Sherman Peak has an exposed summit / activation zone. I hiked to the summit from Trail 72 along the western slope. Be prepared to hike through large boulder fields; trekking poles helped greatly. Plan to use a mast if using a wire antenna. I ended up using a trekking pole and the tallest dead tree which put my EFHW at around 6' off the ground.
I was not fortunate to get any contacts nor activate this peak today. This was mostly due to my current limitations in radio gear. I used a Yeasu FT-2D at 5 watts with a 42 inch tape measure type of antenna. Although well within the exposed activation zone, the forested summit prevented me from reaching out to the northeast where I easily picked up two contacts earlier from Mount Baldy a few hours prior. I was calling on 146.52 MHz FM voice. I had a great line of sight to five other summits in the Plains, Montana area.
