You propbably have a version with the issue corrected or with a serial number starting with 8G05xxxx
Cat Control Operations
The FT-847 seems to have a set of unique op codes for CAT control. Yaesu in general, does not appear to have a consistent set of codes for
any of their radios (unlike Kenwood for example).
Given that, you can't select another radio in a software offering that doesn't show the FT-847 specifically.
The original design for the FT-847 did not include two-way CAT control operations for frequency and mode. You could use your PC to give
commands to the radio, but the radio could not report back
any frequency or mode information to the PC. Many, including QST, complained about this shortfall, and the company modified the firmware in
the radio to enable two-way CAT control operations for
frequency and mode. Starting with serial number 8G05xxxx , two-way CAT control is standard.
In a real credit to Yaesu, it offered to upgrade any earlier model radios to the two-way CAT control, so many of the earlier models have
two-way CAT control. If you're buying a used FT-847, ask if it has been upgraded.
The CAT control for the FT-847 does not convey the final digit (i.e., the ones digit) under any circumstances, so no external software can
ever resolve any frequency better than 10 Hz. The FT-847 itself resolves to 1 Hz.
