We further request certification for analog operation and digital operation under Rule Part 27. The OET electronic filing site does not accommodate more than one modulation, power, or frequency ranges which are applicable under multiple rule parts for bands that are in transition. This transmitter may be utilized for analog video, digital video, or data transmission in systems using both pre and post transition band plans. As such, customers desire the flexibility to adjust their systems during the transition process and desire a product with the design flexibility to do so. Said customers contemplate using the transmitter for operation in existing ITFS and MMDS systems and also for new EBS and BRS operations under Part 27 in the MBS, LBS, and UBS. We request that the grant include the following specifications. Rule Part Frequency Frequency Emission Output Range Tolerance Designator Power 27 2500-2686 MHz 1000 Hz 5M75C3F 100 Watts (Peak Visual)) 27 2500-2686 MHz 1000 Hz 250KF3E 5 Watts (Average Aural) 27 2500-2690 MHz 1000 Hz 6M00D7W 25 Watts (Average) The test report filed under this application will demonstrate that the HSD-2500 complies will all relevant rules for digital and analog operations Part 27. Thank you in advance for your understanding and cooperation. Please contact me if you need additional information or clarification of items in our filing. Sincerely, James A. Yard, CEO

Figure 4-1: Test Setup for Analog Power Measurement The HSD-2500, modulated with color bars at 87.5%, was adjusted to obtain a 100 Watt Peak Visual (50dBm) and 5 Watt Aural (-13dB) measurement on the spectrum analyzer. The metering circuit was adjusted to obtain a 100% reading on the forward power meter. With the transmitter properly configured for analog operation and the peak visual power set to 200 Watts, all required tests were performed and the analog operation test data recorded in the following sections of the test report. The peak power measurement is shown in the spectrum analyzer plot in Figure 4-2.
