• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

What practical data comes from a TAP

I am not new to scanners but I am new to this dicriminator tap thing. I have an old 895XLT sitting in the closet. I do have training in electrical assemby. If I spend some time to learn how to tap this thing, can I ask what useful information (in laymens terms) can I get from installing a tap? Can someone provide a screen shot of some pretty cool data that may convince me to install a tap.

I have searched the info I am requesting but it given to me in a lot of jargon I am not familiar with.

Thanks.

It appears as simply more specific data for whats going on with the frequency at a particular time and may be fun on occasion but Im not going to constantly use the computer and scanner at the same time. Ide like what I saw and would like to give it a try. Does anyone have any pictures of how to tap a 895 xlt (besides the location of the tap which I already have) and is it as simple as running a cloner line from the tap to the soundboard of my computer.

I am looking to see how the capacitor, resistor, and ground wires are run.

Check out mods.dk...there's a list of radios and scanners there that can be tapped. The 895 is one of the easier radios to tap and I believe there's a picture of the tap point on that site. Simply run a line from the tap point to an audio connector of your choice mounted on the scanner's case, then a suitable cable from that connector to your soundcard input or slicer.

A good site for general "discriminator" info is:

The author makes and seels quality interfaces as well.

(no, I'm not connected with him or his site in any way).

We actually have a wiki page devoted to the subject of data slicers - if you need one, that is - right here...

http://wiki.radioreference.com/index.php/Data_Slicers

At the bottom we've got a few US Based distributors, including DataSlicers.com. I've got one of his, and they work well.

I mentioned that you might not need a slicer. UniTrunker doesn't use one, for example. It depends on what software you will use. All software that reads a high speed data channel will need the tap - Greg Knox's pic and description are a good start for the 895.

Well I guess my main question is should I use resistor and capacitor?

If so how are they connected ?

And were is a good ground connection for the other side of the phone jack.

Chris,

The resistor is connected to the board and the capcitor is connected to the resistor with a wire from the other side of the capcitor to the lead of the phone jack. I grounded mine to a screw on the board.
