# HG changeset patch # User Tom Hayward tom@tomh.us # Date 1409267688 25200 # Thu Aug 28 16:14:48 2014 -0700 # Node ID 78b698f3408ea49bac73e130a7638e48b7d1c640 # Parent d5a4ed31fa2afd5820516b8d02ed28565c960bdc [th9800] Add driver to read and write .dat files for TYT-TH9800. #1353

This patch adds support for reading and writing .dat files compatible with the TYT TH-9800 manufactuer's software. I don't have a TH-9800 available to work on the upload/download portion of this driver, but this should provide a head start for anyone who wants to work on that. (I suspect the contents of these .dat files will be equivalent to Chirp .img files for the same radio.)
