My experience with line of sight radios, both for volunteer SAR and work (NPS) is that they are very quirky and not totally dependable. Battery life is also an issue, though that may be better now. Do you have some sort of base station that monitors traffic 24/7 or at least at stated times. Doesn't do any good to broadcast if there is no one listening...

But when they work, they are fantastic!!
