Operation with FT-980
This section is only for use with the FT-980
Limitations
The FT-980 was one of the early transceivers featured with a CAT Control system. So there
are some differences between the FT-980 and with later models of Yaesu CAT transceivers :

no dual control : you have to choose between CAT Control or Manual Control,

no S-Meter (Band scope is not available)

no dual VFO system : the split mode uses a memory channel

two VFO's for GENeral coverage or HAM coverage

tuner functions and status are not controllable via the CAT system.
Note : you may have to disconnect the PIN 4 of the DB9 plug (FT-980) to prevent the RIG
from keying during CAT Control.
CAT Control Mode
To be under CAT control you have to press the CAT button (main toolbar's button) or the F9
key. When the transceiver is under CAT Control you may not change anything from the
transceiver (as frequencies, mode…). You have to press CAT or F9 again to leave the CAT
control mode.
When you run TRX-Manager for the first time after the XCVR was OFF, you may have to press
one or more times the CAT button before the CAT Control starts, or wait a few seconds. The
CAT control is only effective when the CAT button looks as if is depressed.
Memory channels
Through the CAT system, the FT-980 is provided with 16 memory channels (not 12) ;
However when the software is reading the memory channels content for the first time (after
the FT-980 was OFF), the reading is false. You must change the memory content through the
software to reestablish a correct reading.
Split and QSX
The split modeuses a memory channel. During the split operation TRX-Manager uses the
current memory to store the TX frequency (this frequency may be recalled from the QMB ).
IF Shift IF Width
One interesting feature of the FT-980 is that IF shift and IF width may be controlled from
the PC. You have to drag the two corresponding sliders (monitoring) and move them to
change the shift or the width. The w and s buttons centers the settings. A graphic readout is
provided to see the current bandwidth and IF shift.
