6600M TX Monitor Not Working when VOX enabled

When operating VOX with either the 6600M (or 6600) I notice that the TX Monitor function cannot be used.  We confirmed this on both the 6600 and 6600M, likely affects the 6400 as well.  The TX Monitor function seems to work only in conjunction with the PTT input.  Firmware 2.1.32.104  Anyone else?
Thanks!!

Just tested on my 6600M (v2.1.32).  In VOX mode,  the monitor works both from speakers as well as from the headset. One thing i did notice i did have to turn the monitor level to almost to max before hearing my voice.

TX MON is still not working with VOX here.  It only works with PTT.  Upgraded to 2.1.33 last night, no change.  VOX works OK but TX MON does not.  Doesn't matter whether MON is enabled or not, no TX MON here anytime my VOX is enabled.

Bill is this on software, M radio or both?

This is on the M radio.  I've also tried disabling DEXP with no change.  The VOX works fine whenever selected, it's just that the TX MON will not work under any circumstances when VOX is enabled... but it will work if I hit the PTT button.

Seems as tho the MON is tracking the PTT input and not the VOX key line

Bill, Did you try using 1/8 pwr speaker output jack? My 6600M running though PC didn't work until I used the 1/8 pwr output jack into my powered speakers.

I have a set of powered speakers connected to the pwr spkr output jack tho I usually keeo those muted,  99% of my operations are on the headphones (for home noise abatement purposes).  As I posted above VOX works fine, just that TX MON remains disabled whenever VOX is enabled.  The button icon indicates TX Mon is enabled, tho it's not.  The TX MON only works when the PTT switch is triggered (even on VOX mode, hit the PTT button then MON works, but only for the duration the ptt button is held.  If PTT is released then MON stops even tho the radio may remain keyed as a result of VOX activity.  Bizarre,  This is an M radio (6600M) S/W 2.1.33 (and prior had same issue)

I'm seeing the same problem still (Sept 2018).  Monitor works OK when using PTT but not with VOX.

I'm recording the audio out of the powered speaker 1/8" output (through a mixer). Flex 6600 with the latest software.

One factor: I did have DAX enabled in order to potentially play audio from N1MM+.

I recorded my participation in the Worked All Europe SSB contest earlier this month and you can hear the difference when I switch from PTT to VOX. I got nothing out from my microphone on my recording and had to edit in audio from one of the cameras I was using (a real pain).

Would like to have this fixed please!
