The article describes optimal mechanisms of wideband transmitter and receiver (150-600 kHz) for information transfer and for researching of thin structure of ionosphere in different helio-geophysical conditions. The proposed schemes give an opportunity to receiving with division of beams and to use the energy of all waves for increasing interference immunity.
