Operation with FT-990 ROM 1.2, FT-1000 V5,
FT-747 and FRG-100
This section is about the early firmware versions of FT-990 and FT-1000, the FT-747 or the
FRG-100.
The early firmware versions of FT-990 (ROM 1.2) and FT-1000 (V5), the FT-747 and the
FRG-100 do not provide a real time transmission of data such as frequency, mode… You have
to select FT-990 ROM 1.2 or FT-1000 V5 in the Setup dialog box to run TRX-Manager (or
should this happen FRG-100 FT-747).
update function
TRX-Manager was implemented to run with these transceivers with following differences :

The real time monitoring doesn't run : you have to press the Update button to
manually update the monitoring display ; but the program does it automatically when
calling specific functions such as : memory reading, QSX, memory or QM writing and
parameters setting.

It is possible to have a slight difference (10 to 20 Hz) with the displayed frequency and
the right frequency ; you have to press Update to accord them,

The automatic band scope refreshing is not working.
However, when controlling the transceiver from the PC you should not see a great difference.
In fact the program simulates a communication with the transceiver through a virtual com
buffer.
Note that for the FT-1000 owners, a version 6.0 ROM chip is available from Yaesu USA and is
very easy to install (just a thought).
