a firmware upgrade available from Yaesu to resolve the issue.
Wayne replies:  This is true, but The Station Program doesn't
read the frequency from the FT-847.  It only writes frequencies
to the FT-847, so it should work fine with early FT-847
firmware.  The Yaesu Doppler tuning algorithm in The Station
Program was written for the FT-736 which doesn't have "read
frequency" capability in its CAT interface.  The source code for
The Station Program was lost before the FT-847 came on the
market, so VP9MU was not able to add "read frequency" capability
to his Yaesu tuning algorithm.  I once had a serial problem with
my FT-847 when I used a home-made serial cable that only
connected the 3 wires specified in t
