I do find it interesting that CBs have not become more popular on SxS. I use VHF/UHF like most others. It seems like I remember that CB transmissions during logging operations was the go to communication. I thought it penetrated the trees and cover more, I could be wrong. I might do some research on that. Maybe I am crazy.
I do know that VHF (MURS frequencies) travels better than UHF (GMRS frequencies) in the woods with the same power setting. I have tested this many times and always make sure the attenna is tuned perfect for each before the test. MURS legally requires a lower power output, but these test were conducted using the same power setting. While deer hunting, I can talk to my father at home on MURS and he can not hear me at all on GMRS. I always thought this was why folks liked to use the business bands on VHF for car to car communication.
