I am curious to know if the BC 396t would track Motorola type II systems better without Control Channel only. Some systems I scan, I seem to miss a lot of digital transmissions. I made sure the digital threshold was set properly, and my squelch is at level 2. Will turning the control channel only feature work?
396 works better w/o CCh only???

Wow, I had this exact same thought just the other day and wanted to ask!
I realize we're probably only talking milliseconds here, but would the 396 run quicker if I programmed every frequency from a tower and turned off control channel only mode?

No difference operationally.

A Uniden Tech told me I would get better performance on digital systems if I entered every frequency and did not use CC only mode. I never did a comparison though. I have never read on the forum of any instances where it made a difference.

While I am not a tech, and in no way arguing, I can't help but rhetorically wonder how can it make a difference? We're told that once the 396 finds a system's control channel, it locks on to that frequency until the radio is turned off. There are/were threads back near the 396's beginning where users have had multiple control channels in one system, but once they drove out of range of the "current" control channel range, they would have to turn the radio off to reset the system so it would lock onto the current range control channel to continue receiving. This is why the Pro-96 is better when it comes to multi-site trunking (multiple control channels in the same bank). Keeping that principle in mind, I don't see/understand how control channel only -vs- all system frequencies makes a difference.
Again, as I started out, not arguing, but just don't understand how one can be better than the other.

for virginia state police STARS apco 25 systems... the 396t misses anywhere from 10 to 40 percent of the transmissions when set to control channel only. The scanner has good reception, and it scans the cc, just it doesnt realize something is being broadcasted (we test this by monitoring the simulcast channel on an analog scanner). Basically everyone monitoring this system here in va has noticed this problem.
i wonder if entering all the possible freqs and turning control channel off would fix this problem, since the scanner would not be decoding the actual control channel and instead would be scanning all the voice frequencies.

GTP_04, I am sure somehow there was a miscommunication here with whoever you were talking to. Assuming we are talking about a P25 digital system you can't program it any other way than CCh mode. That is the only way the radio (indeed all P25 capable scanners) work on P25 systems. On a Motorola system, the only advantage you gain by programming all of the system/site frequencies and not running CCh mode is that you can get the activity display to show up.rvawatch said:
Not sure who is telling you this, but that is not correct. The 396T will hold onto the current CCh until it cannot hear it any more, then it will find another one in the same system. It works pretty good while moving around provided you don't mind only hearing one site at a time. And of course that old Uniden problem has been addressed in the BCD996T and BCT15 but no handhelds yet.Dewey said:

Just to clarify, I was referring to Motorola Type II mixed mode digital/analog systems, where CC only mode is optional.

oh my bad...i was thinking of a Mot 800 system. yea you're right, p25 is only "control channel only." So to answer my own question, no it wouldn't help virginia state police systems, since they can only use the control channel.
personally i really like the multi site trunking and i wish the 396 had it. if you live in an area like here, the four counties all together here share towers with each other, so some talkgroups can be heard on all towers, but some can only be heard on certain ones.
I program the CC's and the system frequencies.
CC only? The scanner needs the CC of course but I wouldn't rely on just entering in the CC and talk groups. Enter the CC's and system frequencies.
I believe it does work faster this way. Don't ask me why, it's just the way it's engineered and how the chip computes the CC information.

Just art, I'm creative. I can't seem to remember what kind of art you would call it. Defiantly not abstract as that deals with colors and no-nature objects I guess.
You do know its a IC-R3 a 2042 and a BC296D?

Lou... I'm excited to be wrong about this one. While following the threads when considering a 396 when they first came out, I thought there was a complaint that the 396 would continue to look for a signal on the same control channel of the same system until the radio was actually turned off. Again, if that's not the case, I'm glad to be wrong.
Thanks again,
Dewey
