Some one most likely will be running this same radio, or know how to do the privacy channels for setup. I'm kind off surprised they will need that unless there is a lot of traffic on the ' Comms', outside of your group.
Let us know how it goes with range, clarity, and the terrain encountered. I always like hearing...REAL TIME....review use. I also have not looked into the privacy channel aspects of the MXT275 yet either. I was going to change the power plug cord out and into a permanently wired system, but I am now considering keeping it like it came, thus making it more portable.
I can't remember if you upgraded your antenna, or were planning to run the factory shorty. If you upgraded, which style, and do you plan any informal
RANGE TESTS between them while out. I plan to keep the OEM, as a backup and spare, in case of damage to the Midland 6 dB I bought, while out on the trails.
