PTT for Two Sound Card Programs Needed

I need to run two sound card programs simultaneously and jump between them without delay. Receiving is no problem by setting the software to listen to the same DAX channel.

However, my 6500 will only transmit from one sound card program...whichever was first started.  To transmit from the other sound card program, I have to exit and restart Smart SDR to free up the serial port.  I need to be able to transmit from either software program without this delay.

I have read the Smart CAD documentation but cannot figure out how to make this happen.

I only need PTT functionality...no other CAT functions. Specifically, the sound card programs are HRD6/DM780 and MS-DMT.

Thanks for your expert help.

Can't speak directly to the specific programs, but you should be able to set up as many PTT ports as you like in SmartCAT and assign them to whatever programs you like. Say COM6 to one app, COM7 to another.
