Problem Recording WAV Files with Flex 6600M

Al Dewey

I listed a similar question as a "Question" but received no response either here or on the N1MM Reflector so I will try it again listing it as a "Problem".  

I am simply trying to record some .WAV files using the Mic plugged into my Flex 6600M and the DAX interface with my computer.  I have tried both N1MM + and Audacity with similar results.  I define the Microphone as "DAX Mic Audio (Flex Radio Systems) and the playback device as DAX Audio TX (Flex Radio Systems) with the CODEC box checked
.

My DAX Control Panel shows audio in the MIC Stream when I am talking.  However, when I play the WAV file just recorded, there is no audio in the TX Stream and the WAV file has no audio in it.   I am certain that I have the WAV file identified and located correctly because, if I replace it with an good WAV file (using the same name and location), I can play the WAV file and I hear (and see) it in the TX Stream.


I try the same thing with Audacity with the same result.

If I use a separate microphone plugged directly into the computer, all works fine.  But if I try to record with the microphone plugged into the radio (and use DAX Mic Audio), it does not work.


Something must be missing but I'll be darned if I can figure it out.

I am using version 2.3.9 of Flex Software.

Any suggestions appreciated.

Why does it matter whether its a M or non M radio?  I do not think it makes a difference... He is using DAX.

Craig;

No - I do NOT see the audio waveform when I am recording in Audacity.  However, I DO see the MIC Stream modulating in the DAX Control Panel when I talk but only if I have PTT (i.e. foot switch pressed).  If I engage the VOX on the 6600M, I do not need to press PTT and the radio will modulate while I am talking.  Still, I do not see the waveform in Audicity.

If I change the Microphone in Audacity to something else (the WebCam microphone for example), I DO the audio waveform in Audicity no problem.  And I can play it back through the radio.

But, of course, my intent to is use the 6600M microphone so the recorded message and my talking during the contest will sound the same.

It;s got me stumped so far.

Andy and all;

I finally got this issue resolved.  It turned out to be a bad install of the DAX Drivers.  Don, N4ZZ offered to help me find the problem.  All the N1MM+ setup and Flex 6600M setup was fine and matched his.  He then suggested I look at the Windows Sound properties for the various DAX drivers (TX, MIC, RX, and IQ).  We noticed that, when I looked at the properties of the TX and MIC drivers when calling up Windows SOUND properties, no audio was indicated on the little bar graph when I spoke.  I overlooked checking this because the indicators on the Flex DAX control panel DID show audio when I spoke so I thought all was well.

Thinking back, I did have some issues installing SMART SDR version 2.3.9.  After the install, I would get "driver errors" when calling up the DAX application.  I resolved this solution be uninstalling and reinstalling each of the TX, RX, MIC, and IQ DAX drivers.  But they must have not installed correctly even though the error messages went away.  When I re-installed these four drivers today, it took me multiple times.  I would uninstall / reinstall one of the drivers and there would then be a driver error in one of the others.  After several installs and many re-boots, everything must have finally took as it is working fine now.

Thanks again for all who helped me on this.
