I believe the 897 has a similar issue. Someone wrote a QST article many
years ago about tapping into the front panel mic connector to get CAT when
the back connector is set for use by the tuner, but I cannot find it
anymore. Instead of implementing that idea I just used an external LDG tuner
that did not need to be controlled by the radio.

I had pulled that article from the QST archives, so try searching there or
ask on the 897 Yahoo group, and there may be an 847 group too.

The operating manual states that a user can do C.A.T. with the radio, which
he loves & is successfully doing, but cannot utilize the built-in antenna
tuner at the same time!

Is anyone familiar with a hardware modification or software modification
which will permit him to utilize both of these great features at the same
