New Federal P-25 9600 system readout

[Curfew]

Here is the data from this site. I would like to know what i need set the pro96 to exacty ie. function 8 (fleetmap programming) , function 4 table/extended table/ normal , function 2 base, offset - and what i need to load into the extended tables of win96 for programming in case i have to do this to track this thing. Im not smart enough to figure out fleetmap or all the conversions if in fact it needs this, i only have basic knowledge of only some of the fundamentals so far.

I noticed with the win96 there are only 5 or 6 tables that can be customized in the extended tables area, hoping there is a way to squeeze 12 somehow in those if this needs to happen and then programmed into the scanner. There are 15 tables below and it appears 3 are unused. As far as how many tables and the unknown data i will need to program and have the thing track i don't know.

For those of you who think this is easy, please speak up and explain exactly what needs to happen.

Again i sure would love to track this thing without toggling scan to find someone's voice that has jumped to another frequency. Thanks, John.

This is the readout from the pro96com cc monitor-

About where is it?

 

[Curfew]

This one is military i think, im not sure yet. It's in the southeast .

All 50 states. DOD, DOJ, DHS, DOT,DOI, DOA. All departments.

I think he meant where are you hearing this particular site?

I've been curious also. The frequencies are all Department of Energy allocations, so I assumed this might be a DoE system. But johnabraham, you've been very hesitant to tell us where exactly this site is located...

A hint? What state at least?

As a side note, I had been working on trying to program the PRO-96 to deal with the Jutice Department's testbed trunked system in Washington State for a while (http://www.radioreference.com/modules.php?name=RR&sid=3509), as it has a similar base / offset table layout.
But since I found that the Uniden 796D, 396Tand 996T all track it just fine without any special tables, I've been using the PRO-96 only for the PRO96COM software.

From the information you posted, this particular site is currently only using table 12... This will make it easy to program into the Pro-96. If they start using more tables then you're going to have to have WIN96 to program it.

The channel numbers you posted are made of two parts, the table number, and then the channel number within that table. Each table can have a maximum of 4096 channels. The channel 12-2193 would be table 12, channel 2193.

The Pro-96 doesn't understand the table/channel concept. It only knows channel numbers 0 through 65535. To get the specific channel numbers you need to use, some math needs to be done.

The pro96 uses a system of high and low channel ranges. To get the low channel, multiply the table number by 4096 (in this case, 12 * 4096 = 49152). The high channel would be the low channel plus 4095 or 53247 in this case.

Now that we have the high and low channel, we need the base frequency and the spacing between channels to be able to track this site. Spacing in this case is 12.5khz, and the base is 136.0000Mhz. The offset field in the WIN96 program should be set the same as the channel Low.

So the table needed to track this site based on the information provided is:

Offset: 49152
Ch Lo: 49152
Ch Hi: 53247
Base: 136.000
Step: 12.5

If the site starts using other tables, or other sites start using other tables, then they will need to be added to the multi table area.

If the system starts to use more than 6 tables, you'll have to use two banks to be able to track it properly (one bank with some of the tables, another with the rest of them)

Mike, Bingo! Thankyou. John.

Thanks for that very easy-to-understand explaination, Mike.

Now that I know what I'm looking for I went over the PRO96COM files for the VHF Justice system near me and discovered that some sites are using just 1 table, but some are showing up to 4 tables being used.

Thanks again!

Not a problem. Some thanks also goes to Kikito (I think I spelled that right) as he and I figured out what was needed on these systems back before the first public release of Pro96Com. That seems like a long time ago now.
