Broadcast Sports Inc Model HUB97 FCC ID:KTB-HUB97 3 INTRODUCTION The HUB97 is a portable video transmitter specifically designed to meet the growing needs of the mobile television broadcast industry. The unit is TYPE ACCEPTED per CFR 47, Part 74, Subpart F and functions as a stand alone transmitter for a TV ENG station. The transmitter has 16 preset channels including those in the RF ENG 2.0 GHz. and 2.5 GHz. bands as well as 2 channels in the 2.3 GHz. band. Optionally, the device can be factory tuned to any frequency between 1999 to 2500 Mhz in 250 kHz steps in accordance with FCC specifications. The HUB97 features several capabilities which make it an ideal building block for a modular system requiring high density packaging. Four NTSC video inputs allow the user to easily switch between four video sources with no transmission delays. Additionally, a programmable audio sub carrier provides for the transmission of voice or telemetry. An RS-422 interface enables the unit to be remotely operated and provides control of all internal functions and status monitoring. The units small size and functional interface make it readily chassis mountable. HUB97 FRONT VIEW Note: When the top LED is illuminated, valid RS-422 data is being received.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 May 16, 2004 RE: FCC ID: KTB-HUB97_ATCB001346 Attention: Gregory M. Snyder I have a few comments on this Application. 1. Please provide the factory tune up procedure. 2. Please note that the emissions mask plots do not provide the frequency graticules. This makes it very difficult to determine if the mask is properly overlaid. Please provide the vertical graticules for frequency on the plot. Alternately, please clearly and accurately identify the frequencies associated with each change in mask level. 3. Please note that page 30 of the report refers to 74.637(a)(3) for radiated spurious emissions. Please note that 74.637(a)(3) is for ‘vestigial sideband AM video’. It appears that the actual paragraph reference should be 74.637(a)(1)(iii). Please verify and correct as needed.

Document 7960-MPE, Rev. 0 FCC ID: KTB-HUB97 RF Exposure Test Report Washington Laboratories, Ltd May 2004 Maximum Permissible Exposure Test Report for Broadcast Sports, Inc. FCC ID: KTB-HUB97 May 6, 2004 WLL PROJECT #: 7960 This report may not be reproduced, except in full, without the prior written consent of Washington Laboratories, Ltd. RF Exposure Test Report Document 7960-MPE, Rev. 0 FCC ID: KTB-HUB97 RF Exposure Test Report Washington Laboratories, Ltd May 2004 1 Maximum Permissible Exposure Test Report for FCC ID: KTB-HUB97 1.0 Introduction This report has been prepared on behalf of Broadcast Sports, Inc. to show compliance of the HUB transmitter with the RF exposure requirements as defined in FCC §1.1307. 1.1 Requirements Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These categories are fixed installation, mobile, and portable and are defined as follows: ƒ Fixed Installations: fixed location means that the device, including its antenna, is physically secured at a permanent location and is not able to be easily moved to another location. Additionally, distance to humans from the antenna is maintained to at least 2 meters. ƒ Mobile Devices: a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to be generally used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. Transmitters designed to be used by consumers or workers that can be easily re-located, such as a wireless modem operating in a laptop computer, are considered mobile devices if they meet the 20 centimeter separation requirement. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091. ƒ Portable Devices: a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable device requirements are found in Section 2.1093 of the FCC's Rules (47 CFR§2.1093). For this test report the Broadcast Sports, Inc HUB transmitter is classified as a mobile device. The FCC also categorizes the use of the device as based upon the user’s awareness and ability to exercise control over his or her exposure. The two categories defined are Document 7960-MPE, Rev. 0 FCC ID: KTB-HUB97 RF Exposure Test Report Washington Laboratories, Ltd May 2004 2 Occupational/Controlled Exposure and General Population/Uncontrolled Exposure. These two categories are defined as follows: ƒ Occupational/Controlled Exposure: In general, occupational/controlled exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who have been made fully aware of the potential for exposure and can exercise control over their exposure. This exposure category is also applicable when the exposure is of a transient nature due to incidental passage through a location where the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. Awareness of the potential for RF exposure in a workplace or similar environment can be provided through specific training as part of a RF safety program. If appropriate, warning signs and labels can also be used to establish such awareness by providing prominent information on the risk of potential exposure and instructions on methods to minimize such exposure risks. ƒ General Population/Uncontrolled Exposure: The general population / uncontrolled exposure limits are applicable to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general public would come under this category when exposure is not employment-related; for example, in the case of a wireless transmitter that exposes persons in its vicinity. Warning labels placed on low-power consumer devices such as cellular telephones are not considered sufficient to allow the device to be considered under the occupational/controlled category, and the general population/uncontrolled exposure limits apply to these devices. The Broadcast Sports, Inc HUB transmitter is considered to be used in a uncontrolled environment and is therefore evaluated to the General Population/Uncontrolled Exposure limits. 1.2 Radio Frequency Radiation Exposure Evaluation The highest rated RF output power of the unit is 1.5W at 1999M to 2496MHz. According to §1.1310 of the FCC rules, the power density limit for General Population/Uncontrolled Exposure in this frequency is 1mW/cm 2 . To comply with the exposure limits for this section, individuals must maintain a safe distance from the transmit antenna. The following formula was used to calculate the minimum safe distance: 2 4R PG S π = Where: S = Power Density P = Output Power at the Antenna Terminals G = Gain of Transmit Antenna (linear gain) Document 7960-MPE, Rev. 0 FCC ID: KTB-HUB97 RF Exposure Test Report Washington Laboratories, Ltd May 2004 3 R = Distance from Transmitting Antenna For this device, the calculation is as follows: S = FCC Limit = 1mW/cm 2 P = Output Power = 1500 mW G = Unity Gain = 0 dBi = INVLOG(0/10) = 1 Solving for the Power Density at 20cm: () () 2 204 11500 ×× × = π S = 0.3mW/cm 2 (Based on continuous transmission)
