• 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:

Are you hearing this on network first? "These shoes where black and brown" sounds like something from a pre school book.

"They took the cross town bus", Maybe I have been listening too much the last couple days, I almost have them all memorized :) I guess they are testing

It is testing, and I think the phrases have different phonetic tones.

Almost sounds like they are reading a book on-the-air.

"These shoes were black and brown."
"They took the cross town bus."
"Don't throw trash on the street."
The above messages were devised by DVSI for testing of their P25 vocoder.
The messages when encoded and decoded test and verify various aspects of
the DVSI vocoder. The vocoder attempts to eliminate constant sounds such as
a 1000 Hz test tone. For that reason you can't do something like a SINAD
receiver test (just like you can't do 2 tone paging). Instead you use the
digital voice to determine the sensitivity of a P25 IMBE receiver. The
messages get old real soon. When I go home at night, it's like having a
song stuck in your head.
I haven't heard convicts and pecans. DVSI may have developed those for
later versions of the vocoder.

Heard the same thing on my Pro-97 ...

Sold my Pro-96 a year ago.

Picked up a Pro-97 today because of the very nice price of $149

This is one of the first things I heard after I programmed my scanner. I almost think I progged JeffCO into a bank by accident (didn't mean to prog state DTRS) and heard it while I was testing the profile ... must've happened upon a broadcasting freq?


Now that I recall, I actually remember hearing it on several banks on my newly programmed, pro-97 ... so must have been a stargate etc channel? Stuff changes too fast man!
I'll try and read up tomorrow ... been away awhile.
