[Scan-DC] P25 Phase 2

[Andrew Clegg]

Thanks Mike and David. For some reason I thought the P25 standard would have long since been finished and matured, but obviously not!

Cheers,
Andy

  Andy,

Sorry about the link problem -- it worked OK for me.

The last line of the article adresses the 6.25 kHz issue, they will get 
the FCC required 6.25 KHz equivalent by creating two paths in one 12.5 
kHz channel -- so no, there is no 6.25 kHz channel.  Meeting the FCC 
requirement is the key here -- they do not need to do 6.25 if they can 
put two audio paths in one 12.5 channnel.  This is what Motorola is 
doing with its MOTOTRBO radios.  However it's not over 'til it's over!

David

Although it still isn't clear from this article, it appears that to meet 
a "6.25 kHz equivalent," they are instead proposing a 12.5 kHz signal 
that carries two separate time slots. So, still, no actual 6.25 kHz 
plan, as far as I can tell.

I don't remember who asked about the P25 Phase 2, but here is some info
from the APCO conference that is going on this week in Kansas City:
