I am in Northern Maine, where the logging trucks all use the MURS frequencies. Each road maintained by the Maine North Woods has signage which directs you which MURS channel to use. "4 wheelers" or road users such as myself are required to announce their location as a matter of safety. I was seeking a good quality MURS handheld for this purpose; I've ordered the Ritron PT 150M which operates exclusively on the MURS channels. It looks like a good solid unit and I like that it is American made. I am waiting for it to arrive, does anyone have experience with this model?
