There'll be more posts on this over the next few days, just some early thoughts on a really fun day playing ham radio at Mt. Tamalpais. The antenna wound up fairly high at our final location near the campsite. I thought there might be issues with the high winds, but aside from being generally cold outside the tent, everything went great. Earlier in the day, with a much lower antenna we demonstrated more of what I started to see at Baylor Pass . The radio was setup in a canyon along Bootjack Trail. I surmised we'd only reach stations pretty much directly south of us, and sure enough : and in more detail the one station, K6FOD, that spotted us in our admittedly very short time transmitting was lined up along the canyon.
