P25 sound quality better than DMR

[jeanlikethis]

Hi, I got both radios.

I am impressed p25 has a better sound quality than DMR?

Any one has the same feeling? Thanks.

There are way too many variables to make an objective determination, so it's all subjective opinion. If you're listening to P25 with a crappy radio and the person on the other end is swallowing the mic, it's going to sound awful. If you're listening with a good quality DMR radio and everyone is using best practices for speaking into the mic, it'll sound great. At the end of the day, they both use the same AMBE+2 vocoder when operating in TDMA mode. FDMA on P25 is a crapshoot depending on the vintage of the radios, they may only be capable of the older IMBE vocoder.

I got XPR7550 talk to XPR7550 and XTS2500 to XTS2500.

Same distance and same people, same frequency. Always feel XTS is crystal clear while XPR some time distorted much.

Could also be a tuning issue on one or both of the XPR radios.
But @GTR8000 nailed it in his explanation.

The other issue is people using cheap Chinese radios on DMR, people changing audio settings on both DMR and P25, too many variables as @GTR8000 mentions. I remember a first aid squad in Morris County sounded way over-modulated on the County. Probably someone inexperienced cranking up the gain too high...they were notified with the specific radio IDs that were the issue and it disappeared shortly thereafter. So YMMV with either or. For me personally, my ear was tuned to P25 FDMA for however long its been around until TDMA systems rolled out. Now I use them everyday and from a capacity perspective, you can't beat it. But I still like the sound of FMDA better. DMR....eh. The hammies love it, I don't believe it belongs in public safety personally, but costs always comes into play.
