Not sure what LSM is but i have noticed if you put the scanner into a search, when it stops on control channels they are showing FM now unlike DG as it used to.
Griffin ga phase 1 scanning has ceased! Partly.

LSM is Linear Simulcast - used in big trunking networks when they transmit from several different points on the same frequency at the same time.
Anyway, if they are using LSM and you are in an area that 2 or more sites have overlapping coverage, most scanners have a difficult time decoding the different incoming signals - the 2-way radios on the system do it just fine. You will have broken & dirty audio.
As far as your FM vs DG goes: they may have combined the 2 separate systems and now some talk groups are Phase 2 and some are Phase 1. If that is the case, somebody with a P2 scanner and/or something like Unitrunker needs to listen and see if the control channel is assigning P2 traffic. Your P1 scanner will just show FM for any P2 traffic since it doesn't know what it is - just looks like static.

This system isn't that big. They have most likely went to the phase 2 as it has been in test mode since April I think

Just a suggestion, download Pro96com onto an available PC. You can use your 396 through the USB cable to the software. It enables you to monitor a signal to see if it is Phase I, or Phase II. It will also give you TGID's. You will be able to see if they are encrypted, or in the clear. That way, you'll be able to make up your mind on a radio

If that's so then why am i getting spotty reception? My scannet is not p2 capable so i shouldnt hear anything. Are you scanning this system? And if so is it clear as before? Just wanting to know before spending a load of money. Thanks

Phase II doesn't always mean TDMA TGID's to begin with.
Your spotty reception may be due to the antenna you're using on the scanner, or where it is positioned.
Are you using the duck that came with the scanner, or are you using a RS 800MHz antenna?
Is anyone monitoring the system with a Phase II capable scanner?
It can be followed using the software I listed in my last post. You'll at least see if the TGID's are Phase I or Phase II.

I am using the rs 800mhz antenna. I have not been able to find anyone with a phase 2 capable thats scanning the area. I am going to check out that software you speak of, is it hard to use, I'm a intermediate by no means expert level when it comes to scanning. Download the software and connect my pro106 to the computer then?
I have it connected what am i looking for? When i hear activity on the scanner Flavor is phase 1. Receive rate isnt getting higher than 60%

I tried to pro96 thing I couldn't even get mine too connect, did you leave it on decode for a while?
No not that long. I did it while on the analyze screen and in just regular scan mode. I didn't have a problem with it connecting. You read the manual on what to do before connecting the scanner?

Analyze mode is what I generally use unless the signal is strong.
On the screen view, there are 5 TGID's, and 11 RID's.
That means they are doing their testing in Phase I mode. The current flavor:lol:
There is a "Phase II" system near me, and they are using Phase I because not everyone on the system has radios capable of Phase II.
Hope this answers some questions.

I understand what ur saying but is there no way to get good clear scanning back? Or would i get clear if i go ahead and get a phase 2 scanner? Or will a phase 2 capable scanner possible sound just like it does now?

If you go to the database here, you will notice that Spaulding county has been updated.
Put in all of the red CC's. This might also mean it is a Harris system.
The TGID's are also listed. One is the SO Encrypted. The rest are 'D', which means that there are operating in PHASE I mode, not Phase II with a 'T' for TDMA.
Load them and monitor. Just remember, Phase II sites will have lower power. Make sure your squelch is set accordingly.

Thanks Larry. I'm trying my best to keep up with you. Funny thing is the new updated CC are what i already had in, thats what puzzled me as to what update if i was already running the new numbers. I am less than a mile from the closest tower and already have to use half squelch just to get what comes thru now, which isnt much now! So if phase 2 is weaker there really isnt a need to even try to scan it. I am in the county but when i go into the city, you would think signal gets better but it doesnt.

Have you tried a smaller antenna? Or, maybe one for VHF. No gain antennas. Try using the one that came with the scanner. The fact that you are so close to the tower, it may be overloading. I know that for my county, I can take the antenna off and still hear the system. To bad for me, the county is totally encrypted
Sorry if I throw a lot of stuff at you. I've been scanning for over forty years, and a ham for thirty. I just figure everyone understands at my level Took me a while to know what's what.

Do you have it programmed as P-25 AUTO?
Lots of signal loss and even some encrypted transmissions on one particular TGID.
Don't remember what page it's on, but get rid of the G on the screen. It's under ATTenuation.

Yes that system is all p25 auto. The encrypted channels were coming thru because it was on wildcard instead of scan. I got the G off screen
This is running pro96com while on analyze. What does this tell you Larry?
