FLDIGI Yaesu FT991 SETUP version 3.22.7 WIN 10 COM 3 COM 4

FLDIGI SETUP MY version 3.22.7 WIN 10 COM 3 COM 4

As a couple others have got FLDIGI to work with this write up I want to point out something very interesting.

If you are having real problems please UNINSTALL the ALL COM PORTS (hidden ones too) and there is a check YES UNINSTALL DRIVERS in the uninstall question.

REBOOT then install the YAESU USB drivers from the YAESU FT-991 files section.

Then restart FLDIGI and check the options below.

Very Bottom left on screen will say RTTY



OPERATION:

RECEIVE LEVEL ADJUSTMENT:

Set the 991 mode to DATA-USB using either the FLDIGI RIG MODE select box or

MODE button on the 991. Should be in DATA-USB or it will not transmit.

Turn up the 991 RF gain control, then use the WINDOWS mixer record control the USB AUDIO CODEC to turn down the waterfall shows mostly blue with some yellow noise spots.

TRANSMIT LEVEL ADJUSTMENT:

Hit the 991 F button, shift through function option and set MONI to on. Adjust to 50

ON FLDIGI, Push the tune button (upper right hand corner of window). You should hear a

Steady tone from the radio speaker. Turn MONI down for a comfortable level.

Using the Windows Mixer for Playback Device, turn down the USB AUDIO CODEC playback slider to show 50 watts on the 991 power meter. Then select the ALC meter and press the DT GAIN button and adjust the MULTI KNOB for no ALC indication. (you may use the DT gain for fine level corrections during operation. Adjusting the RF GAIN will be used a lot during receive.

UNKEY FLDIGI



FT-991 FUNCTION ADJUSTMENTS

Hit the F button on the 991. Shift the options buttons until you find NAR/WIDE button.

SET IT TO WIDE.

Now move the options buttons until you find the WIDTH button. Press it to turn and turn

The MULT knob until the width reads 3000HZ. (this will also be used in receive mode for fine adjustments.)

This should show a blue background on the FLDIGI waterfall from about 200 to 3000 HZ.

You should be ready to operate FLDIGI. (turn off the MONI if you wish.) I like it on.

If you save this frequency to a memory, the DATA-USB Mode and the function selections will all be saved.

Disclaimer: it was on original write up. AT YOUR OWN RISK.It worked for me.

Some of my additional experiences note.

DATA-USB is set under the freq readout on FLDIGI I keep it set to that for everything.

FLDIGI SCREEN under the freq readout there is a option: OP MODE. This is where I set CW, RTTY, and packet modes.

As you change these modes the lower LEFT corner will reflect the change.

The 991 RF gain I use to control the waterfall blue yellow issues. TO much gain to much yellow.

Time practice will get you going. MACROS you will reset and use your own. I have never used SOUND card modes before, I always used HARDWARE. Very impressed with these current programs.
