As with prior updates, the full list of changes since the release of TVStudy Version 2.2 is included in the “Differences Between 2.2.1 and 2.2” section of the Change Log of the TVStudy 2.2.1 Installation and Upgrade Guide. This release corrects a number of minor issues, both in the template and software, uncovered immediately following the release of TVStudy 2.2 and the Auction Closing and Channel Reassignment Public Notice. 2 Although minor, these issues can impact the results of studies conducted with TVStudy 2.2, and this update is strongly recommended for all users of TVStudy. Additionally, please note that this version of TVStudy does not address the issue with TVStudy 2.2 relating to LPTV stations. 3 An update addressing that issue is still expected in the coming weeks. For further information regarding the TVStudy software and to submit bug reports, contact Mark Colombo at (202) 418-7611, e-mail Mark.Colombo@fcc.gov. – FCC – 1 See Office of Engineering and Technology Announces Release of Version 2.1 of TVStudy for Processing Construction Permit Applications Filed With the Media Bureau Implementing the Results of the Repacking Process, Public Notice, 32 FCC Rcd 998 (OET 2017) (“OET will continue to make improvements and other changes to TVStudy that are necessary and appropriate, and will inform the public via public notice when new versions of TVStudy are released.
