BOIDVFAtlas Mobile Digital Television Transmitter

HARRIS CORPORATION Broadcast Communications Division 3200 Wismann Lane Post Office Box 4290 Quincy, IL USA 62305-4290 telephone 1-217-222-8200 www.harris.com March 21, 2007 Compliance Certification Services 47174 Benicia Street Fremont, CA 94538 Attn: Mr. Mike Kuo Dear Mike, This letter and the accompanying test report and documents are in application for FCC Certification of a series of Digital Television transmitters to be operated under the requirements of FCC Part 27.53 (f). Three models of the ATLAS Mobile DVF series of transmitters are included in this application, with power output ratings from 900 watts to 3400 watts, before the output filter. 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 ATLAS Mobile DVF 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 900 watts to 3400 watts at the cabinet output connection. The number of PA (Power Amplifier) modules used is governed by the power output of each model. 2 PA modules are used in the DVF900 transmitter, 4 modules in the 1700 watt DVF1700 and 8 modules in the 3400 watt DVF3400. A single cabinet houses all models up to and including the DVF3400. Larger transmitters are intended using multiple cabinets, and these will be the subject of future applications for Certification. 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 Part 27.53 (f). Tests were conducted on a single 3400 watt model, the DVF3400. A front and rear photo on page 8 of 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 ATLAS Mobile product, under the required Certification method. We respectfully request these products be certified. Yours sincerely, Karl Black Compliance Engineer Harris Broadcast Communications (217) 221-7543

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. To support the requested confidentiality, we have placed the information requested to be kept confidential in Exhibits whose cover pages and whose entries in the Table of Contents are marked as described above. Sincerely, Karl Black Compliance Engineer (217) 221-7543 (office) (217) 221-7088 (fax) [email protected]

The grant will show only powers at and below what was tested. Harris understands that they will need to submit a separate filing for the higher power model(s) if/when needed. Are the remaining inquiry items considered complete so as to allow the grant to be issued? Response: The equipment as reported shows compliance, and is acceptable for grant of Certification. http://mail.google.com/mail/?view=page&name=gp&ver=sh3fib53pgpk 4/17/2007 11:39:26 AM
