Chuck,
The RWTST (12 volt) and WTST (9 volt) winding is for T501.? You do not need to use that method for the low-band (80-20) version of the QMX.? I would not rewind unless you have issues with transmitting and suspect the transformer has a short or was wound incorrectly.? The twisted winding is recommended (needed?) for the high-band (20-10 meter) version.? The improvements due to the winding method are most noticeable on the high-band versions, as explained in the document.? ?AFAIK there has not been a high band QMX yet offered.
Here is the link to the document:
