Last Sunday I went with my father (EA1AQ) to activate Pico da Fiosa (EA1/LU-009) and this is the vide we made. It was a very nice place with an improvised table, great views and excellent conditions for SOTA operation (low noise).
I was running 20W with my FT-857 manpack, an SG-211 tuner and a military whip. The battery is Lithium Polymer and works great. It is powerful and light. I am very satisfied with its performance.
