# The first commit's message is: Updated RDS transmitter: flags, PI and date/time Merging baseband audio tone generators Merging DTMF baseband with "tones" baseband Added stealth transmit mode App flash section bumped to 512k RX and TX LEDs are now used Play dead should work again, added login option Morse frame gen. for letters and fox hunt codes Merged EPAR with Xylos Made EPAR use encoders for frame gen. Moved OOK encoders data in encoders.hpp Simplified about screen, ui_about_demo.* files are still there BHT city DB, keywords removed BHT cities DB, keywords removed Update README.md RDS radiotext and time group generators # This is the 2nd commit message: Update README.md
