Hi all,

Just wanted to post quick and let you know I uploaded a trunking scanner for 
Motorola Smartnet systems to CGRAN: https://www.cgran.org/wiki/Smartnet. The 
scanner is capable of logging the output from all conversations on the entire 
trunk in real time, and saves them to disk as .wav files sorted by talkgroup ID 
with an accompanying .txt file containing timestamp information. Please see the 
CGRAN page for further details. This program competes directly with Motorola's 
$150k logging receiver, and provides a way for users to corroborate media 
accounts and deconstruct complex emergency responses across multiple services. 
It could be used in the service of public accountability by groups wishing to 
maintain a public archive of their local system.

Please note that laws regarding scanner possession, use and recording are 
complex and vary widely by jurisdiction; use of this program may be illegal in 
your jurisdiction, and it is up to individual users to determine the legality 
of possessing or using this software in a particular way in their particular 

Please notify me of bugs, suggestions, and your improvements.
