Hello Alain,

I am still having the same issue.  It is exactly the same for my FLEX 6400 and my ELAD FM DUO so it must be something simple that I am not doing to enable PTT using these radios.  I am able to manually click on TX, in the radio section of HRD, and both radios will go into TX mode.  In addition, I have full audio capability in terms of decoding and I do have rig control, for both radios, where I can switch bands, increase volume, etc. from HRD.

Please advise.
