Here is what I want you to do tonight.
Brew yourself a a couple cups of coffee the old-fashioned way. Don't screw around with the damn K-Cups. Grind some beans, toss them in the percolator with some well water, and put it on the stove. If caffeine keeps you up, use decaf. Kick back,enjoy the sunset and a cup of coffee with your significant other. Bonus points if you use a camp stove or fire.
Congratulations. Welcome to the human race.
Now turn off your Internet, go to your radio room/corner, and turn on all your receivers. The scanner should be listening to the local public safety traffic, and your shortwave set should have something interesting on.
Using your multimeter, measure the total current draw from your power supply to your receiving equipment.
That's how many amps your setup is drawing.
Now divide the total Amp Hour rating of your emergency power setup (I bet most of you have a deep cycle battery) by two.
Divide that number by the number of Amps your equipment is drawing. That's how many hours you can listen on your current emergency power setup.
Are you happy with that amount of time? If not, then you need to work on your emergency power capability.
Now keep your Internet disconnected for the rest of the night, and listen to the airwaves a while.
Repeat the coffee and sunset thing as often as you like. Use remaining after sunset time to work on your radio room/corner.
