#  Chirp Driver for TYT TH-9000D  Radio (2 meter, 1.25 and 70cm radios)

#  by David Fannin <dfannin@sushisoft.com>, KK6DF

#

#  Version 0.5 (Experimental - Known Bugs and Issues)

#  Use for development purposes only!  

#  Features working:

#         - single class file for 3 radio types - 144, 220 and 440 mhz models)

#         - Download from Radio

#         - Display Memories (only None, Tone, TSQL signalling supported)

#         - Save image file

#         - memory map decoded (about 90%)

#         - Upload to radio

#         - Modification of memories

#         - feature settings

#         - added Startup ID label

#

#  Features not working:

#         - DCS , Cross Signaling

#         - Skip channels

#

# Global Parameters
