How long is the recording buffer in the DVR for incoming and outgoing audio?
There are 8 memories. Each memory is 10 seconds. A countdown timer appears when you are recording to remind you how much time is left. In addition there is an off-air RX record loop. Rx record is a 90-second loop, so you can play back the last 90 seconds. You can loop this buffer and then stop it at any time to replay the last 90 seconds of RX audio.
