If I understand, you seem to consider PTT to be Phoot To Talk.  PTT line is 
used by computer to switch system from receive to transmit and vice versa. With 
bunch of equipment like amplifiers and switching systems for radios and 
antennas, precise control of PTT signal timing allows to fine tune the system, 
eliminate hot switching, millions of unnecessary cyclings and unnecessary delays 
as experienced with semi-BK. We do not use PTT for foot switch type control by 
real feet.
