Over on YouTube Corrosive from the SignalsEverywhere YouTube channel has uploaded a video showing us how to use SDR-Console V3 and a PlutoSDR to transmit ham radio voice. In the video he sets his PlutoSDR to transmit from his microphone at 445.5 MHz, and to receive at 434 MHz. He is then able to talk to a friend using a handheld who is receiving at 445.5 MHz and transmitting at 434 MHz.
