Make contact with someone and have them call 911 with your information. We don’t monitor the backcountry frequencies – that would require a lot of resources.
We would expect if you had FRS/GMRS that you would leave a list of channels and sub-tones with the person that will report you missing (along with your itinerary, equipment list, boot type, wilderness experience, etc…).

However, I usually use a corded speaker/mic so I can put the radio in a pocket on my pack. With the speaker/mic the total weight is 10.5 ounces. In remote areas you can usually reach a repeater when you can not reach a cell tower. A fellow amateur and I used to help lead scout campouts to places like Anza Borrego. We would ask the other adults to check if anyone had cell phone coverage. Usually nobody did. We would then autopatch through our club repeater on top of Santiago Peak and call our wives. And, there is no longer a Morse code requirement for the General license.

About all I can say about repeater coverage is that it is different than cell phone coverage. In some areas, like Borrego, repeaters are accessible ALMOST anywhere. In the canyons of the John Muir Trail, not much coverage for anything, but with some surprises. (I document a few of these at http://www.qsl.net/aa6j/pct.)
HF gear often weighs more, but can weigh less with the low-power rigs. HF requires a much longer antenna, usually made of wire strung between trees, etc. It's not common in the backcountry except by hobbiests, although I once made a phone call for a guy who was two days into the Emigrant Wilderness. He had a tiny homemade Morse code rig.
The autopatches to the phone system are cool, but almost exclusively require membership in that particular repeater system. Still, you can usually get a local to make a call when needed.
Morse code is no longer required for any ham license. The test itself is 35 multiple choice questions from a pool of about 500 questions that are published in books. My daughter got her license at 11, so it's not real technical.
