The SDRuno software allows to interface the CAT link of a transceiver using the Omni-Rig software to control the frequency and mode in both directions. This software also provides frequency and mode synchronization with another CAT software such as DXLab Commander for example, using virtual COM ports by emulating a Kenwood CAT. This article presents such a configuration with the FTdx101 and another configuration without the Kenwood interface whose advantages will be presented.Continue reading “FTdx101 CAT with DXLab Commander and SDRuno”
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.

CW Skimmer is a software that allows to:
– decode simultaneously on a frequency range:
– either the stations calls,
– or the transmission content.
– display the Morse code (dots/dashes) of a signal.
– generate spots to a local or remote server.
– feed a spectrum window of the frequency range for example the Spectrum window of N1MM.
In input CW Skimmer uses either a 3 KHz audio stream or an IQ stream from an SDR up to 192kHz of bandwidth. It is in the latter case that the use is most interesting. In our case both interfaces were tested interfacing the SDRuno software.
There is also a server version of Skimmer without MMI that can simultaneously decode the calls on 7 amateur bands (if the associated SDR allows that) and provide the corresponding spots.
The attached presentation describes the configurations used for the tests I performed as well as a findings on the use of that software.
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.Continue reading “YAESU FT-857D parameters display on a TTGO-T-Display”
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.
The Yaesu FT-1000 Mark V Field does not have an “Intermediate Frequency” output that allows to view a “waterfall” or spectrum view of the selected band using an external device.
This article, after presenting different solutions, describes the solution chosen and its implementation with an SDRPlay RSP2PRO receiver and SDRUno software.Continue reading “FT-1000 Mark V Field panoramic adapter output”
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.Continue reading “YAESU FT-857D CAT interface box”
