Getting Started
HAM radios can be used for communication during a complete grid down.
The handheld BaoFeng UV-5R is a popular entry level radio, and a great addition to a bug-out bag. Many accessories are available, like earpiece, extra batteries, replacement antenna, etc. A programming cable allows for entry of multiple different programmed frequencies, from a computer running the free CHIRP software.
NOAA is the National Oceanic and Atmospheric Administration, a government operated administration that sends out broadcasts every five minutes 24/7 relating to hurricane, storm, solar flare, nuke, and other emergency information.
FEMA is the Federal Emergency Management Association. They are one of the frontline government agencies to respond to any large scale disaster with medical care, triage, shelter, food, and other forms of humanitarian aid.

Radios
- BaoFeng UV-5R
- Popular 2-way entry level HAM radio
- Throwable Antenna for BaoFeng
- Other UV-5R Accessories
- Extra batteries, chargers, programming cables, whip antennas, earpieces, etc.
- CHIRP Software
- Programming software to download or upload frequencies on the radio. Requires programming cable.
Scanners
Scanners are used to listen to radio feeds like police, fire, EMS. The hardware does not typically enable transmitting. Many police radio communications are now encrypted, and require specialized hardware to decrypt.
Scanner radios typically allow for scanning through a number of different channels (frequencies) until activity is detected. Groups of channels can be stored in banks, and the scanner can continuously scan 1 or more banks.
Trunking is the term for utilizing multiple frequencies to communicate with other parties.
Antennas
