The list is appears to be a random mix of AM/FM radios (receiver only), walkie talkies for different frequency bands, etc. Without any context, this list is not helpful at all - or outright confusing.

It's also noteworthy that different countries have different allowed frequency bands and usage restrictions.

I suppose those who have an interest in emergency communication may want to have a look at what their national amateur radio society has to offer.
