Doug Rosequist Univision Communications 605 Third Avenue New York, NY 10158 January 1, 2019 Dear Doug, The letters announcing the intention of KSTR-DT to begin broadcasting using the new ATSC 3.0 broadcast transmission standard were mailed on December 13, 2018 to 1301 medical facilities within KSTR-DT / ATSC 3’s the predicted coverage area. Enclosed is a copy of the Medical Notification Letter, a list of the addresses, and proof of mailing stamped by the US Post Office in Orlando, Florida. Shortly, you will receive a package containing the undeliverable letters returned by the USPS. The average return rate is generally eight to ten percent and letters are typically returned due to: the facility relocating and forwarding has expired, the name was changed, the facility refused to accept the letter, or the operation merged or was acquired by another company. The returned letters along with the total list of facilities notified and the proof of mailing will be evidence of your sincere attempt and good faith effort to identify and notify health care operations in your coverage area. Please place these documents in your Public File. In closing, it has been a pleasure to serve you and your station, and I look forward to helping you with any other notification needs as they arise in the future. Sincerely, Lisa Sockett COO – RF Notifications MAIL_DATE Attention: Administrator or Biomedical Engineer OrgName_LBN Prac1stAddr Prac2ndAddr PracCity, PracState PracZip Referring to: KSTR-DT - Irving, TX (“KSTR-DT” or the “Station”) NOTICE OF UPCOMING MODULATION SCHEMA, CHANNEL, AND BROADCAST FREQUENCY CHANGES OF KSTR-DT THIS LETTER CONCERNS TELEMETRY OPERATION. THE RESPONSIBLE PARTY FOR OVERSEEING AND/OR MAINTAINING CLINICAL OR BIOMEDICAL ENGINEERING EQUIPMENT AT THIS FACILITY MUST RECEIVE THIS LETTER. Dear Administrator or Biomedical Engineer, KSTR-DT has retained RF Notifications, a broadcast TV consultant, to notify you of the impending changes of the Station’s digital television channel in your area. We are notifying you of this channel change because patients at your facility may use biomedical telemetry devices that operate in the television broadcast band and may be affected when this change takes place. On or about March 1st, 2019 KSTR-DT will begin broadcasting using the new ATSC 3.0 broadcast transmission standard. This new ATSC 3.0 modulation schema is based on COFDM modulation (vs. the existing 8-VSB based system). Then, as early as April 13, 2019, KSTR-DT will begin testing this new broadcast transmission standard on UHF channel 34. This testing is in preparation for full time operations on channel 34 to commence on or about Ju n e 21, 2019. During this testing phase KSTR-DT's channel 48 will remain on-air. Certain biomedical telemetry devices have been allowed to use unoccupied TV channels in their area on a secondary basis, according to the rules of the Federal Communications Commission (codified at 47 CFR 15.242 (a)(1)). If interference to or from these devices arises with regard to the TV broadcast service, the devices must cease operation on that channel. It is the responsibility of the medical facility or operator of the device to identify and retune its equipment to an alternative non-interfering channel. The purpose of this letter is to provide you information and give you reasonable opportunity to resolve any issues. It will be important for you to discuss these changes with your technology supplier, especially if there is a possibility that biomedical devices used in your facility are likely to malfunction when KSTR-DT changes TV channel operations. If you plan to replace your biomedical equipment, we urge that you purchase equipment designed to operate in the frequencies set aside for medical use. The contact information for the broadcast executive in charge of the TV station, along with the commencement date, TV channel and frequency band for each station are listed on the attached page(s). Please contact the individual listed on the attached page who is associated with the specific channel, if you wish for more information or want to report anticipated or actual interference problems. Kind Regards, Lisa Sockett, COO - RF Notifications Relevant Technical Information This notice is being sent to announce the Upcoming KSTR-DT changes. In order to prevent interruption in patient care, please review the following pertinent information for the new facilities and compare to your telemetry equipment immediately. This is the only notice you will receive.
