I've been comparing the 536HP to the PSR-800 and I noticed that the 536HP searches and scans slower. At first I thought this was the cause of missed conversations on the 536HP. Then held both scanners on the same channel and confirmed that there is a delay with the 536HP. Another issues is, why would Uniden release the 536HP without the Analyze mode available? It's been on the HP-1 ever since the Extreme version was released. There was no pressure from GRE/Whistler so what was the rush? No Analyze mode, no Siren App, No per channel record and audio is worse than the 996XT. I hope I have better luck with my 436HP when it arrives later this week. I'll be sending back the 536HP with 15% restocking fee or just sell it.
