Response to brushing up on ham radio and morse code. Ok, assume you have done it. Let us also assume that you have a generator and a lot of fuel - or if you would like, a tall antenna, an expensive handheld and plenty of batteries. Based upon my life experience, my work as a volunteer radio operator for the county, and having an understanding of the county resources, I say the following and this relates to my county: 1. you will not be allowed to use any county repeater for any personal usage or to provide reports unless specifically instructed to do so; 2. there are no warehouses of blankets or food. 3. the police will not respond to calls for assistance - the utilization will be directed (how about holding down the sheriff substation in the last riot with an old lady radio operator and a boy scout and being told to lock the door to the substation and not respond to calls for assistance). 4. it is highly unlikely that the fire department will respond to individual radio calls for assistance (having done that in reporting fire locations during an extensive riot). I am not negative, just suggesting that you consider other preps. It is January 2019. Today, I am baking more hardtack. It takes hours to bake at a low temperature. The fuel used will also heat the house. The time and money spent will be a better use (for me at least) than reviewing morse code. I will also be throwing out old tax returns, consolidating supplies so I remove fire hazards and gain a current understanding of what I have put aside - another use of time.
