I have added a few Yosemite National Park channels to my Stanislaus National Forest Feed (located under Calaveras and Toulumne County listings). I am able to receive Mt Hoffman (172.65) repeater quite well which transmits the Toulumne Meadows Ranger District and Tioga Pass operations. I"m also monitoring YNP Fire, 172.775. I cannot receive any valley floor traffic, but nice to listen to activity in the backcountry.
