Thanks to Rich, N9JIG, who posted several months back about discriminator taps for the 536HP only a few days after receiving his scanner. Well I decided to tap one of my 536HPs today (Uniden will know which one if I have to send it in for anything, and I'm sure, tell me it is no longer under warranty. C'est la vie. I have one other 536HP right now that will be under warranty. Some of you may think I'm nuts.).
Anyway, the discriminator tap seems to be working well. About the same as my tap on one of my 996XTs and the IF output from my 1080. Better than I can get with RTL dongles and SDRSharp raw audio. Working well with DSD+ right now decoding P25 and NXDN here in Los Angeles.
Now to my point, the 536HP "native" P25 decoding of the LAPD and LA ICIS P25 audio is much better than that with DSD+. On the stronger stations or TGs, the P25 decoding via the tap/DSD+ is quite good, but the 536HP native decoding sounds better. However, for weaker channels, DSD+ is floundering with errors, lousy decode, while the 536HP native decode is still very good.
This mirrors my experience with the 436HP/536HP vs. all my other scanners listed below. When the going gets rough, the x36HPs do the best job of digital decoding for me here in the Los Angeles area. Yes, the GRE/RS/WS1080 sound a bit better (more treble), but on the weaker ones, the x36HPs pull/decode stuff that the others cannot. I have been using the HP2 for a couple of weeks. The P25 is pretty good, but again, in the weak signal cases, my x36HPs do better.
Thought I would post this, because here is an example, at least in my experience, where the P25 decode from the 536HP is better than with DSD+ using the discriminator audio of the 536HP.
