   The clear box is a new device which has just been invented that  
can be used throughout Canada and rural United States. The clear  
box works on "PostPay" payphones (fortress fones). Those are the  
payphones that dont require payment until after the connection is  
established. You pick up the fone, get a dial tone, dial your  
number, and then insert your money after the person answers.  If  
you dont deposit the money then you can not speak to the person on  
the other end- because your mouth peice is cut off, b ut, not the  
ear piece.  (obviously these phones are nice for free calls to  
weather or time or other such recordings).  
       All you must do is to go to your nearby Radio Shack, or  
electronics store, and get a four-transistor amplifier and a  
telephone suction cup induction pick-up. The induction pick-up  
would be hooked up as it normally would to record a conversation,  
except that it would be plugged into the output of the amplifier  
and a microphone would be hooked to the input. So when the party  
that is being called answers, the caller could speak through the  
little microphone instead. His voice then goes through the  
amplifier and out the induction coil, and into the back of the  
reciever where it would then be broadcast through the phone lines  
and the other party would be able to hear the caller. The Clear Box 

thus 'clears up' the problem of not being heard. Luckily, the  
line will not be cut-off after a certain amount of time because it  
will wait forever for the coins to be put in.  
      The biggest advantage for all of us about this new clear box  
is the fact that this type of payphone will most likely become very 

common. Due to a few things: 1st, it is a cheap way of getting the  
DTF,dial-tone-first service, 2nd, it doesnt require any special  
equipment, (for the phone company) This payphone will work on any  
phone line. Ususally a payphone line is different, but this is a  
regular phone line and it is set up so the phone does all the  
charging, not the company.
