In case there's any interest, the hurricane/flooding rescue effort in Texas is using Zello channels for dedicated communications among rescue teams. I've been listening to the Harvey Small Animal Rescue channel. There's as well a Harvey Animal Rescue channel for larger animals. There are a multitude of other Harvey-related rescue and reporting channels on the Zello system as well. Each channel has an acting dispatch person and many volunteers in the field pursuing the rescues. It's interesting to hear.
