Trigger 74 (HF-WBR Interference Test)                                         
                                                                              
These triggers cycle through 4 frequency steps in HF-WBR mode, in order to    
investigate the interference line seen at 125 KHz.  The trigger set-up is     
similar to Trigger 36, with an initial HF-WBR frequency of 125 KHz. Then      
each step of the sequence changes the frequency and dwells for a minute.      
Finally Trigger 28 is invoked.
