More on Ham Radio in Emergencies

From Bob Conder, K4RLC:

The November issue of the Southeastern Repeater Journal has articles by
three hams who were in the Mississippi-Louisiana gulf area post Katrina,
either conducting communications or working with the Red Cross Disaster
Services. It speaks to what it was like and what worked for communications.

... get a copy of the entire issue if you can.

Basically, LCD radio services were what worked - lowest common denominator
- VHF and HF phone simplex. Battery operated, off the grid.
