Anyone know where to get the discriminator tap done in the Toronto area.
How much do they charge?/

You can get it done at Durham Radio, As far as price, it will depend on what scanner you want it done to.

I can do a tap as well on some scanners, Ron. I've tapped my BC895XLT and 890XLT along with an old 560XLT. I haven't done a handheld yet, though.

What are the benefits of doing a discriminator tap?? have heard people talk of them, but don't fully understand the purpose.

Thanks

A discriminator tap allows you to decode certain data such as control channels for trunked systems. This is very useful. Even before trunk-tracking scanners were introduced, you could track Moto and EDACS systems using two receivers, a computer, and a "data slicer" (a simple interface into the computer), using FREE software. Audio from a control channel coming from the speaker is filtered and not suitable for decoding. The discriminator is further up the audio chain.

You can get lots of info about the system such as talkgroups, radio IDs, channels, and System IDs (for Moto systems). Some software like Trunker gives a real-time display of who's using which channels. Some multi-site systems even identify the site by name (GMCP Zone 2).

Thanks for the input guys. I would like to do it to my BC250.
Do not have any old ones to tap.

Take care
