Running a 6700, Maestro with 1.9.13.  Issue is Writelog Audio and hardware PTT.  It looks like a known issue is hardware PTT kills DAX - I am assuming that the MOX button is really a software PTT becuase it works fine.  In a contesting situation at VHF/UHF we use hardware PTT to key a sequencer so we really can't use VOX on phone.  Sure would be nice if hardware PTT left DAX in whatever state it was in -"On" or "Off".

Hardware PTT overrides DAX. When operating in a non DIGx mode, using a hardware PTT such as the RCA PTT input on the back panel will override the input of DAX. This feature allows the user to override the DAX input with a PTT switch connected directly to the radio.  

This is referenced in section 26.5.1 in the SmartSDR for Windows Software Users Guide.
