A TTGO T-Display demo app is available on Github/LilyGO.
This application:
– displays an image and then a timed sequence of screens of different colors (red, blue, green),
– displays the power voltage on short-pressed GPIO 35 button,
– puts the ESP32 to sleep on the GPIO 35 button long press,
– launches a WiFi scan on short press of the GPIO 0 button and displays the result.
This article provides references on the ESP32 and on the LilyGO TTGO T-Display development board used in my projects.

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.

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”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.
