Pro-106 Trunk Symbol Flash

[skatertj]

New user to the 106 and havent found this answer yet. Should the 106 Trunk symbol flash when it receives a trunking signal or should it be completely gone? It stays steady while scanning, only flashing when it goes from third scanlist back to first but when an officer talks, it flashes fast and is faint. Should it be steady on or off?

Im thinking the T should stay on steady when your recieving the trunking channel if you have a good signal. If you have a poor signal it will flash like you say and it will appear to flash while the scanner is scanning the trunking system and the signal is poor. I have a trunking system that is barely out of range and that is the way it acts. Somedays the signal comes in a little better and somedays its gone.

Ok, well i have full bars when receiving the signals and its solid when scanning, but as soon as an officer keys up and talks, it flashes. In this video(psr-500), his scanner has no T symbol when the officer talks. Mine flashes like his does when its scanning as this 500 is doing, but when the symbol on the 500 goes away, mine stays and flashes but very faint. Hope that makes sense.

I dont know about that. Have you tried to update the firmware on it? I see your not new here and you probably had another scanner. Did you have it programmed on another scanner? What system is it?

[asurnin]

If you are scanning a Multi-site system, the T will flash as its hitting between active CCs within your range and other channels that may not be active or have a decent decode rate.

Yes, it's rather normal and does not seem to affect the scanners performance.

Yea actually just updated the firmware about an hour ago but it was doing it before the update. I am scanning the OKWIN system for Tulsa and Coweta. My other scanner is programmed for this system, but it doesnt have the same display. Its an older model so it doesnt have a T symbol or signal strength bar. Im about to get the 106 replaced with another because it has a ringing noise sometimes when it receives signals and my other scanner doesnt do this. Maybe this scanner just isnt all there... haha

[skatertj]

Asurnin, this is a pretty big system. The main tulsa site has 4 control channels in it. All 4 are programmed in the scanner, but my coweta site has one CC and it flashes too.

[jfhtm350]

The closest trunked system to me is barely out of range, but it tries to pick it up now and the T will stay lit up when a talkgroup appears. I just looked at it.

The T will not show at all if your not recieving the CC.

[asurnin]

I always thought it was normal behavior. As long as you're not missing any major traffic, I wouldn't worry about it. Mine performs similar to your observations.

Sometimes I just get all bars (no S and no T) while someone is talking, but I think that can be due to some front end overload.

[jfhtm350]

You can program the 106 to sound an alarm when it recieves a signal or breaks squelch. You may want to check and see if you have that programmed in.
The alarms in Win500 are:
None
Chirp
Hi-Lo
Alert
Ring
2 Chirp
Fast Hi-Lo
DTMF#

I dont have any alerts on for talkgroups. Could just be something that is normal! lol

Depending on the system you are monitoring, the T may flicker or not light up at all when you are monitoring a talkgroup with voice traffic.

On new P25 and Motorola trunking systems there is now a slow/limited data stream flowing behind the voice traffic on each channel. It does not contain the full data stream of the control channel; but talkgroup to channel calls, so that radios may have a priority channel selected and still see the call when monitoring voice traffic on another talkgroup.

When the Pro 106 (GRE 500, 600, 800 scanners) see this slow data stream on a voice channel they flicker the T. When on a control channel the T is solid, and when no data is available (conventional, moving towers in trunk, voice channel on edacs, old motorola, etc) there is no T.

[jfhtm350]

No. I dont hear any rings or beeps other than the ocassional roger beep from some users radio. Post a small size mp3 or wma file of the noise. Im on dial up so easy with the file size.

themadman- That makes alot of sense when you put it like that!

[N1BHH]

I will mention this again. It's real simple. When a Motorola trunk system control channel is scanned by during scanning. the T will show. When you are stopped on a trunk object during scan, the T will flicker while there is activity on that object. If you manually select an object the T will stay on until a signal is heard on that object, it will then flicker. Obviously if no T shows at all during scanning or stopping on an object, that means you radio isn't "hearing" a control channel signal.

My buddy has a Pro 197 and it flashes the T on and off fast when its a Analog Talkgroup on the Voice Channels and doesnt when its a Digital Talkgroup on the Voice Channels. Thats what Ive noticed before on his pro 197. This I noticed on Motorola Trunking systems.

Also My PSR 310 flashes when on a Analog talkgroup on a motorola trunking system, not sure about on the EDACS system I pick up, I will have to check that out

Thanks for the reply guys!!! I appreciate all the responses!
