DIY SDR HF Transceiver v1.4 with STM32F103C8T6 without Linear Amplifierwith the addition of a transverter can transmit at a frequency of 144mhzusing software Powersdr v28.0.187 Windows 10 64bitLO using Si5351A which is controlled by STM32F103C8T6 produces a frequency that is wide enough Max 160Mhz, of course allows us to make Exciter up to 10M band. LO = work freq x 4.My BPF takes from the us5ncj design using an already-built Inductor, so it is practical without the need to roll.https://www.ye3cif.com/diy-sdr-hf-transceiver/
