@Motorod @majorlinux A scanner cannot transmit. That's what makes it a scanner as opposed to a transceiver.

Also, if you do transmit, you light up a big ol' beacon that says "Here I am". We #hamradio folk are pretty good at finding "hidden" transmitters. Look up "fox hunting". If we can do it, you better believe the feds can.

Furthermore, an increasing number of law enforcement agencies are encrypting their traffic now. Of course, it'd be a real shame if they're still using encryption algorithms whose weaknesses are documented in open source receiving software.
