Does anyone foresee in the future ( hopefully near not far) that there will be a Provoice scanner invented? So nobody has to go through digital speech decoding.
The key is, as it always has been, they need to release the technology to the scanner manufacturers, then they can build a scanner to decode the signals. I have read de bates on whether Provoice is considered "encryption" therefor illegal to decode, but that's an other debate for another time
I used to have a provoice system where I lived. I was able to trunk rack and hear everything using two bct-8 scanners with a discriminator tap on both. One scanner feed unitrunker. and unitrunker controlled the other scanner which also had a tap. that tap fed dsd on my computer. and unitrunker would follow it just like a radio and audio was excellent it worked great up until the day the system went offline.
P25 Phase II will be mandated for the 700 MHz spectrum by 2017, per the FCC's 6.25 kHz efficiency rules (47 CFR 90.535).
I was under the impression they'd backed off on this (or are least are considering it).
P-25 systems that are buildout after January 1 2015 must operate on 700mhz in at a minimum of phase 1 status.
Which is 12.5kHz.
...Phase 2 status which is 6.25 kHz.
