The Doug Hall voter works on noise just above the voice band, just over 3 kc in freq. If the response from the remote sites is different and either boost or attenuate this band of signal, the voter may false. Also, if the audio response if different between voters, the repeated signal will go up and down and change fidelity as it changes receivers.
The DHE and GE voters are dynamic and will change receivers during a transmission if the user takes a fade. Some of the MOT Spectratac jobs voted on initial receiver un squeched and sent a quality tone down the line for the voter, and it would remain on the same receiver during the transmission.
