New: @FBINewYork report says "pre-operational planning" went in to Jan. 6 #CapitolRiot. Some "used amateur #hamradios & encrypted app, such as @signalapp, to communicate operational plans.”

“These individuals believed these communication methods were more secure than a cellular phone line. (Attackers) used call signs as opposed to their true names on these radios..."

"...The (attackers) programmed the frequencies of their radios prior to traveling to the Washington D.C. area. Accessories used with the amateur #hamradio included ear pieces, throat mic[rophone]s, and push-to-talk wrist buttons..."

"...(attackers) changed from their regular #COVID19 masks to a mask that covered their neck and ears. The (attackers) used these masks to conceal their earpieces and throat microphones..."

"...A (terrorist) used checked luggage to transport operational equipment including helmets, knives, and trauma kits. (Attackers) discussed having a change of clothes and a handcuff key on them to evade law enforcement.” #CapitolHill #Jan6
