I do not think any of use know for sure. Paul would likely need to answer that question and I expect that a Firmware change would be needed to disable the Replay feature.Is there a way to turn the record feature OFF?
Uniden should have used volatile memory for the Replay feature and even the actual record feature then batch recorded to the SD card. The only issue with this is during a unexpected shut down due to power loss of AC power or battery avalanching.
Not sure if the HP-1 plays differently then the x46HP?? Not sure if the HP-1 units have had issues like the x46HP's?
I have not had an issue with my HP1 so far, but I have not been using the Record feature often, meaning the actual record feature but Replay is enabled by default.
