Executive Summary
Meeting: Study session Meeting date: September 14, 2020 Written report: 7 Executive summary Title: Comcast franchise renewal update Recommended action: **Due to the COVID-19 emergency declaration, this item is considered essential business and is Categorized as Time-Sensitive** • The report is presented for information only. No action is required. Policy consideration: Is the progress on the franchise renewal in keeping with council expectations? Summary: The city’s current franchise agreement with Comcast expires in January 2021. Upon receipt of Comcast’s request to renew its cable franchise in the city, the city notified Comcast of its intent to conduct informal renewal negotiations in accordance with the federal Cable Act. To prepare for negotiations, the city evaluated Comcast’s past performance under the existing franchise and conducted a needs assessment to determine the future cable-related Public- Educational-Government (PEG) community needs and interests of the city. This is the criteria prescribed by the Cable Act. Following the conclusion of the needs assessment, the city’s cable franchise attorney developed a draft franchise agreement, which the city plans to submit to Comcast for consideration. Financial or budget considerations: The final franchise agreement will determine the franchise fee, based on a percentage of gross revenues derived from cable service and PEG (public- educational-government) capital funding to be received by the city over the next franchise term, expected to be 10 years. Strategic priority consideration: St. Louis Park is committed to creating opportunities to build social capital through community engagement.

The FCC Filing
Dr. Theodore S. Rappaport, PE PO BOX 888 Riner, Virginia 24149 [email protected] November 10, 2018 Commissioners Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Dear FCC Commissioners: This is a notice of ex parte, based on email communication I had with the CTO of the FCC, Dr. Eric Burger, on November 8, 2018, his reply on November 10, 2018, and my reply on November 11, 2018. The email communication is centered around a posting that appeared on the FCC ECFS system on November 7, 2018, and is part of an ongoing proceeding at the FCC, NPRM 16-239, that I and thousands of others view as a direct threat to the national security interests of the United States, as well as being detrimental to the hobby of amateur (“ham”) radio. Public comments made in FCC’s NPRM 16-239, and in FCC proceedings RM-11708, RM-11759, and RM-11306 proposed by the American Radio Relay League, show the vast number of rule violations and national security threats that continue to go unaddressed by the FCC. Commenters such as me view the lack of FCC acknowledgement of these problems as jeopardizing the safety of US citizens. NPRM 16-239 attempts to remove a limit on the baud rate of High Frequency (HF) shortwave transmissions, without first addressing ongoing rule violations pertaining to proper usage of the amateur radio service, the use of obscured, private messaging which is forbidden in Part 97 rules and creates national security concerns, as well as other violations. If allowed, NPRM 16-239 would perpetuate the current violations, and would authorize obscured transmissions of unlimited bandwidth over the global airwaves, further increasing the danger to our national security, since these transmissions cannot be intercepted or eavesdropped by other amateur radio operators or the FCC. -

Supplementary Notes 1 16. Abstract An investigation is made of the feasibility of developing compact transmit antennas and/or other means to efficiently couple VLF to MF band radio energy between portable wireless communication units in coal mines. The completely wireless communication ranges between two portable radios equipped with practically-sized reference loop antennas in represen- tative coal mine environments are estimated. Antenna technology is assessed with respect to transmit moment, range, intrinsic safety, battery and wearability requirements to deter- mine the most suitable antenna types for use by miners. -
Choosing a Ham Radio
Choosing a Ham Radio Your guide to selecting the right equipment Lead Author—Ward Silver, NØAX; Co-authors—Greg Widin, KØGW and David Haycock, KI6AWR • About This Publication • Types of Operation • VHF/UHF Equipment WHO NEEDS THIS PUBLICATION AND WHY? • HF Equipment Hello and welcome to this handy guide to selecting a radio. Choos- ing just one from the variety of radio models is a challenge! The • Manufacturer’s Directory good news is that most commercially manufactured Amateur Radio equipment performs the basics very well, so you shouldn’t be overly concerned about a “wrong” choice of brands or models. This guide is intended to help you make sense of common features and decide which are most important to you. We provide explanations and defini- tions, along with what a particular feature might mean to you on the air. This publication is aimed at the new Technician licensee ready to acquire a first radio, a licensee recently upgraded to General Class and wanting to explore HF, or someone getting back into ham radio after a period of inactivity. A technical background is not needed to understand the material. ABOUT THIS PUBLICATION After this introduction and a “Quick Start” guide, there are two main sections; one cov- ering gear for the VHF and UHF bands and one for HF band equipment. You’ll encounter a number of terms and abbreviations--watch for italicized words—so two glossaries are provided; one for the VHF/UHF section and one for the HF section. You’ll be comfortable with these terms by the time you’ve finished reading! We assume that you’ll be buying commercial equipment and accessories as new gear. -

Unicomdual DATAMODE • CAT CONTROL • PROGRAMMING INTERFACE
Radioarena UnicomDual DATAMODE • CAT CONTROL • PROGRAMMING INTERFACE User Manual www.radioarena.co.uk I. Rig Control and Programming Section The CAT control part of the interface is based on the FT2232C, the 3rd generation of FTDI’s popular USB UART/FIFO I.C. family. This device features two Multi-Purpose UART / FIFO controllers which can be configured individually in several different modes. It is designed specifically for CAT (Computer Aided Transceiver) system, which controls transceiver frequency, mode and other functions by computer, supporting Icom (CI-V), Kenwood (IF-232C) and Yaesu (FIF-232C) transceivers. It may also be used to program and clone various hand-held, mobile and base radios. The UnicomDual communicates directly with a PC through the now popular and standard USB interface. It emulates 2 (two) Serial Ports communicating with a radio at TTL voltage levels. A Serial Port connection is not needed since the Radioarena UnicomDual emulates one for you. The Radioarena UnicomDual is compatible with all versions of Windows® that support USB operation. This only includes Windows® 98SE, ME, W2K, XP or higher. Many up to date notebook computers support only USB interfaces, but no more Serial Ports. On a desktop PC the few serial devices are already in use. You can connect as many USB devices as you want to your PC. The Radioarena UnicomDual is a new CAT/Programming/Datamode interface for USB 2.0 or USB 1.1, for all those PCs without Serial Ports. Two virtual Serial Ports are created, so that any Windows™ based rig control software that is compatible with your computer and radio may be used. -
