Yaesu 991a setup

Will DigiRig work with Yaesu 991a?

Normally there is no need for that.
FT-991A comes with the internal interface, just use a USB connector directly to computer.
More info here:

Transceivers that do not require external sound card

I’m regularly getting questions about Digirig cables/configuration for the transceivers that already have soundcard/CAT onboard and do not require any additional hardware for digital modes. The frequently mentioned models are: ICOM IC-705 ICOM IC-7100 ICOM IC-7200 ICOM IC-7300 ICOM IC-7600 Yaesu FT-991A Yaesu FT-710 Yaesu FTDX10 Yaesu FTDX3000 Xiegu X6100 Please suggest the additions to the list and I’ll maintain it.

My Yaesu FT991A took a lightning strike surge through the USB port. Everything else still works. If you had a cable that would allow me to use the RTTY port with my DigiRig maybe I could resurrect the digital modes without needing the internal sound card serviced. What patch cord would work?
Or maybe if you have a mic plug patch cord I could at least get the tones into the transmitter.

Yes, give this kit a try with Digirig in RS-232 configuration:

Kenwood TS-480 cords for Digirig Mobile

I have done as you suggest. I am using the cables now. It is sending the tones out over the air. The tones may be over driven. I am not able to adjust the levels in Vara FM. Microphone and speakers levels don’t change the levels in Vara the way they should. When I check the driver properties “USB PnP Sound Device” there is no adjustments available. I have no control of the levels.

I have no control of the levels.

Congrats on your progress. If you are using Windows 11, try mmsys.cpl from the command prompt to get an interface to the USB devices for setting levels and turning off AGC(Automatic Gain Control.) AGC must be off.

The internal sound card in my 991a is also bad. The cables for the TS-480 will work for the 991A?

[K0TX]

Yes, your kit will consist of TS-480 cables, Digirig in RS-232 configuration and a USB cable.

K0TX, Greetings - I know this is an older thread, but I wanted to explain why I am looking for the correct cable to use the digirig mobile with an FT-991A. In ARES, I use a lot of Winlink with VARA FM, the problem with the internal soundcard of the FT-911A for FM communications is it only works with FM narrowband - it will not do FM wideband - I have almost a dozen digipeaters for winlink FM near me, only 1 is on FM Narrowband - and it is 46 miles away…

while i’m not answering your actual question first, , i will start by saying that a narrow client will connect to a wide VARA gateway.

it’s not like 1200/9600 packet.

now, for the cable, it looks like that yaesu has a ‘standard’ 6 pin mini din ‘packet’ jack.
that would be what i would use with a digirig mobile if the 991a has a 1200/9600bps selection for that 6 pin mini din.

good luck
