A display of some Yaesu FT-857D’s parameters was developed for a 4×20 LCD screen. The software implements via the serial link the FT-857D CAT (Computer Aided Transceiver) controls and additional readings of the transceiver’s EEPROM. The developments were made from a source code developed for Arduino by VE3BUX. See my web site for more details (https://f6czv.fr) 73 Philippe F6CZV
