Building a modular transmitter.
I obtained my ham radio licence more than twenty years ago and until recently, I had never build a radio transmitter. But all than will change. I will divide the transmitter design into seperate basic building blocks, and each block gets its own video. In no particular order: the PLL, the VCO, the modulator, the digital controller and much more.
