I use TRX Manager which I was advised to use by Vic N5YY. It was the only logging program I could find which specifically stated it was compatible with the FT-1200. It works well for my current needs and cost about $80 dollars or so as a one time only cost. It has the MMVARI digital program imbedded in the tools. I tried to add other more popular digital programs but could not get them to work probably my own fault due to configuration difficulties. I don't use digital modes currently, exclusively phone for now.
God bless the computer junkies, they shall inherit the earth.
