Red Wave Radio

I've had no problems working my pro-91 in trunk mode, but recently got
pro-95 and, yes, I read the instructions more than 3 times, I'm
still confused.

I can set individual channels AM, FM, Motorola, or ED mode; and I can
set a bank into non-trunk; MO, or ED mode. I've tried every combination,

and get confusing results.

The only way that seemed to work is putting each freqs. into MO but
leaving bank non-trunked. Even put in text for IDs, they show up fine,
but data channel(s?) come through (MO:None and ID 976 for some reason)

Radio Shack tutorials (for other trunk scanners) were no help...

Help!

Notes:

If channels are in MO mode, and bank in MO mode, I get nothing.
If channels are in MO mode, and bank in Non-trunked mode, I get MOT talk
IDs, but also get data noise
If channels are in FM mode, and bank in MO or non-trunked mode, I get
conventional scan (no IDs, data noise, scans same as voice)

Something is strange with it...

My Pro-93 has a glitch in it that may be related to yours.    When the scanner
is properly programmed and you are actively listening to ANY transmission
(trunked or not), something in the software will cause the scanner to stop on
the Motorola data channel as if you are in manual mode listening to the
frequency the current data channel is operating on:  if you attempt to
(de)activate a channel bank, add/remove the Delay for that particular active
channel, or add/remove the 'attenuator' function for that active channel.  mt
Pro-93 is version 1.00.  Maybe this glitch was fixed in later version.  To
remedy this:  simply press function 5 (to open or close the bank the data
channel is coming in on), allow the scanner to start scanning.  Then manually
select any channel in the bank where the Motorola data channel is, then press
function 5 to open/close the bank to however you had it.  Press scan and
everything should be fine.  
To prevent this, DO NOT perform the 3 steps mentioned above (that initially
caused the problem).

Thanks, Eric. I put my old pro-91 and the new pro-95 side-by-side and fooled with
this more.

The data channel, (a loud ***-like noise) is correctly masked on both.

The pro-91 manual says, (page 48), "If a channel activity bar turns on but you do
not hear a conversation, the channel is probably being used for a telephone
interconnect or a private call... your scanner does not monitor these types of
calls.)

Where the pro-91 displays an activity bar, the pro-95 stops on the channel and I
hear "hiss - pause - hiss - pause - hiss, etc.) While this is happening, if a
voice channel begins, the pro-91 will monitor it (audio) even while the other
activity bar is up, and the pro-95 is still stuck monitoring the "hiss", missing
the activity on the voice channel! (It does show both the "hiss" and the voice
talk ID's, alternating)

Also... If I manually monitor the data channel, and watch the talk ID,
it continually sounds like the data channel would, but the "MOT:"
talk ID changes back and forth from CNTRL to 00976 -- the ID of
the "hisser" that gets monitored when scanning...

I wonder if this is a legitimate "talkgroup" used for data communication.  
Some systems have a data talkgroup.  Bummer, since it makes open mode
scanning a hassle.

I'm guessing that it is a legitimate "talkgroup" -- but for digital
communications -- it sounds like the hiss of higher speed modems. It doesn't
sound like a voice scrambler. Bummer indeed.

What surprises me is when I put my pro-91 and pro-95 side-by-side. The 91
"lights" a block indicating activity, but it keeps scanning (watching the
data channel) for an active voice channel. On the 95, when it is already in
scan mode, it stops on this 00976 "hiss" channel, I push scan, if finds the
00016 that the 91 found. Also, if I begin a trunk scan on both at the same
time, the 91 gets the data channel and monitors the 00016 active channel
faster, to me, much faster.

It is possible the 91 ignores any data talkgroups, while the 95 will find
them.  I also have a pro-91, but no systems to test this theory, since all
the systems local to me have their data traffic on a separate system.
