Trigger 28 (Interplanetary Cruise with Direction-Finding)                     
                                                                              
     This mode is designed to provide a low bit-rate Survey with low temporal 
and spectral resolution for periods during cruise. No Wideband or Waveform    
measurements are made. The entire RPWS frequency range (1 Hz - 16 MHz) is     
covered.

The HFR is in direction-finding mode for the frequency range from 3.6 KHz to  
319 KHz.  Thus, measurements are made on all three monopoles EU, EV and EW    
for Bands ABC, but for Band H1 only on the dipole EX and the EW monopole, and 
for Band H2, only on the dipole EX.

Bands ABC require 6.34 sec to complete, H1 requires 3.52 sec, and H2 requires 
4.68 sec for a total of 14.54 sec per sweep. However, to keep the bit rate    
down the HFR only performs one complete sweep every 64 seconds.
