Only locally, or a bit farther with repeaters, but there aren't nearly as many GMRS repeaters as HAM repeaters. Where HAM rigs shine is for national/global communications. HAMs using HF and other parts of the spectrum can talk to each other all over the country/globe. HF requires very long antennas (the one my brother just installed at home is 133' long), so it's not portable. So, in a SHTF situation, HAMs using HF rigs will be the source of national news. For instance, if I was HF-equipped, and China started bombing us, I could contact my brother on the east coast to see how he's doing. But I'm not a HAM, don't have an HF rig, and really don't want to, so that's purely a hypothetical. I've always counted on local HAMs using HF to communicate and then locally sharing the news, but if the HAMs disappear, that's a big loss of emergency comms...
I always wanted to take it up as a hobby, but then I remember that I’ve got far too many hobbies as it is.
