Intermittent VOX

Running 6400 2.6.5

I am having ongoing issues with VOX mysteriously not working. I have reset my database, checked all mic connections and the problem still crops up intermittently. A work around is to close and restart software? That works most of the time. Is this a software bug or a possible hardware issue?

Thanks, 73 de Dan KG0AQ

    Hi Dan, it could be that you are just at the edge of some adjustments. I would start by turning DEXP all the way down to see if that helps. If not, try turning up the VOX gain. If it chops in and out, try setting the delay up a bit.

    When this happens check that the DAX button is not selected. I have had this problem a few times when changing from FT8 digital to SSB operation.

    Len & John,

    I have tried both of your suggestions prior and nothing changes the behavior other than a software restart. It is like VOX does not exist.

    Could it be a third party program causing this behavior? I run DDutil and Stacks 3 all the time.

    Thanks 73,

    I run DDUtil, and have not had any problems. Not sure about Stacks 3. Try without it to see if the behavior changes. If not, it is probably time to submit a HelpDesk ticket.

    Serge,


    Thanks for posting these links. I missed these in my original search. It does appear that others are having my same issue. Unless someone from Flex can come up with a solution to my issue I will wait for a fix to defect number #7724 someday. At least the restart solves my issue for now. BTW, using a Heil PR-781 with +20db bias on.

    Thanks again, 73 de Dan KG0AQ

    kinda same issue here, i know about Dax issue and have it off. but sometimes during ragchew it just unkeys and you have to take a breath and it will start back up, not too bad but it does get aggravating!

    Thanks!

    @KI4P Hi Richard,

    I have the exact same problem. I am NCS for the Wolverine Single Sideband Net (3935Khz) on Saturday evenings. I use VOX. This 6400M has the craziest VOX I have ever seen. First I can't find an anti-vox control. Second the VOX just quits. I have to cup my hand around the mic to get it back. What gives?

    For those having Vox issues:

    First, I need to see your settings either from SmartSDR or your FrontPanel. If you have to, take a picture of it.

    What is the Vox gain set to and Vox delay?

    Next, when you drop out, keep an eye on your Audio Level meter. Are you peaking to -5db or so? Or, did you drop way down.

    I also need to know how you are connected to the radio. LAN? Front Panel Maestro or SmartLink.

    I would start with making sure you Mic Levels are set correctly.

    Next, start with the Vox Gain and Vox delay set to about 1/2 way.



    All the above is critical so we can attempt to recreate it.
