They did. I would have to do some digging to uncover the details, but 
IIRC, a submultiple of one transmitter's oscillator was fed via phone 
loop to the other site, where it was multiplied back up. Also, IIRC, 
the program audio at the originating end was delayed before being fed 
to that transmitter so that the modulation at both ends would match in phase.
