On Monday, October 20, the ARRL filed a Petition for Modification or Cancellation of Experimental Authorization (Petition) with the FCC with respect to WE2XRH., an experimental license issued to Digital Aurora Radio Technologies (DART), permitting operation in the 7.1-7.6 MHz (40m amateur) band using a 20 kHz bandwidth digital emission at a transmitter
output power of 100 kW and an ERP of 660 kW within a radius of 1500 kilometers of Delta Junction, Alaska.

According to the ARRL, "Simply stated, there is a 100 percent certainty of severe, continuous, harmful interference from operation of the DART facilities as authorized by the Commission to ongoing Amateur Radio operation at 7.1 to 7.3 MHz." If you would like to help preserve "perhaps the most heavily-utilized Amateur HF band in the United States", and prevent it from being effectively taken away from hams around the world, you may contact the FCC by email, mail, or telephone. For more information, see the full ARRL article, and we will provide more information here as it becomes available.
