• 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.

Any scanner ship with a discriminator tap already installed as a standard feature?

Actually if memory serves, the PCR1000 and 100 both have it; and for those that are hams, many 2m/440 radios have a 9600 baud output on either an accessory or on the mic jack on an unused pin that is quite suitable for things like Trunker, ect.

The Icom R-8500 has it to. Real easy to find on any scanner with O scope.

I have some Yaesu FT-8800s. Does anybody know where I get the discriminator tap on this?

The OptoCom has both a slicer output off of pin 6 (CTS) on the serial port and a discriminator output of the aux speaker output.

Hello,

The AOR AR5000 and 8600 have a pin on the ACC socket that is Discriminator Audio.

Various Icoms have it. Icom uses 9600 baud Packet Output as the description.

I will have to check them out - I don't want to mess with pins and such; I just want to plug straight in without any mods, and start decoding ;)

Sure would be nice if todays scanners BCT15, BCD996T, etc already had them installed. Surely it wouldnt cost them much in manufacturing to add them; oh well, I am off to look.

Thanks.

I own a couple OS-535 boards and I have often wondered if I could pull disrim. off the CI-V 1/8 " jacks. The board has two 1/8 " jacks labeled CI-V and a 1/8 " jack for the scout. I know the scout jack is just for reaction tunning however.

You can't pull it off the CI-V ports, but you can very easily add a headphone jack to the back of the OS-535 and then pull the discriminator audio off of the OS-535 board.
There are a couple of posts on some web sites that describe this:
http://transceiver.w8jaz.com/index.php?name=Content&pid=409

There is actually an even easier spot to tap the discriminator on the OS535 board.
I will take a picture of it when I get home, but it is pretty easy to find.

you know, i've been scanning for years, but never fully understood the "tap" thing what is it exactly used for? and what are the benefits, etc? That being said, if the benefits are so great, why isn't it standard instead of having to do a mod which violates your warranty?

Most people use it to "tap" into the unfiltered audio. They feed this data into a computer via different means to allow them to use programs such as Trunker, UniTrunker, T4WIN, etc. If you have never used any of these programs and are into monitoring trunked radio, then you don't know what you're missing. They completely take all of the guess work out of getting data for unknown systems. It also helps in confirming unknown/new tal groups and other various changes to existing trunking sites,

Not sure why manufacturers don't make it standard.

You can use Pro96com on the Pro-96/2096 to decode a 9600bps control channel using the already supplied PC/IF jack on the scanner.
