[amsat-bb] Re: Using a Yaesu FT-847 with Satellites

[Alan P. Biddle]

The most important thing about buying a used FT-847 is to make certain is
has the bi-directional CAT CPU.  The first ones produced did not, which
makes them nearly useless with tracking software.  Years ago Yaesu did
updates free of charge, but there are a few around which have the original
chip.  It isn't something you can fix at home.
