The BC 246T has a limit of 200 TGs per system. I am guessing the 396 will have the same limit, because if you have anymore, the scanner will take to long to see if it has a TG that matches the one on the control channel and you could miss a transmission. UPman explains this a lot better than me, if you need a better explanation, then ask me and I will try to give a better one. The 246 does have a limit in TGs per system though. :wink:

Lifted straight out of the most recent manual UPMan Posted:

Systems: 400 max
Groups: 20 per system
Channels: up to 6000
Channels per Trunked System: up to 200

I can live with this limitation, although I still see at least one Houston Area system (Star-Net) that may require me to enter it 2-3 times (The system has over 600 TG's, and I'm monitoring less than 300 in my BC250D right now - across 3 banks). But with up to 6 times more memory, it's not as big an issue as it could be - especially with Control-Channel Only mode on the 20+ sites.

To expand on what ScanFan said, when your scanner is decoding a control channel, it has a finite time to check the decoded data against your stored TG list. If you have too many TGs in the list, by the time the scanner can check them all, it will have missed the next set of TG info on the control channel. The end result is that you start missing transmissions and people start complaining that the scanner is junk. The only solution is to use faster microprocessors in the scanners, but this raises cost. Also faster microprocessors acceptable for scanner use may not be available currently.

When you are duplicating system info, you are evaluating the control channel three times (using your example, mwjones) - one for each set of talkgroups. While this adds delays to the aquisition of a TG, no TG info is missed. You will receive the transmission of a stored TG is active on the system.

Wow, this is one of the first Uniden scanners that I have looked at and thought it looks really really good! Infact, most of the new generation scanners are good. Good stuff, I can't wait...

Btw, they are going to bring out a mobile version right? Sorta like the way Radioshack brought out the pro-96 then the 2096? If they can keep the styling good, and in a compact form (ie. single DIN slot) I reckon it will sell like hotcakes! I've always been a fan of the uniden base units like the 796d and so something along the lines of that would be great!

It says 20 "groups" per system. What is this? 20 talk groups per system? The bc296d has 100 per bank.

Or is this 20 groups of 10 talk groups a piece per bank, which equals 200 talk groups per bank! :shock: :?

I think the 20 groups per system is like the 250D. It has 10 groups of 10 talkgroups per bank (ie 100 TGs per bank). Right now, I have 2-3 TG lists per bank used for, say, fire. With this new system, I can put them all in one. Then I still have 19 more I can use. As long as I don't go beyond the 400 TG limit, I can have any combination of up to 20 lists with a system (ie bank in 396T terms).

both of you need to abandon the word "bank" from you vocab. :D the scanner doesnt have banks. and to clarify about the 20 groups, it 20 sets of frequencies/TG for each system. also... its a 200 TG limit... a 400 system limit.

No banks! :wink: The groups can have any number of talkgroups in them. You can have 1 group of 200 TGs, or you can have one group with 3 TGs, one with 10 TGs, one with 30 TGs, ect.. until you fill your 200 TG limit. The groups are user-definable (any number of TGs in any group, obviously up to the 200 limit :wink: ). Ok, all of that learning of banks and stuff in the past years goes out the door now! :wink: :lol:

Yep. I know. Banks were only useful when we had weird fixed limits on frequencies and talkgroups.

I had to read that section of the manual several times. These new radios don't have the concept of a bank. I'm assuming when the manual says "channel" they mean talkgroup and not frequency for a trunked system. Channel and freq are synonymous for conventional system, whereas a channel and talkgroup are for trunked systems.

Ok Uniden has me confused with this new scanner. I do own the bc296d and I liked being able to select each bank for the towers I want to listen to, then press the decimal to change what talk group lists I want to listen to. I organize mine with PD in one list 1-10, fire 2-10 , mutual aids 3-10 and so fourth. So it seems that there is just a quick key to scan the whole damn thing you program for that key. I hope you can enable or disable talk groups on the fly while scanning like the 296 can do.

There has to be banks for conventional with the 396 right? I will try and read the manual again but it's not really in order. You have to go from one section to another. Pita. :x :?

If you like the bank/key concept, just program your systems on the Quick Keys the same way your current banks work. Just think of it as being able to program any number of systems (3 Motorola trunks, 2 EDACS, 4 LTR, and some Conventional) on the same 'bank key'.

You can program your police in one group, fire in another, Etc.

In fact, if you want to get really retro about it, you can assign each channel a bank and channel name, have each group have XX channels, and set it up like your BC296D. You can even program only one system on a System Quick Key and use only the first 10 System Quick Keys to emulate your BC296D's bank keys.

The only thing you would really lose is the direct channel entry. Instead, you would use the RECALL to select the system, group, and channel or hit the HOLD button and scroll to the one you want.

No, there are no 'banks' for ANYTHING.

Sorry if this isn't your cup of tea, but it works out much better for 99.5% of the users. Maybe you're in the other 0.5%. On the other hand, give it a try. You may find you like it much better.

I know many services in my area don't use even numbers of TGs for their operations. Some have 2 TGs and others have 15. Some use a few channels while others use dozens. The dynamic memory really cuts down on the memory waste of using up 20 channels for 2 frequencies, or needing 51 when you only have 50 available.

Yes, it is confusing. So was trunktracking when it came out. Today, some users still have trouble understanding how to program a trunked system, but a lot more know now than knew when they came out.

As someone else said... 'This ain't your father's scanner'

While some people like the cars of the 50s, some want the benefits the more modern cars offer such as XM radio, automatic headlights, airbags, and compact size.

Uniden is certainly on the move in scanner design again. You either learn to keep up or you will get left behind - the same as just about anything else you do in life.

I guess that's enough to the analogies. 8)

I think dynamic memory is here to stay from the reaction (and volume) of the BC246T buyers and the street talk about the BCD396T. When is the last time a scanner was out of stock so frequently in recent history? They can't make the BC246T fast enough!

What are you confused about? :?

The unit has 100 System Quick Keys and 20 Group Quick Keys for each system. You can assign a system, any amount of systems, or no system to a SKQ or GQK. You can set up a Conventional System with Groups. Each SQK or GQK can be activated or deactivated.
There has to be banks for conventional with the 396 right?
There are no Banks, just Systems, Groups, and Agencies. You are limited only by memory, 200 Frequencies to one System, 200 TG's, or 200 Systems to one SQK or GQK. You can program Conventional, or Trunked Systems.
I will try and read the manual again but it's not really in order. You have to go from one section to another. Pita. :x :?
Well, if all else fails, RTFM. :lol:

Dynamic Memory - Look at it THIS WAY!

Since you use a computer look at it this way and it all falls into place :)

FOLDER - SYSTEM NAME OR SYSTEM

SUB-DIRECTORY - BANKS

FILES - CHANNELS OR TALKGROUP ID'S

The only major difference is that each system must be EITHER Trunking OR Conventional.

Quickeys for systems may turn on/off as many systems as you attach to them.

Quickeys for groups may turn on/off as many (Banks) groups as you attach to them.

ENJOY

Ok this makes a little more sense to their new design. So the Quick keys for groups are used in conjunction to quick keys for systems?

So for example I press quick key for groups number 1 which holds all my -Pd- talk groups and it will use this in conjunction to my quick key for systems number 1.

So my system quick key number 1 could be tower A and and my system quick key number 2 could be tower B. Then I could select each quick key for groups with my groups that I want to listen to providing they affiliate to that particular tower. A or b.

My current set up is like this, bank one with say tower A and all it's system frequencys. Bank two with say tower B and all it's system frequencys. I have my talk groups organized to be in relation to one another such as 1-10 -PD- and so fourth.

If this helps, a explanation to me on how to program it like I have my 296 will make me understand better. Perhaps I already figured it out from above.

So you are laughing because of my avatar. I Can't understand all the acronyms people use? I guess I just can't understand anything. :cry:

System, Group, Channel, etc. and Fire Tone Out

Just so I understand the SYSTEM, GROUP, and CHANNEL terminology and limitations, let me see if I can make this comparison in terms of conventional thinking. I could have 400 SYSTEMS with 15 channels each for a total of 6000 conventional channels. Each system of 15 channels could have 3 groups of 5 channels each. Or, I need not even use groups if I don't want to. (I realize that these are not hard partitioned, but this is for illustrative purposes only.) However, if I start adding Alpha-Numeric channel names then it reduces the number of available memories. Possibly to say 4000 conventional channels with alpha names.

Also, could I scan as many as 10 fire tone out channels for calls?

More on Tone Out

Also, this could be sort of fun on selecting tone outs. I might select mine like this:

1) National Weather 162.550 with "old" 1050 hZ (if that is possible)
2) My Fire Department "all-call"
3) My civil defense siren tone out
4) Adjacent fire department "all-call"
5) Adjacent fire department "station 5"
6) Adjacent civil defense siren tone out

etc

you 2 are giving me a headache... :D

not sure of uniden's policy, but if you 2 are really that confused, go out and buy a 246 and return it 30 days later (make sure you can do this, radioshack does), just so you get the idea of how the 396 works. other than that, unless you live near arundel mills mall in MD, thats my only advice

What would be great is if they could all be used at the same time rather than having to select only one. :-(
