ENGINEERING STATEMENT SUPPORTING REQUEST FOR WAIVER TELEVISION STATION KSBO-CD (FACILITY ID NO. 31354) SAN LUIS OBISPO, CALIFORNIA CHANNEL 36

Background

This statement was prepared on behalf of HC2 Station Group, Inc., licensee of KSBO-CD, San Luis Obispo, CA, in support of a request for waiver of the FCC’s Phase Assignment, Testing Period, and Phase Completion Date for television station KSBO-CD in the Santa Barbara-Santa Maria-San Luis Obispo DMA*. KSBO-CD is licensed for operation on RF Channel 42 with a maximum effective radiated power (ERP) of 15 kW and an antenna height above mean sea level (AMSL) of 770.5 m.†

As a result of the FCC’s Incentive Auction repack process, the KSBO-CD facility was reassigned to RF Channel 36. KSBO-CD now holds a construction permit for operation on Channel 36 with a maximum directional ERP of 13.4 kW and an antenna height AMSL of 770.5 m.‡ An FCC engineering database summary sheet for the KSBO-CD construction permit facility is attached hereto for reference. The KSBO-CD construction permit facility is the subject early transition facility.

In coordination with the wireless carrier T-Mobile, HC2 Station Group, Inc. seeks a waiver of the FCC’s Phase Assignment, Testing Period, and Phase Completion Date to allow KSBO-CD to make the transition to Channel 36 earlier than its given phase transition date. Specifically, the target date for KSBO-CD to begin operations on Channel 36 is April 12, 2019. This will facilitate the early deployment of new 600 MHz band wireless broadband services.

This statement demonstrates that the KSBO-CD facility can transition to Channel 36 before its assigned phase date without any disruption to the FCC’s transition plans. Specifically, it is demonstrated that the operation of KSBO-CD on Channel 36 will

have no adverse interference consequences, either caused or received, under the current allocation environment.

Assigned Phase

KSBO-CD is assigned to transition Phase 8, with a testing begin date of January 18, 2020. This is based on the latest FCC Phase Assignment spreadsheet dated September 13, 2018.

Linked Station Sets and Linked Station Neighbor Stations

An inspection of the latest FCC Linked Station Set (LSS) and Linked Station Neighbor (LSN) spreadsheet databases indicates that the KSBO-CD facility is not part of any LSSs or LSNs. These are based on the latest LSS and LSN spreadsheets available from the FCC, both dated July 27, 2018.

Interference Caused Analysis Under Current Allocation Environment

An interference analysis was conducted for the KSBO-CD Channel 36 facility utilizing the latest version§ of the FCC’s TVStudy coverage and interference analysis prediction software. The report of the results is attached hereto entitled ‘Interference Caused Analysis for KSBO-CD Channel 36 Construction Permit Facility Under Current Allocation Environment.’

The results of the analysis indicate that the proposal meets the 0.5% permissible interference level with respect to interference caused to all other full-service and Class A television stations.

Interference Received Analysis Under Current Allocation Environment

An interference analysis specifically for the ‘received case’ of interference was conducted for the KSBO-CD Channel 36 early transition facility utilizing the FCC’s TVStudy prediction software. The report of the results is attached hereto entitled ‘Interference Received Analysis for KSBO-CD Channel 36 Construction Permit Facility

§ TVStudy Version 2.2.5 du Treil, Lundin & Rackley, Innc.

Under Current Allocation Environment.’ The purpose of this study is to evaluate all current environment records in the received interrference analysis.

The results of the analysis indicate that there are no cases of incoming (received) interference exceeding the permissible 0.5% interference level to the KSBO-CD Channel 36 early transition facility.

Effects on Linked Station Sets

It has been determined that the early transition of the KSBO-CDD facility to Channel 36 in advance of its phase transition date will not create any pairwise interference cases or new linked station sets.

Conclusion

It is concluded that the early transition of the KSBO-CD facility on Channel 36 as described herein, will not result in any interference caused or received cases that would result in the creation of any new linked station seets or depenndencies established in the Incentive Auction repack process.
