In this video I go through the theory of HF radio wave propagation. In part 2 of this video I’ll do a practicle demonstation of shortwave radio reception through various radios and antennas / antenna tuner. Concepts covered n this HAM radio tutorial: * Ground wave propagation * Sky wave propagation * Ionosphere layers D, E, F * Radio wave skip and hop zones * Pedersen Ray * EME Earth Moon Earth radio communications * Long path and short path radio waves Equipment used / mentioned in this video series: * K-Po WR2100 PLL Synthesized World Band Receiver. * Tecsun (Kaito) PL-389MP Short Wave radio * Yaesu FT-897 HF/VHF All Mode Transceiver * Yaesu FT-950 HF / 50MHz band All Mode Transceiver * Yaesu VX-6 Submersible Dual-Band FM Transceiver * Yaesu FT-817ND solar powered portable go-pack * Yaesu FRG-7000 Receiver * RigExpert AA-200 Antenna analyzer * Simple wire antenna * Par electronics Par End-Fedz EF-10-20-40 full length half wave dipole * Buddipole™- hf/vhf portable dipole antenna system * MFJ Deluxe Travel Antenna Tuner – MFJ-904H * Amateur Extra HAM radio license – KD8LON
