How can I record in VOX mode when a supervisory tone is present from an external source?
You have two options. You can run the line in contact closure mode if you have a dry contact recording control output from your console. Or, you can set the radio to disable the supervisory tone so it doesn’t trop the VOX. You can also filter out the tone (It’s typically 2700Hz), but audio quality will be significantly degraded, so we don’t recommend that.
