Trigger 80 (Direction-Finding Survey)                                         
                                                                              
     This mode is designed to provide a Survey with fast temporal resolution  
and standard spectral resolution for cruise periods following Earth Swing-by. 
Periodic Waveform measurements are made.                                      
The entire RPWS frequency range (1 Hz - 16 MHz) is covered.

The HFR is in direction-finding mode for its entire frequency                 
range from 3.6 KHz to 16 MHz. Thus, measurements are made on all three        
monopoles EU, EV and EW.

Bands ABC require 1.69 sec to complete, H1 requires 3.84 sec, and H2 requires 
3.07 sec for a total of 8.60 sec per sweep. However, to allow time for LFR    
and MFR snapshots to occur without interference, and also to limit the        
bitrate, one complete sweep is done every 32 seconds. To avoid the            
interference from the DF mode, the MFR uses the EW antenna.
