The TVStudy Version 
2.2.3 software installation package, the TVStudy 2.2.3 Installation and Upgrade Guide, and the post-
auction template XML file (TVStudy 2.2.3 Template) are all available on the TVStudy website at 
http://www.fcc.gov/oet/tvstudy.  As with prior updates, the full list of changes since the release of 
TVStudy Version 2.2.2 is included in the “Differences Between 2.2.3 and 2.2.2” section of the Change 
Log in the TVStudy 2.2.3 Installation and Upgrade Guide.
This release improves the performance of TV Interference Check mode.  It also enables 
appropriate consideration of channel sharing applications and handling of the Longley-Rice error flag
when studying DTS stations.  Finally, TVStudy 2.2.3 contains a handful of new features, including a 
widely-requested ability to evaluate more than one User record within a given TV Interference Check 
study.
For further information regarding the TVStudy software and to submit bug reports, contact Mark 
Colombo at (202) 418-7611 or Mark.Colombo@fcc.gov.
