If you have multiple DataLink interfaces connected to your PC then Device manager will show each codec;
If you run several instances of DM780 then each should be configured to use one of the codecs, note that DM780
numbers them for you. Although you can run many instances of HRD there is no provision in DM780 (at time of writing)
to save multiple configurations as “profiles” so you would need to make the selections each time you start multiple
instances of the program.
Remote operation.
PTT is normally generated automatically by the interface whenever it receives an audio signal.
If you intend to operate your radio remotely using Skype, (Full Duplex) you must disable the interfaces PTT line and operate PTT either via
CAT or via VOX. For operation with Skype you can simply remove any PTT line.
