On March 16, 2001 the Federal Communications Commission granted the United States Hang Gliding and Paragliding Association (USHPA), a radio station license in the IB business radio service for an unlimited number of vehicular and portable units in specified quantities. The channels licensed for use by the USHPA are below.
There is a transmition power limit of up to 50 watts. The call sign issued to the USHGA was WPRY 420.
In order to transmit on these channels legally you must have either the (VA) or (PA) special skill signoff through USHPA or have an amateur radio license.
