PRO 2067 SCANNER

[okla-lawman]

I have a pro 2067 scanner. During operation it jumps out of trunk tracking mode and scans frequecies. This is happening to two other officers who have them mounted in their patrol cars. Do any of you have
any ideas how to prevent it?? or an easy fix??

When you say it jumps out of trunk tracking mode what does it do? Is someone transmitting when this happens? If there is no transmitions then it will scan the frqs. in that bank. Also what type of system is it?

it does it on both edacs and motorola. It will appears to be scannong as normal, but then they begin to pick up in non programmed talk grops such as water sewer, fire and so on. I dont normally keep my radios groups active but sometimes it does happen. Front end overload??

 

[Eng74]

Check to see if the banlks are in the closed (-) mode and not the open (+). then you should only get the programed talk groups.

 

[okla-lawman]

they are all closed when they left my computer and when they first start to function.

I'm not familiar with the 2067, but is it possible your losing the control channel. I know my pro94 does this.

The only other thing than the open or closed fix I can think of would be that maybe the bank or one of the channels is not set to the right system. Are you programing with WIN92 or the GRE program? Did this problem start since you had the radio or after a while? The only proble I have trunking with my 92/2067 is on the Orange County, CA system but the 93/95/96 all work great on it.

It only does it some times. I am thginking one of 3 thgings. Losing control
channel (but on 4 different scanners??), front end overload from having
transmitter close by (800 mhz, though scanner antennas are feet away)
or electrical surge caused by scanner beinh on when caru is started.

electrical surge caused by scanner beinh on when caru is started.

Bingo!

I used to install a electronic noise illiminator in the positive line to the scanner and never had this problem. The raidio shop now has to install all
electronics. Any suggestions for a quick fix??

{VBSE GRIN!} Yep! Remember to turn it off before shutting the vehicle off and then remembering to turn it back on *after* the vehicle is started.

Seriously though, you'll probably need to either find or make a `PI' filter, an inductor with a capacitor on the input and the output, that you can somehow put in the line to the scanner. Since you `problem' seems to be basically a low frequency `problem' the values, and physical sizes, of the caps and inductor will probably fairly `large' so it'll probably be in some sort of box rather than something that could be sort of a `lump' in the powercord. {WAN GRIN!} It's been quite a while since I actually had to `design' one so I can't give you too good of an idea of the actual sizes.

Another thing that *might* work would be for you to get a service manual and see if they have a filter capacitor across the power. (I'd look for it directly after the power jack, or right before or after the power switch.) If there is such a critter I'd be sorely tempted to fit a bigger capacitance value, with the same or slightly bigger voltage value, in it's place. (IE: If it's a 200mfd 16VDC cap I'd consider maybe a 500mfd 16VDC cap instead.) You *might* be able to get away with it and not have to go `all the way' with the `PI' filter if you're lucky.

Since you can't make modifications to the install, just get in the habit of hitting the<SCAN> button again after starting the vehicle. Since you are using a 2067, you should be used to hitting that SCAN button :lol:

Not really.. pretty much turn it on at beginning of shift and leave it.
I am in and out of my patrol car a bunch and it is a pain to always turn
it off. I have 4 radios in my car and this is the only one it eefects. Hitting
the scan button does not always bring it back to trunker mode
