A great book on NVIS. If you are into emergency communications or are your teams comms guy you need this information.
Remember rather than making ANY contact the Guerrilla should be focused on making DIRECT contact with specific people. Learning NVIS will help. HF radio is our goto radio once we have moved beyond line of sight communications and a NVIS antenna configuration mixed with HF is what is needed to get that job done.
If you find this or any of the other information I put out useful consider supporting this site on Patreon
