CAT FT-857D from a web browser Technical aspects

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.

FT-1000 Mark V Remote Station with a Raspberry Pi

There are currently proven solutions using a Raspberry Pi to operate a remote radio station whether industrial or open source; those include MFJ’s RIGPI solution or RemoteQTH’s Open Source developments.

Owning a Raspberry Pi 3B with a sound card, I wanted to make a remote control prototype of my FT-1000 Mark V Field that does not require any developments and uses only open source software, free or low cost softwares. I call it a prototype because an operational solution must take into account the remote radio ON/OFF, the reset of the Raspberry Pi, computer security (anti-intrusion, …) and possible remote switches of devices (amp, antennas, …)

I already used my Raspberry Pi to run WSJT-X in FT8 remotely controlled by my PC using VNC Viewer. So I looked for a software solution to transmit the sound between the radio and the PC and a simple and user-friendly solution to control the radio:
– for the sound I chose the Mumble suite that has the shortest latency, the other solutions leading to latency of more than a second,
– for the the radio control I chose flrig that supports 60 different radios and that has a user-friendly interface (GRIG and rigctl were also tested).

The solution described was successfully used to make phone QSOs with the Yaesu FT-1000 Mark V Field on a WiFi LAN. It also works with a Yaesu FT-857D.

I also tested a second solution that uses the usual software suites on the PC (DXLab, HAMRadio Deluxe, N1MM) to control the radio using COM TCP ports. It will be described in another presentation.

This page contains a video presentation of the first solution and a file providing all the commands to install the softwares.

FT-857D CAT from a web browser
Functional aspects

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.

YAESU FT-857D parameters display on a TTGO-T-Display

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.

IC-7300 : CAT and data configuration

The implementation of data transmission with a radio is sometimes tricky because it involves physical links (serial, USB, sound), a CAT link (Computer Aided Transceiver) and configurations of the transceiver and of the computer (PC, Raspberry Pi, …).
This article presents the configuration of an IC-7300 with an SB2000 but also with a direct USB link to interface the softwares N1MM+ and WJTX.

Have a good reading: CAT interface and IC-7300 data.

YAESU FT-857D parameters display with an Arduino

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.
