Griffin ga phase 1 scanning has ceased! Partly.

[N8IAA]

This is running pro96com while on analyze. What does this tell you Larry?

It tells me that you have six Alternate CC's that function as Voice channels also and one CC. That there are two TGID's showing DT, which means that they are Digital, and not TDMA.
Your previous screen shot showed that there were 5 TGID's and 11 Radio ID's.
If you are saving your sessions on Pro96com, they are saved to Documents on the computer. That will show you when the TG's were active.
Are you receiving the system better now? I surely can't hear it in the N Metro area.

No its not picking up any better. The first picture was in scan mode and the second was in analyze. BCD325p2 is sounding the same. Didnt use software to program just put the cc's in. Not sure if that is how you do it if ita phase2 or not. Somethings obviously not right since that scanner is supposed to be capable. Go from one brick wall to another.

Would programming this system as an edacs be an option what is edacs? Trying to make sure I programmed this new Harris p25 joke in right?!

LSM is not the root of the problem though. The root of the problem is using a discriminator tap, rather than actually makingdesigning a receiver that is capable of properly decoding CQPSK. Uniden has failed on all accounts by refusing to acknowlege there receivers are crap.

The system is not the joke, the scanner is. With actual subscriber radios, it will sound a whole lot better than your crappy scanner.

Do not program it as an EDACS system, as it is not an EDACS system.

OK what good scanner would you recommend or subscriber radio as you put it!

 

[kayn1n32008]

Almost anything BUT a scanner. To use a subscriber you will need a Motorola radio, as far a I know Harris, Kenwood, Tait and EF Johnson subscribers can not be programmed to passivly monitor a P25 syatem

With Motorola gear you can, when done correctly, program them for passive monitoring. Nor something the newbe to Motorola should try.

So basically the Harris LSM phase 2 is not scannable, by a consumer scanner.

seth21w, search in the GA forum for Rome/Floyd county system. The same problems you are experiencing happened on their particular Harris system. Don't be wasting money on commercial gear that can cause you problems. Not only with the programming, but with the legalities here in GA.
Read the posts in the Rome/Floyd county thread. There can be help there.

It is a Harris but they arent dealing with LSM so its not the same, no help there.

Well then there won't be a fix anytime soon because i for a email from uniden saying nothing was wrong with their units that the problem lies within the LSM system.

Well use your google-foo and see what the root of the 'simulcast distortion' is... i will gve you a hint... it has to do with the symbol decision points, the AM component of CQPSK and what a FM receiver does to an AM signal. The problem IS 100% the lack of a proper I&Q receiver actually designed to receive CQPSK. The problem is NOT with the network... if it was, pray tel, why can actual subscribers receive and decode with out issue?

Look kayn I don't know where you live or what you do for a living but I for one live in griffin, and when the city using this crap LSM Harris system every other conversation you hear they have to ask to repeat the traffic over and over again! So again I am guessing you install these said radio systems, either way, they suck not just on scanners but, as you call it "subscribers" as well because they are having a hard time communicating! And BTW Motorola is 10X better then Harris! Have a nice day!

I live in a simulcast EDACS city, and do not work in the radio industry. I actually work in oil and gas.

BTW I will take Kenwood over Motorola or Harris all week long...

Simulcast and linear simulcast are completely different, simulcast is easily decoded! Linear is not easily decoded, no scanner made will sound good.

Very aware of that, thanks.

My local EDACS system works great, and has been extremely reliable. Most users on it are analogue, except for police, who also use both Provoice, and Provoice with DES.

Well the way you have been getting all upset when we bash the Harris system like you did, makes you seem like you work for or are affiliated with Harris, but looking at your other post you just like to instigate things on here.

 

[kayn1n32008]

Na, but I do get sick of folks that spread bad info. Like blaming the system or modularion for the craptastic scanner performance, when it is a fatal design flaw in the scanner itself. Folks are dropping 4-6 hundred on a scanner that can't properly decode a widely used modulation, then getting frustrated. When one buys a scanner they should not have to get all 'twister' with pointing yagi's to null signals, stand on one toe-pointing north-finger in their ear-two hairs straight elbow west at a 23.5 degree bend just to beable to decode a signal that is probably at saturation.

When the local first responders go P25, there has been rumblings that the police want the city sites of the provincial system to be simulcast... if it does go that way it likely will be LSM... not that it matters for listening to local law enforcement... they will be, if the trend in the rest of the country is any indication, full time encryption anyhow.

Did your google-fu turn up any info on CQPSK and why FM receivers don't decode it very well?

Hint CQPSK is used because it is much more forgiving when it comes to maximum delay spread.

I cant remeber what member explained it best, i think it was slicerwizard, why Unidens have such a difficult time with decoding CQPSK.

Its OK little buddy I don't speak your language but its clear you are agonizing over something, maybe because of your PD encryption but again can't understand some of your English.
