I didn't want to believe it or really compare the two but....earlier I was updating my 536 and I fely my GRE PSR 800 staring at me so I plugged it in,powered up again and wow oh boy, it is crisper audio wise then the 536,scans way faster,less static,..,ect. I had the two of them about four feet from each other and the 800 picked up about 6 more hits while the 536 well kinda was stuck on stupid. I just sat there and realized I spent $600.00 on what appears to be a inferior radio. I have no clue what to do because I truly wanted a base unit scanner that does p25 phase2 and don't really want to sell the new Uniden and get killed on shst I paid as opposed to whst I'm going to get now that the cat is out the bag. I hope to God that there will be a firmware update of by some Devine intervention I or our esteemed colleagues here can figure out to get the 536's preform like the 800.
