Because (Someone correct me if I'm wrong) on the FT-1000MP and the
FT-920, which is what the MD100A8X is designed to work with, pin 2 is
for +5 volts. On the FT-1000D, FT-990, FT-890, FT-840, etc., pin 2 is
a ground.
Also, just the opposite has to be done to use a MD-1 on a 1000MP or
920.
Pin 2 must be opened on the MD-1 and regrounded elsewhere.
