FT767

       I have had my Yaesu FT-767 modified by the service facility for three
things:
       1.  Memory battery circuitry.  Previously the circuitry caused
       unnecessary drain on the memory battery, resulting in shortened
       battery life.  There is a kit available for this modification,
       which I ordered (free of charge).  After reading the instructions
       and not being able to even find the components involved, I took
       the unit down to LA to the service facility.

       2.  Hum mod.  I don't know anything about this mod.  It was
       performed while the unit was in for the previous mod.

       3.  DATA IN/OUT Jack audio control modification.  This mod was
       originated by me.  Since I have had the unit, I had not used it
       for packet because I could not defeat the audio from the speaker
       in any way without rendering the audio from the DATA IN/OUT jack
       unusable.  This jack was supposed to provide direct connection to
       the FM modulator and discriminator for packet.  It obviously was
       affected by the AF gain, external speaker disconnect, i.e., anything
       which affected the audio at the built-in speaker.  Examination of
       the circuit diagram seemed to indicate the audio for this jack
       came from the headphone circuit.
