FT747GX to MMT 50/28
                     ====================

This mod describes how to interface the FT747GX transceiver to the Microwave
Modules MMT 50/28 6 metre transverter.
The transverter requires just a few milliwatts of drive on 28MHz, and this
is how to obtain it.

1.  Fit a BNC socket and a SPST switch to the FT747GX's back panel.
2.  There is a coaxial lead from Q32 (located behind Ext. ALC socket). Cut
    the coax and connect both sets of the cut ends to the BNC socket. This
    provides the low power drive to the transverter.
3.  Locate the wire from J06, cut it and wire it to the SPST switch. When the
    switch open-circuits this wire, the FT747's PA is disabled.

The transverter should work on a drive level between 0.1 and 750 milliwatts.
The above mod. provides approximately 0.8 milliwatts, which has been adequate
to drive the transverter to its full 20 watt output in all modes.

To restore operation of the FT747 for HF use, disconnect the transverter and
set the SPST switch to its closed position, thus re-enabling the 747's PA.

Note:  The transverter MUST be disconnected when using the FT747 for full
       power HF.
