This Frequency Generator is based on the well known Si5351A  programmable frequency clock generator,contrary to all fareast modules with simple crystals ,it uses a very stable TCXO module made by ECS(USA) with a frequency tolerance of± 2.5 ppm.The result is a very stable carrier and much less spurious. Can be used as a Signal Generator or a control unit for HF/VHF communications receivers,tranceivers,exciters. A brief opeation manual,schematic and detailed electronic diagram included.
