Not sure if it's been mentioned, but here's an issue that I have found while monitoring my local P25 Phase I trunked radio system:
When you have the display settings set to show the Unit ID (either Unit ID and/or Unit ID Name), the scanner displays the Unit ID/Name correctly even on quick key ups after one user stops talking. There's no issue either when actively recording the transmissions. HOWEVER, when going back and replaying the recorded transmissions, the Unit ID/Name seems to get lost or can't keep up.
For example, when User A keys up, his UID will show, however when Control keys up, it will still show User A's UID, and then when User A keys up to reply, it will show Control's UID. This only seems to happen when users are talking back to back. The issue doesn't happen where there's "long" gaps between transmissions.
Again, this doesn't appear when the transmissions are happening live, only when replaying the recordings.
This didn't happen on the 1.05.01 firmware, and I've even decided to go back to that firmware for the time being.
Our local system is in the midst of a transition from SmartZone to P25 P1 and I enjoy tracking and logging the new UIDs. To do that, I leave the radio recording and then go back later and log what UIDs I have found and don't have remembered already. So the UID lag can mess that up.
