Upman...P34 6.25

Upman,

I asked on Yahoo site regarding phase two for APCO 25 switching from 12.5 to 6.25

Will 996 need any updates for this change? And will it do both simultaneously?

The Phase II specification is still a work in progress. Until the Phase II specification is finalized, we can't make any claims to compatibility. Considering that Phase I was finalized in 1999 (or earlier) and real penetration of these systems has only happened in the last couple of years, I would not expect this to be a real issue for several years...but, of course, that depends on what the final specification ends up being (tentatively it looks to be two TDMA slots on a 12.5 kHz signal which would give the equivalent bandwidth efficiency of two seperate 6.25 kHz channels but the RF performance of the 12.5 kHz channel).

thanks

thanks to you and N_Jay for clearing this up
