Using LimeSDR mini as a RF source

In one of the previous posts we saw how we could transmit DATV using LimeSDR mini. This time we are going to use our LimeSDR mini as a RF source in our home lab. The whole setup is based on GNU Radio and the QT

Transmitting DATV over the air with LimeSDR-Mini

Transmitting voice is something every ham operator must be doing regularly. There is a breed of hams which only stick to digital modes, while some prefer morse. Some ham operators go above and beyond to transmit real-time video stream over the air. Back in the
