Thank you to Mike for writing in and sharing with us his video detailing how he makes use of a Raspberry Pi 5, touch LCD Screen and RTL-SDR to create a portable and low cost P25 police scanner. Mike notes that the cost of his system is $250, which is a lot cheaper than a comparable $600 P25 scanner. 

Here is my latest weekend project; a Raspberry Pi 5 with an RTL-SDR dongle running SDRTrunk software. It is configured to listen to the local LAPD channels and runs great! The chip gets a bit hot so I think I need to add a fan.
