Title: [D8818ADT], Letter from Thomas Alva Edison to Pennsylvania Railroad, Robert E Pettit, February 13th, 1888
Editor's Notes: "Within the past three months we have put on your telegraph lines two of my Phonoplex circuits-one between Altoona and Pittsburgh, the other between Altoona and Mifflin." TAE explains why the Phonoplex is interfering with the Morse line and asks that the Railroad allow Logue to make some modification to the Morse line so that it can work with the Phonoplex.
