GN Docket No. 12-268

On February 4, 2013, the FCC’s Office of Engineering and Technology (OET) released
Version 1.1.2 of TVStudy software for performing interference analyses using the methodology
described in Bulletin No. 69 (OET-69). At that time, OET sought comment on the software
generally, as well as the identification of any errors, unexpected behaviors, or anomalous results
produced in running the software. As a result of user feedback, OET is today releasing an
updated Version 1.1.2 of the TVStudy software. This update addresses an issue with calculation
cell indexing that can result in the population of some cells not being correctly considered, and
which may cause the program to crash in unusual instances. The update affects only the
command-line program (C code); the graphical user interface (Java code) is unchanged and its
version remains the same (Version 1.1.1). To facilitate the update process, the
2013Jan_tvstudy_files (which included both the software and all of the required databases) have
been replaced with separate files for 2013Apr_tvstudy (software only) and the databases (cdbs,
terrain, census), which are unchanged from the initial release. This means that only the TVStudy
software (less than 2 MB) needs to be downloaded and updated; the various CDBS, terrain, and
census databases need not be replaced. It is recommended that all TVStudy users apply this
update so that results will match those obtained by the FCC.
To support the requests that OET has received for improved ease of installation on Linux
platforms, a separate build (executable file and source code) for Debian-based Linux systems
(such as Ubuntu) is also being released along with instructions for configuring the software for
use on Debian/Linux platforms. All of these files are available on the FCC website at:
OET invites interested parties to provide feedback, and to meet with OET staff regarding
the installation and operation of the TVStudy software to help ensure consistent results.
Additionally, a non-FCC e-mail user group (list-serve) is open to interested parties at
