI Transmitter It is impossible to state absolutes about how far an RF transmitter like the CST802VI will transmit. Many variables affect the range of a device including buildings, trees, weather, construction materials, installation, etc. All things being perfect (meaning transmissions are outdoors over flat terrain with no obstructions), a .2 watt CST802VI should be able to easily transmit over a ¼ mile. You should expect less distance than that however, in a real world operation. One of the most important variables, and one that the operator can actually control, is the placement of the receiver and the receiving antenna. A good rule to follow is the higher the antenna placement, the better chance you have of quality reception. This alone will increase your operating range. Just having the CST802VI in an ideal location is not enough. © TTI Law Enforcement ONLY

RF POWER OUTPUT - Paragraphs [2.1046(a),2.1033(c)(8),90.205(d)] Power output measurements were made at the RF connector. This test was done with an unmodulated carrier in accordance with part 90.205(d) The power output was measured with a Spectrum Analyzer with a series 30 dBm pad. The electrical characteristics of the RF load was 50 ohms 0j. The RF power output was measured from 170 Mhz – 174 Mhz The RF output power did not vary with changes in the supply voltage, due to the system regulation.

OCCUPIED BANDWIDTH - Paragraphs [2.1049, 90.210] Figures 3 and 4 contain pictures taken from a 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. Part 90.210 Emission Mask D Part 90.210 Emission Mask D 4. SPURIOUS EMISSIONS AT THE 50 OHM TEST POINT ON THE TRANSMITTER [2.1053, 90.210 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 +10log (.20W) = 43 dB given by Section 90.210. The data in Table 1 verifies that the test sample complies with Paragraph 5. FIELD STRENGTH OF SPURIOUS RADIATION - Paragraphs [2.1053, 90.210] Measurements were made on the three meter range maintained by Radiation Science Inc. to quantify spurious emission level that] are radiated directly from the cabinet, control circuits, power leads and intermediate circuit elements under normal conditions of installation and operation. Particular attenuation was paid to harmonics of the carrier frequency as well as those frequencies removed from the carrier by multiples of the oscillator frequency. Data is submitted in Table 2 showing the magnitude of harmonics and other spurious emissions from 30 MHz through the 10th harmonic. The test sample was placed on a non-conductive table one meter above the ground plane in order to determine the maximum level at each emission. Both horizontal and vertical site antenna polarization were employed. The antenna was raised 1 to 4 meters in height and the equipment under test was rotated 360 degrees to minimize the emission. The reference level for spurious radiation was taken as an ideal dipole excited by the measured output power according to the following relationship: E = (49.2 P)1/2 / R Where: E = electric-field intensity in Volts/meter P = transmitted power in Watts R = distance in meters For this case: E = 1.81 V/M = 124.8 dBuv/m The permissible value of spurious emissions is equal …
