Pro-2096 Rebanding Problem Nj State Trunked System (b)

[davejl2001]

Does any one have this problem or know a way to fix this?

When monitoring the NJ State Trunked System (B) system with my Pro-2096 the Voice Channels (VC) that the control channel tells it to stop on (860.4625) does not come in clear at all, but I you manual turn to 860.46875 it comes in 100% clear. Is this becasue my scanner is ReBand ready and the system I am monitoing had not rebanded there system yet?

It sounds like an issue with the fine tuning of either the 2096 or the NJSP system, or potentially local interference precisely on 860.4625 which fades away and allows good reception on 860.46875.

It is suspected that the 2096 can survive rebanding by programming custom tables in, so unless you've done that for this system then the 2096 being "reband-ready" would not cause your problem.

The 860.4625 channel is pre-reband, so if the system is still using it then it hasn't been rebanded yet or they opted out of rebanding that channel (and it wouldn't be rebanded onto 860.46875).

I have some experience working up custom tables for UHF systems -- 800 is standardized so that hasn't been necessary -- and I have some Trunker data on Troop C. Based on that I worked up a few custom configurations you can try which hopefully will have the scanner tune to 860.46875 instead of 860.4625, but otherwise tune channels the same as it does now. You'll naturally need Win96 or a comparable program to program in the multiple custom configs.
1: Base=851.0125, Offset=0, Step=25.0, ChLo=0, ChHi=377
2: Base=860.46875, Offset=378, Step=6.25, ChLo=378, ChHi=378
3: Base=860.4875, Offset=379, Step=25.0, ChLo=379, ChHi=720

I've prepared the above without having Win96 in front of me, and without being able to experiment with it in a 96 or 2096. I suggest you save your current V-scanner before uploading the above to the scanner, to make restoration simplest. You could also delete the custom configs from Win96 and upload the system again, but loading a V-folder is probably even easier).

Please let me know how it works -- I'm really curious. If it doesn't work, I can play with it over the next few days to see if I can come up with anything else.

Thank you for your fast reply. I should also let you know that this happends on all (VC) frequencie on the system, its not only 860.4625. FYI I only have the Control Channel frequency programmed in. This is what the manual says to do for 800MHz systems with this scanner.

Only programming the control channels is fine. In the case of all the voice channels being a little off, there may be a problem with your scanner. Do you have similar issues with other channels on the 800 MHz band? Other bands?

To have the 2096 tune all Troop B voice channels 6.25 kHz above the true channel, the following single configuration should work:
Base=851.01875, Offset=0, Step = 25.0.

Since there's only one entry you can do this via the keypad -- PGM, TRUNK, FUNC-2 (just don't forget to set the 3600 CC Mode to Table -- PGM, TRUNK, FUNC-3).

The above is working for Troop C on my 96. All voice channels seem to be coming through, though reception is clearly a little off center. So it should be a system-specific workaround to your problem.

See my other post about the problems I was having on 860.4625
Sounds a lot like your problem. Mine was on a 780XLT, but everything is fine now. I think it was a propagation problem, something was getting in there.
I am sitting here in NY listening to Troop B on the 780, no problem tonite

Jim,

I made the program change and put the scanner in Table mode and a base Freq of 851.01875 and it works now!!!! The (VC) all come in very clear and the (VC)s end with
.46875 or .96875 and a few others that work fine. but this still does not tell me why this is happening. I should also add a few things, this only happends on the 800MHz band, and I am not scanning from the same location all the time I have in in my car. I had the pro-2067 before this scanner and had to get this one because my town went digital, the Freq of 866.375. when I got the 2096 I programed the same frequency in and all I would get is digtial garbage, but once I put in 866.38125MHz the Digital signal cones in clear. When I do a FCC search there is no such frequency. WHAT IS UP WITH THIS SCANNER????

At this point you may be best off going back to the RS Scanners forum to see if anyone there has had a similar problem. Off the top of my head it could be the inner working of the scanner, the antenna, the power source, or interference from your car. Since it occurs on all NJSP Troop B channels, as well as other 800 MHz channels, it shouldn't be a system-specific issue.

You might try reconnecting your 2067 (if you still have it) exactly as your 2096 is now and seeing if it has the same issue on NJSP B. Except I believe the 2067 uses larger 12.5 kHz steps in 800, so it may be harder to notice you're receiving the channels a little off center.

If you decide to send it out for repair, and if it's not still under warranty, I have used and been happy with G&G Communications. They tend to have a lot of work so the turnaround may be a little slow, and I don't know if they would work on this sort of problem with a digital scanner, but it might be worth a phone call. www.iinc.com/ggcomm/.
