VoiceMeeter

Using the FT-991/A USB audio port for voice input in Windows PC

Project goals

  • Use any standard USB computer headset or microphone connected to the computer to process voice audio before sending to radio

  • Use the radio hands-free and PTT via CAT, Vox, or external switch

  • Playback pre-recorded CQ calls

  • Record and playback sound from the radio

Software used

Tools are both "donationware" (free for personal use)

FT-991/A Menu settings

These are the settings needed to accept mike audio via USB port and use VOX PTT activation (if turned on via F-options.) Alternatively PTT can be achieved via CAT (this is what I use with my logging software Log4OM.)

  • 045 AM MIC SELECT -> REAR

  • 048 AM PORT SELECT -> USB

  • 074 FM MIC SELECT -> REAR

  • 077 FM PORT SELECT -> USB

  • 106 SSB MIC SELECT -> REAR

  • 109 SSB PORT SELECT -> USB

  • 142 VOX SELECT -> DATA

  • 146 DATA VOX GAIN -> 90

  • 147 DATA VOX DELAY -> 1000msec

USB Microphone tuned with the help of the fellow ham radio operators of Argentina-Link Fusion reflector.

Now I can:

  • select via the VoiceMeeter software console which mike I want to use for QSOs

  • switch the audio out between speakers or headset

  • record and play messages directly to the radio.
