EDACS System?

[JonL008]

I have a Pro-106 and have programmed in two different EDACS talk groups, one for Fayette County and one for Corpus Christi. I cant hear much of anything on either one. Im all over the Corpus area and hear nothing. I hear odd tones ever now and then. All I do is program a new talk group and then EDACS standard, is there something else I need to put in other then the primary frequencies that are listed for the areas?

Thanks

Jon,
For an EDACS system, you must enter all of the system frequencies listed, and, also, they must be entered in the correct LCN order.

For Fayette County, are you trying to program the LCRA system? If that's the system, you would enter all of the frequencies for the site closest to you. There's both a "La Grange 1" (site 012) and a "La Grange 2" (site 127) listed. The first one has eight frequencies, the second one lists six. Each site you wish to monitor would have to be a separate TSYS object, with associated talkgroups. If a site other than one of the two "La Grange" sites is closer, use it instead, with all of it's frequencies entered.

You cannot combine sites for EDACS (or LTR systems) in the same manner possible with Motorola or P25 systems, due to the requirement that the frequencies be entered in specific LCN order. While these two sites have the frequencies entered, with no gaps, that's not always the case. Look at LCRA site 010 (Elgin). It has nine frequencies, but the LCN 06 slot is not used. The last frequency is in LCN 10.

As for the Corpus Christi system, this continuing thread has been ongoing for several months. Apparently, one or more of the sites have rebanded, and there appears to have been some frequency realignment outside of that solely related to the rebanding process. You would enter whichever site you would be within range of, each frequency in the correct LCN slot, along with the talkgroups you wish (or a wildcard, if you wanted to hear anything and everything). To monitor all three sites of the system, you would have to create three TSYS objects, with talkgroups. Past that, I'll leave further comments as to the state of the Corpus Christi system to someone in the area.

Well that alone helps me alot there. I am only entering the primary or secondary frequencies into my scanner. I did not know you have to enter them all.

How do I know what the LCN order is?

Thanks for the help so far!

The "LCN order" is specified in the database for the LCRA system, and for Corpus Christi. The 'LCN' (channel #, if you prefer that term) is the small number you see by the frequencies listed for each site. That's the field (or "slot", as I prefer to think of it) in the scanner (1, 2, 3, whatever) you're going to enter the frequency in, either from the keyboard, or using software such as Win500 or PSREdit500.

There are some systems, such as Oncor's, where some of sites have not been fully mapped out; the LCN's are not fully determined. There are notes in that system that tell you how to spot which sites are confirmed, and which are not. For Oncor, site #s starting with 9 (900 series, in other words) are noted as unconfirmed. For LCRA, there are a handful of unconfirmed sites, at the bottom of the site listing. Like the Oncor page, the unconfirmed LCRA sites are also listed as '900' series.

Oh, so the LCN order is just that little tiny number infront of each frequency for that specific site.

Thanks for the help, very much!
