Mic and speaker audio for setup help 6600 via the PC

Raul Pla

in Computers and Operating Systems

With other details set up by now its time to place the 6600 and PGXL away from the office/shack at home. In the garage. Ive bought a good USB mic for it. I need the detailed setup info for transmit voice audio and fore the receive audio.

I welcome any recommended info docs or YouTube videos, for Win-11.

Right now the mic keys the radio PTT if I set VOX. but no audio transmits. Also no audio TX if I click MOX on SSB. DAX streams show up as active.

Any help high appreciated.

    You will likely get SSB output if you put the radio into TX using MOX (not PTT on the radio).

    If that works, they the HaliKey should solve your issues.

    If I hit MOX it keys the radio but no audio or power out. If I choose VOX the mic keys the radio and I see a tall column on the signal screen, but to audio or power out.

    The radio is till on the PC desk so I can use the FHM-3 thats conected to it. But moving the radio to the garage I need to use all via PC.

    Take a look at this. Its probably the DAX mic stream off? but it doesnt just turn ON when I hit that yellow button. Clicking that and it goes gray or yellow, never blue

    There can be many things:

    • Check mode
    • DAX is not required, so you can terminate it up
    • Make sure TX DAX is not on
    • Reboot the radio and test again.

    Mode was USB so thats fine. I thought DAX is the audio interface or manager between the PC and the radio. I dont know what terminate up means. Is there a YT video you know of that touches on this?

    The TX DAX turns off in the slice flag? or where?

    For Voice, DAX is not required. That is only for digital modes and using it to send audio from things like N1MM Voice Keyer.

    For using PC Audio, it is discussed in this video on using a radio remotely (which is the same thing when you aren't using a MIC plugged into the radio).
