Tomorrow I will activate the National Mall (DZ06) on the FO-29 pass at 1724Z tomorrow. Unfortunately I can't stay for more than the one pass, but will return several times in the future. The National Mall is about three quarters of a mile north of my apartment, so I will walk there with my normal satellite gear (2 Yaesu FT-817s and a Microset VUR-30 amplifier) and Elk antenna. Since I am carrying everything on me, not setting anything up, and have a relatively discrete location in mind, I do not anticipate any problem with the authorities, but one can never tell! Check my Twitter @PRStoetzer for real time updates.
I will be around 435.865 MHz +/- Doppler.
I will try to activate as many of the feasible NPOTA sites in the District of Columbia as possible on satellite during the rest of the year.
