The police and emergency services personnel speak using 10 codes.  This makes communications more concise.  The best known codes are "10-4" meaning "OK, I understand" and "What's your 10-20?" as in "where are you at now?"  In order to follow the conversations, you will need to know the codes.  A reference sheet is here.

Notes:

10-SEP-2008: We are seeking a partner to host scanners in Calvert County to cover Police, fire and emergency frequencies.  If you have a scanner and a PC (we use an old PII) that you can dedicate, please contact us.  We'll provide the know-how and the server.  For your trouble, we'll promote your business or organization here and in the intro audio on the scanner feed.

Need Help?

If you need help or the scanner is not working, please contact us.  Sometimes, the scanner may require human attention and our staff is unaware of the problem.  Your feedback will help us ensure a high availability of the service.  You can also get Live Help (click on the graphic to the left).
