HAM is still a very necessary tool for keeping in contact in the mountains and such. When I was younger I did some SCCA rally events. Those events would be impossible without the volunteer HAM operators that show up and set up temporary relays on a couple of the biggest foothills in the race area. Cell coverage is just too spotty, and satcom stuff is just too expensive. My understanding is that search and rescue uses the same approach for the same reasons.

> HAM is still a very necessary tool for keeping in contact in the mountains and such. Depends on the location. The company I work for produces a mountain-top repeater[0] series. Hundreds of them are distributed throughout the Rocky Mountains in British Columbia, providing an expansive coverage for handheld devices. If you're curious about what an installation site looks like atop a mountain, check out pages 38-39 in an older product guide[1].
