OK, I'm thoroughly confused.

I have VIA P25 trunked systems on my SDS100. In addition, I still have the "old" EDACS system on my SDS100.

I also have a BCD996XT with the P25 trunked system programmed. I also still have the old EDACS systems on this radio.

The only thing that seems fairly consistent with reception is my BCD996XT with the old EDACS system running. It receives transmissions and tracks conversations. This is programmed as an EDACS system.

My SDS100 on P25 doesn't hear some of the same conversations that the BCD996XT EDACS hears.

I understood when RR took down the EDACS site information that EDACS had been decomissioned. (The EDACS system operates on the same frequencies as P25 although uses fewer.) How can I track EDACS if it has been taken down? They couldn't coexist on the same frequencies but I guess the admin could have dedicated some channels to keep EDACS going and others for only P25. I am sure they probably have a mix of radios on their systems so their is still some transition?

If you are still reading this then this might be relevant:

EDACS on BCD996XT:
(This radio does not support P25P2 I don't believe)
SYSTEM TYPE: EDACS narrow/wide
SITE TYPE Medical Center EDACS standard/wide ...six channels programmed
SITE TYPE Lions EDACS standard/wide ...control channel only checked...six channels programmed
The radio ID reported on the scanner match the bus numbers used when reported by voice and are the actual bus numbers I believe.
In any event, this leads me to believe it is decoding the information correctly.

Could it be this system is not deactivated and somehow mixed with the P25p2 system? I just can't find a consistent pattern except the EDACS on the BCD996XT seems to track fixed routes talk groups just fine. I ocassionally just hear a digital transmission so maybe it isn't always decoding but this is rare.

Any smart people in the room?

Thanks!

Booth Towers EDACS/P25 Have 1-CC
and 4-Voice CH at this time

By the way The 996xt is (not a phase 2 Scanner you need 996P2

As the VIA's EDACS system is no longer in the database used by the SDS100, but you still have it programmed, these items are what I'd check to see why the SDS misses some EDACS transmissions that the 996XT receives:

For the SDS100, when you originally programmed the VIA EDACS system, did you append it from the database? (That would have been before it was marked Deprecated & removed from the database for the HP series scanners.) Or did you manually program it based on what the database showed at the time you got your SDS100?

Make sure that the frequencies & LCNs you have programmed in the 996XT for the EDACS system match what is programmed in the SDS100.

Double check your service types that are enabled on the SDS100. One of the most common ways that radio traffic is "missed" on one of the database scanners is that one or more service types were in use, but not enabled in your Sentinel profile.

As you already noted, the 996XT cannot handle P25 Phase II. Looking at both the old EDACS system as well as the new P25 Phase system, apparently the TGIDs on the Phase II system use the Decimal version of the EDACS TGIDs, prefixed with 45. So, Bus lines Dispatch 1 is AFS 04-041, Decimal TGID 545. On the Phase II system, that TGID is 45545.

SDS100 needs to be your (P25 P2)
Choice

Use any other scanner for edacs
not the SDS100 it does not rx the best on edacs

it not you or your data its the scanner used to rx and it specs

VIA Edacs Works very well
on BC245/Pro-92/Pro-96

The Radio is a phone like system
you dont hear the radio on the
bus

The radio is controled by the data $MCC-X

BUSES May use options:
RTT=Request to talk
PRTT=Priority Request to talk
COVERT RED=EMER button on MDT

its tied into a harness that controls
the radio and assigned ch

Also the bus in case of hijack it has a black button on side the driver side to change sign to
"CALL POLICE"
