• 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:

Here is a national link
Official Ten-Code List
Near the bottom of the page here is a local 10code & Signal listing
Pinellas County (FL) Public Safety - The RadioReference Wiki

Start here above I believe the 10 codes and dispatch signals do not change that much.
Uhhh even though there are a few 10 codes that dont change much (like 10-4 and 10-20)... signals and other codes vary widely from city to city and state to state. That is why there has been such a huge push for "plain language" dispatching from the feds. That Pinellas county wiki is for the most part useless up here.

Here is a wiki page for Lenawee county. Not sure how accurate, or out-of-date it may or may not be.
