More than 300 hams helped field-test the still experimental DXpedition mode of the FT8 digital mode in early March. The ARRL Letter reports that co-developer Joe Taylor, K1JT, said 330 unique call signs were logged during the 4-hour test. 

The DXpedition mode allows an FT8 contact to be made with a single exchange of transmissions with the DX station able to transmit up to five signals simultaneously, making it possible under ideal circumstances to make as many as 500 contacts per hour.
