What did amateur radio operators do during the 9/11 attacks? #ARRL #hamradio

On a number of fronts, amateur radio operators did what they could to communicate on 9-11.

Emergency relief efforts in both Lower Manhattan and at the Pentagon were augmented by volunteer amateur radio operators in the weeks after the attacks.^[3]

Please recall that cellular systems in New York City and Washington DC areas were overloaded.  Land Mobile Radio systems were congested, if available at all.

In rural areas, amateur radio Skywarn, Radio Amateur Civil Emergency Services, and Amateur Radio Emergency Service operators monitored High Frequency and local systems.
