I carry a Garmin Rino 130. Like Jerry said, Game and Fish monitor the frequencies, they use scanners. Motorola use to make a 5watt that would do pretty even if it was heavy. I talked from the top of Pole Mt to Lost Trail Campground to let my wife and son know I was surving the storm without a tent.
When my brother and I hunt together we use code just because, ie. bring backpacks to 1/2 mile above sat's #2. How does that hurt anything? I also carry a whistle and gen 3 night vision.
