Wats fleetwide?

[altec]

I've been listening to a type II Hybrid thats not listed in the database. To my underingstanding (example: 700-0 is fleetwide?) While listening the supervisor comes on 700-0 while the other side comes on 700-7. Most of the time all the people use 700-0 but also here conversations 700-1 through 700-7. I'm use to channels but it seems like the 700-0 fleetwide channel seems to tune to everybody on the channels? The ones on their individual channels seem to stay on their own ch (ex:700-2) Am I hearing this right on the scanner?

Figuring out a Hybrid system can be difficult, a friend and I have been trying out fleetmaps on a system here local to us to see if we can get the talkgroups to settle down. We have managed to find one working so far.
But it's not uncommon for Supervisors and higher ranking officers to have access to channels that normal police officers don't have access to use. University Police here in Tennessee are set up like that.

You setup sounds like 700-0 is the common channel, perhaps Dispatch.
The others, 700-1 through 700-7 might have specialty uses. You could have Records department on one,
Detectives using another channel, and maybe even just a chit-chat channel.
Just try and figure out what is happening on each ID and see if it is consistent, then you would know if it is allocated to a records department for checking license, warrants, and other information an officer would like to know. That's the best way to figure out a system unless you know someone who has that information.

I'm not sure I followed your post, but if you're saying you hear one side of the conversation on what you think is 700-0 and the other side on what you think is 700-x (where 1h<x<Fh), I suggest you've improperly mapped a Type I or IIi block.

I agree, sound like the wrong fleet map is programmed.
And generally, I think all-call or fleet-wide is not widely used. But of course it depends on each individual system.

But if you are not hearing both side on the same channel/ID, then the fleetmap size is wrong.

What system are you trying to monitor or program.
Fleetmaps are sometimes very hard to figure out, I've been working on one over six months, and I think I finally have all but two blocks accurately figured out.

Take off the fleet map, program it as all size 00 blocks, or as a type II without a fleet map or status bits enables, then post some of what you find here.

Fleetwide

There are 4 different agencies that use this block. Three of them come in just fine on the fleetmap programmed in. Its just this one agency pops up on 700-0 and most the time thats where the conversation is. I'm just confused on how this all call or fleetwide thing works. They have channels like 1-A, 1-B, 1-C, etc. I'm thinking that 1-C would be 700-3. The trick is if someone thats on channel C is operating on that channel and someones else gets on the radio on fleetwide and calls that person the conversation goes from 700-0 to 700-3 back and forth. Thats the confusing part. I know fleetwide is rarely used but is that the way its suppose to work? No wonder its rarely used if this is the case.

Then you have your fleetmap wrong. I was thinking you were having different channel being used at different times, not why they were actually talking to each other, my mistake. Since you said there were 4 different agencies using this block, then size code 10 would be something I would start with in that one block. That size is for 4 fleets for one block.

Here is something to try that I found helpful, try setting your fleetmap to zero (0) in all you blocks. (newsalan also suggested this)
Then watch the ID's being used by the agency you are trying to fix.
If they agency's ID stays the same, then they are using Type II ID's on the Hybrid system.
If they don't stay then same, then watch the area the ID's are located using the below list. This will tell you what block they are located in.
Then just change that block one number at a time until the ID's stop changing and remains the same for the agency.
I know this is a long process, but it will eventually work out.

Block___Lower ID#___Upper ID#
0_______0000________8191
1_______8192_______16383
2_______16384______24575
3_______24576______32767
4_______32768______40959
5_______40960______49151
6_______49152______57343
7_______57344______65535

It will help... if you post What agency or company are you listening to...
What is the system id, place scanner on hold on a control channel. And post the control channels as well, it maybe in the database under something else.
I still think it's fleet map problem. Especially if it is not a public safety organization.
Still need more info on the system.

What you are describing, going back and forth is a fleetmap problem, not an all-call. The block sizes are set too small.
And if you post the type II id's, then I can translate them into a Type I id and a possible fleet map.
