March 21, 2012 Timco Engineering Inc. 849 NW State Road 45 Newberry, FL 32669 Applicant: Garmin International, Inc. 1200 East 151st Street Olathe, KS 66062 Re: Confidentiality for submittal information regarding FCC ID number IPH-01443 PRODUCT: Aviation Transmitters operated under part 87 Dear Sirs: Garmin International, Inc. requests that the material in the Parts List, Schematics, Block Diagram, and Operational Description be withheld from public disclosure pursuant to Sections 0.457 and 0.459 of the Commission’s Rules following grant of the application. In support of this request, Garmin International, Inc. submits the following information. CONFIDENTIAL FILES Exhibit File Schematic Conf Schem IPH01443.pdf Block diagram Conf BlkDia IPH01443.pdf Operational Description Conf OpDesc IPH01443.pdf Parts List Conf PartList IPH01443 1.pdf Parts List Conf PartList IPH01443 2.pdf 1. Identification of the specific information for which confidential treatment is sought: The materials set fourth in the Operational Description, block diagram, parts list, and Schematics, which are segregated, from the non-confidential exhibits of the application, are those for which confidentiality is sought. 2. Identification of the Commission proceeding in which the information was submitted or a description of the circumstances giving rise to the submission: The proceeding is that involving the application for equipment authorization (certification) under FCC ID No: IPH-01443 ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 913 837-3214 3. Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged: This material includes a detailed theory of operation, circuit diagrams, and schematic. As such, this material is treated as highly confidential business information. 4. Explanation of the degree to which the information concerns a service that is subject to competition: The material for which confidentiality is sought is employed in the design and manufacture of this transmitting equipment that is offered on a highly competitive basis. Customers for this equipment have a variety of competing sources. 5. Explanation of how disclosure of the information could result in substantial competitive harm: Disclosure would, in effect, give away the fruits of the labors of Garmin International, Inc.’s engineering personnel, who have designed the equipment and the manufacturing process. Disclosure would also offer competitors additional unwarranted insight into the state of the product development, thereby allowing competitors an advantage, not available to Garmin International, Inc. 6. Identification of any measures taken by the submitting party to prevent unauthorized disclosure: The information for which confidential treatment is sought is kept confidential by Garmin International, Inc. and not made available to third parties except pursuant to non-disclosure agreements. 7. Identification of whether the information is available to the public and the extent of any previous disclosure of the information to third parties: To the knowledge of those preparing this application, the information has not been disclosed publicly heretofore. While the general theory of operation of this equipment has been the subject of numerous disclosures in industry and standards groups as well as in rule making proceedings of the FCC, the protection sought is narrowly drawn and pertains to certain specific implementations of this radio technology. 8. Justification of the period during which the submitting party asserts that the material should not be available for public disclosure: This material should not be disclosed for at least 25 years. While improvements in design are made relatively frequently, disclosure of the design information would lead to insights into both design and manufacturing techniques that could have an adverse competitive effect for many years to come. As such, it is important that the design not be made available to unauthorized persons who might attempt to use knowledge of the design to compromise the applications for which the equipment will be employed. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers

GTX 3000 TX Tune Procedure Manual Transmitter Tuning 1. Power down the unit and connect the antenna port to a Mode S / ATCRBS interrogation generator (SDX2000 or equivalent) through a cable with 1.5 ± 0.1 dB loss. 2. Set the interrogation generator for ATCRBS interrogation at 100 PRF and power level of -50 dBm. 3. Connect the UUT output from the interrogation generator to the oscilloscope input. The oscilloscope port should be set for 50 ohm impedance, or should have an external 50 ohm load connected if using a high impedance setting. 4. Refer to Error! Reference source not found. for locations of the alignment components referenced in the steps that follow. Figure Error! No text of specified style in document..1. Alignment Point Locations 5. Adjust the screws on trimmer caps C1027, C1024, C2020, C2035, C2025, and C2017 clockwise until resistance is felt, then 4 turns counterclockwise. 6. Adjust potentiometers R2012 and R2003 fully counterclockwise, then turn clockwise one quarter turn. 7. If not connected, reconnect the ribbon cable between the transmitter and main boards. 8. Turn on the unit power. 9. Using the GTX3000 SI Tool, put the unit in test mode. 10. Reply pulses should be seen on the oscilloscope. If not, adjust the scope vertical scale and / or trigger level until a stable pulse display is obtained. The actual vertical scale settings are dependent on the characteristics of the interrogation generator UUT output. 11. Adjust the horizontal scale on the oscilloscope to 200 nS per division to display a single pulse. 12. While observing the pulse on the oscilloscope, adjust trimmer cap C2017 for maximum pulse amplitude. GTX 3000 TX Tune Procedure 13. Adjust trimmer cap C2025 for maximum pulse amplitude. 14. Adjust trimmer cap C2020 for maximum pulse amplitude. 15. Adjust trimmer cap C2035 for maximum pulse amplitude. 16. Adjust trimmer cap C1024 for maximum pulse amplitude. 17. Adjust trimmer cap C1027 for maximum pulse amplitude. 18. Adjust potentiometer R2003 for maximum pulse amplitude. 19. Adjust potentiometer R2012 clockwise until a small peak is seen at the right hand edge of the pulse top as seen in Error! Reference source not found.. Figure Error! No text of specified style in document..2. Pulse Showing Trailing Edge Peak 20. Adjust R2012 counterclockwise until the small peak disappears and the pulse resembles that shown in Error! Reference source not found.. GTX 3000 TX Tune Procedure Figure Error! No text of specified style in document..3. Pulse Shape after R2012 Readjustment 21. Turn off power to the unit. 22. Install the transmitter compartment cover and turn the unit power back on. 23. Repeat steps 12 through 18 above to correct for any minor tuning errors that may be caused by the presence of the transmitter compartment cover. 24. Verify that the pulse width is (a) at least 450 nS and (b) the Transmit Pulse Width field in the SI Tool is as small as possible while still allowing the pulse width to be larger than 450 nS. The pulse width can be increased or decreased in the GTX3000 SI Tool by entering numbers 1 thru 6 in the Transmit Pulse Width field. A larger number equates to a longer pulse width. The pulse width should be set to the lowest number that gives a width greater than or equal to 450 nS. 25. Verify that power output is greater than 205 watts as measured through a 1.5 dB cable loss at the interrogation generator. 26. This completes the transmitter alignment procedure.
