data slicer?

[FCVPI99]

i have a Pro 92 and a pro 96 my question is this which radio would i want to use and 2 where do i get one how do i hook it up and how muach are they?

In either case (no matter which radio you used), you need to install a tap in a circuit that has the raw signal BEFORE it is amplified and reshaped by the audio stages. This is known as a discriminator circuit. This is not something I would recommend for a novice, especially on the SMT circuitry of a PRO96.

If you wish to pursue this, you can get a data slicer that will work with several applications here...
Data Slicers
The prices are quite inexpensive.

If you are trying to decode a 9600 baud system, you need not tap anything. There's a special program called Pro96Com that is set up for the PRO96 (and 2096) for that purpose.
This program can be downloaded from the link found in the supporting software section of the PRO-96 Wiki

However, if you're going to tap something, I'd probably try the PRO92. I don't know exactly where the correct tap point is, but I'll bet someone here does. If not, there's a discussion board on PRO92.com, or on the PRO92 Yahoo group. Both of these links, and some others, exist on the PRO92 Wiki

In the pro 92 you can tap the discriminator tap point by opening up the radio and near the battery compartment at the bottom there is a small metal pole that you can attach a 10 k resistor in series and then connect the data slicer. MFJ Enterprises sells a data slicer for $39.

well id liek to do it on the Pro 96 cuz i want to do a Digital 3600 system IE NWCD PS does anybody knwo anybody that knows anybody so on and so on that is in the chicago area that might want to get paid for some work on both the Pro 92(replacing LEDs) and a Pro 96 (Tap) last time i opened up a radio it was a pro 92B that the AC/DC power plug broke off well i did fix it and it worked for maybe a minute before it died

You might want to check in with the CARMA boys; they're actually in the Chicago area, but not all that far from you....and you won't need to tap the 96 to hear the NWCD system, if it's a 3600 baud ASTRO system - as long as it's not encrypted, the 96 should be able to handle it just fine. In fact, I wouldn't doubt that someone in CARMA is already doing it, and may have a .p96 Win96 file for it. Win96 can be found on the PRO96 Wiki, which I gave in a previous answer.
How to find CARMA? Well, they have their own Yahoo group, and their website is...
