It sounds like the trunktrackers are ignorin the OSWs of what talkgroups are
included in the MSel (or APB - whatever you want to call it) that
immediately precedes the MSel.  It shouldn't be rocket science to add that
feature to the radio (I wouldn't think, anyway....i'm not a scanner designer
guru ;) ).  But MSel and ATG are two features that, for now, scanners can't
manipulate (key word is MANIPULATE - they can receive the ATG, but it won't
act like an ATG should).  On an ATG, what channels receive it are dependent
on the zone that the ATG is programmed in to, so there may never be the
capability of the scanner to truly receive an ATG.  So there are SOME
features that won't ever be available to scanner users and that's just an
unfortunate reality sometimes :)

Greetings All,
      To the folks at GRE working on the PRO-96.  To advise
you.   Here in St Louis, Mo the 'STATUS BIT' features don't
exactly work in the normal manner here.   Example:

I 'HOLD' monitor District 1 & 2 (Only).(STATUS BIT mode 'ON')
Say the 'District 1 & 2' Dispatcher goes 'All Points'.  1 & 2
talkgroup is  57360.  So, when the 1 & 2 Dispatcher goes
out with an APB, you'd expect that 57367 would come out
over the data channel, right?  Well, NOT here in St Louis.

It could be any of the Dispatch talkgroups+7 (the status
bit).  One thing I can tell you.  Even though our trunktrackers
do not receive it correctly.  The actual system radios:

- stx-800s (most) & XTS-3000s (few)

They receive them correctly (everytime). The officer's radios
receive all APBs correctly.  Its only our trunktrackers that
do not.  So the 'STATUS BIT' mode on the Uniden models
is completely useless for us in St Louis, Mo

Also, using the same example above, monitoring 1 & 2.  Dist
1 & 2  is quiet, not much going on (talkgroup not active).  Then
the District 4 & 5 dispatcher goes out with an APB.  With our
Trunktrackers, we never hear the APB from 4 & 5.  The APB
goes out with the talkgroup ID of 57719 (which is the INFO A
talkgroup+7)  But, at the same time.  All officers with XTS-3000
& STX-800 radios receive the broadcast just fine.  (Not a
selective APB ; we very rarely, if ever do selective APBs)

This is a very prominent problem.  Occuring 3 out of every 4
times, day or night, round the clock 24/7.

Conclusion, the officers radios receive the APBs just fine.  Its
only our Trunktrackers that do not.  Before the PRO-96 ships
later this year, could someone from GRE investigate this matter.
I hope the problem is not unique.  I do not consider the St Louis
City Police Type II Motorola TRS to be that special, or differant
from all other systems.  Obviously, the problem lies in our
trunktrackers, not the police radios.  Our scanners are ignoring
something in the Data Channel's data stream.
