August 23, 2013 To Whom it May Concern, HARRIS CORPORATION Broadcast Communications Division 3200 Wismann Lane Post Office Box 4290 Quincy, IL USA 62305-4290 www.harris.com This letter and the accompanying test report and documents are in application for FCC Certification of a series of FM transmitters to be operated under the requirements of FCC CFR 47 Parts 2 and 73. Three models of the Flexiva FAX series of transmitters are included in this application, with power output ratings from 165 watts to 55 watts. All models use the identical sub- assemblies, with the only significant difference between them being the number of output amplifier modules used to produce the required power. The Flexiva FAX series of transmitters are an advanced modular design, using the same components and assemblies in a building-block approach to create transmitters with output power ratings from a maximum 165 watts to a maximum 55 watts at the cabinet output connection. The number of PA (Power Amplifier) modules used is governed by the power output of each model. 1 PA module is used in the FAX150 (150 watts) transmitter and is software limited for the FAX50 (50 watts). Our test report intends to show that however many PA modules are used, the performance of the transmitter is well within the limits imposed by CFR 47 Parts 2 and 73 Tests were conducted on a single 165 watt model, the FAX150. A front and rear photos shown in the exhibits and in the test report give details of the various parts of the transmitter. These data are submitted in support of the application for FCC authorization of these three models of the FLEXIVA FAX Radio Transmitter product, under the required Certification method. We respectfully request these products be certified. Yours sincerely, John Harmon Compliance Engineer Harris Broadcast Communications (513)459.3804

October 29, 2013 Dear Edna Prado, Below are the responses to your latest inquiries for FCC ID: BOIFAXLP. The original email is attached on pages 2 and 3 for your reference. Inquiry 1: “1) The application states that the equipment is a software defined radio (SDR). However, no software security description was included. Confirm if this is in fact an SDR, if so provide the required documentation. For additional information on what constitutes an SDR, refer to KDB Publication 442812 D01 SDR Apps Guide v02r01. “ Harris Broadcast Response: This is not a software defined radio. This was a clerical error on the application – the selection was inadvertently checked. Inquiry 2: “2) The application states that this is a limited split module. However, limited split modules are not permitted for licensed devices. Please clarify. See 996369 D01 Module Certification Guide v01r03 for additional information. “ Harris Broadcast Response: This is a standalone FM transmitter. The limited split module selection should not have been selected. Inquiry 3: “3) The test report indicates that spurious emissions were measured in the FM-only mode. Provide an explanation on why the measurements were not made in the FM+HD mode and how compliance was confirmed.” Harris Broadcast Response: When measuring the level of an unmodulated signal its measured level will be unaffected by the measurement bandwidth of the spectrum analyzer. When modulation is applied (as in FM+HD) the signal spreads out wider than the measurement bandwidth, thus lowering the result. Hence measuring the level at the highest output power unmodulated will yield the worst case scenario.

Harris Broadcast is an independent company not affiliated with Harris Corporation. Flexiva FAX series Transmitter FCC Certification Application FCC ID: BOIFAXLP September 26, 2013 Request for Confidentiality Harris Broadcast 3200 Wismann Lane Post Office Box 4290 Quincy, IL USA 62305-4290 Pursuant to 47CFR 0.457 and 0.459, we hereby request that the following documents be held confidential: Schematics, Block Diagram, Bill of Materials/Parts List, Technical/Operational Description and Internal Photos be withheld from public inspection. Each Exhibit so-marked contains information of a proprietary nature to our company, and possibly to our customers also. Information which could be obtained from the cited Exhibits, which are commonly known as "Trade Secrets", includes printed circuit trace routing, component selection, RF circuit "broadbanding" techniques, mechanical construction layouts and modulation methods. The confidentiality of such information is carefully guarded within our company, and only shared when further disclosure is restricted by binding agreement. Additional proprietary information is contained within drawings, schematics and equipment configuration instructions, normally supplied to customers only after their purchase of the described equipment. Our customers, after having made such purchases, have no reason to share the documents with other parties and, in some cases, may be restricted from doing so by binding agreement. Additionally, those documents are normally supplied as hard copies as part of the equipment's documentation, and often in a size that is difficult to duplicate with standard office equipment. We are therefore concerned that in the event the above described information were to be made available in a public forum, particularly one as easy to access as the World Wide Web, our competitors, or those of our customers, could easily obtain and use it to compromise our ability, and that of our customers, to maintain our respective competitive positions in the marketplace worldwide. We therefore respectfully ask that you honor our request to maintain that confidentiality in regard to the selected documents. Sincerely, John Harmon Compliance Engineer 513.459.3804 (office) September 26, 2013 [email protected]
