The control of a radio station is usually done by an application installed on a target machine, this application being often developed specifically for an operating system (Windows, Unix, …). After a description of the functional aspects in a previous article, this video presents the technical aspects of the implementation of the FT-857D CAT in a web browser.

A hamradio station remote control is usually done by an application installed on a dedicated machine, this application being often developed according to an operating system (Windows, Unix, …). This video shows a FT-857D remote control using an application developed on a web browser and therefore independent of the system. The web server is an ESP32 TTGO micro-controller board connected to the FT-857D.
The developments are based on those described in the article on FT-857D parameters display on an ESP32 board.
The video presents the developments functional aspects.
The video is in French but is subtitled in English.
The work was to port the FT-857D CAT library and the corresponding display application on the ESP32 T-Display. This software was originally developed on an Arduino Nano (see article) The goal was to have a platform of the same size as the Arduino Nano but with in addition to the serial link, an on-board WiFi and Bluetooth.

This interface box allows to connect through the YAESU FT-857D’s CAT (Computer Aided Transceiver) mini-din 8, both a serial wired link to a computer and a PTT line to an amplifier. It also includes a Bluetooth module to replace the serial wired link if necessary.

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.
